Internal Taper from 4mm.
Internal taper roller burnishing tool
Tool for smoothening and strain hardening of internal tapers.
Internal springs generate the required rolling force. The value of the rolling force is defined by the preload of the tool. The spring characteristics can be adapted to the requirements of the workpiece.
Advantages
- very short machining time
- both workpiece or tool can be driven
- high productivity
- fast return of investment
- easy to maintain
- compact dimensions
