Abstract
For weight reducing and functional reasons, hollow shafts should be used in gear units in the near future. Inside they have a big cylindrical cavity, which is only accessible through small inlet holes. This cavity may have large diameter variations along its length. There is an undesirable scale-formation, if high temperatures occur during the manufacturing process. If there are cross bores in areas, then there are also burrs in the area of cross bore section. While this area is oil flooded, it must be free of scale and burrs. Some mechanical tools and a thermal process are able to remove the burr in cross holes. The deburring could often be done over the transverse bore. Even small cross holes can be safely trimmed. A big problem is the removal of scale in difficult to reach hollow areas. With an innovative cutting tool it would be possible to remove the scale in difficult to reach areas. Measurement methods are shown, which would be automatically check if the surface is free of scales and burrs.
