Machine Center EMV-850E w/full auto operation

Aug. 7, 2009 - PRLog -- *Newest Mitsubishi M70A Controller w/ full function.
*Ruggedly constructed 4 boxway base and box type structure on other major parts for outstanding rigidity and stability.
*High precision ball screw on 3 axis are pre-loaded and directly coupled to eliminate thermal displacement, which ensuring high repeatability accuracy.
*High precsion ball screw are modular assembled. Screws parallelism and squareness accuracy are calibrated to within 0.005mm in full length.
*Precision scraping assures long term accuracy and maximum wear resistance.
*The axis motor are directly coupled to the ball-screw, it ensures the least backlash and long lasting accuracy.
*The standardly equipped heat exchanger features excellent heat dissipation, that reduces trouble possibility and extends life of electronic.
*Spindle w/oil cooling system.

1, Base:
The massive meehanite casting with enforce ribs design to minimize cutting vibration and ensure machine's accuracy and reliability.
2, Way Slide:
Two choice of slide ways, there are hard rails style (12 scraping points per square inch) or HIWIN high-rigidity linear guide ways on 3 axes yield rapid and accurate cutting capacity which results in an increase in production efficiency.
With automatic lubrication system.
3, Saddle and Column:
High rigidity structures casting like base, column, saddle...etc., using high quality cast iron that accomplished with annealing, structure is stable, distortion low, the above conditions ensure long term machining accuracy.
4 rail slide way design which enable saddle travel without draping and can stand heavy load. Wild slide design gives both high rigidity and stability.
4, X/Y/Z Axis:
Double supported C3 level ball screws.
Direct-driven servo motors are used for axial movements.
5, Spindle:
Big diameter bearing (70mm) provides high rigidity.
NSK spindle angular bearing < 3+2 > supported.
Up to 8000 rpm high spindle speed. < 12,000 rpm for Opt. >
Oil chiller the refrigerated spindle cooling system circulates cooling oil to maintain a constant temperature.
6, Automatic Tool Changer:
The ATC system and all machine functions have been throughtly tested.
