Star SU LLC, Hoffman Estates, Illinois, has formed an alliance with Profilator GmbH & Co. KG, Wuppertal, Germany, to manufacture Scudding tools for the global market and in North America in cooperation with GMTA, Ann Arbor, Michigan. Scudding significantly improves on traditional power skiving technology for gear production, long proven in the market to be fast, accurate and versatile in use.
Often thought to be limited to internals only, Scudding is fast beginning to compete in shaping, broaching and other gear cutting applications for gears and splines.
David Goodfellow, president of Star SU LLC is very pleased with the new partnership. “Star SU is using its vast experience of gear cutting tool technology for new tool development, as well as its tool service centers to support Profilator on this new technology process. We are looking forward to working with Profilator and GMTA and see this as mutually beneficial for each company.”
Related Glossary Terms
- arbor
arbor
Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.
- broaching
broaching
Operation in which a cutter progressively enlarges a slot or hole or shapes a workpiece exterior. Low teeth start the cut, intermediate teeth remove the majority of the material and high teeth finish the task. Broaching can be a one-step operation, as opposed to milling and slotting, which require repeated passes. Typically, however, broaching also involves multiple passes.
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- shaping
shaping
Using a shaper primarily to produce flat surfaces in horizontal, vertical or angular planes. It can also include the machining of curved surfaces, helixes, serrations and special work involving odd and irregular shapes. Often used for prototype or short-run manufacturing to eliminate the need for expensive special tooling or processes.
