Vario Speed Dresser

The latest generation of PRÄWEMA SynchroFine® gear honing machines uses the so-called VSD technology for dressing the honing tools. “VSD” stands for VarioSpeedDressing® and describes a dressing process with a geometrically defined cutting edge in which only the leading cutter of the dressing tool enters the honing ring. Compared to conventional dressing with diamond dressing gears, VSD dressing tools achieves previously unattainable profile shapes and accuracies.

VSD dressers, also known as VarioSpeedDressers®, are manufactured at DVS TOOLING using the specially developed “DVS LaserCut” finishing process. This process creates a homogeneous structure of the cutting edge surface on the dresser. The result is an extremely high surface quality, which is transferred to the honing ring and ultimately to the workpiece during the dressing process. As a result, the reproducibility and surface quality of tooth flanks is further optimized and the noise level of the machined parts in the gearbox is further reduced.
