Metal sheet die

This metal sheet die with carbide core was machined on a Mikroturn® 100 with a 3-jaw chuck in a single set-up. The goal was to replace the current grinding operation wth a faster process. With hard turning you can machine this die in < 10 min., whereas grinding takes approx. 60 minutes. Surface finish was (Ra) < 0.1 µm, required for the finishing operation after turning.
