Gearbox components for tractors
The customer processes eight components per re-clamping with the complete solution.
The customer was looking for a more economical solution for producing countersinks in the bores of a tractor gearbox component.
| Workpiece | Component for gearbox |
| Bore | Ø12.5 mm |
| Countersink | Ø19.0 mm |
| Depth | approx. 10.0 mm |
| Material | OSTE 460N (similar to 1.8901) |
The proposed solution is the HEULE SOLO back counterboring tool. Due to the fact that the bore is typically smaller than Ø12.5 mm (12.45), a bush is used to avoid welding. Due to clamping, there is limited space behind the bore, which must be taken into account when programming (horizontal machining).
| Tool | SOLO |
| Cutting speed | 55 m/min |
| Working feed | 0.03 mm/rev |
| Coolant | internal coolant |
The SOLO tool enables the complete machining of 8 workpieces per clamping. The tedious re-clamping and time-consuming interpolar milling of the countersink are no longer required (sinking depth approx. 10 mm). The customer now has a reliable, fast and complete solution.
