The roughing-finishing process refers to a two-stage machining strategy:
- Roughing: Coarse material removal to bring the workpiece quickly close to its final shape. Productivity is prioritized over surface quality.
- Finishing: Fine machining of the surface to achieve precise dimensions and high surface quality.
Depending on the tool type and cutting geometry, the roughing-finishing process can also be performed using a single URMA spindle tool.
Presetting of roughing and finishing cutting edge
Simultaneous single-pass roughing and finishing requires radial and axial boring head offset. Cutting time is dramatically reduced.
On both systems IntraMax and MegaMax/ SuperMegaMax RFP can be applied and covers the entire diameter range from 49 to 2'400 mm. Recommended cutting depth on the roughing insert is ap 2,5 mm for steel.
Further advantages:
- reduced tooling investment
- shorter cutting time
- high surface qualtity
- IT7 tolerances in one pass
