Features

Workrest is compatible with a wide range of workpieces
Fixed-bed-type workrest which supports changeover is best for smalldiameter workpieces.
Fixed-bed-type workrest supports Ø12mm and smaller diameters.
Changeover to thin-type regular workrest is also possible.
One unit can grind a wide range of workpieces by using fixed-bed-type workrest for small diameter ball screws. and table-mounting-type workrest for medium and large ballscrews.The built-in motor greatly expands the angle domain of the swivel wheel head.
Drum-type swivel wheel head and built-in low-vibration spindle.
The drum-type swivel wheel head provides high-accuracy grinding and simultaneously swivels the grinding wheel and dresser ±45°. The wheel spindle uses a built-in motor.
Improved maintainability and eco-friendly machine.
We eliminated drive belts and adopted grease lubrication for the wheel spindle. This reduces air consumption volume by 50%.
