Small Indexable Slotting Cutter Made In China
Process characteristics
Overview
Compared with gear hobbing, gear shaping has its own
characteristics in terms of processing quality, productivity and
application range.
productivity
When cutting gears with large modulus, the gear shaping speed is
restricted by the inertia of the reciprocating motion of the gear
shaping cutter spindle and the rigidity of the machine tool; the
cutting process has a time loss of idle travel, so the productivity
is not as high as gear hobbing. Gear shaping is more productive
than gear hobbing only when machining gears with small modules,
multiple teeth and narrow tooth widths.
Scope of application
(1) To process gears with shoulders and double or multiple gears
with narrow empty tool grooves, only gear shaping can be used. This
is because: Shaper knives require very little space to "cut out",
whereas hob cutters interfere with large diameters.
(2) For processing herringbone gears without empty tool grooves,
only tooth shapers can be used;
(3) For processing internal gears, only tooth shapers can be used.
(4) To process worm gear, only hobbing can be used.
(5) For machining helical cylindrical gears, both are available.
But hobbing is more convenient. When inserting helical gears, the
tool spindle of the gear shaper must be provided with a helical
guide rail to provide the helical motion of the gear shaper, and a
special helical gear shaper needs to be used, so it is very
inconvenient.
