Abstract
A stone guide for guiding the honing stone of a superfinishing machine. The stone guide receives a honing stone unit which comprises a honing stone and a honing stone holder. The honing stone holder defines a shoulder and a contact surface. The stone guide includes a piston and a piston rod, at one end of which there is disposed a contact surface, and a rapid-clamping device displaceable in the piston rod. The rapid-clamping device includes a further piston, a further piston rod connected to the further piston and a clamping element which defines a shoulder. Both pistons are displaceable by means of a pressure medium such that displacement of the piston effects lowering of the honing stone unit unto a workpiece and the upward movement of the further piston effects engagement of the contact surfaces.
