A worm hob is designed based on the worm shaft specification. There are no standards for worm gear hobs.
Generally this hob is manufactured as ‘ZK’ type. Since the overall dimensions of the hob are determined by the worm shaft and worm
wheel data, please specify the following data when ordering:
1. Normal or axial module, DP
2. Out dia or pitch dia of worm
3. Worm lead angle
4. Number of threads and hand of thread
5. In case of shank type, shank standard
6. Contact ratio (Non-Standard): Standard contact ratio is generally
20~30%, and users can select either hole or shank type.
VEX WORM - It’s different based on the tooth maker. Please discuss
when you order.
sometimes it’s impossible to produce with an Arbor Type Hob.
When ordering a combination worm hob and arbor, please provide the
arbor specification, taper of the hobbing machine, setting bolt standard
and hob rotating direction.
In addition specify whether the contact of the arbor is right or left.

The teeth and body are assembled separately and with different
materials.
Advantages1) The cutting condition is efficient controlled relief angle.
2) Cost effective with lower material price for body.
3) Useful for high speed cutting with controlled arbor.
Disadvantages1) The manufacturing process is complex.
2) The out-diameter of built-up hob increases more than that of a
standard gear hob.
3) It requires more flexible delivery terms than a standard gear
hob.
DTR newly developed carbide hobs can cut gears down powerfully
at high speed which brings higher efficiency of production than
conventional HSS hobbing.

The Master gear is used for checking the precision of the gear,especially in the automobile and aerospace industries. It features
high precision, long tool life, and excellent efficiency. When the
master gear engages with the gear on the rolling fixtures, the
value of tooth is inspected by a variety of indicators, chart or
other indicating devices, etc.

Round Broaches
These broaches perform precise broaching operations and do not require
any pre-machining as in the case of other broaches.
Two kinds of round broaches are available, one for broaching only and
the other with part burning.
Polygonal Broaches
These broaches perform precise and simple polygon profiles made by
casting or forming.
Many kinds of polygon broaches are available such as square, rectangular,
hexagonal or other polygon profiles.
Spline Broaches
An involute spline is generally used vs. a parallel side spline, as it transmits
more power and rotates more smoothly.
To enhance a concentric degree, spline broaches with round teeth are also
produced.
Serration Broaches
These broaches are generally used to cut a shaft and hole that is semi
permanent. New models and involute serration broaches are available.
Special Broaches
Upon special request, makes it possible to do very complicated machining.
