FinishMeister- Piston- AH725
IMPROVED PRODUCTIVITY
In turn-milling of the outer periphery of pistons, two end mills were previously used for roughing and finishing. With FinishMeister, tool consolidation was achieved, and roughing efficiency became three times higher than before. Tool life remained equivalent to conventional tools, allowing for trouble-free operation and adoption on the mass production line.
