New Okuma machines from NCMT at MACH 2010
1 min read
NCMT, sole agent for Okuma in the UK since 1976, will demonstrate, on stand 5228, the Japanese manufacturer's two approaches to high end, multi-functional machining.
The Okuma Multus B200-W multi-function machine for turning components performs 5-axis machining operations using a milling spindle rated at up to 16 kW mounted on a swivelling 225° B-axis. On show for the first time in the UK, the machine has a capacity of 200 to 1,000 mm diameter, with up to 6 m between centres.
The Okuma Multus MU-500VA-L mill-turn centre on show is a 5-axis vertical machining centre, to which has been added turning capability. The design is based on a fully integrated trunnion swivelling horizontally from +20° to -110° and carrying a 360° rotary table; trunnion rotation is up to 50 rpm, with repeatability of 0.001°. This design adds an A and C-axis to the X, Y and Z envelope of 1,250 by 660 by 540 mm, with 40 m/min rapid traverse in the X and Y axes, and 32 m/min in the Z-axis.
The third Okuma machine on the stand will be the Okuma LB3000EX C M 500 mill-turn centre. This is a 2-axis lathe with optional C-axis and driven tooling, as well as having X and Z-axis rapid traverse rates of 25 and 30 m/min respectively. It is available in two bed lengths with distances between centres of 500 or 1,000 mm and a maximum turning diameter of 580 mm.
