Overview of SK703-3040 CNC edm drilling machine

the machine belongs to the high-speed EDM small hole machining equipment. It uses copper tube as the electrode and is guided by the guide. A high-efficiency pulse power supply is applied between the electrode and the workpiece. during machining, the spindle drives the electrode to servo feed under the control of the servo system, and generates pulse high-frequency discharge between the electrode and the workpiece to etch the workpiece in a controlled way. during processing, high-pressure water quality working fluid is ejected from the inner hole of the electrode to implement forced chip removal cooling in the processing area to ensure the smooth progress of processing.
the machining aperture range of this technology is generally φ the depth diameter ratio of 0.2-3 mm with a pore diameter of about 1mm can reach more than 300:1 at most, and the processing speed is generally 1-40 mm / min. It can penetrate directly from the inclined plane and curved surface without being limited by the hardness and toughness of the material. In addition to processing general conductive materials, it can also process stainless steel, hard alloy, quenched steel, high-temperature heat-resistant alloy, copper alloy Titanium alloy and other difficult to machine conductive materials.

Machine tool design of SK703-3040 CNC edm drilling machine

the machine bed, column, spindle box and other key parts are made of mihanna (close drying) castings, with stable organization and permanent quality. The casting is calculated and analyzed by computer with finite element analysis method. The reasonable structural strength and the matching of stiffeners provide high mechanical rigidity.
the casting structure adopts integrated forming technology and box structure. Large pentahedral processing machine is used for processing, which is completed by clamping at one time. the machine tool has high rigidity, high strength and excellent geometric accuracy. It can ensure the long-term stability and high precision of the machine tool.
the main shaft is provided with four shafts. the worktable is equipped with X and Y axes, adopts ball screw and ball guide rail, and is driven by Panasonic AC servo motor to complete the movement of each hole position of the workpiece. the vertical shaft is equipped with W-axis, which is a linear motion axis to adjust the height position between the guide and the workpiece. the column adopts linear guide rail and Panasonic AC servo motor. the spindle head is equipped with z-axis, which is the servo motion axis of the roller. the subdivision stepping motor is used to complete the servo feed of the fine filament motor in processing. the guide rail, screw nut, bearing and gear of the equipment cutting shaft are lubricated with grease.
