Frequently asked question (FAQ)
- Question: Will the positioning pin rust?
- Answer: Products without surface treatment will rust. It is recommended to regularly apply antirust oil for maintenance or choose products with surface treatment (no-electro nickel plated), which can prevent rust in normal atmospheric environments. No-electro nickel plated surface can effectively prevent rust.
- Question: What tools are suitable for measurement of positioning pin outer diameter?
- Answer: If the outer diameter tolerance of the positioning pin is within 0.02mm, common vernier calipers and other measuring tools with general accuracy are not suitable. It is recommended to use a high accuracy external plug gauge or an internal micrometer for measurement.
- Question: Will the outer diameter of the positioning pin become smaller after installation?
- Answer: It will become smaller, and m6 will shrink more than p6 after installation, so please pay attention during hole machining. For detailed change values, please refer to the precautions: change in inner diameter of the fixture bushing during press-fit.
- Question: What are the options for positioning pin outer diameter tolerance?
- Answer: Optional tolerances for the outer diameter of positioning pin: m6, p6, m7, g7. Basically it can meet the needs of installation and positioning under general conditions.
- Question: What fixture bushings are commonly used together with positioning pins?
- Answer: The fixture bushing is of basic shape, which is usually suitable for supporting positioning pins, checking insertion pins for fixtures, etc.
