GESAC Gear Cutting Tools Opens a New Chapter in Gear Tooth Machining

As gears are applied across various sectors of the national economy, the variety of gear‑cutting tools has continued to expand in response to changing application scenarios, and the precision requirements for these tools have also been rising. As the most widely used type of complex cutting tool in gear manufacturing, the design and manufacturing quality of gear hobs play a decisive role in the machining quality of gears.

Product Type

The newly developed carbide gear hobs include: standard involute hobs, flexible‑wheel hobs, cycloidal hobs, fixed‑mount hobs, one‑piece hobs, and worm milling cutters, among others.

Product Features

Today, we introduce a core cutting tool truly designed for high precision, high strength, and high efficiency—the carbide involute gear hobbing cutter. It is not only an upgraded choice for micro‑gear machining but also a standard tool for high‑end equipment manufacturing enterprises, featuring the following characteristics:

• Made from ultra‑fine‑grain cemented carbide bar stock, offering high hardness and excellent flexural strength. Fully ground, high‑precision tooth profile for smoother power transmission.
• Enhanced with a highly wear‑resistant coating that resists oxidation and suppresses chip buildup.
• Comprehensive coverage of small module sizes, suitable for micro‑precision gears.
• High stability, ideal for automated mass production.

Application Scenarios

Machining Case

Our involute gear hobbing cutters are used to machine the front‑end helical involute splines on motor shafts for reducers. The two‑pass machining process comprehensively improves tooth profile accuracy, tooth surface finish, and helix consistency. Compatible with mainstream shaft materials such as 42CrMo, 20CrMnTi, and chromium‑molybdenum carburized steel, the specialized coating extends tool life, reduces downtime for tool changes, significantly improves mass production yield and machining efficiency, lowers the overall manufacturing cost per unit, and reliably ensures the meshing quality of precision transmissions.

GESAC innovative R&D in gear hobbing tools goes beyond mere product iterations; it embodies our commitment to innovation‑driven development, our dedication to the field of precision machining, and our responsibility to address our customers’ production challenges. In the future, we will continue to help every user improve machining accuracy and optimize production efficiency through our meticulous tooling processes and precision‑engineered machining solutions. Together, we will deepen our expertise in precision engineering and achieve a shared future in precision manufacturing.
