Abstract
A honing device has a honing tool for the precision machining of blind-hole bores in a workpiece. The honing tool has a shank, at the free end of which honing strips are arranged. They can be moved radially outwards by means of a spreader rod. In a coolant duct system in the tool, during the machining of the workpiece coolant is supplied to the end of the honing tool facing the workpiece. To return the coolant, there are return ducts which extend along the outer periphery of the honing tool. The honing device also has a coolant feed device which can be aligned with and fixed to the honing tool. The feed and return of the coolant guarantee a precisely defined coolant circulation within the network zone.
Claims19
A honing device for the precision machining of small bores in workpieces comprising:
- (a) a honing tool including a shank having at least one work zone equipped with radially expandible abrasive covering means for machining the workpiece,
- (b) a coolant duct system formed in said tool for feeding coolant under pressure to the work zone, said system including at least one longitudinally extending groove for supplying coolant to the end face of the tool adjacent the work zone, and at least one return duct extending along the outer periphery of said tool for removing the coolant and removed metal from the work zone, and
- (c) a coolant feed device, including coolant supply means, for supplying coolant under pressure to said duct system, said device being aligned with and closely guiding said shank of said tool when coolant is supplied under pressure to said at least one groove and thus to the work zone.
