Inspection Tools for Machining

　　In the machining industry, the precision of the workpiece is very important.So in production, we need to use a lot of measuring tools.Do you know what the commonly used measuring tools are?

　　Commonly used measuring tool has ordinary caliper, micrometer (inside diameter, outside diameter), height gauge, average depth gauge, depth micrometer, digital display caliper, dial indicator caliper, feeler, tooth thickness common normal inside and outside micrometer, thread gauge, r-gage, dial indicator, dial gauge, gauge block gauge block, the roughness of the same block, height gauge, projector, three coordinates, and so on.
