Mar 20, 2018· With discontinuous profile grinding, the tooth flanks of a gear can be either ground separately or joint depending on the number and set-up of the grinding wheels, Fig. 4 (Abler et al. 2004). Fig. 4 Discontinuous profile grinding tools and set-up. (Reprinted from Karpuschewski et al. 2008 with permission from Elsevier)
Profile grinding Discontinuous generative or profile grinding is characterised by the fact that complete tooth spaces, or in the case of older machines just the flanks of the teeth, are ground by means of shaped wheels that are chamfered on both sides.
5 Surface Damage Caused by Gear Profile Grinding and its Effects on Flank Load Carrying Capacity (September/October 2004) Instances of damage to discontinuous form ground and surface-hardened gears, especially of large scale, have recently increased.
For the hard finishing of milling cutters and other cutting tools, flute grinding is used first followed by face and circumferential machining. Machining of the flutes involves coupled translational and rotational movements and is also similar to the discontinuous profile grinding of gear teeth.
The grinding principle using the discontinuous profile method is rather straightforward: the shape of the wheel must mirror that of the gear profile to be ground. For obvious reasons the wheel must be dressed a few times per workpiece rather than getting several gears per dressing operation, as in the continuous generation process.
Most of the following solutions combine continuous generating grinding and discontinuous profile grinding in one machine. For the grinding of your gears, shafts, rotors and special profiles KAPP NILES offers best suitable profile grinding machine and generating gear grinding machine.
The development of discontinuous profile grinding allowed the complete left flank and right flank profiles to be finished at the same time and has significantly improved the cycle times of grinding. The machine technology is constantly advancing to provide gear manufacturers
