Special CBN Grinding Wheels for Precision Hob Regrinding

Restoring Gear Cutting Accuracy with Advanced Grinding Technology

In the gear manufacturing industry, the quality of a finished gear depends heavily on the condition of the gear hob used during production. Over time, hobs experience wear on their cutting edges, resulting in reduced gear accuracy and productivity. Precision regrinding is essential to restore original cutting geometry and extend tool life.

Specially designed CBN (Cubic Boron Nitride) grinding wheels have become the preferred solution for hob sharpening and reconditioning due to their exceptional profile retention, grinding efficiency, and dimensional stability.

Why CBN Wheels for Hob Grinding?

CBN is the second hardest material after diamond and is ideally suited for grinding hardened steels and HSS hobs.

Key Benefits

Superior Profile Accuracy

Special wheel profiles ensure precise restoration of hob tooth geometry, helping maintain gear quality and consistency.

Excellent Surface Finish

Sharp and free-cutting CBN abrasives produce smoother cutting edges and better surface quality.

Longer Wheel Life

CBN wheels offer significantly longer life compared to conventional abrasives, reducing wheel replacement frequency.

Reduced Thermal Damage

Efficient cutting action minimizes heat generation and helps protect the metallurgical integrity of the hob.

Increased Productivity

Higher grinding efficiency reduces cycle times and improves machine utilization.
