3. Machine structure
The machine is composed of the mechanism component, electric controller and
coolant system.
The mechanism component is consisted of machine body, working table, wire guide
frame, taper cutting mechanism, wire traveling unit, working tank, fixture, water-
repellent cover and coolant system etc. The linear roller guide ways and the super
high precious ball screws are applied in the machine type below DK7750 (also
including DK7750). One the other hand, the linear ball guide ways and the super high
precious ball screws are applied in the machine type above DK7763.
The span of the wire guide frame is adjustable to different type machine and the guide
wheels are designed to double-support structure.
① The machine body
The material of the cast is HT250, which makes the machine body has high load
intensity and the ability to resist distortion. The vibration-resisted stow-irons are used
in the connection of the machine body and groundwork. The installation and
adjustment are convenience. The up saddle and the middle saddle are set on the top of
the machine body, which are driven by X and Y ball screws.
② The wire traveling unit and the wire guide frame
The to-and-fro rotation of the wire-winding drum drives the electrode wire
reciprocating running. At the same time, the guide wheels and the wire let wheels
keep the movement of the electrode wire smoothly. The top and bottom electrified
blocks are used for electrifying, but if needed we also can use wire-winding drum to
realize electrifying.
③ The taper cutting mechanism
It’s driven by two step motors to realize U and V movement, which can make the
machine accomplish 4 axis (X, Y, U, V) motion together. And according to the taper
cutting mechanism, the machine can execute taper machining.
④ The working table
There, the fixtures are fixed on the working table with T-shape slots i.e. the up saddle.
⑤ The coolant system
The coolant system is composed of water tank, the working fluid, the flux valves, the
pipe unit and the fine filter unit which can make the working fluid used repeatedly.
The working fluid is very important to the machining, that is to say, it can affect the
stability of machining and the surface quality of the machining workpiece. So you
should change the working fluid after a period, when it’s dirty and ropy. When the
pressure meter value is above 0.2Mpa, it suggest you should change the filter core.
⑥ The fixture and the spare part
• About the fixture:
The pane fixtures are only for below type DK7750 WEDM and the shape
fixtures are used on the others type WEDM.
• About the spare part:
There is assembly and disassembly components, wire tighten components,
bearing disassembly tools and the rotating handle in the spare part box.

5.1 About WCUT-2010 control system.
The electrical discharge machining happened between the electrode (which normally
is Molybdenum wire or Tungsten and Molybdenum alloy wire) and the workpiece by
using of the high frequency impulse power supply and the high peak current to bring
high heat and high energy to erode the workpiece.
WCUT-2010 WEDM Control system platform isa new and predominant controller in
China, which is designed by us at recently.
The transducer control wire cutting directly in WCUT-2010 WEDM Control system to
realize balance and stability for the changing direction of wire-winding drum, also
reduce the problem of control unit to improve the performance of WEDM. WCUT-2010
WEDM Control system keep the merits of XKG-2005 and have bring improvements
in machining productivity and workpiece surface rough. There are some technologies
first used in High-speed WEDM in China.
There are some circuit elements in WEDM software interface card. For example, the
X,Y,U,V axis step motor interface circuit , high frequency pulse output control circuit,
high frequency sampling input circuit, auto-pause on machining over output circuit
and parameters chosen circuit.
7. 6
The driving circuit of X, Y, U, V motor
The driving circuit of X, Y, U, V motor are disposed of the dictates that come from
“WEDM circuit board” control card to display the message in LED and to drive the
motors to run.
The control main board
The wire-running control circuit, pump control circuit, high frequency power supply
control circuit, wire-broken alarm circuit, stroke procetion of wire-running motor
circuit, switching off high frequency on wire-winding drum change direction circuit,
wire-running motor speed control circuit, long or short wire traveling control circuit,
high frequency pulse grouping control circuit, high frequency monofier circuit (the
pulse width, pulse interval and power pipe adjustment.), machining parameters chosen
circuit, machining power supply chosen circuit and single side discharging chosen
circuit are included in the control main board.
Pulse power board
The pulse power board is used for amplifying the pulse-message that come from the
pulse monofier board to accomplish electrical discharge between the workpiece and
the electrode.
About the failure prompt
When wire broken is happened during machining, the controller can switch off the
wire traveling motor, the water pump and the high-frequency power supply; and then
send a warning alarm. At this time, there is a failure prompt flashing on the VGA
display, only because the controller system can’t receive the sampling message and
retreat it as a short circuit happening. On the other hand, you should solve the
corresponding problem at once. When machining is over, the controller can also
switch off the wire traveling motor, the water pump and the high-frequency power
supply and wait the next dictate.

