The DM 400 is the new comfort model for fine grinding of medium-hard, hard and brittle materials down to 0.05 mm. This model is based on the well-proven DM 200 but offers improved safety features due to the automatic locking of the collecting vessel and grinding chamber, as well as particularly convenient operation thanks to the motor-driven grinding gap adjustment with digital gap display.
