ABSTRACT:
A CNC tungsten steel cutting machine suitably used to cut a metal material, such as tungsten carbide steel, includes an operational platform, a cutting mechanism, a feeding mechanism, a delivering mechanism, and a control panel. When a metal material to be cut is received in a feeding tray of the feeding mechanism, lifting control rods of the feeding mechanism lift the metal material until the metal material is temporarily positioned. Once the latest metal material is completely cut, the lifting control rods push the next metal material, so that the next metal material moves into the V-shaped guiding groove. Then, the delivering mechanism delivers the metal material forward until the metal material is located at a press location of the V-shaped guiding groove. After this, the metal material is cut by a grinding wheel of the cutting mechanism, and then dropped into a collection device adjacent to the operational platform.