6. The pulse power supply
6.1 Summarize
“WCUT-2010 “ pulse power supplyis a high-efficient electrical discharge unit, which is
designed by us recently. The pulse supply is an integrated circuit, which can keep the
pulse frequency steady and improve the performances of anti-jamming. High-power
CMOS tubes, which are used by parallel connection make it can output strong current
to improve machining efficiency. There is a outputting of grouping-pulse wave in
“XKG-2005” system, which is suitable for machining the parts of low thickness and
high surface roughness.
The following is the main technical and technologic guidelines in “WCUT-2010”
system.
The voltage of power supply: 3-AC 380V 50Hz
The peak voltage of pulse: ≤DC105V
The pulse parameters: See to item 1 and item 2.

6.2 Principle
“XKG-2005” system is composed of the DC monofier unit, the front large unit, the
power large unit and the sampling unit. (See to figure 6-1)
Figure 6-1
The front large unit is consisted of integrate circuits (MC4049) to make sure that
CMOS driving tubes work on a good condition.
6.3 About parameters choosing on multi-times machining
14. 16
Low-speed WEDM cutting principle which is multi-times and different energy
discharging cutting is used in WCUT-2010control cabinet to get good workpiece
surface rough.
Dimension calculation method about multi-times cutting.
For example:
A 12mm square workpiece which need thrice cutting;
Material:Cr12; Height:40mm; Mo. Wire: Φ0.18mm.
You can setup the machining parameters according to the following items:
Clearance compensation value: 0.09mm;
First offset value:0.07;
Twice offset value:0.02;
Thrice offset value:0mm.
After machining, check the dimensions. If it is 0.02 lower than 12mm, please set
the clearance compensation value again which should be (0.09+0.02/2)=0.10mm.
On the other hand, if the dimension is 0.02 higher than 12mm, please set the
clearance compensation value: (0.09-0.02/2)=0.08mm.
The cutting parameters are different from different material, different thickness
and different Mo. Diameter. Operator should get the best parameter from actual
work.
Note: Normally, the last cutting offset should be 0mm!
6.4 About multi-times machining
Because the Mo. Wire electrode should be discharging repeatedly, the wire must
be waste with more cutting, which makes the wire thinner and thinner. It must
cause to decrease the machining precision. For Φ0.18mm wire, the max. cutting
area is about 20000 mm2
. It’s a suggestion that you should measure the diameter
of wire before machining and you should tighten the wire after cutting guiding
path. If find the wire diameter waste so much, please change it!
You also should care about the following points:
Check the wire vibration when wire running not cutting. (refer to chapter 12)
Check whether the wire cut into the electrified block or not.
Check the working fluid.
Run your cutting program on software simulation to check your programme.
It’s better to keep more supporting to decrease material deforming.
Some phenomena on workpiece cutting surface after machining.
Trace on surface. It’s a hint that wire maybe vibrate, material maybe deform,
parameter setup for offset value maybe not correct.
Black spots happen on two side on cutting area. It’s a hint that the working
fluid is not good for work.
After cutting, please clean it with oxalic acid then rinse it. Dry it with white
cloth and coat it with antirust.
15. 17
7. Transportation
Before transportation, make sure to loose the bolts which connect screw nut to the
saddle and the fixing parts that connect the top saddle and the middle saddle, the
middle saddle and the machine body.
During transportation, to avoid some unstable factor, such as bump badly, incline etc.
when crane transporting the unpacked machine; make sure the hook and the steel wire
is reliable.
When transporting machine wood box, soft steel wire should be used to firm the box
and there are some attentions:
No inversion, side and incline too much.
Packing firmly when transportation.
When crane transportation the box, make sure the steel wire hook the box
firmly and hang on the hook of the crane (See to figure 19 <a>, 19 <b>).
When slinging or letting down, you cannot incline it and bump box bottom
or side, jerk, surge and shake.
After the box is freighted to the aim place, take off the bolts of the cover and
disassembly it first. Before installation, don’t disassembly the baseboards at once, you
should inspect whether the machine is scathing or not first and check all the
accessories according to the packing list and register the checking result.

