Equipment Highlights

Spiral broaching machines, intelligent, high efficiency, high precision, high stability and environmentally friendly.Advantages and features of broaching machine:

1. Highly symmetrical design of the main structure, with a 5-centred co-planar of the guide center, drive center and broaching center.

2. Helical rotary C-axis with "0 backlash" high precision gearing

3. Spiral drawing linear axes (X1, X11 axes) + rotary (C axis) with high resolution encoder feedback for fully closed loop control

4. High flexibility in the form of dual-sided operation.

5. Kneadable, safe tool lifting devices.

6. Automatic cooling and chip flushing systems with precision filtration.

7. Full envelope skeleton noise-reducing safety protection system.

8. The use of a deep secondary development of the Siemens 828D CNC.

9. Tool and fixture change aids reduce the intensity of manual operations for tool change; enhances operational safety and tool change efficiency.
