What is a needle gauge?
Necessary inspection tool for needle gauge to measure precision holes
Needle gauges, also known as plug gauges, bolt gauges, pin gauges, cylindrical gauges, PIN gauges and PIN GAUGE, etc., are gauges designed to check whether products meet standards. They are made of stainless steel, tool steel, ceramics, tungsten steel, and bearing steel. A round rod with a specific size made of high hardness and other materials. It is used to check the position, measure the size of the hole, check the distance between two holes, and can also be used as a stop gauge and measure the depth of the hole. It is a necessary inspection tool for standardized inspection of holes.
The precision specifications of the needle gauge are as shown in (below):
The outer diameter of the needle gauge size ranges from φ0.200 to φ50.00m, and the standard product is below φ20mm, and can be produced to three decimal places. 0.2mm~10.00mm, the accuracy of the general standard pin gauge is ±0.5um, and the accuracy of the ultra-precision type is ±0.3um (applicable to high-precision industries such as optical fiber).
Types and classification of needle gauges
EISEN needle gauge materials are divided into three categories
- Bearing steel
- Ceramics
- Super hard (tungsten steel)
| Needle gauge introduction | Steel standard product | Ceramic standards | Super hard standard |
|---|---|---|---|
| Material |
φ0.05~φ1.499mm SKH-51 tool steel φ1.50mm~SUJ-2 bearing steel (high carbon steel) |
φ0.2~20.00mm ceramic |
φ0.10~φ0.30mm ultra-fine super-hard alloy φ0.30~ V-20mm tungsten steel |
| Abrasion resistance | general | good | excellent |
| Rustiness | general | excellent | good |
| Temperature effect | general | good | excellent |
