cutting super-finishing machine / drag / for tool

Nagel TF4 tape finishers are used to primarily finish journals, faces and tapered surfaces. Parts commonly finished with the technology includes, Crankshafts, Balance Shafts, Cam Shafts, Transmission Shafts, etc.
Aluminum Oxide, Sillicon Carbide and Diamond abrasives glued on a Mylar backed film serves as the cutting tool. Tapes are available in various grit sizes - from 1 um for ultra fine finishes up to 120 um for aggressive stock removal.
Tape is indexed at the beginning every finishing cycle. Hence each part sees a new cutting tool. This keeps the surface finish variation to a minimum and permits use of water soluble synthetic coolants as loading is not a concern.
