Modular single-roller burnishing tool system
Rolling unit for smoothening and work hardening holes.
Technical details: Rolling unit for internal use
Modular single-roller burnishing tool for internal use
| Application | through and blind holes |
| Diameter range | from 32 mm, due to the rolling forces during the process, the stability of the workpiece and the clamping has to be ensured (e.g. by using rest) |
Advantages
- processing of cylindrical holes
- processing tapers up to 5°
Application parameters
Please note that this information represents standard values which must be adapted to the individual cases.
| Speed | up to 130 m/min |
| Feed rate | 0.05 — 0.3 mm/rev |
| Workpiece allowance | up to 0.03 mm |
| Tool pre-load | up to 1 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 45 HRC |
