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, are manufactured at DVS TOOLING using the specially developed “DVS LaserCut” finishing method. This method produces 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 during the dressing process and thus finally to the workpiece. This optimises the reproducibility and surface quality of tooth flanks again, as well as further reducing the noise level of the machined parts in the gearbox.
Compared with a dressing process using conventional diamond dressing gear wheels, the new VSD technology produces stable profile shapes and precision never achieved before.
