Product Introduction

The core of this CNC Bus Bar Bender's bending unit lies in its advanced full-servo electric cylinder direct-drive technology. By directly coupling the motor to a precision ball screw, digital commands are converted into highly accurate linear motion, simplifying the power transmission chain and providing multiple fundamental advantages:

Unlike traditional hydraulic systems, the servo system eliminates uncertainties caused by oil temperature, pressure fluctuations, and valve control. Millisecond-level closed-loop feedback ensures that each bend's angle, depth, and speed are entirely program-controlled and unaffected by environmental factors. This guarantees extremely high repeatability and angle consistency, with performance remaining stable regardless of workshop temperature variations or prolonged operation.

The system has no wear-prone hydraulic seals or complex valve assemblies, effectively eliminating the risk of oil leaks, maintaining a clean working environment, and significantly reducing unexpected downtime.

Key Performance Features

The core drive delivers linear motion at up to 1 m/s with millisecond-level dynamic response. Compared to traditional drives, this drastically reduces auxiliary time between operations, allowing the CNC Bus Bar Bender to focus on effective processing and dramatically increasing production efficiency.

Direct-drive linear motors provide direct, intermediary-free power transmission, offering inherently high linear control and enabling long-term stable execution of complex, precision motion trajectories.

Bending Workstation Features

The servo electric cylinder and linear motor are fully controlled by the PLC system. Operators simply input the dimensions of the desired bend, and the system automatically calculates the required unfolding and compensation data, converting it directly into precise bending operations.

Basic bending model library: (By inputting data for each segment based on the model library graphics, automatic positioning and manual assisted processing can be achieved.)
