Conventional hydraulic presses have been the workhorse of manufacturing for decades in industrial applications such as metal forming and bending, bearing pressing, and assembly. These remain the choice for many extremely high-force pressing applications. However, the advent of servo-electric press technologies offer significant advantages in precision, programmability, energy efficiency, reliability, and flexibility compared to hydraulic machines, in a wide range of applications. This white paper examines the benefits and design considerations of servo-electric presses and explains the differences between servo-mechanical and advanced Linear Servo Press technologies for engineers developing new press equipment, retrofitting hydraulic systems, or specifying press technologies to modernize existing production lines.
On a traditional hydraulic press, hydraulic pumps generate pressure to extend the cylinders and produce force via fluid compression. Servo-electric presses, however, use brushless AC servo
motors (often with gearboxes) coupled to linear actuators to drive the press fixture. The electric actuator assembly (motor, gearbox, and linear actuator) provides the pressing force, while the control system coordinates the operation through precision programmed motion profiles. Unlike conventional hydraulic systems, a major advantage of servo-electric presses is that ram force, speed and position is continuously monitored and adjusted in real-time throughout each process cycle.
A primary reason engineers select a linear electric actuator over a hydraulic cylinder (or other press systems) is the ability to apply complex, real-time motion control. Electric actuators, when coupled to a servo motor and motion control system, have the ability to provide infinite control over position while monitoring accuracy and repeatability levels with fewer components, less maintenance, and higher levels of consistency than a traditional hydraulic system.
Modern servo motor technology enables very high continuous force capacity in a compact package, with single actuator options up to 50 tons of force. Beyond the 50 Ton range, engineers will often look at a dual electric actuator design (doubling the force capability) or a custom actuator solution. This allows linear servo-electric presses to match the force capacity and tonnage of similarly sized hydraulic machines, but also provide numerous advantages over conventional hydraulics including:
Today, there are two technologies that define servo-electric presses. The main difference between the two technologies is how the servo motor force is transferred to generate the pressing motion.
In a Servo-mechanical electric press, the servo motor drives a mechanical system such as a crankshaft, flywheel, and connecting rods to convert the rotary motion into linear motion. The press tooling is driven from the crankshaft’s reciprocating movement.
In contrast, a Linear Servo Press utilizes a direct-drive linear actuator. The servo motor directly drives a roller screw or ball screw mechanism which converts the torque into a linear thrust force. The press fixture is typically coupled directly to the thrust rod end of the screw assembly.
This white paper will focus on the benefits and design considerations for the Linear Servo Presses.
The Linear Servo design eliminates the rotary-to-linear mechanical transmission used in servo-mechanical presses, focusing the full servo motor power into direct linear thrust. This more efficient design provides significant performance benefits compared to rotary servo press mechanisms:
In summary, Linear Servo Press technology combines the best of both worlds – the high forces of similarly-sized hydraulics with the precision, speed, and flexibility of servo control. These advantages, versus traditional servo presses using mechanical force transmission, make Linear Servo technology the better choice for high-precision press applications.
Linear Servo Presses are applied in industries where high degrees of precision and controlled force application is required. Some common machine applications for Linear Servo Presses include:
These are just a few examples of the machine applications for Linear Servo Presses. Versatility and precision make this technology a vital solution for a wide range of industries and manufacturing processes where precise force control and accurate motion control are essential.
Manufacturers of Linear Servo Presses often work with a linear actuator specialist such as Tolomatic, to select or design high-force electric actuators as the cornerstone of their products. With the wide variety of servo motors, controls and standard components, a growing number of engineers are also choosing to configure electric linear actuators for their presses as purpose-built to their unique application requirements.
Evolving from conventional hydraulic presses to higher-efficiency Linear Servo Presses is helping manufacturers achieve more sophisticated production capabilities and greater productivity in a host of applications and products. This results in powerful gains in versatility, quality and throughput compared to more conventional press methods.

