Fine-machined CNC machine tools: Machine tools that use digital information to perform active control. It uses the code of the regular characters, numbers and symbols to be processed into a machining program list according to a certain pattern, and then input into the numerical control device through the control medium. After the analysis is processed by the numerical control device, each Active processing of signals and commands corresponding to the machining program.
       The ultra-fine CNC machine tool system has three main parts: the main shaft, the horizontal feed organization, and the longitudinal feed organization. The main shaft is supported by an air magnetic bearing and driven by a motor with a frequency converter. Both the lateral feed structure and the longitudinal feed organization use a granite slide table and a square guide rail structure, and each servo motor directly drives the ball screw to drive the slide. The table moves on the rails.
Fine-processing CNC machine tools to pay attention to:
1. Power requirements;
2. CNC machine tools should have operating procedures: punctual protection, maintenance, and pay attention to record the protection site;
3. CNC machine tools should not be sealed for a long time, which will lead to storage system problems and loss of data for a long time;
4. Pay attention to training and equipment operators, maintenance personnel and programmers
5. The operating environment of CNC machine tools: On the CNC machine tool, it is placed in a constant temperature environment and away from equipment with high vibration and equipment with electromagnetic interference;
Fine processing CNC machine tool structure features:
1. Fully enclosed, no pipelines exposed, neat and beautiful.
2. The servo motor's rapid feed rate can reach 20 m / min.
3. The lathe is equipped with function switches such as hard limit and zero return, which is safe and reliable.
4. High precision, high efficiency and easy operation. The two-track rail average rail method is adopted, and the machine tool has good rigidity.
5. Double-off axle balance equipment with 3 sliders, which is more conducive to improving the rigidity and life of the machine.
6. The smooth method uses the circulating uninterrupted oil supply, and the smooth oil is reclaimed, which can not only improve the life of the machine tool, but also save the smooth oil cost.
Fine machining CNC machine protection:
1. punctual replacement of battery for memory
2. Punctual cleaning of the cooling and ventilation system of the CNC cabinet
3. Strictly observe the operating procedures and daily protection system
4. Protection of the mechanical parts of the spare circuit board
5. Often supervise the grid voltage of the CNC system: the grid voltage range is 85% to 110% of the rated value.
6. Protection of the CNC system when it is not used for a long time: It is often used to energize the CNC system or to make the CNC machine run the temperature program.
7. Fine-machining CNC machine tools to prevent dust from entering the CNC equipment: floating dust and metal powder easily cause the insulation resistance between components to drop, and then present faults and even damage components.
