Continuous Generating Grinding of Gears Only grinding can simultaneously deliver high surface finish and high precision geometry. Grinding is a metal cutting process that, due to innumerable cutting edges and high operating speed, can simultaneously deliver high material removal rate, superior surface finish and very precise geometry.

This occurs by means of the inser- tion of the gear into an integrated switch sliding sleeve or by applying a safety catch. The zero-clearance hold-down to accept the upper facing axial force helps with the deformation-free fixation of the gear. The lower guide stabilizes the tool axis to the clamping level at a right angle.

Gears are intentionally ground to remove unwanted material. Gear grinding is the name of a specific gear creation technique. Grinding involves the removal of unwanted materials through an abrasion process. Grinding is typically the last step in the gear creation process; other techniques have removed the majority of the material first.

The most efficient grinding method for gears is CBN generating grinding. The continu - ous contact of grinding worm and gear eliminates non-productive idle times. CBN allows cutting speeds of more than 70 m/s. They are achieved with a small tool di-ameter of 140 mm and high spindle speeds up to 12,000 rpm resulting in very short cycle times.

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 shown.