Because the foundation of a Linear Servo Press are linear actuators, there are numerous options to choose from. However, just as not every actuator can perform to your requirements, not every provider is equipped, or willing, to provide the answers and assistance you need. A good partner offers many ways to explore and achieve your goals, including:
When specifying electric actuators for a Linear Servo Press application, several engineering design considerations come into play. Here are some key factors to consider:
Ball screws and planetary roller screws are both types of mechanical components used in rod-style electric actuators to convert rotary motion into linear motion. While they serve the same general purpose, there are differences in their design and performance characteristics which result in varying benefits in high-force applications. Here are the key differences and benefits of ball screws and planetary roller screws:
In summary, ball screws are advantageous for applications that require precision, moderate loads at high speeds, and a more cost-conscious selection. Where press applications demand the high force, reliability, precision, and longest life, Planetary Roller Screw technology excels. High-force applications that demand high load capacity, rigidity, and durability are key drivers for planetary roller screw selection. The use of alternative cooling methods can further extend the amount of work a planetary roller screw actuator can perform within a given motion profile. When sizing, design engineers must consider the specific requirements of the application, including correct press force, speed, precision, and environmental conditions, to determine whether a ball screw or roller screw is the optimal choice for their high-force electric actuator application.
Though there are many elements to matching a motor to a linear electric actuator, it is important to decide if an integrated actuator (motor integrated into the actuator) or a non-integrated actuator/motor combination will be better in your application. An integrated electric linear actuator, such as the Tolomatic IMA series, is an excellent compact and durable option for lower force press applications. This simplifies the design as only drive and cables are needed to begin operating the actuator. Alternately, an actuator separate from a motor and drive may be beneficial. This allows for gearboxes to be placed between the motor and actuator to leverage mechanical advantage in the actuator assembly for increased force output. Whether sizing a drive for an integrated actuator or choosing a motor and gearbox for a non-integrated actuator, the tools and resources provided by both the actuator manufacturers and the drive manufacturers have made this process much simpler today than even a few years ago. Though determining electrical and mechanical requirements can be calculated long hand, a Design Engineer will be able to save time and minimize errors by using all the available tools and expertise provided by manufacturers.
Non-integrated motor selection is dependent on application specifics such as:
The motor parameters should be an output of a trusted sizing software that can then be used to then size the motor.Integrated actuator motor selection should be directly available in a trusted sizing software as it is part of the actuator assembly. Once an integrated actuator has been selected, matching the actuator assembly to a drive will be the necessary next step. There are a few important considerations that will help ensure a successful drive selection:
These pieces of information will help define drive sizing and selection to the integrated actuator chosen.
Another common design consideration in pressing applications is force control throughout the life of the press application. While force control and what the feedback can be used for is outside the scope of this white paper, understanding the different methods of obtaining force data is pertinent to Electric Servo Press design. Force feedback can be accomplished through multiple methods at varying cost levels. These options include:
Integration of simple strain gauge into fixture
Using a simple strain gauge on a fixture is the most cost-effective method of collecting force feedback. As the strain gauges do not need to be placed in-line with the force, the risk of mechanical failure is extremely low. This method is not as accurate as using a direct load cell in-line with the applied force, but the accuracy is sufficient for a number of general industrial applications.
Use of motor torque feedback
Motor torque feedback is often the next-best, cost-effective method of force feedback. There are two common methods for using motor torque feedback. First, performing a calculation of torque from current via the motor Kt value is a cheap and simple way of achieving accuracy within 10% on actual output force. If increased accuracy is needed, a load cell can be used to calibrate the actuator force output and achieve up to a 2% accuracy on actual force output. It is important to remember that additional components (reverse parallel belt motor mounts, gearboxes, couplers, etc.) and efficiency changes due to ‘warm up’ can impact the accuracy of motor torque feedback to force output estimations. These should be considered if using this method.
Rod end or fixture integrated load cells
Rod End load cells or load cells integrated into the fixture provide an alternative method for measuring force. Rod end load cells must be selected individually based on the force measurement capacity desired. These strain gage load cells typically have accuracy within 1% and should be recalibrated at regular intervals. They can be purchased as an add-on from a variety of sources and easily installed on the rod end of a linear actuator. An additional consideration when using rod end load cells is the cable must be routed appropriately during operation to prevent damage. Similarly, a pancake style (or low profile) load cell can be integrated into the press table or fixture. This method places the force sensor much closer to the point of force application and results in high accuracies (similar to and often exceeding rod end load cells). Depending on the design of the fixture, this can be relatively easy to replace or recalibrate when needed and cable routing is not an issue.
