The most important criteria for bending and press machines are high machine utilization, high speed, and high precision. The spindle drive for moving the slide is moved electrically or hydraulically.
Electric press brake are either servo motor-driven (ball screw) or belt-driven (belt and pulley) spindle drives. If the forming process uses hydraulic drive, Mito recommends a servo-hydraulic drive solution.
Whether you choose an electric or servo-hydraulic spindle drive, MYT, as a manufacturer of drive units and automation systems, will leverage its extensive experience in machine equipment to assist you. We provide the services you need – from individual motors and components to integrated drive systems.
As a total solution provider, we offer comprehensive services from planning to commissioning and maintenance.
Pure Electric Main Drive Unit: Spindle or Belt Drive Unit
The MYT drive system, employing a pure electric spindle, consists of a servo motor and a servo drive unit. Compared to traditional hydraulic solutions, it offers numerous advantages beyond higher energy efficiency and productivity, such as greater environmental compatibility due to its oil-free design, lower noise pollution and maintenance costs, and higher precision.
Servo Hydraulic Main Drive Unit
In the case of a servo hydraulic drive unit, hydraulic pressure is supplied via a servo pump, with regulation functions integrated into the pump’s frequency converter. MYT is responsible for the design of the entire drive system, including the motor, servo drive unit, and, where necessary, the pump. The pump and motor can be connected via couplings and pump brackets, or directly via the pump itself.
The servo hydraulic technology module is directly integrated into the servo drive unit, fundamentally ensuring that the advantages of the servo hydraulic system are fully realized. The core software includes flexible pressure and volumetric flow rate regulation with a regulator cycle time of only 125 μs, ensuring optimal dynamic performance and accuracy. Through intelligent pressure pre-control, the regulating system can adjust for different hydraulic segments, thereby achieving excellent pressure regulation performance.
In addition to superior regulation performance and simple operation, MYT’s latest servo hydraulic system software V2+ also provides a wealth of protection and monitoring functions, further enhancing system performance and reliability.
Advantages of Servo Hydraulic Spindles Compared to Traditional Hydraulic Drives
Compared to traditional hydraulic or mechanical spindles, servo hydraulic drives offer significant advantages, such as higher productivity and greater flexibility. With powerful servo motors, pumps, and servo drives, optimizations can be made in cycle time, noise emissions, energy consumption, and environmental sustainability.
