USED REFURBISHED OKUMA MA 400 HA HORIZONTAL MACHINING CENTER
USED REFURBISHED OKUMA MA 400 HA HORIZONTAL MACHINING CENTER
Location:Cologno Monzese, Italy
Description
The Okuma MA 400 HA horizontal machining center, used and overhauled, is an excellent choice for those looking for precision and
reliability. Equipped with OSP E 100 M control unit, this model has a usable surface of 400 x 400 mm and can
support a maximum load of 400 kg. The X, Y and Z axis travels are 560, 610 and 625 mm respectively,
ensuring considerable flexibility.
The machine can reach a maximum spindle speed of 8,000 rpm, with a maximum motor power
available of 18/22 Kw and a spindle torque of 270 Nm. The pallet change takes place in 7 seconds, while the change
tool is even faster, with only 1.3 seconds per tool on tool. The machine offers very high precision
positioning, with tolerances of ±0.004 mm and a repeatability of ±0.0015/100 mm.
With a weight of 10,000 kg and maximum overall dimensions of 2.40 x 4.45 metres (2-pallet version), this centre
work is suitable for high volume operations while maintaining high standards of precision. The machine, which manages
up to 40 tool stations, is designed to optimize production operations while maintaining high
performance even under high load.
