During the operation of the Dongguan CNC processing center, there is a certain gap between the screw and the nut. With the increase of the operating time of the equipment, the gap gradually increases due to wear. Therefore, the corresponding gap compensation of the reverse movement is the main factor that overcomes the shoulders generated on the surface of the processing surface. The gap measurement usually adopts a percentage meter measuring method, which requires error control.
However, it should be noted that the volume and regulations and the volume rods should not be extended too high or too long, because during the measurement process, due to the long cantilever, the quantitative section will be moved by force. error.
Improper selection of tools during CNC processing can also cause size errors. During the cutting process, the tool removes the material through the main cutting blade. However, after the arc passes through the quadrant and the second cut blade of the arc and the tool is cut, the second cutting blade can participate in the cutting. Therefore, when selecting or grinding tools, you must carefully consider the wedge angle of the tool.
During the CNC processing process, if the amount of machining is not exactly, errors will occur. In the process of implementing parts design performance, whether the processing of the processing surface of the CNC processing surface is even an important reason for whether the molding surface can meet the design requirements. Because the amount of processing is not exactly, it is easy to cause "re -mapping" errors. Therefore, for parts with higher surface shape requirements, the amount of processing and processing should be made as much as possible before forming, or multiple contours should be met to meet the design requirements.
CNC processing has clear regulations on the environment of the workshop, and the heat source needs to be reduced: the focus is that the spindle bearing speed, gap adjustment and reasonable pre -tightening. For thrust bearing and cone roller bearings, due to its harsh working conditions and high incidence of heat, if necessary, you can use the thrust angle to contact the ball bearings to minimize the friction and fever of certain parts.
CNC processing also requires heat insulation: keeping the heat from staying away from the spindle, such as isolation motors and transmission, and using separate transmission. CNC processing also requires heat dissipation: strengthen lubrication and cooling, and use oil -cooled and cold methods to speed up heat dissipation. Reduce the effect of heat deformation: No matter what method is adopted, it can only reduce thermal deformation, and it is difficult to completely eliminate thermal deformation. Therefore, measures should also be taken to reduce the effects of thermal deformation.
