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…

Programming skills for large-scale CNC lathe processing 1. The processing sequence of the parts:(1) Drill first and then flat end (to prevent shrinkage during drilling).(2) Rough machining first, then finish machining (to ensure the accuracy of the parts).(3) Machining large tolerances first and then machining small tolerances (to ensure that the surface of small tolerance…
1. The size of the workpiece is accurate and the surface finish is poorReasons: The tool tip is damaged and not sharp; the machine tool resonates and the placement is not stable; the machine tool has a creeping phenomenon; the processing technology is not good.Solution: After the tool is worn or damaged, it is not…

To put it simply, both vertical machining centers and carving and milling machines are essentially milling-type CNC machining machines. They are completely different from each other in terms of processing capability and usage. Vertical machining centers are equipped with tool magazines and automatic tool changers, making them capable of not only milling, but also drilling,…
