Main Features

1. "0"overturning moment

The adoption of a dual-cylinder guide rail pair and dual drive, featuring 2 guide rail centers, 2 drive centers, and 1 broaching center, achieves a "5-center coplanar"mainframe structure. This structure is highly symmetrical in the direction of force, eliminating the "broaching overturning moment"caused by the structure of traditional broaching machines. Invention patent number: ZL 202010920618. 5.

2. Energy saving,intelligent servo hydraulic control,closed-loop control

The intelligent closed-loop control of the hydraulic system is achieved by using a servo motor, a servo drive controller, an internal gear pump, and a hydraulic sensor.

3. Common rail,full-stroke tool transfer mechanism

The main and auxiliary slide plates are co-linear, with tool receiving and sending throughout the entire stroke. It allows for ultra-long stroke tool adjustment, ultra-high workpiece broaching adjustment, one-click tool adjustment, and intelligent and easy control.

4. Innovative "Bidirectional Operation of Equipment"

The equipment is equipped with bilateral operation conditions, allowing for free tooling adjustment and flexible switching, making it easy to operate as desired.

5. One click intelligent control

Intelligent system+embedded program+highly customized development, ready to use with parameter filling, zero programming required, safe and efficient.

6. Convenient and easy to operate

Quick tool change, automatic positioning, and operators can start practical operation with "zero foundation".
