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.

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.

DTR newly developed carbide hobs can cut gears down powerfully at high speed which brings higher efficiency of production than conventional HSS hobbing. Advantages 1) 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. Specification module : m0.5~m3.0 accuracy class : DIN3968 , class A / AA / AAA Disadvantages 1) 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.

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. HOB & BROACH Special Broaches 516 Upon special request, makes it possible to do very complicated machining.
