Lavingia enterprise provides an automatic external track grinding machine. Its main function is grinding the track of the inner races of rolling element bearings.With an appropriate dressing device [straight, radius or diamond roller profile dresser], the machine can grind accurately the tracks of ball, cylindrical roller and even angular contact ball bearings. The whole workpiece is supported on shoe-centreless type of device having an electromagnetic chuck. The workpiece is usually supported on the track being ground. The machine is fully automatic and is controlled by a computer[pc].All grinding and dressing parameters are operator programmable. These include the rough/fine cuts, rate of feeds, dwell/sparkout times, dressing cut, etc. The high cutting velocities [wheel], peripheral speed [standard 45 m/sec, optional 60 m/sec], ensures a short work cycle and superior surface finish. The feeds controlled by stepper motors are in steps of 0.125 micron, ensuring smooth infeed. The feed slides move on pre-loaded precision linear bearings, which ensure instantaneous and precise response to the stepper motors. This results in extremely high repeat accuracies and precise geometry of the ground components.
