One of the most interesting table-top exhibits at Mazak’s recent customer event involved a system developed with Bates Technologies (Fishers, Indiana) that allows for stroke honing on a CNC turning center. Essentially, the system consists of a special Superabrasive honing tool held stationary in the tailstock. Utilizing the W axis of the CNC lathe the tailstock strokes back and forth through a workpiece with a 4.00 inch internal diameter that is 50 inches long. A built-in gaging system monitors the ID to make sure it is honed to size. If any portion of the ID measures undersize, such as at the blind end of the bore where a full honing stroke is restricted, a signal from the gaging system causes a modification of the NC program so that it calls for the honing routine to add a dwell or short strokes to correct the bore condition automatically.

Darrell Day, the company COO, notes that using a hone on a turning center not only avoids a secondary operation, but it also makes it unnecessary to purchase and maintain a dedicated honing machine for these operations.
