These ceramic pin needle gauges are made of zirconia (zirconium oxide, ZrO2) ceramic material, with precision machining, they are used for precision measurement.
The zirconia ceramic pin needle gauges have linear expansion property close to steel, and due to the high density and high hardness of zirconia ceramic, they are not easily broken or chipped. For the possible need for heat resistance, we are able to put handles on them.
Ceramic plug gauge can be used individually or combined with other detection instruments together, needle gauge using zirconia material itself has the characteristics of high hardness, high wear resistance, surface hardness is not lower than HRC90 degrees, second only to diamond, no deformation, precision is very high.Ceramic needle gauge service life is 5-10 times of steel, has a strong corrosion resistance, in the use of no special protection and less maintenance, can be used for a long time of precision measurement.The needle gauge is subjected to ultra-precision surface treatment to ensure stability and is minimally affected by temperature coefficient.
Usage: it is suitable for measuring hole size, checking hole distance and measuring hole depth in mechanical and electronic industry. It can be used as stop-gauge. It is a necessary inspection tool for hole standardization inspection.
We are a professional manufacturer of ceramic pin needle gauge, also custom manufacturing different specifications of ceramic parts, according to the parameters or drawings provided by the customer.
