High-voltage conductor cable
Avoid re-clamping by back spotfacing: The customer can manufacture the entire 500-piece batch without interruption or blade change.
The customer's aim was to apply all three counterbores to the workpiece in a single clamping. The focus was on enhancing process reliability and the viability of subsequent processing.
| Workpiece | High voltage conductor cable |
| Through bore | diameter 14.2 mm |
| Back spotfacing | 30.3 mm |
| Counterbore ratio | 2.13 |
| Material | Cast aluminium AlSi7Mg |
| coolant | Internal coolant (IK) with 30 bar |
| Volume | 500 pcs/batch |
The BSF Back spotfacing tool enables machining from the front. This eliminates the time-consuming need to re-clamp the workpiece.
| Tool | BSF |
| working length | 50 mm |
| working speed | 870 rpm. |
| working feed | 0.03 mm/rev |
After approximately 1,500 cuts, the blade is still in excellent condition with minimal signs of wear. By using the BSF, the customer can process the workpiece in a single clamping. This means that the entire 500-piece batch can be processed without interruption or blade changes.
