There are many different types of thread gauges used in engineering work, and different types of gauges have different roles. Generally speaking, thread gauges can be divided into thread plug gauges and thread ring gauges, and according to their uses, they can be divided into three types: working gauges, acceptance gauges, and checking gauges.
Working thread gauges
It is a gauge used by production workers in the process of manufacturing threaded workpieces. There are two pairs of through-end and stop-end gauges.
Acceptance gauges
It is the gauge used by the inspection department or the user's representative when accepting the threaded workpiece. Generally, the acceptance gauges are not made separately, but the ones with small pitch and tooth half-angle errors are selected from the partially worn working gauges as the acceptance gauges. Acceptance gauges only have through-end acceptance gauges, no stop-end acceptance gauges.
Calibration of thread gauge
In the manufacture and inspection to detect or adjust the correctness of the size of the thread ring gauge used to gauge. For the measurement room, an inspection station to check or adjust the working gauge (card) gauge or acceptance gauge (card) gauge is more than the wear limit, which can not be used to directly test the thread workpiece.
