DMG Mori Novel VMC features rigidity, precision
The milling unit is based on an innovative design concept.
DMG Mori has further developed its range of vertical machining centres, and the first model – the DMC 650 V – features a unique machine concept for higher performance and flexibility, the company said.
The milling centre concept is based on a machine bed made of mineral casting, upon which rests a rigid table with a clamping surface of 900 x 570mm.
The machine column, made of cast iron, forms the basis of the X/Y slide. Thus, only the tool is moving, which, in combination with the fixed table, allows for workpiece weights of up to 800 kg, the supplier said.
The rapid traverses in all axes are quoted at 36m/min. According to the manufacturer, the machine, which was first available to the market in November, comes with a spindle with 14,000 rpm and 121Nm as standard; spindle versions of up to 24,000 rpm and an SK 50 spindle with 10,000 rpm and 303Nm for heavy machining are also available, the company noted.
The tool magazine with 20 pockets can optionally be extended to 30, 60 or 120 pockets.
To further improve accuracy, all ball screw nuts and linear guides are cooled via contact pressure rails to effectively dissipate frictional heat, the company said.
The new DMC 650 V is said to be suitable for not only sophisticated single-item production, but also serial production as well as heavy machining with high metal removing rates.
