                               Method of thread machining
1, Thread cutting generally refers to the method of machining threads on the workpiece with

forming tools or abrasives, mainly including turning, milling, tapping, threading, grinding, grinding

and cyclone cutting.

When turning, milling and grinding threads, the transmission chain of the machine tool ensures that

the turning tool, milling cutter or grinding wheel moves a lead accurately and evenly along the axial

direction of the workpiece. During tapping or threading, the tool (tap or die) rotates relative to the

workpiece, and the first formed thread groove guides the tool (or workpiece) to move axially.

2, Thread turning turning threads on a lathe can be turned with a forming turning tool or a thread

comb tool.
Turning thread with forming turning tool is a common method for single piece and small batch

production of threaded workpiece because of its simple structure; Turning thread with thread comb

cutter has high production efficiency, but the tool structure is complex. It is only suitable for medium

and large-scale production of short thread workpieces with fine teeth. The pitch accuracy of turning

trapezoidal thread by ordinary lathe can only reach grade 8 ~ 9 (jb2886-81, the same below); Machining

threads on a specialized thread lathe can significantly improve productivity or accuracy.

3, Thread milling milling is carried out on a thread milling machine with a disc milling cutter or a comb

milling cutter.
Disc milling cutter is mainly used for milling trapezoidal external threads on workpieces such as screw

rod and worm. Comb milling cutter is used for milling internal and external ordinary threads and conical

threads. Because it is milled with multi edge milling cutter and the length of its working part is greater

than the length of the processed thread, the workpiece can be processed only by rotating 1.25 ~ 1.5

revolutions, and the productivity is very high. The pitch accuracy of thread milling can generally reach

grade 8 ~ 9, and the surface roughness is R5 ~ 0.63 microns. This method is suitable for mass

production of threaded workpieces with general accuracy or rough machining before grinding.
