DK7735 edm cut for sale

 

 

Features:

 

Machine tool Features:
Max. feature of this serial product lies in the fact that it has no special requirements to the processed metal material properties. In principle, it can process all the conductive materials such as super-hard and hard alloy, quenching materials, stainless steel ductile materials, various magnet steel fragile materials, uneasily-clamped thin wall spares etc. If the machine tool gets the aid of the auxiliary extra-large specification of  "Taper Cutting Device' and  "Responsive Micro-Computer System" produced by this Company, then it can gain the satisfactory results in processing all kind of the special spares which terrify other machine tools.

Main Use:
It processes various molds such as rubber and plastic molds, punch die and so on.
It processes the special materials of fragile materials, stainless steel ductile materials, super-hard materials.
It processes the complex-shape spares such as the tapered upper and lower specially-shaped spares and so forth.

1 Bed:

The machine tool is the cast iron box.

Its upper part takes the tray shape.

On the bed, there are worktable, wire drive device, wire support and floodlight.

 

2 Coordinate worktable:     

The coordinate worktable is composed of the worktable, lower trailing bar, precision roller (slide) screw rod pair and the gearbox.

Use roller track structure for the horizontal and lengthwise movements of the trailing bar.

The worktable movement is realized through the stepped motor, the deceleration gear set and the screw rod pair.

The screw rod nut is pre-tightened axially so as to make the gap between the screw rod and the nut close to zero.

There are 2 T-shaped grooves on the worktable for fixing the clamps.  

 

3 Wire drive device:    

The wire drive device is composed of the wire storage cylinder, trailing bar, gear set, slide screw rod pair, bearing house and base.

The wire drive device realizes the high-speed to-and-fro movement of the wire electrode.

The wire storage cylinder is reliably insulated.

The motor drives the wire storage cylinder rotation through the flexible shaft coupling.

The shift gear set drives the screw rod, which drives the trailing bar to discharge the wire so as to realize the circulative use of the wire electrode. 

Use a group of travel switches to control the frequent reversion of the trailing bar of the wire storage cylinder.

Adjust the distance between the shift forks according to the wire discharging width of the wire storage cylinder.

Leave 3mm wide wire electrode as the non-working section at each end.

If the wire electrode has diameter more than 0.18 mm, order separately change gear set.

During the operation of the machine tool, be sure not to move the waterproof cover on the side of the wire storage cylinder.

 

4 Wire support:   

The wire support is used to support the wire electrode.

It is composed of the pillar, upper arm, lower arm, conductive block and the guide wheel.

The upper arm can move upward and downward so as to adjust the span between the upper and lower guide wheels and to suit the machining of the work pieces with different thickness.

The guide wheel and the conductive block are encased into the wire support and insulated from the upper and lower arms.

The wire discharge wheel (wire blocking rod) at the back ends of the upper and lower arms can avoid wire overlapping.

The water valve is installed at the lower part of the column.

The two knobs on the panel are used to adjust the operation liquid flow rate from the upper and lower nozzles.

The taper head (coordinate cross trailing rod) is installed at the top of the upper arm so as to realize the movements of the guide wheel in U and V axis, to form some angle between the wire electrode and the worktable and to realize the tapered cutting.

The machine tools with maximum cutting taper 30° use the wabble mechanism to realize the simultaneous deflexion of the upper and lower guide wheels so as to ensure the big taper machining precision.

 

5  Operation liquid system:

It is used to provide the operation medium, that is, the operation liquid with certain insulation function.

At the same time, it can cool down the work piece and the wire electrode.

The water pump pumps the operation liquid for wire cutting to the machining area.

This is in favor of the sparkle discharge and the scrap discharge.

The operation liquid flows back to the operation liquid box through the water pipe and it is recycled after filtration.

The residue settles in the waste box.

The operation liquid box shall be cleared up regularly and the operation liquid shall be replaced timely.

Use the tapped water or diluted water to prepare the operation liquid according to the mixture ratio.
