About this site

of grinding times, twist control grinding is on par with the standard continuous generating grinding which is well-established in the industry. High volume TCG production of twist-free gears, or gears with a defined twist, is now standard production practice at several automotive gearbox manufacturers.

About this site

Twist Control Grinding TCG means that the forces acting on the bearing surfaces can be ideally distributed, resulting in higher power density and increased longevity of gears. Higher power density, for example, translates into smaller gears, and by extension, into a weight reduction of the transmission itself, which contributes to better fuel ...

About this site

Apr 01, 2005 · Size reduction, in general, and grinding in particular is an energy intensive operation. The product fineness from grinding circuits affects the performance of the subsequent separation processes. Hence, a close control of grinding circuits is extremely important in order to save energy losses and to improve the efficiency of downstream processing.
