Stable Grinding Process Tailored to Your Needs

 

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.
