Appearance of grinding burn in gear pro-file grinding. Typically, grinding burn appears only locally along the tooth profile in gear profile grinding. This is due to either the chosen process strategy or heat distortions and centering defaults. In this article, two examples of local grinding burn—dependent upon the process strategy— will be ...

The process involves the part being supported on a workpiece rest blade that sits between two rotating cylinders: A regulating wheel, which controls the part's rotational speed and feed rate (for in-feed grinding) or linear travel (for through-feed grinding) A …
Grinding produces a high quality surface finish, correcting any distortion following heat treating, establishes profile dimensional accuracy. In some cases, grinding can be utilized to grind gears from solid eliminating the hobbing process. Main Gear GrindinG MeThOds continuous gear generation Profiles an exact gear form into the workpiece.
Weld grinding is the removal of excess stock from the weld itself- a process that often results in ergonomic strain on the worker, slower production as well as grinding results that vary. To resolve these issues in the manufacturing industry, Lincoln Electric has teamed up with the abrasive expert 3M in the release of the new Fab-Pak® OmniClean™ Grinding Cell!
