Technical details: Rolling unit for external use
Modular single-roller burnishing tool 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 tailstock or rest)|
|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|
|with 1 bigger roll, – higher processing speed, and higher lifetime|
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 45 HRC|
