Advantages:
- Processing cylindrical shafts also against shoulder
- Processing tapers up to 5°
Modular Single Roller Outer Diameter Burnishing Tools for External Use
| Application | cylindrical shafts also against shoulder, plane surfaces |
|---|---|
| Diameter range | from 15mm, due to the rolling forces during the process, the stability of the workpiece and the clamping has to be ensured (e.g. by using tail-stock or rest) |
| Rolling unit (4 rollers) | with 4 small rollers (one roll in process), – lower rolling forces, quick and easy change of the rollers by rotating the cage in steps of 90° without removing the tool out of the machine |
| Rolling unit (1 roller) | with 1 bigger roll, – higher processing speed, and higher lifetime |
Application parameters:
Please note that this information represents standard values which must be adapted to the individual cases.
| Speed | up to 200 m/min |
|---|---|
| Feed rate | 0.05 – 0.3 mm/rev |
| Workpiece allowance | up to 0.03 mm |
| Tool pre-load | up to 1.5 mm |
| Lubrication | emulsion or oil; filtration of the lubricant (< 40 μm) can improve the surface quality and the tool life |
| Pre-machining of workpiece | surface roughness up to 15 μm |
| Workpiece hardness | up to 45HRC |
