CNC automatic machine tools should be installed on a solid foundation, and the location should be away from the vibration source; avoid sunlight and heat radiation; place in a dry place to avoid the influence of humidity and airflow.
If there is a vibration source near the machine tool, an anti-vibration groove must be set around the foundation.
The machine tool is placed on the foundation and should be leveled in a free state, and then the anchor bolts should be evenly tightened.
For ordinary machine tools, the level reading should not exceed 0.04 / 1000mm, and for high-precision machine tools, the level should not exceed 0.02 / 1000mm.
When measuring the installation accuracy, it should be performed at a constant temperature, and the measuring tool needs to be used for a certain period of time.
When installing the machine tool, make every effort to avoid the installation method that causes the machine tool to have forced deformation.
When the machine tool is installed, some parts of the machine tool should not be removed casually. The removal of the parts may cause the redistribution of the internal stress of the machine tool,
which will affect the accuracy of the machine tool. Preparation before commissioning
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.
The machine tool itself has high precision and rigidity, which 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;
It has higher requirements for the quality of operators and higher technical requirements for maintenance personnel.
Main machine, he is the subject of CNC machine tools, including machine parts, columns, spindles, feed mechanisms and other mechanical parts. He is a mechanical part used to complete various cutting processes.
CNC device is the core of CNC machine tools, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, used to input digital part programs, and complete storage of input information, data Transformation, interpolation and various control functions.
