The standard of high quality linear optical axis is good surface quality and performance, so three kinds of equipment, such as centerless lathe, straightener and calender, are very important and indispensable. The coreless lathe is mainly used to remove the carbon black layer, impurities, stains, marks outside the linear optical axis. It not only has a good effect on the processing of new materials, but also can be used to renovate second-hand materials.
Of course, the types of linear optical axis is not a single, in order to meet the application of different occasions, there are a length-diameter ratio of less than five short optical axis, there are more than 20 slender optical axis, as well as stepped optical axis, hollow optical axis and crankshaft and other special products. In addition, their accuracy, surface quality and technical requirements are relatively high, usually based on the actual working conditions.
In addition to the difficulties in the process of machining, the installation and use of linear optical axis also have important points to master, otherwise not only the function of linear optical axis can not be fully developed, but also vulnerable to varying degrees of damage. Precision axis
Because of the deformation of the surface of the linear optical axis, the hardness will be further increased. When the hardening layer is formed to a certain extent, the service life of the optical axis will be affected. The same is true for cold plastic deformation layer. When the workpiece surface is extruded, it is bound to deform and increase with the increase of grinding feed.
