Okuma MP-46V vertical machining centre targets micron accuracy mould making
The 3-axis Okuma MP-46V vertical machining centre, available from UK agent NCMT, is aimed at tool and mould makers that require repeatable accuracy down to microns. The 2,281 by 2,736 mm footprint, 7 tonne MP-46 V supports workpieces on a 760 by 460 mm table and has linear XYZ travels of 660, 460 and 360 mm, respectively, with 24 m/min rapid traverse in each.
Okuma has employed its thermo-friendly concept, which is based on symmetrical construction, embedded sensors, control algorithms and compensation for the influence of temperature fluctuations on kinematics and machine spindle. In addition, temperature controlled ballscrews in all linear axes contribute to thermal stability and precision in continuous operation.
The MP-46 V is controlled by Okuma's own OSP-P200M. Using the manufacturer's linear scales with 0.1 micron resolution and its Super-NURBS function, the machine achieves top precision and optimum contour accuracy without loss of dynamics, says NCMT. Integral tool measurement is provided by a Blum laser sensor.
The 15 kW/20,000 rpm HSK-63A spindle allows roughing, as well as finishing with very delicate tools. The spindle through-coolant is designed for 70 bar and the tool magazine has 32 stations
