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.