Actuator integrated internal load cell
The last option is integrating a low-profile load cell internally to an actuator. Generally, these are installed internally near the rear bearing housing of the actuator to be directly in-line with the applied force. Either piezo electric style or strain gauge style can be used internally, but they have tradeoffs. Piezo electric load cells require a special preload on internal components to reach the appropriate force range. Over time, it can be difficult keep a consistent preload as components wear. This can be accounted for to some extent with recalibration, but eventually the system components will need to be replaced if too much preload is lost. Using a strain gauge style largely eliminates the issue of preload, but both styles introduce the issue of service and replacement difficulty. Integrated load cells have an extremely strong advantage in specific applications, such as resistance spot welding, where the ability to truly follow a force profile enables high confidence in welds and reduce the total number of welds needed. In general, industrial and press applications, it is less common to use an integrated load cell due to some of the drawbacks. The load cell and actuator are designed and built together, which generally will require replacement or refurbishment of both components in the event of either an actuator or load cell failure. Integration in the actuator is often the highest cost option as most actuator manufacturers do not have integrated load cells as a standard feature in their product designs.
In many industrial press applications, the advantages provided by Linear Servo-electric press technology can offer substantial process improvements over traditional hydraulic presses. With precise, programmable control and repeatability, energy efficiency, reduced maintenance requirements, compact design, and application flexibility, linear servo capabilities enhance the performance, productivity, and efficiency of press machines, and improve the quality of produced parts and components.
When specifying new press equipment, engineers should evaluate if Linear Servo-electric press capabilities can benefit their production processes. For existing hydraulic press lines, retrofit solutions to convert to Linear Servo-electric operation may offer return on investment and value through numerous performance improvements and savings.
With Linear Servo-electric press technology continuing to advance, the advantages over hydraulic machines will only increase in the years to come. Partnering with a capable, highly-qualified servo-electric press supplier is key to leveraging the benefits for your production environment.
The metal forming machine tool, commonly known as the press machine, forms metal into a given shape. A force or pressure is applied to the metal to form or cut it. A press machine helps you form metal into any desired shape without removing chips. The only type of work the presses can handle is mass production. The main advantage of these machines is that they're the fastest and most efficient way to turn any sheet metal into a finished product. Types of Press Machine The classification of different types of press machines is given below: 1. Manual Press Machine The operator operates a manual hand press machine using a handle and presses the machine himself. The simple structure of the machine is a C frame, punch, die, handle, and guide rail. The ram rotates and goes up and down, and the force applied via the lever propels the punch in a linear motion. A manual press machine can be used for punching, blanking, and bending (for small runs or easy production). Also operating a manual hand press with proper safety is also important as it inherits alot of risks. 2. Hydraulic Press Machine The ram, pushed by the hydraulic press machine, passes many hydraulic components in the oil cylinder, typically mounted on the top beam. The hydraulic press machine has safety switches and sensing systems to guarantee operator safety. There can be two types of hydraulic press standard and non-standard, each of them has their own benefits. So choosing the right one is also crucial. The increased capacity, stroke, and customizable tonnage make a hydraulic press machine more suitable for producing complex workpieces. It is also ideal for forming, punching, and other sheet metal work. 3. Mechanical Press Machine Different kinds of mechanical press machines process sheet metal using mechanical energy. Mechanical press machines are faster than hydraulic press machines for stamping. Indeed, the mechanical press machine exerts force at different rates, making the gun stroke unsteady and hence unjustifiable for manufacturing complicated workpieces. Mechanical press machines manage repeatable processes at a swift pace and with rapid production, pushing down the cost of mass production. 4. Pneumatic Press Machine Pneumatic press machines are operated by compressed gas. The gas is compressed and expanded to increase the pressure on the inside of the cylinder. The pressure in this pneumatic press machine does not need to be changed as it is constant throughout the stroke. A pneumatic press machine should maintain the working pressure while in use; otherwise, the press stroke will be irregular, and process monitoring will become very difficult. A pneumatic press machine is ideal for bending, punching, cutting, and extrusion. 