plentiful, the connection of bolts and nuts is firm. There are not barriers around the
machine and you must clean the ball screws and guide ways. To make sure that the
electric wire and the ground wire are connected reliably then there is no oil leaking.
10.1 About the span adjustment
You should set up the equal span according to the machining thickness of the
workpiece. We suggest that the perfect distance between nozzle 2 or nozzle 3 and the
workpiece is 5mm to 10mm. You can use angle rule or the molybdenum wire
adjustment gauge to adjust the molybdenum wire in a vertical position. Before you
adjust the perpendicular, you should loose the fixing screw on the taper saddle and
then rotate the knob of the step motor. After adjustment, please tighten the fixing
screw on the taper saddle.
! Attention: Before adjusting, please loose the locking screws between the
up-down arm and the column.
About operating and adjusting big taper mechanism please see to figure 9-1.
It is composed of the linear bearing 1, the connected shaft 2, the driven shaft 3 and the
lengthened shaft 4 (See to the figure 9-2). The locking screws connect the driven shaft
and the connected shaft. The shafts moving relatively to the linear bearing
accomplish the swing motion. The moving precision of the linear bearing and the
shafts is so high that the big taper mechanism can work steadily and the precision can
be kept for a long period.
Before the operation and adjustment, please read the following items:
1) When using the driven shaft and the connected shaft to compound to work,
adjust the central distance of the guide wheels within the range of 141mm to
296mm.
2) When using the driven shaft 1, connected shaft and lengthened shaft 4
( L=159mm) to compound to work, adjust the central distance of the guide
wheels within the range of 280mm to 435mm.
3) When using the driven shaft 2, connected shaft and lengthened shaft 4
( L=298mm) to compound to work, adjust the central distance of the guide
wheels within the range of 435mm to 578mm.
During machining, the shaft should be higher to the top of the linear bearing about
50mm to keep the enough moving distance of the linear bearing.
About adjustment the central distance of the guide wheels, please refer to the
following steps:
1) The central distance of the guide wheels ≤ 280mm;
Loose the locking screws between the up-down arm and the column.
Loose the locking screws of the connected shaft and take out the shafts.
Rotate the up-down screw to drive the up-down arm to a new and proper
position. (If motor drives the up-down screw, please push the up or the
down button to realize the operations.)
19. 21
Assembly the shaft to the linear bearing and the driven shaft, and keep
the shaft should be higher to the top of the linear bearing about 50mm.
Fix the locking screws between the connected shaft and the driven shaft.
2) The central distance of the guide wheels > 280mm
Loosen the locking screws between the up-down arm and the column.
Loosen locking screws connecting between the upper and lower bracket
and connected shaft at the connected shaft device.
Rotate the up-down screw to drive the up-down arm to a new and proper
position. (If motor drives the up-down screw, please push the up or the
down button to realize the operations.)
Attention: Before do this, please loose the locking screws between the
up-down arm and the column.
Choose the proper compound of the connected shaft and driven shaft
according to the expected length. And assembly the shaft to the linear
bearing and the driven shaft, and keep the shaft should be higher to the
top of the linear bearing about 50mm.
Attentions: When the up-down arm is driven from the top position to the
bottom position, to be sure to disassembly the connected shaft.
Warnings:
About the span adjustment, please read the instructions carefully.
Otherwise we will not be answer for it.
10.2 The guide wheels adjustment (refer to figure 9-3)
Adjust screw 7 and nut 6 to eliminate the axial clearance of the guide wheels. When
adjustment, you should make sure that the guide wheels rotate smoothly and there is
not axial clearance. When change the guide wheels, please lubricate the guide wheels
and the bearings.
10.3 About the clearance on the working table
When assembly the machine, we have been adjust the clearance to a reasonable range.
So customers should not adjust it again.
20. 22
10. Operation
Be familiar with the machine components and the use of controller before running the
machine. The following is the adjustment methods:
11.1 Turn on the power supply and run the machine without any load. To observe
whether it runs normally or not. The normal items include:
The controller must work well more than 10 minutes.
The machine component work well.
The pulse power supply and the machine electric work well.
The action of all stroke switches is sensitive.
The pipe system of the working liquid system is smooth and the pressure is
normal.
11.2 Injecting lubricate according to the machine lubricate rules.
11.3 Add or change the working liquid every 10 to 15 days.
11.4 Fixing the workpiece.
Verify the perpendicularity between the electrode wire and the working table then
to fix the fixture on the working table.
Clean the surface of fixture and workpiece then make sure that the conduct
electricity is reliable.
When fixing the workpiece, you should find out the datum plane to make sure
that the workpiece is parallel to X or Y direction of the working table by using of
the centesimal meter according to the drawing. The position of the workpiece
should be fit for the cutting range and the workpiece and the fixture should not
touch any parts of the wire traveling unit.
11.5 Coiling the electrode wire.
The wire running speed setup
Transducer is adopted in the wire traveling system of the machine. Please
choose wire-running speed to “2” or “3” on coiling wire. When cutting,
normally we choose the speed to “1”.
The tension setup
The manual coiling wire is applied, so you should adjust the tension according to
practice.
Before startup the machine, please adjust the stroke rams to both sides.
Coil the electrode wire around the protruding axis of coiling wire part, firm the
button, make it passing the wire let wheel to wire winding drum and pin it by a
bolt. At this time, rotate the wire-winding drum to terminal position. Coil it
several circle and push down wire-running ON/OFF button to make the indicator
light turn on, and then run the wire traveling motor to coil the other terminal.
When finished, stop the wire traveling motor and cut off the end of the electrode
wire. Hang the wire tip on the wire let wheel, the wire-keeping bar, the
electrified block, the wire guide wheel, etc. then return it to the wire winding
drum, pin it and coil it reverse direction for several circles.

