The mechanical part of the wire cutting machine tool is the foundation, and its accuracy directly affects the working accuracy of the machine tool, as well as the full play of electrical performance. The mechanical system consists of machine bed, coordinate table, wire transport mechanism, wire frame mechanism, taper mechanism, smoothing system, etc. The machine bed is usually of box-type construction.

   is a device platform that provides each component, and is closely related to machine tool accuracy. The coordinate table is usually composed of cross carriage, rolling guide, screw motion pair, gear transmission mechanism and other parts. It is mainly the relative movement with the electrode wire to complete the machining of the workpiece. The wire conveying mechanism is composed of wire storage drum, motor, gear pair, transmission mechanism, reversing installation and insulating parts.

  The motor and the wire storage drum are connected and rotated to drive the electrode wire to move at a certain linear speed, and the electrode wire is uniformly wound on the wire storage drum. The wire rack is divided into single-column cantilever type and double-column gantry type. The single-column cantilever type is divided into upper and lower arms. The ordinary lower arm is fixed, and the upper arm can be moved up and down. The guide wheel is installed on the wire frame to support the motor wire.

  The taper mechanism can be divided into a shaking type and a cross drag plate structure. The shaking type is completed by the rotation of the upper and lower arms through the lever, which is generally used in large taper machines. The cross carriage type is completed by moving the electrode wire to expand and contract, and it is generally suitable for small taper machines. The lubrication system is used to relieve mechanical wear, improve mechanical efficiency and reduce power loss. It can play the role of cooling, corrosion inhibition, vibration absorption and noise reduction.
