Shell ring connector
Drilling, forward and backward chamfering simultaneously: Cost reduction of more than USD 100,000 per year.
The shell ring connector of an 8-speed gearbox has 12 bores with Ø5.0 mm per workpiece.
| Workpiece | Shell ring connector |
| Bore | Ø5.0 mm |
| Material thickness | 4.0 mm |
| Material | ADC 10 |
| Machine | Magnix tapping centre |
| Volume | 1 million workpieces per year |
HEULE recommended its combined drilling and chamfering tool VEX 5.0 (GH-QO-4000) with SNAP technology. The bore is first drilled, followed by the chamfering of the front and back bore edges.
| Tool | VEX |
| Drilling speed | 100 m/min |
| Drilling working feed | 0.2 mm/rev |
| Chamfering speed | 72 m/min |
| Chamfer working feed | 0.15 mm/rev |
| Coolant | external coolant |
This solution offers significant processing time savings by combining three process steps in a single pass. With the switch to VEX, the gearbox manufacturer eliminated two CNC machining centres and reduced its annual expenses by more than USD 100,000.