The electrode wire may loosen only because of elasticity fatigue. After a long
time working, so you need tighten wire again by manual. Notice that the force
for tightening wire should be even. .
Coiling wire
The wire traveling route of the 0°and 6°taper: (See to figure 10-1)
The wire winding drum → The wire let wheel → The up wire guiding stick →
The electrified block → The up guide wheel → The down guide wheel → The
electrified block → The down wire guiding stick → The wire broken protection
stick → The wire winding drum.
The wire traveling route of the 30°and 60°taper: (See to figure 10-2)
The wire winding drum → The wire broken protection stick →The up wire let
wheel → The down wire let wheel →The down guide wheel → The up guide
wheel The up wire let wheel → The down wire let wheel → The wire winding
drum.
Adjust the stroke rams again to keep the distance to two sides is about 5 to
10mm. You should take care that the turning direction of coil and the direction
of the wire traveling saddle to prevent overrun.
Wire running control panel
Attention: Taking off the handle when the wire traveling, which can
avoid dangers. The wire traveling stroke limit is adopted by a
method of the screw and the nut separated. The tail of the screw is
smooth, so when overrunning, the motor is in racing condition. Pushing
the wire traveling saddle and rotate the wire winding drum to make the
screw mate the nut to resume work.

11.6 Operation steps
Turn on the power supply.
Input the machining program.
Adjust the span of the wire guide frame according to the workpiece
thickness.
Fix the fixture.
Coil the electrode wire. (When finished, tighten the wire once to twice and
the force should be even.)
Choose the equal wire traveling speed. (It is determined by the workpiece
thickness and you cannot change the wire traveling speed when machining.)
Turn on the wire traveling motor.
Turn on the water pump and adjust the flux. (Before turning on the water
pump, you should close the adjustable valve. After running the water pump,
open the valve gradually to make sure that the electrode wire is embodied
by the water column.)
Turn on the high-frequency power supply and choose the electrical
parameters. (User can choose the electrical parameters according to the
cutting efficiency or surface roughness. When cutting in, please draw the
clearance of the pulse and after cutting in, adjust it to meet machining
request.)
Run the program. When cutting in, adjust the knob of the adjustable resistor
to make the hand of the current meter stably. (The current meter shaking
gently is allowable.)
When machining is over, turn off the pulse power supply first and then the
water pump and the wire traveling motor. To check whether the X, Y
coordinate arrive at the end-point or not and take off the workpiece from the
workpiece and rinse it to check it.
Attentions: There is a red emergency stop button on the controller
panel. Push down the button when emergency to stop the machine.
11.7 Taper machining
Loosen the firm bolts of U, V saddle.
Adjust the span then the perpendicularity of the electrode wire.
Measure the central distance (H2) between the up guide wheel and down
guide wheel and the distance (H1) between the down guide wheel and
fixture, then the workpiece thickness (H). (See to the following figure)
Input the value of H, H1, H2 and r into the program system to generate
automatically the machining program. (Detail, please refer to “Program
system user guide”.
23. 25
The clearance adjustment of the screw mate on the taper cutting mechanism.
(See to the following figure)
Open the top and bottom cover of the taper cutting mechanism and loose or
tighten the screw mate by a spanner to make the screw mate rotate flexibly
and no clearance in axial direction.
Clearance adjustment of the screw mate

