DSM is versatile enough to handle traditional metalworking requirements as well as the processing of thin, fragile, semiconductor and optical materials. 4-Way Motion is the Key The key to the quality, speed and versatility of the Double-Side Machine involves a principle known as the 4-Way Motion. Utility of the 4-Way Motion reduces machining time, surpassing the 2-way and 3-way capabilities of other double-sided machines.
