Introduction

The tooth of hob is a gear machining tool in which the cutter teeth are spirally arranged along a cylinder or a cone for machining cylindrical gears, worm gears and other cylindrical toothed workpieces. Depending on the application, the hob is divided into a gear hob, a worm hob, a non-involute roll hob and a set hob.

Application Area

Suitable for kinds of engineering rigs, such as coal mines, water conservancy, bridges, and building foundations.

Technical Introduction

1. The hob ball for the hob is produced from high-purity raw materials with a more than 99.95% tungsten content.

2. It is pressed by isostatic pressing precision press and over-pressure sintering to make the product denser and the wear resistance is increased by 24% compared with the same industry products.

3. Different formulas are adopted for different rock formations, and the spherical teeth are proportional to the service life of the pants.
