CV-joint grinding with EHWA CBN grinding wheels

A constant velocity joint is a connecting piece between two shafts. It is used to transmit rotational torque between the two shafts, which are positioned at an angle to each other. Constant velocity joints are used, for example, in the automotive industry for powertrain shafts.

EHWA grinding tools are used to grind the windows of the cages and the raceway of the rolling elements. Here, too, EHWA and the customer have the highest demands on surface quality and grinding efficiency.
