Grinding Machine, External Track

Lavingia Enterprise offers an automatic external track grinding machine. This has been developed specifically for 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 workpiece is supported on shoe-centreless type of type of device having an electromagnetic chuck. The workpiece is usually supported on the track being ground. The fully automatic machine 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.
