2, the composition of machine tools:
Machine tools, including workstations, transporting wire, wire frame, working fluid systems and machine tools, electrical and digital control and other parts.
(1) table is used to clamp the workpiece to be processed to achieve automatic feeding. It is mainly composed of upper and lower cross slide, precision ball screw, backlash-free gear and precision rolling (or linear) guide. Carriage up and down along the precision rolling (or linear) guide and its power is reciprocated by a stepper motor through a gear set backlash ball screw reached up to achieve due to lead to a pulse of the working table moving 0.001mm (Or linear) guide, ball screw, no backlash gear group, the carriage has strict requirements, not only high precision but also to have a certain degree of rigidity and a certain degree of rigidity and rigidity, Wear resistance, while using semi-enclosed shield to prevent the work of liquid chip splash.

(2) wire parts
The wire feeding device is mainly used for driving the electrode wire to move at a certain linear speed and laying the electrode wire neatly on the wire barrel. The wire feeding mechanism is composed of motor storage tube, upper and lower carriage, timing belt, commutation device and the like composition.
Its basic requirements are:
(1) on the one hand, the storage tube on the one hand to move, to ensure that the electrode wire in the storage tube neatly arranged.
(2)radial and axial play of wire storage cylinder is smaller.
(3) Reversible feeders are required.
(4) storage barrel body should be insulated with the bed.
(5) fully enclosed part of the transport wire cover, to prevent the work of liquid splash.
(3) wire frame components
Wire frame components mainly by the column, the upper and lower cantilever, guide wheel and taper head and other components.Wire frame parts and the wire barrel parts together constitute the movement of the electrode wire, wire frame is the main function of the electrode wire at a steady line speed movement of the electrode wire plays a supporting role, and the electrode wire working part and the table plane to maintain A certain degree of geometry.
Taper components (cross-type trailer mounted on the upper cantilever) to ensure that the workpiece to achieve 6°/ 80 mm.
(4) bed components
The upper part of the bed is equipped with worktable parts, wire-frame parts and wire-carrying parts. The lower part of the bed is equipped with working fluid tank, electrical parts of machine tools, and parts of bed parts are semi-finished. Enclosed enclosure, both safe and conducive to improving the operating environment.
(5) Wire cutting control system uses industrial computer, advanced computer graphics software and numerical control system, set programming, control as one of the advanced programming and control system, its main functions are as follows:
(1) the upper and lower profiled surface processing, X, Y, U, V four axes together.
(2) programming and control integration, processing can be programmed at the same time.
(3) processing trajectory and processing data real-time tracking display.
(4) using the screen control, mouse operation, convenient, intuitive and easy to learn.
(5) with data power-down memory function, power-on automatic recovery.
(6) The ISOG code compatible 3B code.
Second, products in the domestic leading level of description
1, high-quality castings and aging treatment
Casting Grade: HT2 5 0
Cast aging treatment: artificial aging and natural aging
Casting - artificial aging - rough planing - natural aging (more than six months) - mechanical processing - the assembly of the castings through this treatment to ensure that the machine basic performance of the basic parts of stability.
2, the main parts were all well-known manufacturers (attached). The only way to ensure that we choose matching pieces is always high quality and advanced.

3, a high-precision key equipment, our company's key equipment for the company's key parts of the upper and lower carriage parallelism, flatness, gear box, bearing bearing hole accuracy, upper and lower arm guide wheel seat hole accuracy, wire Tara seat vertical mounting surface played a good role in quality assurance.

Machine tool Features of DK7735 EDM CNC Wire Cutting Machine:
Max. feature of this serial product lies in the fact that it has no special requirements to the processed metal material properties.
