A guide on how to operate a CNC lathe

CNC lathe should be one of the most widely used machine tools in machining. Its operation steps include startup inspection, clamping the workpiece, returning to the positioning point, inputting the program to gradually process, finishing the machining, checking and unloading the workpiece, cleaning and shutting down the seven steps.

1. Start-up inspection: first turn on the main switch power supply, and then open the system software, so that the information content is displayed on the CRT of the CNC machine tool system. Happening.

2. Clamping the workpiece: Before the workpiece is clamped, the operator needs to clean every surface that cannot be stained with iron pins, dust and oil. And it is necessary to use a file knife or a whetstone to remove the burrs on the surface of the workpiece. The steel blocks used for clamping must be ground and polished with a CNC grinder to make all surfaces smooth and level. Iron pads are generally placed at the four corners of the workpiece. For parts with too large spans, the contour iron pads must be placed in the middle; according to the size of the drawings, use a ruler to check whether the length, width and height of the workpiece meet the standards .

3. Return to the positioning point: After starting the machine, eliminate the direction change, press the reset switch (RESET), and then adjust the mode switch to the starting point reset position and then press the three-axis home point reset button. When the XYZ three axes are all reset to zero, start the machine. .

4. The input program is gradually processed: if the input program needs to be changed, the actual operation must be carried out. In addition, the method switch is placed in the EDIT position, and the program key is used to upgrade, delete, and change.

5. Processing end: After the imported program is processed, the Z axis of the CNC lathe will be pulled up to a certain relative height. At the same time, the spindle (Z axis) of the lathe will stop rotating and the axes of the CNC lathe will stop running. After a program is processed, : It is necessary to carefully check whether the area processed by the program has over-cut, missed, and other conditions. When all the programs obtained by the programmer have been processed, the workpiece will be processed.

6. Check and unload the workpiece: When the workpiece is still clamped by the three-jaw chuck, carry out the size measurement of the workpiece. If the specifications of the workpiece do not meet the requirements, the CNC blade will be compensated appropriately, and the workpiece will be removed when the specifications are up to standard.

7. Clean up and shut down: Stand by when the workpiece is processed and cleaned up. To turn off the equipment, first move the XYZ three axes to the inner part, the ordinate, the machine tool spindle, etc. should stop running, then press the emergency stop button, then turn off the power supply of the CNC system software above the actual operation, and then turn off the switching power supply of the motor control cabinet , Close the power switch of the regulated power supply and the safety doors of the CNC lathe, and the shutdown is completed.
