What are the characteristics of spiral groove milling in precision
parts processing
In precision parts processing, the spiral grooves machined by
milling machines are usually spiral grooves formed by Archimedes
lines, which can be divided into plane spiral grooves and
cylindrical spiral grooves. The machining of the plane spiral
groove is similar to the machining of the straight forming surface
of the disc cam. The processing of cylindrical spiral groove has
the following technological characteristics:
(1) Generally, the universal indexing head is configured with an
exchange gear for processing. The exchange gear is configured with
two methods: indexing head side shaft configuration and spindle
configuration to adapt to different lead needs.
(2) Disk milling cutter or finger milling cutter can be used for
milling cylindrical spiral groove. When milling, if disk milling
cutter is used, an included angle shall be formed between the
milling cutter and the workpiece axis. The angle turned shall be
calculated according to the helix angle. The angle rotation is
generally realized by the workbench or end milling head.
(3) Interference phenomenon exists in the milling of cylindrical
spiral groove. milling interference is caused by the change of
helix angle of different diameters and the curvature radius of disc
milling cutter. interference will affect the groove shape of spiral
groove.
(4) When using special milling cutter to mill spiral groove in
precision parts processing, such as spiral groove of fried dough
twist drill, it must be adjusted according to the designed tool
setting parameters to meet the processing requirements of the
design parameters.
