  1. The model characteristics of PRV-850GH machining center
  PRV-GH high-speed machine series, gantry high-speed high precision die processing machine.
The extreme high rigidity feed, the small and high precision mold high speed and efficient machining.
Gantry type high-speed body structure, the bed weight of 7500KG, super rigid cutting performance, high smooth and fine surface.
It is widely used in auto parts and mould production.
1) BBT40, 12000rpm/min high rigid straight-junction high-speed spindle.
2) X, Y, z-axis with roller rail, high-speed feed, high speed power cutting and heavy load.
3) The structure design of the pedestal, doorpost and crossbar structure, stable structure. This design rigidity is five times the design of c-type, and the servo rigidity is 3-5 times of c-type design, which can reach level 9.
4) High rigidity, double nut high speed mute ball screw rod, greatly reduce the noise value, and can withstand the operation environment of 2 g. Accuracy et al. JIS C0 ~ C7, transgrade C6 ~ C10.
5) Positioning accuracy: 0.005mm/full stroke, repeat positioning accuracy: 0.003 mm/full stroke.
