What happens to the precision shaft at high temperature?

In order to avoid the above phenomena, the piston rod must have sufficient strength and stiffness, and light weight. However, under the influence of high temperature, the strength of the piston rod material will inevitably decrease, the thermal expansion of the piston will increase, and the normal clearance between the piston and the cylinder wall will be destroyed, and then a series of adverse reactions will appear. Cutting tools are bound to be used in the manufacturing process of linear optical axis, piston rod and other workpieces, but it is not expected that there are strict requirements for the selection of cutting tools. After all, the material of the workpiece is relatively special, in order to ensure the cutting performance of the tool, we must meet the basic conditions.
For different purposes, the corresponding types of cutting tools are also different, such as in the milling of hexagonal prism, should choose carbide sleeve face milling cutter; grinding cylindrical and taper, should choose white steel and jade parallel grinding wheel; turning threads when using the screw turning tool, in order to achieve good processing results. Precision axis
In fact, it is better to finish the piston rod before plating, because the higher the finish, the better the quality of the chromium layer. In addition, it is necessary to check the size of the plating parts, machining surface conditions, and then according to the thickness of the coating to accurately calculate the plating time to ensure the plating effect.
