Our customer manufactures engines used in motorsports.
The company was looking for a cost-effective solution for the application of counterbores.
We have recommended our efficient HEULE BSF Back spot facing tool.
For this counterbore a customized BSF tool with a special working length of 80 mm has been designed.
Speed 2000 rpm, Cutting speed vc 140 m/min.
Feed 0.05 mm/rev.
To operate the BSF tool an internal coolant with 20 bar pressure minimum is required.
By using the HEULE back spot facing tool the workpiece can be machined fully in one setup without reclamping or additional process step.
The customer is very satisfied by the result and the achieved time savings. The high spindle speed reduces the fluttering of the blade due to the interrupted cut considerably.
