1. The working surface of the ceramic needle gauge should not have scratches, burrs and rust spots.

2. One or both ends of the ceramic needle gauge should be chamfered with the appropriate width and its combination angle ruler within 1mm from the surface.

3. The surface roughness R value of the ceramic needle gauge working surface is not less than 0.1um.

       Ceramic pin gauges are round bars with specific dimensions made of white steel, tool steel, ceramic, tungsten steel, bearing steel, etc. or other materials with high hardness.

　　Ceramic needle gauges are suitable for measuring hole diameter, hole spacing, and internal thread diameter in mechatronics, especially for measuring bending groove width and mold size

　　Ceramic needle gauge is used to check the position, measure the size of the hole, check the distance between the two holes, and can also be used as a pass gauge and measure the depth of the hole, which is an essential inspection tool for standardized detection of holes, and the workpiece is tested by the international advanced laser detector.
