When setting the tool diameter below the nominal size of the tool then the taper will overlap the cage. Therefore the dimension “X” (see overleaf) will increase. This increase will be about 0.2 mm per 0.01 mm diameter enlargement (one mark on the tool scale) of the tool setting.

PICCOLINO external roller burnishing tools are a particularly compact design for use on machines with limited working space, such as multi-spindle and Swiss-type lathes or rotary transfer machines.

 

 

ADVANTAGES

  • Very short machining time
  • Surface finishes of the highest quality
  • High productivity
  • Workpiece is not subjected to lateral forces
  • Both workpiece or tool can be driven
  • Fast return of investment
  • Slim design
  • Usable on all common machines
    (no special machine required)

Tip When setting up a tool, the revolution speed can be considerably reduced, however the feed rate per revolution is not to be decreased. When conducting roller burnishing under unfavorable conditions, e.g. when using high-strength materials with insufficient lubrication or very deep holes, it is advisable to reduce the revolution speed.
