7种螺纹加工方法
1、 Cutting method
Cutting method is currently one of the most widely used thread machining methods. This method can use cutting tools such as turning tools, cutting cutters, and milling cutters for machining. The cutting method is simple to operate, but requires precise machining equipment and low machining efficiency. In addition, due to the slow relative movement speed of the cutting tool, it may cause the problem of rough machining surface.
2、 Etching method
Etching method is a chemical processing method, which has the advantage of being able to process very small and complex thread shapes. The etching method requires the use of chemicals such as acids and bases for processing, and requires hazardous material management and strict operating procedures. In addition, the etching method also requires the processing of molds, so the cost is relatively high.
3、 Rolling method
Rolling method is a processing method that uses rollers to press the workpiece and convert its shape. Rolling can process the surface of a workpiece into parallel and continuous external and internal threads. Compared to the cutting method, the rolling method has the advantages of high machining efficiency, good surface quality, and high material utilization of workpieces, especially suitable for large-scale thread processing.
4、 Line cutting method
The wire cutting method is a method of using high current discharge to process the spiral shape on the electrode along the workpiece. This processing method can produce very small spiral lines, with high processing accuracy and good surface quality. However, the processing speed of wire cutting method is relatively slow, and it also requires periodic maintenance and upkeep of the processing equipment.
