Servo presses are instruments with high automation and complex precision. They are widely used in the electronics industry, motor industry, home appliance industry, and machinery industry. Because the structure of the servo press itself is relatively complex, its purchase is also a process that requires repeated consideration. Here are a few points to pay attention to when purchasing a servo press.
Link to S-T Intelligence
First of all, it depends on the precision of the servo press you need. Accuracy refers to the accuracy with which the pressure and position reach the specified point and stop. It is related to the resolution of the driver, the resolution of the pressure transmitter, the accuracy of the servo motor and the response speed of the reaction equipment. The servo press has matured through the complete set of integrated control of servo motor and drive control, and its repeatability is getting higher and higher, and its application field is getting wider and wider. If you need a servo press with high precision, you should focus on the configuration when choosing a servo press.
The second depends on the structure of the servo press. Generally, the structure of servo presses produced by manufacturers is not single. The common ones are four-column, single-column, bow type, horizontal type and frame type. The four-column structure is economical and practical. The horizontal type is commonly used in the operation of longer products, and the frame type has the advantage of large tonnage, so the selection of the structure should be determined according to the size and structure of the product.
Third, the functions of the servo press include forging, stamping, assembling, assembling, pressing, forming, flanging, shallow pulling, etc. Different functions are often different in structure, so according to the suitable product process Requirements to select the right servo press is also required to do the work.
Fourth, determine the required servo press, the manufacturer, service and price are also the key, try to buy from a powerful manufacturer like Xinhongwei, one is not worried about the quality problem, and secondly, even if there is a problem, the manufacturer has it. A complete set of services.
Problems that need to be paid attention to when maintaining the servo press
When it is necessary to test the accuracy and performance of some building materials and metal materials, equipment such as servo presses are usually used. Many people will be curious about what this is? Simply put, it is a good combination of optics, mechanics and High-precision instruments for electricity. For example, in the experiment of a large-scale quality inspection unit, the servo press will run under high load. Since most of the experimenters lack corresponding maintenance experience, some problems will often occur. Let’s talk about the servo press. Matters needing attention when using and maintaining:
1. The lead screw and transmission part of the servo press should be regularly lubricated with lubricating oil to prevent dry friction.
2. Cooler: The scale of the air-cooled cooler should be cleaned regularly; the water-cooled copper pipe should be observed regularly to see if there is any water leakage.
3. Regular inspection of components: All pressure control valves, flow control valves, pump regulators and signaling devices, such as pressure relays, travel switches, thermal relays, etc., should be regularly inspected.
4. The fasteners of the servo press should be locked regularly: the vibration after the fracture of the sample tends to loosen some fasteners, so it should be checked regularly to avoid large losses due to loosening of the fasteners.
5. Accumulator: Some servo presses are equipped with an accumulator, and the pressure of the accumulator needs to be kept in a normal working state. If the pressure is not enough, the accumulator should be supplied immediately; only nitrogen is charged into the accumulator.
6. Filters: For filters without clogging indicators, they are usually replaced every six months. For filters with clogging indicators, continuous monitoring should be performed. When the indicator light alarms, it needs to be replaced immediately.
7. Hydraulic oil: It is necessary to check the oil tank level regularly and fill it in time; the oil should be replaced every to hours; however, it is important for Zui that the oil temperature should not exceed 70 °C, and when the oil temperature exceeds 60 °C, it is necessary to Turn on the cooling system.
8. Other inspections: We should be vigilant, pay close attention to details, detect the occurrence of accidents as early as possible, and prevent the occurrence of major accidents. This is especially true at the beginning of Zui’s operations. Always be aware of leaks, contamination, damaged components and abnormal noise from pumps, couplings, etc.
9. Use a suitable fixture to complete the corresponding test, otherwise not only will the test not be very successful, but the fixture will also be damaged: Electro-hydraulic servo testing machines are generally equipped with fixtures for standard samples. If you want to do non-standard samples, such as twisting wire, milled steel, etc., need to incorporate proper fixtures; there are also some super hard fixtures. Materials such as spring steel need to be clamped with special materials, otherwise the clamp will be damaged.
10. Cleaning and cleaning: During the test, some dust, such as oxide scale, metal chips, etc., will inevitably be generated. If it is not cleaned in time, not only parts of the surface will be worn and scratched, but more seriously, if these dusts enter the hydraulic system of the servo press, a shut-off valve will be generated. The consequences of holes, scratching the surface of the piston, etc. are very serious, so it is very critical to keep the testing machine clean after each use.

The electronics industry demands micron-level accuracy, and servo presses deliver exactly that.
They are widely used for crimping connectors in devices like smartphones and laptops, where forces as low as 0.1 Newtons must be applied to avoid damaging tiny pins.
In printed circuit board (PCB) assembly, servo presses embed components without warping the board—a common issue with traditional presses. This capability ensures defect rates stay below 0.05%, even for high-density designs.
