Claim:
1. An apparatus for polishing workpiece surfaces, the apparatus being removably mountable in a tool holder of a program-controlled machine tool having a work spindle to which the tool holder is connected, the machine tool having a source of pressure at the tool holder, the apparatus comprising: a polishing tool engageable with the tool holder, said polishing tool being elongated and having an axis and formed with a shank having a proximal end configured to removeably engage the tool holder and ending in a distal end to which distal end a polishing head is fixedly mounted, the polishing head being formed with defined passages through which polishing agent can flow out the polishing head; a chamber in said tool shank having a proximal end connectable to the source of pressure when said polishing tool is mounted to the tool holder, said chamber having a bore through which polishing agent can flow from a distal end of said chamber toward said polishing head; an exchangeable cartridge removably arranged in the chamber; and a displaceable piston in said chamber, said piston being located between the distal end of said chamber and the source of pressure connected to the proximal end of said polishing tool, the polishing agent, when present in said chamber, being between said piston and said bore in the distal end of said chamber, pressure from the machine tool being selectively applied to said piston to controllably move said piston axially toward said polishing head to force the polishing agent out of said chamber toward said polishing head.
