TAP EXTENSION WITH COOLANT DELIVERY SYSTEM |
摘要 |
A tap extension having a dual-mode coolant delivery system is disclosed which is adapted to connect a thread-cutting tap with an associated machine tool spindle having a pressurized coolant supply. The extension includes a generally elongated shank portion, with a locking arrangement provided at one end thereof for receiving and releasably retaining a tap in driven relation with the tap extension. Notably, the tap extension includes a valve arrangement whereby pressurized coolant is directed: (1) through the axial bore of a tap in a first mode of operation, or (2) exteriorly of a solid tap to between its cutting flutes in a second mode of operation. Versatile and efficient thread-forming in either blind holes or through holes is thus facilitated by use of the present construction. |
