Electric spark fast wire cutting machine tool

DK7735Electric spark fast wire cutting machine toolOverview

The basic principle of wire electrical discharge machining is to use tool electrodes to pulse discharge the workpiece for machining. Wire electrical discharge machining does not require the production of forming electrodes, and uses thin metal wires (usually called molybdenum wires) as tool electrodes. The positive pole of the pulse power supply is connected to the workpiece, and the negative pole is connected to the molybdenum wire; Molybdenum wire moves back and forth at a certain speed, constantly entering and leaving the discharge area; Simultaneously spray liquid medium between the molybdenum wire and the workpiece. As long as the operator effectively controls the speed and trajectory of the molybdenum wire on the workpiece, they can cut the required shape and size of the workpiece. The trajectory of the workpiece movement is formed by the coordinate worktable (two controlled stepper motors in the longitudinal and transverse directions) moving in the X and Y directions.

The main unit of DK series CNC wire cutting machine is composed of components such as bed, worktable, wire transport device, wire frame, coolant tank, machine tool electrical appliances, accessories, etc. It is based on the bed, with the worktable, wire conveyor, and wire frame installed on the same base of the bed.

Performance Characteristics

1. The machine tool bed is made of resin sand castings, which have small deformation and high strength after secondary tempering.

2. It has the characteristics of stable performance, high output power, fast cutting speed, high surface smoothness, and low molybdenum wire loss. Lower molybdenum wire loss significantly reduces processing costs.

3. Integrated programming and control: Complex graphics can be converted from CAD to DXF, real-time tracking of processed graphics, display of multiple processing states, and also have functions such as power outage memory, short circuit rollback, wire breakage protection, automatic shutdown, and arbitrary angle rotation.

4. The brand wire cutting frequency converter is used to control the wire transport motor, with stepless speed regulation and contactless commutation with induction switch. There is no spark interference or commutation noise during commutation, and the motor runs smoothly, improving the reliability and safety of the machine tool.

5. The machine tool adopts a fully enclosed environmental protection cover.
