Punch

This punch was machined on a Mikroturn® 100 in a single clamping operation. The goal was to replace the current multistep grinding operations by a faster process. With hard turning you can pre- and finish machine the punch in one set-up, while maintaining the required accuracies. The total cycle time of 164 seconds is considerably faster than grinding.
