DMU 60 eVo Meets Complex Workpiece Demands
The DMU 60 eVo is the newest model in DMG’s eVo Series – having already sold more than 3,000 units throughout the world. In recent years, there has been growing demand for manufacturing complex workpieces, particularly in the aircraft and medical equipment industries. Mori Seiki and DMG have launched the DMU 60 eVo in order to meet this demand. The distinctive features of the DMU 60 eVo include a gantry design for the highest rigidity and precision, improved swivel rotary table, space saving design and optional linear motor drive.
The DMU 60 eVo has a gantry construction in which the X and Y axes are placed in the upper part of the machine. This construction enables the machine to minimize spindle overhang and increase stability and rigidity, thereby maintaining high precision. Additionally, the optimally positioned Y‐axis saddle and the rounded design for the front of the machine provide efficient setups and outstanding accessibility to the working area from two sides.
The eVo Series’ proven swivel rotary table has been further strengthened. The 600 x 500 mm swivel rotary table (corner: φ630 mm) maintains the successful design concept, while doubling the loading capacity to 400 kg. With a swivel range from ‐5 to +110 degrees, the machine is capable of handling a wide range of machining. Turning specifications with a C‐axis rotational speed of 1,000 min‐1 (FD specifications) are also available as an option.
A standard DMU 60 eVo uses a ball screw drive for the X and Y axes (rapid traverse rate: 50 m/min). The optional linear motor drive (rapid traverse rate: 80 m/min) is suitable for customers who need even greater efficiency. The linear motor drive offers high speed and high acceleration feed, and achieves superb positioning accuracy, with a positioning error only one‐tenth of that of the ball screw drive. Additionally, the machine uses fewer consumable parts, which requires less maintenance.
