Thread processing method of processing center

Thread processing is one of the very important applications in the processing center, drill edm processing quality and efficiency of the thread will directly affect the production efficiency of the machining quality and machining centers. Processing center performance improvement and the improvement of the cutting tool, the thread processing method is also continuous improvement, is also a gradual increase of the accuracy and efficiency of the thread processing.

In order to process thread processing methods in the processing of a reasonable choice, improve production efficiency, to avoid the quality of the accident, now in several commonly used in the actual thread processing method are summarized as follows:
 

Classification and characteristics of the tap processing

Tap processing thread hole is the most common processing methods, it is mainly applied to the smaller diameter (D <30), the threaded holes of the hole location accuracy is not required. In the 1980s, the threaded holes are used flexible tapping method, flexible tapping chuck clamping tap, tapping chuck can do axial compensation, compensation for machine tool axial feed and spindle speed is not synchronized into to error, to ensure the correct pitch. Flexible tapping chuck structural complexity, high cost, easy to damage, less efficient processing. In recent years, the performance of the machining center to improve gradually, rigid tapping into the basic configuration of the machining center. Therefore, rigid tapping to become the main method of the thread processing.

Rigid collet chuck clamping tap spindle feed and spindle speed control by the machine is consistent. Collet chuck for flexible tapping chuck structure is simple, cheap, widely used, in addition to clamping tap, but also gripping end mills, drill bits and other tools, can reduce the cost of the tool. At the same time, rigid tapping, high-speed cutting, and processing center efficiency, reduce manufacturing costs.
