When installing workpieces, fixtures and accessories on the CNC milling machine. Do not hesitate to clean and wipe the iron pins and dirt on the table top and the mounting surface of fixtures or accessories, so as not to affect the machining accuracy.

At the end of the work. The milling cutter should be separated from the workpiece, the handle should be placed in the neutral position, and the working conditions of the milling machine, milling cutter and fixture should be generally checked; Then cut off the power supply, clean the milling machine, and pour lubricating oil on the guide rail surface before succession.

Always do a good job in the maintenance of CNC milling machine. The worktable and guide surface of milling machine are precise curved surfaces, so it is necessary to prevent the impact and collision of heavy objects. When you encounter heavy objects or rough blank surfaces, put wooden blocks on the table and put them down gently. If abnormal conditions such as noise and heating of the spindle bearing are found in the gear box of the milling machine, stop the machine immediately and make a fault. Don't continue to work reluctantly. According to the regulations, the milling machine should be inspected and planned for maintenance.
