How to deal with the steering movement and guide wheel heating of wire cutting machine tools in electric discharge? Usually, in our use, wire cutting machine tools have problems such as steering movement, guide wheel heating, and large radial runout. How should we deal with these problems? Below, we will provide a detailed analysis of this problem:
The cause of the problem is that the guide wheel is a crucial component in the wire cutting system. Due to the lack of strict control of the guide wheel during the device process, or the poor flatness and straightness of the bearing sleeve, or the unqualified quality of the purchased bearing, the guide wheel generates heat during operation, affecting its service life. The shaft steering and radial runout are relatively large, causing molybdenum wire vibration, which will start to affect the accuracy of wire cutting components.
① Ensuring the manufacturing accuracy of the guide wheel, controlling the steering and radial runout of the guide wheel, is beneficial for reducing the oscillation of molybdenum wire and improving the stability of the machining process;
② Ensure the accuracy of the guide wheel device, ensure that the rolling of the guide wheel is sensitive, and prevent the guide wheel from jumping and swinging;
③ Ensure the quality of the bearings of the wire cutting machine tool in electric discharge, use waterproof guide wheels to effectively improve the service life of the bearings;
