High Quality Gear Shaving Cutter Made In Zhuzhou, China
What is Gear Shaving Cutter ?
There are many narrow grooves forming cutting edges on the tooth
surface, and the gear-shaped gear processing tool is used to
process the workpiece according to the principle of helical gear
meshing. During processing, the cutter cuts off whisker-like fine
chips from the tooth surface of the gear, so it is called a shaving
cutter. The shaving cutter is used to finish the gear teeth after
hobbing and shaping (see gear machining). Commonly used disc
shaving cutters are like a hardened helical cylindrical gear (Fig.
1), and the grooves on the tooth surface have two forms: one is a
circular or helical through-hole on the entire ring gear. Slot, the
cross section of the slot can be rectangular or trapezoidal. This
shaving cutter only sharpens the front (slot) after being blunt,
and the tooth shape and outer diameter do not change. Since the
through slot cannot be made too deep, only the It is suitable for
shaving knives with a module less than 1.75 mm; the other is that
the grooves on both sides are blocked, and they are inserted with a
comb-shaped blade. Drill slanted holes. This kind of razor needs to
be reground tooth shape and tooth top cylindrical surface after
blunt use.
In order to reduce the cutting load of each tooth, the number of
teeth of the shaving cutter is large, and the prime number is
generally taken to avoid a common factor with the number of teeth
of the gear being cut, otherwise the error of the shaving cutter
will be copied to the gear to be processed. According to the
international standard, the precision of the razor has three types:
AA, A and B. In actual production, the gear tooth profile shaved
with the correct involute tooth profile shaving cutter often
deviates from the correct involute near the pitch circle of the
gear, concave inward, and the deviation is about 0.01~0.03 mm. The
tooth profile deviation of spur gears is larger than that of
helical gears. In order to make the workpiece get the correct
involute tooth shape, the tooth shape of the shaving cutter should
be corrected. In mass production, the tooth shape correction curve
of the shaving cutter is determined by experimental methods.
The shaving cutter can process the inner and outer cylindrical
gears of straight and helical teeth, with high production
efficiency and smooth surface. In addition, there are worm gear
shaving cutters for machining precision worm gears. The type and
parameters of the basic worm should be the same as the working worm
that matches the worm gear. Like gear shaving cutters, it has many
narrow grooves on the helical surface to form cutting edges and
accommodate chips. Worm gear shaving cutters are difficult to
manufacture and are only used when machining worm gears that
require high precision.
