The chuck 8 is provided with clamping jaws 11. The chuck 8 is fixed on the mounting plate 9. The mounting plate 9 is provided with a second driving mechanism 10 for controlling the horizontal rotation of the mounting plate 9. The mounting plate 9 is connected to a lower connecting guide rail 16 through a support rod 15. The support rod 15 can move horizontally on the guide rail 16 to control the translation of the mounting plate 9; a bracket 17 is provided at the bottom of the cutting mechanism; a control box 7 is arranged on the bracket 17. A controller is arranged inside the control box 7, and the circuit is connected to the control box and communicated with the controller. In this embodiment, the controller is a motor switch and a master control switch. The motor switch button controls the corresponding motor to operate, and the master control switch button controls the current of the entire machine tool to make the entire machine tool in a charged state or a powered-off state. In other embodiments, a PLC controller can also be used to program and control the operation of the grinding wheel and the workbench of the machine tool.

[0026] In the specific production and processing process, the operator fixes the product to be cut on the clamping jaws 11 on the chuck 8. After completion of the fixation, the controller in the control box 7 is turned on. At this time, the entire cutting device is in a standby state. The operator turns on the second driving mechanism 10 of the mounting plate 9, adjusts and positions the product to a suitable position, and turns off the second driving mechanism 10. The second driving mechanism 10 locks the mounting plate 9. At this time, the fourth driving mechanism is turned on. The fourth driving mechanism adjusts the mounting plate 9 to rotate at an angle of 0 to 1050 in the vertical direction. After completion of the vertical adjustment. Next, the operator turns on the fifth driving mechanism to move the workbench 3 to a position on the guide rail 16 to make the distance suitable for cutting. At this time, the first driving mechanism is turned on. The first driving mechanism is placed in the box body 6 of the first driving mechanism. The first driving mechanism controls the lifting of the lifting mechanism 4.
