Precautions and structural features of CNC machine tools
Fine machining CNC machine tool: It is a machine tool that uses digital information to complete active control. It uses the code composed of regular words, numbers and symbols to compile the information related to the processing parts into a processing program sheet according to a certain pattern, and then inputs it into the numerical control equipment through the control medium. After the analysis and processing, the numerical control equipment announces various signals and instructions corresponding to the processing program for active processing.
The ultra-fine CNC machine tool system mainly consists of three parts: spindle, transverse feed organization and longitudinal feed organization. The main shaft is supported by an air magnetic bearing and driven by a motor with a frequency converter. The transverse feed organization and the longitudinal feed organization are both granite sliding table and square guide rail structures. Each servo motor directly drives the ball screw to drive the sliding table to move on the guide rail.
Attention for the use of fine machining CNC machine tools:
1. Power supply requirements;
2. The CNC machine tool shall have operating procedures: protection and maintenance on time, recording and protecting the site in case of defects, etc;
3. CNC machine tools should not be sealed for a long time, which will lead to storage system defects and data loss;
4. Pay attention to training and equipping operators, maintenance personnel and programmers
5. Application environment of CNC machine tools: it is better to place CNC machine tools in a constant temperature environment and away from equipment with large vibration and electromagnetic interference.
Structural features of fine machining CNC machine tools:
1. Completely closed, no pipeline exposed, neat and beautiful.
2. The fast feed speed of the servo motor can reach 20 meters/minute.
3. The lathe is equipped with hard limit, zero return and other function switches, which is safe and reliable.
4. High precision, high efficiency and easy operation. The method of double-track equal-position main track is selected, and the machine tool has good rigidity.
5. The double axle rail balance is equipped with three sliders, which is more conducive to improving the rigidity and life of the machine tool.
6. The smooth method uses the circulating continuous oil supply, and the smooth oil is recycled, which can not only improve the life of the machine tool, but also save the cost of the smooth oil.
