Gage for measuring the intensity of shot-blast peening

摘要

An Almen type gage with an improved test strip support mechanism, which concentrates the holding force at the contact points. The support mechanism includes four paired contact balls and a permanent magnet engaged between the paired balls to magnetically hold the test strip against the contact balls. Each contact ball seated atop a set screw turned into a test platform with the magnetic flux of the permanent magnets passing through both the contact balls and the set screws.
