1. CNC vertical vehicle processing sphere causes errors

When processing the spherical and curved surfaces, due to improper adjustment, it is easy to cause convex shoulder and shovel back. The main reasons are:

① System gaps cause

Among the device transmission, there is a certain gap between the screw and the nut. As the device's investment operating time increases, the gap gradually increases due to wear. The main factors of the processing surface generate. The gap measurement usually adopts the percentage meter measurement method, which requires control errors. However, it should be noted that the table seats and the surface rod should not be extended too long, because during the measurement process, due to the long cantilever, the table seat is easy to move, resulting in inaccurate counting, and the compensation value will also occur.

② Improper selection of tools

During the cutting, the tool is removed by the main cutting blade. However, after the arc processing is over, the arc is cut with the auxiliary blade of the tool, and the side -cut blade may participate in the cutting. Therefore, when selecting or grinding the tool, you must consider the wedge angle of the tool.

③ The uneven amount in the processing of workpieces is caused

In the process of allowing parts design performance, whether the amount of processing on the surface of the processing surface is also an important reason for whether the surface surface can meet the design requirements, because the unevenness of the processing remaining can easily cause the "reproduction" error. Therefore, parts with higher surface shape requirements should be as uniform as possible before forming as much as possible or through a multi -processing surface to meet the design requirements.

2. CNC processing sphere to generate error elimination methods

During the processing of the sphere and curved surface, the sphere may have a small two ends in the middle, or the small two ends in the middle. At this time, the radius value of the sphere needs to be controlled. If the middle is large and the two ends are small, you need to increase the radius value slightly. If it is small in the middle and large ends, this radius value is reduced. Try to control the ball error within 0.05mm.
