Affolter Technologies SA from Malleray-Switzerland produces Gear Hobbing Machines for small pitch gears.
Affolter has developed a new option called „µ-Skiving“, which allows to apply a technique of skive hobbing on smallest gears. Pre-hobbed and hardened gear blanks are positioned and finished using a special hob. The cutting process is called skiving. This process is a finishing operation and provides an alternative to gear grinding in hardened materials for modules of 0.1 to 1.0 mm (DP 254 to 25.4). In order to allow the hob cutter to synchronize with the pre-hobbed gear, each workpiece has to be measured and positioned automatically on the machine. This is applied for the first time on modules under 0.5 with a highly accurate measuring system. The precision of this system allows a repeatability of just a few microns and is very fast: the measuring process takes just about 1 second.
