Diff Spherical Surface and End Face Cutting Machine

Diff Spherical Surface and End Face Cutting Machine WDM12B-4ATT

4 mounted spindles. Processing of the sphere and the end faces of the internal diff is possible with this machine. Faster, more accurate, and space-saving. Compatible with various factory line layouts.

Reliable Bar Slide Spindle Structure

Bar slide structure without LM guide or box slide.It is resistant to the chronological thermal displacement, maintains high durability and vibration resistance, and provides high accuracy.Cp ? 1.66 or higher as a comprehensive product finish accuracy.

The bar slide has a wider pressure area than the box slide. This means that it is effective in all directions leading to higher rigidity and greater durability. The highly reliable bar slide will remain operational for 15-20 years.
The left housing advances using hydraulic pressure and holds the cutter pressed against the right housing at a constant pressure. R-side servos precisely positions and performs an interlocking processes.

Equipped with four tool pickers
