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 power of 18/22 Kw and a spindle torque of 270 Nm. The pallet change takes place in 7 seconds, while the change The tool is even faster, with only 1.3 seconds per tool. The machine offers extremely 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 precision standards. The machine, which manages up to 40 tool stations, is designed to optimize production operations while maintaining high performance even under high load.
