How do we deliver Toughness, Guaranteed? 

OEMs that build power transmission solutions into their products need components that are designed and built to last. So we start with high-quality, US-made steel from outstanding sources. Then after using our proprietary flame machining process to cut the tooth profile, Cogmatic heat treats our gears and sprockets as a critical step the manufacturing process. When combined with carburization, steel with a native hardness of 18-20 Rockwell can be enhanced to Rc 55 to 60 at a depth of 1/8 inch. The result is an incredibly tough part with resistance to wear in the toughest environments and a long life. 

Cogmatic’s induction hardening equipment affects the entire tooth profile consistently, from root to tip. You won’t experience brittle or broken teeth with a Cogmatic gear or sprocket! Our extensive library of heat-treating patterns help us make sure we use the right time cycles and temperatures the first time. Our computer-controlled process includes an aggressive quench to obtain the depth of case hardness required by our customers. We then temper the part to reduce any residual stresses.

Induction Heat Treating

Cogmatic uses an induction heat treatment process to provide a case hardness for customer parts. This heat-treating process is localized to the entire tooth profile – roots, flanks, and tips – where case hardness is needed. Achieving the desired results depends on the part raw material, any alloy additions, the end-use application and the actual design of the part. Our operators bring a collective 90+ years of experience to this process that is both art and science!

Quenching

Within the induction process, Cogmatic will quench parts using an aggressive polymer-modified water media. The steel must be quenched rapidly to produce the desired depth of hardness. Our equipment has the capability and our personnel have the experience to provide the finished result needed.

In the process of carburizing, steel is heated in a controlled environment for extended cycles in the presence of a carbon-generating material with the effect of a change in the crystalline structure of the steel.

Tempering

The final step in the heat treatment process is to temper the part, removing residual stresses that can lead to brittle edges, resulting in chipping or cracking. Cogmatic has the ability to do this process quickly and accurately within the heat treating process – saving you time and money.

Carburizing

In the process of carburizing, steel is heated in a controlled environment for extended cycles in the presence of a carbon-generating material with the effect of a change in the crystalline structure of the steel. When combined with induction heat treating as an option, carburization yields an even tougher, more wear-resistant tooth surface. For applications where Rockwell hardness of 55-60 is required, Cogmatic adds this deep-carburization step to the manufacturing process, resulting in performance that’s unique in the world of power transmission.
