Internal grinding wheels and superfinishing tools with CBN, diamond, silicon carbide and corundum abrasives

 

Ball screws may improve the performance of virtually any application. These state-of-the-art devices are mainly used in machine tools such as lathes that require workpiece or tool carrier positioning or in power-steering systems found in almost every car.

 

Schmeier provides special CBN tools particularly suited to the intricate process of ball screw grinding. The use of a new highly porous bond and unique grain compositions allow for burn-free and stable grinding of ball screw nuts.

 

 

Ball screw grinding case study:

 

Two-stage grinding operation (roughing and finishing) with two grinding spindles:

 

Spindle1 =roughing

Spindle2 = finishing

 

Grinding procedure: spindle inclination according to lead angle

 

Coolant: oil
