Main operation process of CNC milling machine:

Return to reference point operation

Before the program runs, the machine tool must be returned to the reference point, that is, the tool rest returns to the reference point of the machine tool.

Generally, the manual reference point return method is adopted when starting up, and the operation method is as follows:

Manual operation

Use the switch, button, or hand wheel on the operation panel of the machine tool to move the tool manually, so that the tool can move along each coordinate axis.

• Place the mode selector switch in the jog position.

• Select the moving axis, turn the coordinate axis selection key on the control panel to the corresponding coordinate axis, and the machine tool will move in the selected axis direction.

Place the mode selection switch of the control panel at the position of the handwheel, select the manual magnification, turn the manual pulse generator, turn right to the positive direction, and turn left to the negative direction.

Automatic operation

Operation steps of memory

• The program is stored in memory in advance.

• Select the program to run.

• Place the mode selector switch in the automatic position.

• Press the cycle start button to start the automatic operation.

• MDI operation: input the command of a program segment from the crt/mdi operation panel to execute the program segment

• Select automatic mode.

• Select a program.

• Press the cycle start button on the machine tool operation panel.

• Execute automatic operation if the automatic operation has been started, the operation of CNC.

• Stop of automatic operation: input the stop command at the place where the program needs to stop in advance and press the button on the operation panel to stop it.

Protection of CNC milling machine

If the red indicator light is on, it means that the machine tool gives an error alarm and cannot operate normally. The machine tool replacement alarm generally includes a spindle alarm, controller alarm, and lubrication alarm.
