At the recent DMG MORI open house held at the machine tool manufacturer’s Pfronten factory in Germany, a new 5-axis machining centre was launched aimed at the entry-level market. Less than two metres wide, the compact, competitively priced DMU 40 is capable of fully interpolative 5-axis machining to within microns within a 550mm x 450mm x 420mm working volume.
Of trunnion-mounted rotary table design, the machine is based on the DMU 50 3rd Generation, of which more than 10 000 have been sold worldwide, and features best-in-class components as well as preparation for automated production.
The one-piece machine bed made from grey cast iron, optimised geometry of the Y and Z-axis slideways and the inline spindle with hydraulic clamping all ensure high rigidity. Direct-drive ballscrews in the X and Y axes improve surface quality. For machining flexibility, the swivel range of the B-axis extends from -35° to 110°.
The ergonomic design of the DMU 40 offers optimal accessibility to the work area. Table loading height is 800mm and the distance from the operator to the table centre is short, while it is also possible to load components by crane. A large window and improved lighting provide good visibility. Optionally, the tool magazine may be loaded from the front.
There are three machine options with different equipment packages to meet customers’ individual requirements. The standard DMU 40 has a 12 000rpm spindle and 24-position tool magazine. DMU 40 PLUS features a 15 000rpm spindle and a tool magazine with 30 pockets, linear scales and passive cooling of all main components. DMU 40 PRO is the most accurate and productive model, with active cooling and a 20 000rpm spindle.
The machine may optionally be fitted with automation in the form of a PH 150 pallet handling system or Robo2Go Milling robotic handling of workpieces, allowing customers to take advantage of autonomous production including overnight and at weekends.
