DMG MORI has introduced its 4th generation DMC 80 U duoBlock and DMC 80 FD duoBlock universal machine centres that feature a new B axis milling head with an extended swivel range of 250° with a swivel of 70° in the negative direction.
The company says the larger axis bearing results in a 20 per cent increase in stiffness. The extended swivel range and reduced interference contour in conjunction with the cable conduit integrated into the housing enable a wider range of complete machining operations to be carried out. Idle times are reduced thanks to shortened B axis movements.
With a work area which has been increased in size by 8 per cent to 0.715 dm³ and a Z axis traverse of 850 mm, both the DMC 80 U duoBlock and the DMC 80 FD duoBlock have increased overall rigidity, despite their reduced footprints. This is based on structural optimisation of the reinforced, in some areas wider machine beds and columns, which in both machines are made of high-quality castings (GGG60). In addition, the supporting surfaces of the rigid machine beds have been enlarged and feature stronger size 55 linear guides fitted on the Y axis, and 50 mm diameter ballscrew drives.
It offers milling and turning in a single setup with a DirectDrive table and speeds up to 800 rpm. X, Y and Z axis travels are 800, 1,050 and 850 mm respectively.
