  CENTRELESS THROUGHFEED SUPERFINISHING  MACHINE MODEL – ARISUP 300TF

Product Description

Operation:


The components are continuously fed from one end of a pair of hyperbolic rollers and finished products are collected at the other end. Pneumatic oscillation system gives 1600 - 1800 strokes per minute to the superfinishing heads having rough to finish stones. These stones are pressed against the rotating components with the help of pneumatic cylinders. During superfinishing operation, the components rotate; the superfinishing stones oscillate parallel to the axis of the components at a very high frequency generated by pneumatic power unit.

By regular flushing action with the help of coolant high degree of surface finish as fine as 0.02 micron Ra can be achieved. This also improves roundness and bearing contact area eliminating chatter marks, feed spirals resulted during previous operation.

Special Features:

The machines are also available with various special features like

  • Automatic feeder
  • Taper roller superfinishing
  • Automatic magnetic separator with paper band filter.
