This turbine manufacturer was looking for a cost-efficient, yet reliable, solution for the application of back spotfacings without the need to turn the turbine housing in the machine.
| Workpiece | Aviation component |
| Material | M-152 |
| Parts per year | 150 parts (9`600 bores) |
HEULE introduced the BSF back spotfacing tool which allowed the machining of large counter bores in one operation with a very high reliability and quality. Turning and re-clamping of the housing was eliminated.