5. Punching Press Machine In sheet metal technology, punching machines punch workpieces or cut holes (or mold sheet metal). Punches and dies for punching machines come in different sizes and shapes. Machine forces are applied to the punch, which is positioned beneath the plate and moves downwards. There are two varieties of punching press machines: C-frame and H-frame. 6. Stamping Press Machine The stamping press machine creates metal sheets by applying pressure. Its work table and punches interlock to keep the plate in place while cutting or punching to the desired shape. Given its size and complexity, it needs a lot of power to drive. The stamping press machine producing the workpiece may have imperfections on the surface and poorly cleaned punching holes. Press Machinery Benefits in Manufacturing ● Increased Efficiency: In machinery pressing, manufacturing processes are controlled, and time and labor are saved in other methods. ● Cost Savings: Press machinery enables the accomplishment of accurate, consecutive tasks, which leads to minimal loss of material and minimizes errors, which reduces costs. ● Enhanced Product Quality: Precision in size and quality is assured with press machinery compared to when produced through hard work, making it superior. ● Versatility: Press machinery can be easily arranged to handle almost any kind of material that may be needed, and most of its parts can be used in many other productions, which makes it more efficient. ● Safety: Some press machines have features such as two-handed controls and emergency stop buttons that help reduce accidents. ● Customization: For instance, a business's specific manufacturing requirement can be met by customizing the press machinery to its intended use. ● Competitive Advantage: Hence, businesses spend more on new-generation press machinery and are in a position to expand production capacities and product quality, which gives them a competitive advantage. Conclusion Press machinery of various types is used in the construction and manufacturing sectors. Hydraulic, mechanical, and pneumatic presses are the most common types. Both have advantages, including increased flexibility, lower costs, and increased safety. Today, many companies are able to invest in machinery presses due to their ability to increase capacity, improve the quality of goods, and sustain competitiveness. Since press machinery is responsible for pressing, molding, or shaping materials, it is indispensable to industry development and is part of modern production. A way of looking at the creative side of manufacturing is through press machinery.
READ FULL 18-Nov- Standard vs. Non-Standard Hydraulic Presses: Which Is Right for Your BusinessHydraulic presses are a common feature of many industrial setups and are widely used in multiple sectors, including automotive, aerospace, and heavy equipment. They perform a variety of tasks by exerting a controlled force to form metal. These tasks include punching, molding, bending, and stamping. These hydraulic presses execute the metal forming work with a high level of precision. If you are equipping your manufacturing facility with a hydraulic press, you will have to decide between two versions. One is a standard hydraulic press with a common design configuration, while the other is a non-standard hydraulic press with a custom design configuration, which gives a much more streamlined performance based on your specific industry needs. Here, explore the benefits and drawbacks of each version of press so that you can make the correct decision to level up your manufacturing. What is a Standard Hydraulic Press? This type of hydraulic press is factory-manufactured and has a pre-configured design. It is constructed according to industry standard specifications. Some common design configurations include C-frame, H-frame, and four-post designs. Features of Standard Hydraulic Presses ● Fixed capacities, stroke length, and bed sizes for handling a standard material amount. ● The execution of tasks is limited to general tasks like stamping. Compression and bending ● Ready-made design that can fit a range of industrial settings Benefits of Choosing a Standard Hydraulic Press ● Inexpensive: Standard hydraulic presses are manufactured at a large scale, which large scale means that they cost less than customized presses. This is really useful for small manufacturing firms with a limited budget. ● Quick delivery and Easy setup: Standard presses are manufactured and delivered much more quickly. They can be manufactured from scratch much quicker, and most manufacturers maintain a stock of standard hydraulic presses that are ready to be shipped. ● Easy to maintain: Replacement components for standard hydraulic presses are widely available, and there is a large aftermarket of used parts, making it much easier to repair and maintain standard presses. Ideal Fit for: ● General-Purpose actions: metal forming, such as punching and stamping, do not require special or unique measurements and shapes. ● Mass production: where the products have exact