(2) Main performance indexes and technical requirements
A. Machine is designed according to analyses of resistance to draw, resistance
To press and reaction by computer.
B. Casting is used FC-35 by national weathering and all kinds of treatment, it wears well and its precision is changeless.
C. Machine structure is reasonable without distortion, of good rigidity to insure
Process precision.
D. Rails are "V "shape, can move lightly under heavy load and good precision Z
Axis is used Japanese "SANYO" DC servo motor.
E. High precision bears, the working table are used rails with "TAFULO" face.
F. Danish "GRUNDFOS" oil pump or Italy "GALPEDA" oil pump.
G. Three axes SINO grating ruler.
H. Can arbitrarily choose the methods of removing scrap iron, sweeping
Oil or sucking oil, also choose process that the workingpiece is not submerged in oil.
I. It suits to process cavity, hole and special shape parts in copper, plumbago, steel.
J. Lubricating system is used callback way, lubrication of rail is completed once, and retains cleanness of appearance.
K. PCB boards is moistureproof, anticorrosive, gold-filled.

(3) CNC system technical performance
A. There is automatical A. R. C carbon surveillant device to prevent destroying workingpiece.
B. Steady circuit of big area electrode.
C. High and low clearance individual circuit.
D. PWM servo system, standard DC servo motor.
E. Synchronous discharge system of high voltage superposited.
F. Square wave and equal energy output.
G. Circuits of super-fine process.
H. Capacity of mirror process (negative pole).
