Advanced and reasonable machine structure

1) Mechanical part

a. Machine structure with a good rigidness is stable and reasonable and hard to be

deformed so as to ensure accuracy.b. The connection form of spindle head is with imported DC torque motor dragging and

cog belt transmission.

c. Guiderail applies V style and surface design, which is characterized by strong

rigidness, reversing resistance, high accuracy, good sensitivity, servo fast response

and stable processing

d. The ball-screw hand wheel of X axis and Y axis translates and Z axis uses DC servo

motor. They all apply P4 level bearing.

e. The guiderail of both X and Y axes uses high-accuracy and anti-friction plastic,

having the features of high accuracy, rapid reaction, good sensitivity and long service

life.

f. Three axes use digital readout system.

g. The machine can arbitrarily use 2 reliefways, blunting oil or pumping oil, and can also

choose processing without dipping into the oil.

h. The machine can process cavity, hole and special shape parts on the material of

copper, graphite and steel.

i.

Lubricating system adopts recycling mode and the guiderail lubricating action once

completes and also keeps clean appearance.

j.

Work cycle filtration system employs efficient and low-noise centrifugal pump and

paper filter, which is available for providing, dumping, blunting and pumping oil.

2) Electrical part

a. Applied with industrial PC control machine, z axis single axis CNC,three shaft position

showing on computer screen, and with all three axis grating using, the positioning is

precision and reliable, and by the way, operation is very simple. What you need to do is

just enter the setting data of z axis so that the operation varied from rough processing to

finish processing can be automatic accomplished.

b. Moisture-proof, rust-proof, PCB board designc. The processing procedures and processing conditions can be inquired and modified

during machining without cutting off the power. As a matter of fact it will save a lot of time

of modifying.

d. With automatic A.R.C. carbon deposition prevention examines device, workpieces will

be prevented from damage.

e. Very large scale of integrated circuit, and the power tube uses VMOS composite

power mosfet.

f. Large area and deep gap independent circuit design

g. PWM servo system, and standard DC servo motor

h. High pressure overlap synchronous discharge system

i. Square wave and energy level output

j. Superfine processing circuit

k. Voltage stabilizing ability ± 20%

l. Copper electrode, the graphite electrode separation circuit, independent parameters

processing

m. With abundant expert bases resources system,

according to different requirements

of the processing, it can automatically match the corresponding processing parameters

and discharge parameters that can be automatically edited, and it can choose rough,

medium and small, very fine processing conditions. It is an unlimited period system. with

more paragraphs processing procedure setting function.

n. The Z axis superior precision processing position repeate confirmation

o. Pulse power discharge time is within 2 ~ 1200, with 18 files to choose from; Rest time

in between 1 ~ 9 choice; Minimum pulse width is 2. The processing is stable and rapid,

and the electrode consumption is small and the surface accuracy is even.

p. Circuit has a liquid surface, liquid temperature, automatic monitoring, fire prevention,

probe, discharge detection, processing depth detection (depth to the automatic alarm),

ARC carbon deposition prevention and so on many security function and device.

q. The power structure contains several functional plates that can be pulled out, self

diagnosis system and LED state display are also available, it's convenient to maintain.

r. Oil level control, automatic stop processing devices. Light sensor, can automatic response, so that fire extinguisher spray and cut off the

power supply

t. Aerosol type automatic response fire extinguisher, safety, no pollution, no damage to

the highest machine tool and die

u. The fuel tank is equipped with a halogen lighting lamp.

3) CNC system configuration

a. P3 CPU industrial PC

b. Random control software system

c. 15 Inch LCD displayer.
