In the previous article, we talked about the importance of tooling and fixtures in the cemented carbide industry. In this article, let’s talk about the management of tooling and fixtures during tungsten cabide's production.
Design and Selection
The design of fixtures should closely align with the tungsten carbide's process requirements and production characteristics. During the design phase, the tungsten carbide parts' shape, size, material, and processing technology must be fully considered. Furthermore, when selecting fixtures, factors such as fixture precision, durability, and cost should be comprehensively evaluated to select the fixtures that best suit the factory's production needs.
Daily Maintenance
Regular cleaning, lubrication, and tightening of fixtures are crucial to maintaining their performance. After each day's production, operators should clean chips, oil, and other debris from the fixture surface to prevent them from entering the fixture's moving parts and affecting precision. Regularly lubricating key fixture components can extend their service life. Furthermore, loosening components such as locating pins and bolts should be tightened to ensure fixture stability during processing.
Regular Accuracy Testing and Calibration
The accuracy of fixtures gradually decreases with use. Therefore, establishing a regular accuracy testing system is crucial. Use specialized measuring instruments, such as a coordinate measuring machine, to inspect the fixture's critical dimensions and positioning accuracy. Once the accuracy deviation is found to be beyond the allowable range, calibration or maintenance should be carried out in a timely manner.