Semiconductor packaging is another critical application; servo presses seal chips with precise pressure control, preventing micro-cracks that could render expensive components useless.
In aerospace, servo presses handle materials that demand extreme precision and durability.
For instance, turbine blades made from heat-resistant superalloys like Inconel require forging tolerances within ±5 micrometers to meet aviation safety standards. Servo technology achieves this by adjusting ram speed and force mid-cycle, compensating for material variations.
Similarly, medical device manufacturers use servo presses to shape titanium implants for hips and knees. The machines’ cleanroom-compatible designs and ability to apply ultra-low forces ensure biocompatible surfaces free of contaminants.
Syringes, inhalers, and surgical tools also benefit from servo-driven assembly lines that prioritize sterility and precision.
Beyond traditional sectors, servo presses are fueling innovation in cutting-edge fields. Additive manufacturing now leverages servo-driven compaction systems to prepare metal powders for 3D printing.
Companies like SpaceX use these systems to create high-density rocket components with minimal porosity. In renewable energy, servo presses stamp solar panel frames and wind turbine bearings, where tight tolerances are vital for longevity.
Even luxury goods manufacturers employ servo technology to craft intricate watch components or designer eyewear, achieving mirror-like finishes that manual processes cannot replicate.
Looking Ahead
From EVs to life-saving medical tools, servo press technology bridges the gap between mass production and precision craftsmanship. Its adaptability continues to unlock new possibilities, making it indispensable in both established and emerging industries.
Servo presses consume significantly less power than hydraulic or mechanical presses.
Traditional hydraulic systems run continuously, wasting energy even during idle periods. In contrast, servo motors activate only when needed, slashing energy use by 30–50%.
Servo presses achieve micron-level accuracy through closed-loop feedback systems.
Sensors monitor force, position, and speed in real time, automatically correcting deviations. This ensures consistent output, even for high-tolerance tasks like medical implant forming (±5µm accuracy).
Traditional presses, with their mechanical linkages or hydraulic fluid lag, struggle to maintain such precision, often requiring manual adjustments and producing higher scrap rates.
With servo presses, manufacturers can switch production batches in minutes.
Pre-programmed force and speed profiles allow seamless transitions between materials—from brittle carbon fiber to malleable copper—without hardware changes. Hydraulic and mechanical presses, constrained by fixed cycles, lack this agility.
Servo presses eliminate complex components like clutches, flywheels, and hydraulic pumps, which are prone to wear. Fewer moving parts mean:

Decision Checklist:
☑️ Test the press with your specific materials/tools.
☑️ Verify compatibility with existing automation (e.g., robots).
☑️ Review warranty terms and technical support options.
Regular maintenance ensures servo presses operate at peak performance while extending their lifespan.
Start with daily lubrication of the ball screw and linear guides using manufacturer-approved greases to minimize friction and wear. Monthly alignment checks are critical—misaligned rams or dies can cause uneven force distribution, leading to part defects.
Software updates should be prioritized to keep the controller’s firmware and safety protocols current. Many modern servo presses allow over-the-air updates, reducing downtime.
Finally, conduct bi-annual inspections of electrical connections and cooling systems to prevent overheating. A clean workspace free of metal debris and dust also safeguards sensitive sensors and motors.
Even well-maintained servo presses may encounter occasional hiccups. Overheating motors often stem from blocked ventilation or excessive loads.
Calibration errors typically arise from sensor drift or mechanical wear. Recalibrate the load cell and encoder quarterly using certified calibration weights. If the press exhibits inconsistent force output, inspect the ball screw for wear or contamination—replacing it early can prevent costly downtime.
Sensor malfunctions (e.g., false overload alerts) are frequently caused by dirty or misaligned sensors. For persistent issues, consult the manufacturer’s diagnostic tools to isolate faults in the control system.
Proactive Measures:
The next generation of servo presses will leverage AI-driven predictive analytics to optimize performance. Machine learning algorithms analyze historical data to forecast component wear, enabling maintenance before failures occur.
AI also enables adaptive process control—presses automatically adjust force and speed based on real-time material feedback, ideal for handling variable alloys in aerospace manufacturing.
As industries prioritize decarbonization, servo press manufacturers are developing energy recovery systems that capture and reuse kinetic energy from the ram’s downward motion.
Eco-friendly designs are also emerging, such as presses built with recycled materials and lubricants that minimize environmental impact. Companies like Tesla are pushing suppliers to adopt these green technologies to meet net-zero goals.
Hybrid systems combining servo presses with collaborative robots (cobots) are redefining safety and efficiency.
Cobots handle tasks like part loading/unloading, working alongside humans without safety cages. Future systems may feature voice or gesture controls for seamless human-machine interaction.
The Road Ahead
By , servo presses could become fully autonomous, self-optimizing units embedded in smart factories. Innovations like digital twin simulations (virtual replicas for testing press settings) and 5G-enabled remote control will further accelerate adoption.
