What speed, what feed rate should be set?
If you mark the parameters of your application, a speed and a feed rate will be suggested below at the press of a button. Please note that the specified values are guide values which may need to be adapted.Return traverse always in rapid traverse.
Tip
When setting up a tool, the speed can be considerably reduced, however the feed rate per rotation is not to be decreased. Even 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 speed.

Tip for adjusting the tool
- When setting up a tool, the speed can be considerably reduced, however the feed rate per rotation is not to be decreased. Even 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 speed.
- To carry out a fast basic adjustment of the tool, it is advisable to adjust the tool to the largest dimension and then to insert it onto the pre-machined shaft by hand. The tool can then be fed in on the shaft until the rollers are felt to make contact. Starting from this dimension, 1-2 marks can still be fed in as the pretension. This basic adjustment then only requires minor corrections necessary in dependence on the roller burnishing results achieved.
Changing components
Rollers
a) Loosen clamping screw (8) and screw the mount out of the sleeve; the rollers become clear. Replace the rollers in sets and remount the components.
Taper
Unscrew the clamping screw (7) and screw the mount out of the sleeve. Unscrew the clamping screws (8). Pull the taper out of the sleeve. Note: When assembling, ensure the correct position of the "recess in the taper" and the "clamping screw".
Cage
Unscrew the clamping screw (8) and screw the mount out of the sleeve. Remove the locking ring (9) and pull off the cage toward the front.

Tip
Coat the roller seats with some grease so that the rollers are held in place by the grease during rolling.
-
Tip
When replacing the rollers, clean the cage and check it for damage, e.g. run-in marks, rough spots etc.; replace components if necessary. Worn cages or tapers can considerably reduce the service life of the rollers.

Tip
When replacing the taper, clean the cage and the rollers check them for damage, e.g. run-in marks, rough spots etc. Replace components if necessary. Worn cages or rollers can considerably reduce the service life of the taper.
Cage
Unscrew the clamping screw (8) and screw the mount out of the sleeve. Remove the locking ring (9) and pull off the cage toward the front.

Tip
When replacing the cage, clean the tool inside and grease it lightly. Dirt particles, in particular chips, reduce the tool life and the quality of the roller burnishing results.
