What Is a Servo Press

A servo press is a machine that has a set of motors that move in response to an external input. These motors can be electrical or hydraulic. They can be programmable, so you can adjust their speed and direction as you need.

Servo-hydraulic presses

Servo-hydraulic presses are used for various applications in industrial manufacturing. They are known for their high performance and reliability. Their benefits include a fast forming process, precision, and minimal maintenance. These presses can be used in metal forming, composites, hot forming aluminum, and press hardening.

Compared to conventional hydraulic presses, servo-hydraulic presses are able to produce up to 20% more efficiency. This enables manufacturers to improve production rates and reduce costs.

Servo-hydraulic presses feature a closed-loop system that continuously controls slide movements. The system also actively governs the parallelism of the slide to the press table. It quickly corrects deviations, contributing to high forming precision.

Using a servo-hydraulic press can also lead to lower energy consumption. A closed-loop system helps to control the temperature of the hydraulic fluid, thereby minimizing noise. In addition, the system can also help to prevent heat loss.

Some servo-hydraulic presses use a closed-loop feedback system to provide an extremely high level of accuracy. As a result, these machines are able to form intricate shapes and minimize material waste.

Servo-electric presses

Servo-electric presses are used for a wide range of applications in the assembly industry. They provide an alternative to hydraulic systems and require less maintenance. In addition, servo-electric presses offer increased energy efficiency.

Compared to hydraulic presses, they use about one-fifth of the hydraulic system cost. Additionally, they run cleanly and quietly. Furthermore, servo-electric presses are incredibly reliable. They can achieve the desired press force at any point of the stroke.

Servo-electric presses are available in a variety of models. Depending on the model, the thrust force can be as high as 50,000 lbs. They are also more flexible than hydraulic counter parts.

Unlike hydraulic presses, servo-electric presses do not need hoses, oil tanks, or hydraulic power units. These servo presses are designed to be built into different types of frame structures. Some models are designed for inline installation.

Moreover, these servo presses are ideal for light duty assembly applications. For example, they are suitable for press fitting, clamping, and joining.

EVOx press

The EVOx servo press line from Beckwood Press Company is a low maintenance, energy efficient alternative to hydraulic systems. Available in a variety of models ranging from 0.5 to 50 tons, these presses are designed for a wide range of applications including light-duty assembly, spring testing, staking, riveting, crimping, clamping and punching.

This is a new way to look at assembly operations. It integrates the assembly process with the quality assurance and process control elements. Also, it’s a bit more OSHA-friendly, reducing slip and fall accidents.

EVOx presses boast a range of innovative features and technologies, including positional feedback, a programmable control system, and an innovative heat-free, electric actuator. These features are not only convenient for operators, they also provide superior performance.

For example, the EVOx servo press has an advanced motion control system, enabling it to monitor motion to ensure high-quality part production. Additionally, it has a graphical display of a test run waveform allowing for repeatable precision.

Dangers of oversizing a servo press

A servo press is an excellent tool for automotive manufacturing. It offers high productivity, reduced downtime, and lower energy consumption. But the technology also comes with risks. For example, oversizing the press can create safety hazards.

Servo presses can be programmed to dwell with a load at any point in the stroke. This can improve the production process and reduce the risk of snap-through loads. They can also be tailored to meet unique requirements.

Oversizing a servo press can have negative effects on the quality and safety of parts produced. The press may not be able to maintain the correct speed or be stalled when the load exceeds the rated capacity. In addition, overtaxing the press can damage tooling.

To ensure that your servo press is sized correctly, consult Lakewood Automation, an expert in servo press integration. They can help you determine the type of motor you will need and how to manage its energy.

You should work with your supplier early in the design process to establish the parameters of your pressing application. Most suppliers have experience in helping you make that decision.
