Troubles with Stop Gauge Non-compliance (Thread Enlargement) in Times of Trouble

A clear explanation of troubles related to tapping processing!

This document contains measures regarding the "stop gauge failure (enlarged internal thread) trouble." In tapping operations using holders with tension/compression on a machining center, "stop gauge failure (enlarged internal thread) trouble" may occur, but visual inspection does not reveal any chipping or welding on the tap. The cause of the trouble is believed to be due to the tap's feed being either too fast or too slow. This phenomenon is explained with diagrams and countermeasures are provided. [Contents] ■ Consultation and answers regarding stop gauge failure (enlarged internal thread) trouble ■ Explanation and countermeasures for the phenomenon of the tap's feed being too fast or too slow *For more details, please refer to the PDF document at the link below.
