After the machine's geometric accuracy inspection is qualified, the entire machine needs to be cleaned. Use cotton or silk cloth impregnated with cleaning agent. Do not use cotton or gauze. Clean out the anti-rust oil or anti-rust paint that is applied to protect the guide surface and the working surface when the machine tool leaves the factory. Clean the dust on the outer surface of the machine. Coat the sliding surface and the working surface with the machine tool to make the oil.

Carefully check whether all parts of the machine tool are filled with oil as required, and whether the cooling tank is filled with sufficient coolant. Whether the oil of the hydraulic station and automatic lubrication device of the machine tool reaches the position specified by the oil level indicator.

Check whether the switches and components in the electrical control box are normal and whether the plug-in integrated circuit boards are in place.

Power on and start the centralized lubrication equipment, so that each lubricating part and the lubricating oil path are filled with lubricating oil. Make all the preparations before the machine parts move.

Numerically controlled machine tool is an abbreviation of digitally controlled machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process and decode a program specified by a control code or other symbolic instructions, thereby causing the machine to operate and process parts.

Compared with ordinary machine tools, CNC machine tools have the following characteristics:

● High processing accuracy and stable processing quality;

● Multi-coordinate linkage can be performed, and parts with complex shapes can be processed;

● When the processing parts are changed, generally only the NC program needs to be changed, which can save production preparation time;

● The machine tool itself has high precision and rigidity. It can choose favorable processing amount and high productivity (generally 3 ~ 5 times of ordinary machine tools);

● High degree of machine tool automation can reduce labor intensity;

● Higher quality requirements for operators and higher technical requirements for maintenance personnel.
