Precision cemented carbide threading tap |
摘要 |
A precision cemented carbide threading tap is designed for use in precision tool holders in synchronous high speed tapping. The precision tap includes a fully cylindrical shank without the aid of squares, flats or other notches. The precision tap further includes a threaded body portion and a threaded cutting chamfer portion. The threaded body portion and the threaded cutting chamfer portion of the precision tap are concentric to the cylindrical shank of the tap within a runout of 10 microns. The precision cemented carbide threading tap improves the accuracy, life and speed by which internal screw threads are produced.
