Thread Grinding Machines GAS, GIS, GUS

Application Range	Tooling Concept	Application Examples

 

Application Range GAS External and internal ball screw tracks for automotive steering systems, worms. Drive worms. GIS Internal ball screw tracks for automotive steering systems. GUS External ball screw tracks for automotive steering systems, internal ball screw tracks for automotive steering systems. Note: The GUS version has exchangeable grinding units for external and internal threads.

Tooling Concept Non-dressable CBN profile grinding wheels consisting of a hardened and precision ground steel base body with a single layer of CBN galvanically applied to the wheel form. Note: The key advantage of the KAPP tool concept using non-dressable CBN profile grinding wheels lies in the excellent wear resistance of the CBN layer, which makes it possible to grind a large number of workpieces at consistently high form accuracy without dressing the wheel. For high volume productions of ball screw type automotive steering system, this results in significant cost reduction as it minimizes the classifying process and, equally important, allows closer tolerances, which improves both the efficiency and rolling action of the components because of reduced backlash.
