The previous process required machining of the counterbore from two sides. Additionally, chamfering had to be done manually. Overall, the process was time consuming and cumbersome.
| Workpiece | Low pressure turbine stator housing |
| Bore | Ø7 mm |
| Counterbore | with chamfer on the inner bore edge / Ø13 mm |
| Cut | partially interrupted |
| Material | Inconel 718 |
| Material thickness | 4.0 mm |
| Machine | STARRAG STC1000 |
| Estimated production volume | 50 parts (3,200 bores) / year |
HEULE proposed its SOLO counterboring tool, distinguished by its ease of use and high production reliability. Thanks to the construction of a customer-specific blade that simultaneously applies a chamfer to the bore, the previously required additional deburring process is no longer needed.
