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.
