Generally speaking, stepper wire cutting machine is mainly composed of three parts, respectively: mechanical, working fluid system and electrical, each part has its own different roles and functions, among which:

1, working liquid system: the working liquid system is generally composed of working liquid tank, working liquid pump, liquid inlet pipe, liquid return pipe, flow control valve, filter cover or filter element. The main function is to concentrate the discharge energy, take away the discharge heat to cool the electrode wire and the workpiece, and eliminate the electrical corrosion products.

2, mechanical: stepper wire cutting machine mechanical part is the foundation, its accuracy directly affects the working accuracy of the machine tool, but also affects the full play of the electrical performance. The mechanical system consists of machine tool bed, coordinate table, wire transport mechanism, wire frame mechanism, taper mechanism, lubrication system, etc. Machine tool bed is usually box-type structure, is to provide the installation platform of each component, and is closely related to the accuracy of the machine tool. Coordinate table is usually composed of cross drag plate, rolling guide rail, screw moving pair, gear transmission mechanism and so on. It is mainly the relative motion between the electrode wire to complete the processing of the workpiece. The wire transport mechanism is composed of a wire storage cylinder, a motor, a gear pair, a transmission mechanism, a reversing device and an insulating part, etc. The motor and the wire storage cylinder are connected and rotated to drive the electrode wire to move at a certain linear speed, and the electrode wire is neatly wound on the wire storage cylinder. The line frame is divided into single column cantilever type and double column gantry type. Single column cantilever type divided upper and lower arm, the lower arm is generally fixed, the upper arm can be lifted and moved, and the guide wheel is installed on the online frame to support the motor wire. Taper mechanism can be divided into swing type and cross drag plate structure, swing type is the upper and lower arm through the lever rotation to complete, generally used in large taper machine. The cross drag plate type is completed by moving the electrode wire to expand and expand, which is generally suitable for small taper machines. Lubrication systems are used to alleviate wear, improve mechanical efficiency, and reduce power losses. It can play the role of cooling, corrosion inhibition, vibration absorption and noise reduction.

3, electrical: stepper wire cutting machine electrical part includes machine tool circuit, pulse power supply, drive power and control system. The machine tool circuit mainly controls the operation of the wire motor and the working liquid pump, so that the electrode wire can continuously cut the workpiece. The pulse power supply provides the spark discharge energy between the electrode wire and the workpiece for cutting the workpiece. The drive power supply is also called the drive circuit, which is composed of a pulse distributor, a power amplifier circuit, a power supply circuit, a predischarge circuit and other control circuits. It is a power supply that provides power to the stepper motor and is used to control the stepper motor. The control system is mainly to control the movement of the table drag plate (trajectory control) and the discharge of the pulse power supply (machining control).
