tungsten steel processing precision tungsten steel probe stylus IAC tungsten steel stylus, PTJ tungsten steel production custom provides tungsten steel probe, tungsten steel stylus, tungsten steel stylus, tungsten steel insert pin and other precision tungsten steel measuring parts.
The stylus of the probe used in the precision measuring instrument requires high precision and long-lasting stability to ensure the accuracy of the measurement data. Precision measurement testing is mainly used in measurement quality inspection institutions, national defense and military industry, automobiles, aerospace, metallurgy, machinery, electric power, chemical industries and other industries.
Tungsten steel material has good physical properties, high hardness, long-lasting use and no deformation. The precision measurement test instrument selects tungsten steel probe, tungsten steel rod, and tungsten steel stylus as the measuring point parts for the measurement test, which is a relatively high-quality application. PTJ Tungsten Steel Processing provides customized IAC tungsten steel styli for Shanghai dedicated to precision measurement and testing equipment manufacturing enterprises.
The IAC tungsten steel stylus is completed by the combined processing form of tungsten steel probe + tungsten steel stylus. There are many specifications, sizes and models. A simple list of several tungsten steel stylus specifications:
1. IAC2.2 tungsten steel stylus: Φ0.6*2.2*R0.025*45°*Φ1*Φ2*37.75, the tungsten steel probe size is Φ0.6*2.2mm, and both ends of the tungsten steel probe are processed The arc of R0.025, the angle is 45°, the center is punched and assembled on the tungsten steel measuring rod of Φ1*14*Φ2*37.75.
2, IAC-T80.2 tungsten steel stylus: Φ1.2*8*R0.025*22.50°*Φ2*37.75, the tungsten steel probe size is Φ1.2*8.0mm, and both ends of the tungsten steel probe are processed The arc of R0.025, the angle is 22.50°, the center is punched and assembled on the tungsten steel measuring rod of Φ2*37.75.
This series of tungsten steel probes + tungsten steel probes are assembled in the middle of the tungsten steel probe specifications and models, mainly due to the size change of the tungsten steel probes and the combined processing of the tungsten steel probes. The R arc is required to be accurate, and the size and position of the tungsten steel probe perforated tungsten steel rod are consistent up and down.
The physical properties of the PTJ tungsten steel processing precision tungsten steel probe stylus IAC tungsten steel stylus meet the requirements of the national standard. The physical parameters of commonly used tungsten steel materials are as follows:
1. Co content: 6%-20%.
2. Density g/cm3: 13.85～14.54.
3. Hardness: 87-92.0HRA.
4. Grain size: 0.6-1.6um.
5. Bending strength: 3200-4000MPa.
6. Elastic modulus GPa: 460-580.
7. Thermal expansion coefficient 10-6/℃: 4.9-5.4.
