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, it is advisable to reduce the revolution speed.
When setting the tool diameter above 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.
Further information on speed and feed rate can be found under www.baublies.com.
One mark on the tool scale 0.01 mm.

The graph below shows the revolution speed and the feed rate for the whole diameter range of the IRG-3-S.
For your specific application we recommend to use our interactive calculator for machining parameters.
Please remember that these results are only guide values. Different machining conditions (e.g. pre-machining, material, lubrication…) may require different machining parameters.
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.
