Detailed introduction:

The pass stop caliper is a commonly used measuring tool that uses the principle of pass stop gauges to quickly measure whether the outer diameter size is qualified.

The stop end of the plug gauge is set according to the upper limit of the allowable deviation of the shaft diameter, and the through end is set according to the lower limit of the allowable deviation of the aperture. During inspection, the through end can pass, but can the stop end pass. The material used for production is GCr15, which has undergone quenching and other treatments, and has the characteristics of high hardness and wear resistance. It is widely used in precision machining to quickly measure whether the machining accuracy of the outer diameter of parts is within the qualified range.