dimensions and high output output. ● High Tolerance: where measurement variation is not acceptable during a production run. What is a Non-Standard Hydraulic Press? This kind of hydraulic press, also known as a custom hydraulic press, is engineered for a specialized application and has a specific design. Custom presses have unique features in every aspect, from frame type to tonnage, stroke length, bed size, and user interface. Features of Non-Standard Hydraulic Presses ● Tailored design: Custom hydraulic presses are specially constructed to make highly specialized products with unique shapes, dimensions, and sizes. ● Advanced features: Custom hydraulic presses also come equipped with special features like additional sensors and custom controls that adjust a non-traditional production cycle. ● Specialized Configuration: Customizations for specific requirements like material handling or giving shape to a part with complex geometry are only possible with a non-standard press Benefits of Custom Hydraulic Press ● Crafted for High Tolerance: Such presses have higher than average precision to handle specialized tasks for niche manufacturing. ● Highly Adaptable: Variable speed settings, sensors, and automated loading systems are regularly seen on non-standard presses. ● Greater Efficiency: A non-standard press is made for a specific manufacturing need and is hence capable of higher productivity, as it has faster cycle time and better accuracy. Ideal Fit For: ● Non-standard Production: Products with a unique shape require presses with different stroke lengths and bed sizes that are not commonly part of a standard press. These require a specially made hydraulic press. ● Industry-Specific Quality Control: Many sectors, like aerospace and medical manufacturing, have their own quality standards that require much higher precision than other products. A non-standard press is designed to meet such exacting standards much more easily. ● Large dimensions: Many irregular shapes of objects cannot be handled by standard presses, and custom presses are seen as more useful in such manufacturing. How To Select The Right Option? A decision regarding what to choose between a standard and custom hydraulic press all boils down to assessing your business's needs. Ask yourself: What is the volume and quality of my production? High-volume, commodity, or standard-product jobs fit better with standard presses, while customized services are better suited to custom applications. If your processes change in the future or you may require one-of-a-kind specifications, how critical is flexibility? What is my budget and timeline? Standard is the way to go if you need a press immediately and at a lower cost. A custom press might pay off in productivity and long-term value if the budget and lead time are flexible. Conclusion Overall, each standard and custom hydraulic press has its place in the modern manufacturing landscape. The high ease of deployment in standard presses makes them ideal for faster cost efficiency where production needs are predictable and repeatable in business. Although more expensive and time-consuming, custom presses offer essential, tailored precision and unique capabilities required in specific manufacturing. Hence, opt for the one that will strike a chord with the needs of your business, achieve its production results, and cater to growth aspirations so you optimistically utilize your investment in the hydraulic press.
READ FULL 30-Oct- Safety Tips and Guidance For Manual Hand PressManual hand press are the workhorses of various industries, and are flexible enough to adjust to every manufacturing setup ranging from a small workshop to a larger manufacturing plant. They can be versatile and affordable for most tasks such as shaping, assembling, bending, or pressing materials. However, being machinery, a manual hand press comes with its inherent risks if used improperly. Understand The Basic Safety Of Hand Press Before using any hand press, you should know what your device looks like and how it should work. Hand presses range from small to large with a variety of shapes, so the first thing before you start using your press is to read the manufacturers' manual. It can tell you how to put the tool together, about its maintenance, how you should handle it, and especially about the maximum pressure the tool can withstand or even about the maximum load weight it can handle. ● Know the machine's capabilities: Every hand press is designed to withstand a specific amount of pressure, so over-straining may result in mechanical breakdown or injury. ● Identify Potential Dangers: Be aware of pinch points, sharp edges, as well as any possible ejection areas where materials could become unsecured. Knowing the mechanics and the limits of what your hand press can do safely is the key to effective and safe operation. Use Right Personal Protective Equipment With a hand press, right personal protective equipment is necessary. Given its application, the possibility of pinch injuries, flying debris, and cuts can be there. All of these can be prevented with the right PPE. ● Eye Protection: Eye protection would protect from flying debris and chips in case of breakage when working with metal and hard materials. ● Gloves: The anti-cut gloves will guard against sharp edges and accidents in which the operator unintentionally scrapes himself. ● Steel-Toe Boots: In case the materials get very heavy, steel-toe boots can prevent accidental drop of the material. ● Ear Muffs: Although manual hand presses are much quieter as compared to automated, yet hearing protection can be provided. It is a good thing for a noisy workshop environment. Most general injuries that may result from a hand press are prevented by proper PPEs. Safe Working Area Preparation A proper working area is one of the major requirements for safe operation. Working in a clean, systematic, and well-illuminated working area highly minimizes the chances of an accident. ● Stable Non-slip Surface: A hand press should be mounted on a solid, non-slippery working bench so that during working, it doesn't shift. ● Clear Area Around the Press: The area about the hand press should always be clear of clutter. Loose items may cause an individual to trip or inadvertently become a projectile if he or she is obstructed by them in front of the press. ● Adequate Lighting: Adequate lighting will enable the operators to see clearly all parts of the machine so that their hands and materials do not enter wrong places. ● Accessible Emergency Stop: Most hand-operated buttons or other types of manual stops don't have an emergency stop available, but understanding how to quickly shut off or de-energize it will be an excellent prevention from injury when disaster strikes. A clean, clutter-free, and neat work station will eliminate distractions and make it possible to focus on the job at hand, free from any interference. Inspect equipment regularly This ensures no untimely breakdown which could lead to injury. The operator should check rapidly and make sure the hand press is in good working order before use. ● Check for Wear and Tear: Check parts which move for signs of wear, such as cracks or rust, or general damage that may affect how they function. ● Lubricate moving parts: Most hand presses require friction-free movement for excellent performance. By following the manufacturer's guidelines to lubricate, the machine will continue to operate exceptionally well. ● Check loose bolts and screws: Vibrations often cause frequent use to loosen bolts and screws. Check all bolts and screws for tightening. ● Replace any broken parts: Replace the part if it breaks to avoid using the hand press. The chances of an accident increase if you are working with a compromised machine. Maintenance prevents malfunctions which can lead to accidents. Utilize Safe Technique Safe technique is the basis of proper working with a hand press. Poor posture, hand positioning, or technique will result in injuries from minor cuts to severe crush injuries. ● Hold hands away from the press points and other moving parts of the press to avoid pinch injuries. ● Where possible, clamps and jigs provide hands-free operation and a reduced chance of injury. ● When the material is not giving way to expected pressure, check for potential problems instead of forcing it. ● Position the hand press and workbench so that it prevents you from bending or overreaching, thus leading to strain and injury over time. Proper techniques for work also ensure safety but enhance the quality of the work being performed. Don't Overload the Hand Press You should not overload the hand press because too much pressure or usage on materials can cause the equipment to break and result in injuries. ● Understand Maximum Load: The manufacturer has a recommended manual of what your hand press load capacity is. ● Work at Capabilities of the Press: Do not use hand presses with materials or jobs for things that are beyond design spec. If the press seems to be resisting then most likely the material may have been too thick and also too hard. ● Refrain Using Extensions for Extra Force: For additional leverage on the handle, do not use the added tools such as the use of pipes or a bar to get more out of the hand press; the breakage and perhaps causing injury can occur from doing that. Staying strictly within the design load rating guarantees the press to work at peak capacity and safety. Undergo Comprehensive Training Training needs to be sufficient, and better at the training sites of freshers. Workshops at periodic intervals of refresher courses about the latest safety measures implemented at any place would surely get the entire workforce educated and aware about the safety requirements. ● On-the-job Training: The supervisor has to provide on-the-job training on how the machinery could be operated safely and serviced properly. ● Encourage questions: Promote a culture in which operators are comfortable asking questions or seeking help on the hand press. ● Supervision for New Operators: New operators should be supervised until they are competent at safe operation. Conclusion Using a hand manual press is quite safe and efficient if certain guidelines are followed. You know, with these safety measures: knowing the machine and its components, proper personal equipment, keeping the environment clear, conducting regular inspection schedules, perfecting technique practice, keeping your eyes peeled, and preparing for an eventuality.
