Hobbing

Using a hob :  :
CORDM has a recent and innovative machine park with more than 50 latest-generation machines. This enables it to offer, among other things, generation hobbing operations with hobs up to module 30. All these hobbing operations can be carried out on gears up to 3.5 tonnes – Ø 1600 x 750.

Using a disc hobbing :
Up to module 40.

5-axis machines with software development:
With our 5-axis hobbing machines and software development, we can also produce a variety of bypass gears (chevrons, straight and spiral bevels, large modules 100 and over). CORDM has also extended its range to include the cutting of spiral bevel gears up to 1600 mm in diameter, module 6 to 30 up to DIN 6, using a hard cutting process known as HPG.
Your gear teeth can be removed from bevel gears, spur gears, helical gears, toothed pulleys, splined shafts and transmission elements.

Circular tools for internal and single-sided hobbing.
We can also carry out internal hobbing up to 1 tonne – Ø 2000 x 700 max. bore 1000mm and max. module 14.
We can work on single or mass-produced parts.

Hobbing: precision machining for high-performance gears

For over 40 years, CORDM has been supporting industrial manufacturers in the production of components for mechanical transmission systems, with recognized expertise in hobbing. This key operation within the production cycle demands precision, consistency, and a thorough understanding of the part’s intended function. That is exactly what we deliver : a reliable, technically sound hobbing service tailored to our clients’ needs, executed by a highly experienced team. 

Pinion hobbing is a decisive step that directly influences the performance of a mechanical assembly. At CORDM, we perform this machining operation using high-performance equipment, particularly through hobbing cutters, which allow us to achieve accurate, consistent gear profiles adapted to a wide range of mechanical constraints. Our facilities are equipped to handle a broad variety of parts : spur gears, gear wheels, internal and external gearing, helical gears, splined shafts, and more. Every component receives the same level of attention and precision, whether it’s a prototype, a short-run batch, or part of recurring production.

What sets us apart as a gear hobbing company is our ability to integrate each project into a broader, functional vision. We don’t manufacture gears simply to meet technical drawings, we produce them to operate reliably in the field, including in complex and sometimes critical environments. For us, successful pinion machining relies just as much on the quality of the process as on full control of the production chain. Our teams are continuously trained, our machines regularly updated, and our procedures are geared toward quality control and full traceability. This enables us to ensure dimensional stability, long-lasting performance, and mechanical efficiency for every gear we manufacture.

One of our specific areas of expertise is helical pinion hobbing. These gears, used in quiet and efficient transmission systems, require exceptional angular precision and an impeccable surface finish. Thanks to our experience and specialized equipment, we meet these technical demands with a high level of reliability. We also place great importance on lead times, responsiveness, and clear communication with our clients, because we know these factors matter just as much as gear accuracy.
Working with CORDM for pinion or gear hobbing means choosing a partner who understands the value of every detail. We bring our high standards, flexibility, and expertise to serve your performance needs. Every gear we produce reflects our commitment: a precise, durable component, fully integrated into your mechanical transmission system.
