CNC machining Center

High precision CNC machine was used to process all parts, All parts are standard and interchangeable, Multi – axis linkage, the shape and position tolerance requirements are ensured.

Worm and Gear design

Choose worm gear and worm with a high speed ratio to make adjustments easier and save time, With self-locking function and precise positioning, The adjustment gap is smaller than with a traditional screw, fine-tuning is more accurate, and product quality is easier to control.

Roller

The rollers can be ground 3-5 times due to their high machining precision and high wear resistance, High quality forging raw materials, secondary forging CNC processing, high density and hardness.

Quick-change system

This design perfectly solves the problem of the customer’s limited site, limited investment budget, and numerous product specifications, Offline pre roll change achieved, saving 80% of roll change downtime.

4-Turkey head design

Designed specifically for high-quality square tube orders, It has stable deformation, a high surface quality of square tube, and few deformation marks.
The steel pipe’s rounded corners will not be stretched, and its strength is high, reducing the number of times the rolls are ground due to wear.
