Near the end of the year, major factories have gradually begun to enter the state of rest, as an important processing equipment -Automatic CNC Machine also began to shut down. Automatic CNC Machine is a kind of high-efficiency automatic or semi-automatic equipment, which is carried out in strict accordance with the parameters and actions specified in the processing program, and machined parts with the required shape, size and accuracy. In order to allow CNC machine tools to be put into use as soon as possible in the future, we should be soberly aware of the importance of correct use and daily maintenance.

1, keep the machine tool in a good lubrication state

Check and clean the automatic lubrication system regularly, add or replace grease and oil, so that the moving parts of the lead screw, guide rail and so on always maintain a good lubrication state, reduce the mechanical wear speed.

2. Check the hydraulic and air pressure system regularly

The hydraulic system is regularly checked for oil quality, check and replace the hydraulic oil, and regularly clean or replace the filter or filter of the lubrication, hydraulic and air pressure systems, and pay attention to the frequent water discharge of the air pressure system.

3. Check the motor system regularly

Check, clean and replace the DC motor brush and commutator regularly. If the commutator surface is dirty, clean it with white cloth stained with alcohol. If the surface is rough, trim it with fine metallographic sandpaper; If the length of the brush is less than 10mm, replace it.

4, timely to carry out the over-the-limit test of each coordinate axis

Due to cutting fluid and other reasons, the hardware limit switch corrodes, and usually mainly relies on the software limit to play a protective role. Therefore, it is necessary to prevent the limit switch from working after corrosion, prevent the collision of the workbench, and seriously damage the ball screw and affect its mechanical accuracy. During the test, just press the limit switch to confirm whether there is an over-range alarm, or check whether the corresponding I/O interface signal changes.