11. About the usage of wire guider
11.1 Scope
The wire guiders are standard parts for equipping with XKG-2005 WEDM. You can
find the functions of wire guider on the following items:
It’s a guider to guiding wire to minish wire-running vibration, so it can
improve the workpiece cutting surface rough.
It can realize ≤1.5° taper cutting on 100mm height workpiece.
11.2 Structure
About the structure of wire guider, please refer to the following figure 11-1.
1. Wire guider house 2. Wire guider 3. Wire guiding block
4. Cover 5. M4x15 Blot 6. M4x30 Blot 7. Hinger
11.3 Requirement and installation
The wire guiders have been correctly equipped and adjusted before sale out. Customer
can use it directly. If you disassembly it, please follow the following steps to set it up.
Take off water spraying part.
Check the position of up and down guide wheels to make sure two guide wheels
in one plane and center to center through the middle line of wire guider house.
Coil wire and tighten wire, calibrate wire perpendicularity (Both X and Y axes).
After adjusting, do not move the guide wheels.
Assembly wire guider on wire guider house. Refer to wire guider structure figure.
Make wire through the wire guider from up guide wheel to down guide wheel.
When wire goes through the wire guider, please make the wire front
as straight as possible.
25. 27
Tighten wire then check the wire perpendicularity. If needed, please adjust the
position of wire guider a little bit. You can loose 2 pcs M4x15 blots and adjust
the wire guider then fix the two blots.
Check parallelism of wire guider bottom surface with micrometer. It should be ≤
0.01mm.
Connect water pipes.
11.4 Some important items about wire guider
After adjusting wire guider component, it should be no changing on whole
machining. Otherwise it will affect on normal cutting work, especially on taper
cutting. Sometimes, when making taper cutting, operator adjust U,V servo axes to
keep wire and workpiece perpendicular. That’s forbidden! If you find wire is not
perpendicular with workpiece, you should adjust workpiece not the wire!
If you want get high surface rough and making multi-times cutting, it’s better to
use wire guider component. If making normal cutting, you can use normal way
which is guide wheel working with spraying part. The spraying part belongs to
spare parts.
If assemble wire guider component, it will affect on taper cutting. So you
only can make ±1.5° cutting with wire guider component. If you want to
make ± 3.0° cutting, please disassemble wire guider component and using
spraying part!

Check wire-running ON/ OFF key on control panel or wire running
button on wire running panel. If only one of two is ok, then check the
wire connection of the failure one. If both of them is out of work,
please check wire broken protection switch, heat relay and stroke
protection switch of wire-running motor.
Check the indicator light on BM2005-3. If it’s ok, then check the
alarm signals of transducer. Otherwise, restart machine again and see
what’s happened? If it’s same problem, it’s a hint that BM2005-3 PCB
is out of work.
c. Noise happened on the wire-winding drum. So you should check whether
there are plentiful lubricant on the bearings, the screw and the nut.
d. Check if there are some blocks between screw and nut, or gears?
12.7 Usual problem about machining

30. 32
13. Maintenance
Before running the machine, you must be familiar with the lubricating system and
lubricating rules (See to figure 13-1 and 13-2) to ensure the machine performance and
usage life.
There are oil cups and oil holes to the lubricate points and the lubricating method is
manual timely. (About the lubricating rules and attention, please refer to the appendix
table 1.)
Keep clean to the machine and oil the lubricating point if the machine has stop for 8
hours. The electrified wheels and the wire-let wheels of the taper cutting mechanism
unit should be rinsed frequently. After rinsing, the dirty oil can’t be flow into the
backwater slot of the working table.
The guide wheels and bearings must be replaced in general after 3 to 4 months using.
If the working liquid system is jammed, dredge immediately. Otherwise the liquid
will permeate through machine, which can destroy the electric components.
The machine is equipped with wire protecting unit. Do away with the waste electrode
wire once wire broken. Isolate the machine from outside vibration and strong
magnetic field and keep clear in the workshop. When the power supply is ±10%
higher than rated voltage, the controller should be connected with steady voltage
power supply or adjustable voltage device (3N-280V3KW).
On the condition that the machine runs two shifts every day and operated as the rule,
its precision can keep for two years. The time that the machine needs heavy repairing
is not less than 8 years.
