Precision axis - the problem of guiding accuracy should be taken into account in the selection of straight optical axis.

Edit:admin   Browse:992  Date:2017-03-16

The directional accuracy of the linear optical axis is related to many factors, including the material, diameter, performance and so on. In order to ensure a higher directional accuracy, it is necessary to select the hard and durable materials, high frequency heat treatment, accurate external diameter size, true roundness, true straightness and surface treatment strictly. Precision shafts are used in many fields, such as automotive parts, office automation parts, household electrical appliances parts, power tools parts and so on.
First, the blanking is realized, and the length of the optical axis is determined, and then the length is cut. Then the material is roughly straightened, and the outer circle is formed. Then the surface quenching, low temperature tempering and other heat treatment processes are carried out to improve the performance of the product. In general, if the mechanical load center of gravity and the screw center overlap state, should choose a smaller diameter of straight optical axis. If the stroke is relatively small, or the screw and shaft fixed installation, or the screw and shaft parallel to the case of good, small diameter products will be more consistent. But if the opposite is the case, the chosen optical axis should be thicker.

Previous:Long shaft - if there is a plug bouncing problem in use, it will bounce more
Next:Attention should be paid to the optical axis positioning of stainless steel, which should be carried out according to the requirements in the process of processing and using.
