Mitsubishi PLC + Absolute servo motor achieves full closed-loop control
To further improve the bending accuracy, this CNC pipe bending machine adopts a high-end Mitsubishi PLC + absolute servo motor. Through EtherCAT communication, it achieves full closed-loop control at the level of a precision engraving machine, avoiding the accuracy loss caused by signal interference, pulse loss, and origin loss in traditional control methods.
The bending action of this CNC pipe bending machine is driven by a servo motor, which transmits power through a precision reducer and an imported chain. After long-term use, the bending accuracy can be quickly restored by tightening the chain.
The equipment is based on Advantech's host computer as the hardware platform, and the CNC system for the pipe bending machine was independently developed. In addition to the basic functions of the pipe bending machine, the CNC system has also developed functions such as importing 3D graphics of pipe fittings for self-programming, 3D preview of pipe fittings, dynamic processing simulation, and remote diagnostic assistance.
The Type 38 multi-layer mold CNC pipe bending machine is designed with a multi-layer mold structure, which can install multiple sets of molds at the same time to be suitable for more complex pipe bending.
The machine's control system features an unrestricted self-editing mode, allowing any manually operated action to be edited into an automated workflow, greatly improving the flexibility of the equipment's operation. Additionally, interfaces for MES, robotics, and coordinate measuring machines are reserved, facilitating the expansion and development of automated workstations.
The machine's self-made parts are manufactured in strict accordance with the required materials and processes. Purchased parts are sourced from well-known brands in Taiwan and Japan to ensure equipment quality.
