The new DMC 65 V vertical machining centre applies high-speed cutting, dry machining and universal application in die making and series production with high dynamics and precision. The DMC 65 V sets new standards for vertical machining centres. The new machine construction concept from Deckel Maho Geretsried is a prerequisite for this, with the gantry design being the most prominent change.
It allows complete machining of a stationary workpiece.
The advantages of this technology are obvious because the DMC 65 V is also capable of machining heavy parts at high dynamics without any problems caused by the forces of gravity.
The gantry design also eliminates the weak points of other machine concepts employed for the machining of stationary workpieces.
The DMC 65 V utilises a double synchronised drive for the Y axis.
Both drives are synchronously controlled by separate path measuring systems to ensure that unequal forces which are caused by the spindle travelling in Y have not to be taken up by the guide way.
The moving parts of the DMC 65 V are welded or s.g.
iron structures.
The result is stability and thus increased precision at the lowest possible weight and at high dynamics.
The sturdy construction of the DMC 65 V does not only provide optimum precision but also unprecedented dynamics.
Acceleration rate is 1g and rapid traverses are 60m/min and standard speeds are up to 18,000 rpm complement a powerful performance.
The machine bed is a cast box construction, which was optimised by the finite element method in collaboration with the Darmstadt University.
Vertical walls in the working area, 45 inclined surfaces in the bed area and large openings to the swarf conveyor result in optimum coolant and swarf flow.
The cabin roof opens automatically at the push of a button to receive the workpieces, which are loaded by crane.
The spacious working area gives the operator optimum freedom of motion, which is required when parts are fed.
The precision of the machine is not only guaranteed by its sturdy construction but also by a number of further intelligent high-tech features, such as preloaded roller bearings which provides optimum protection against swarf and coolant in all axes, and ball screws with improved thermal behaviour and inclined thrust ball bearings especially for high speeds.
The thermodynamic design of frame and slide complement the well thought-out machine construction which will set new standards for tool and die making, part manufacture and series production: the DMC 65 V.
