A Spanish manufacturer of cylinder heads for passenger car engines asked Sandvik Coromant for help. The machining process was unstable and they had problems with burr. Another problem was the unpredictable insert tool-life, which depended on the cartridge adjustments that differed slightly from set-up to set-up.
Provide a stable and burr-free machining process with predictable insert tool-life.
Rougness (R): 4 (Rmax: 20)
Waviness (W): 4
The Sandvik Coromant M5B90 offers a smooth finishing operation with predictable wear and no burr. As the cutter provides thin chips, they are easily removed from the component to avoid damaging of the face in the subsequent operation.
With an optimized number of inserts that are always correctly positioned on the cutter, the customer can speed up the cutting data and save money on both a limited number of inserts and reduced cycle time.
