With the development of CNC machine tools in China, thread milling as a method of using CNC machine tools to process threads has gradually been accepted and loved by the majority of customers in China. Thread milling is accomplished by using the three-axis linkage function of NC machining center machine tool. The thread milling process…
CNC horizontal lathe in the process of processing, the surface of the workpiece may have a processing mark, this uniform mark is normal, but also the basis for the finish of the processing surface. But sometimes there will be another trace, that is, the linear cut into a ripple, can be formed on the cylindrical…

In order to improve the efficiency of NC lathe, in the actual production application, we must first understand it. The material, structural characteristics and tolerance requirements of the parts machined by NC lathe are found out by real analysis. Roughness, heat treatment and other technical conditions. Then according to the analysis results, choose a reasonable…
