Abstract: The application describes a honing tool for use with a CNC machine. A fluid actuator provides the mechanism for causing radial adjustment of abrasive elements. The actuator consists of a piston and cylinder assembly mounted within the tool and powered by cooling fluid of the CNC machine. Actuation motion is driven by a helical drive on the piston which imparts rotary motion to a feed rod. Upper and lower feed rod sections are connected through a clutch. Axial movement is imparted to a feed cone by threaded engagement between the feed cone and the lower feed rod section.

Abstract: A detachable tool body is connected to the mandrel by means of a universal type coupling. The mating end of the drive shaft is constructed with U-shaped element having a pair of arms extending axially towards the tool body. The inner surfaces of the arms form a partially cylindrical seat. A similar U-shaped element having a pair of similar arms is constructed on the tool body with basically a mirror image profile relative to the drive shaft element. In the assembled position the mated arms define an inner bearing chamber (seat) having dual cylindrical surfaces with transverse axes. A barrel is constructed, which is shaped to nest in the seat formed by the mated pair of U-shaped elements and acts as a bearing which allows dual axes of motion. The adjustment rod of the abrasive element adjustment mechanism extends from the drive shaft through a bore in the barrel and into the tool body.
