Darmann implemented the use of wheels having coolant release holes that helped to keep the wheel/part interface free of debris. This new wheel design improved part quality and reduced process costs resulting in:
A 30% reduction in hand polishing
A 25% improvement in overall productivity
Improved quality and part appearance by reducing scratching on the surface of the part
