The Difference Between Servo Electric Cutting and Hydraulic Cutting

When it comes to cutting products after molding in a tile press, the cutting mechanism can be powered either electrically or hydraulically. Both methods effectively perform the cutting function, but they differ significantly in terms of performance, speed, and cost.

1. Servo Electric Cutting  

Power Source: Uses a servo motor as the power source.

Speed and Control: The shear speed is controlled by a PLC, offering fast response times and high-speed cutting. This method is ideal for forming machines with rapid compression speeds, allowing the cutting speed to match the product molding rate. As a result, it can achieve the upper limit of the equipment's production capacity.

Performance: Provides superior cutting speed and efficiency, making it suitable for high-speed production lines. The precise control offered by servo motors enhances cutting accuracy and overall performance.

Cost: Typically, servo electric cutting systems have a higher upfront cost but offer long-term benefits in terms of speed and reliability. The reduced likelihood of operational issues further justifies the investment.

2. Hydraulic Cutting  

Power Source: Utilizes a hydraulic cylinder as the power source.

Speed and Control: The shear speed is controlled by a PLC, but the response time is slower compared to electric systems. This method is better suited for forming machines with slower compression speeds, resulting in a slower cutting process. Consequently, the output of the product may only meet the average production capacity of the equipment.

Performance: While hydraulic cutting can fulfill basic cutting requirements, it generally provides slower cutting speeds and less precise control compared to servo electric cutting.

Cost: Hydraulic cutting systems are usually more cost-effective upfront. However, they may require more maintenance and have a higher chance of operational issues compared to electric systems.

3. Choosing the Right Cutting Method  

Regardless of whether you choose electric or hydraulic cutting, both can meet the cutting requirements. The decision should be based on the performance characteristics of the forming machine and the specific needs of the production line.

4. Conclusion  

Servo electric cutting generally offers faster speeds, higher efficiency, and more precise control, making it a preferable choice for high-speed production environments. Although the initial investment may be higher, the long-term benefits and reduced likelihood of operational issues often make it a better option. Hydraulic cutting, while more affordable, may be suitable for slower production lines with less demanding cutting requirements.
