The ceramic pin gauge is a ceramic rod with a certain hardness and made of zirconia or alumina material with high hardness.

Custom non-standard ceramic needle gauges of various materials: zirconia, alumina, and various precisions can be processed. The ceramic needle gauges and plug gauges are made of yttrium-stabilized zirconia ceramics through special manufacturing and super-finishing. , JIS, NASI.
The main characteristics of ceramic pin gauges: good wear resistance, 5-10 times the amount of steel; good corrosion resistance, no special treatment is required for use and storage; good dimensional stability, because of the ultra-precision grain material Finishing, so the surface is smooth, the research force is large; the coefficient of thermal expansion is similar to that of steel; non-magnetically conductive, non-conductive, and can work in magnetic and dust environments; laser lettering on milky white surface, clearly visible and beautiful. It is an ideal substitute for commonly used metal gauge blocks.
Ceramic pin gauge application: The pin gauge is suitable for checking the position, measuring the size of the hole, checking the distance between the two holes, and can also be used as a pass and stop gauge and measuring the depth of the hole. It is an essential inspection tool for the standardized detection of holes. The laser detector detects the workpiece.
How to choose the detection position of ceramic needle gauge
The detection position of the ceramic needle gauge should be the entire working length of the needle gauge. If so, our workload is very large, so in the detection process of the diameter of the needle gauge, the following points should be noted about the selection of the detection position:
Ceramic needle gauges For handleless needle gauges, the detection position should be at least on the two ends and the middle three sections of the needle gauge, and each section should be tested at least in two radial directions perpendicular to each other.
For the needle gauge with handle, the detection position should be at least on the three sections of the head, middle and tail of the needle gauge, and each section should be detected in at least two radial directions perpendicular to each other. Because we commonly use needle gauges to detect the diameter of a hole, whether it is a handleless or a handle-type needle gauge, the size of its head will directly affect the detection result, so when testing, be sure to check the diameter of the head of the needle gauge.
