[0002] The CNC EDM cutting machine is a device that uses the principle of electric spark erosion to perform metal cutting. It is usually used to process hard, high-strength and difficult-to-process metal materials, such as titanium alloy, high-speed steel, cemented carbide, etc. The working principle is to use the high temperature and high energy of electric spark discharge to corrode metal materials, thereby achieving precise cutting and processing. The advantages of CNC EDM cutting machines include high-precision processing, suitability for hard materials, and no mechanical stress. When the CNC EDM wire cutting machine processes the workpiece, the positioning needs to be manually positioned, and the positioning of the workpiece is relatively laborious, and it is impossible to quickly and accurately position and align, which is inconvenient and makes the processing efficiency low.

[0005] By adopting the above technical scheme, the workpiece to be cut is placed on the second support and the third support, and the horizontal screw is rotated to drive the clamping seats on both sides to move relative to the second support. Finally, the clamping plates on both sides of the workpiece push the workpiece to the middle of the support, and the workpiece to be cut on the support is centered, which is convenient for positioning and alignment of the workpiece and improving processing efficiency; after the workpiece to be cut is centered, the clamping mechanisms on the clamping seats on both sides and the third support are used to press the workpiece to be cut on the workbench, and the three clamping mechanisms are respectively located at the triangular parts of the workpiece to avoid shaking of the workpiece during processing and affecting the cutting efficiency, thereby improving the cutting quality and cutting stability; during processing, the main body of the cutting machine can be raised and lowered according to the size of the workpiece to improve the cutting accuracy.

[0006] The utility model is further configured as follows: the adjustment assembly includes a fixing frame fixed to the workbench, a vertical screw rod vertically rotating on the fixing frame, and a fixing seat threadedly connected to the fixing frame, and the cutting machine body is installed on the fixing seat.

[0007] By adopting the above technical solution, the vertical screw is rotated to drive the fixed seat to rise and fall relative to the fixed frame, thereby driving the cutting machine body to rise and fall relative to the workbench, so as to adjust the position of the cutting machine body according to the size of the workpiece and improve the cutting accuracy.

[0013] By adopting the above technical solution, the horizontal screw is rotated to drive the clamping seats on both sides to move relative to the second support frame, and the clamping plates fixed to the clamping seats extend from the slots and slide relative to the slots to clamp the two sides of the workpiece.
