As far as the cylinder piston rod itself is concerned, it is a kind of part which is relatively difficult to process, and is relatively high in terms of accuracy requirements. The cylinder piston rod is widely used in the telescopic arm of the crane, and it can be said to be a relatively part of the link. Its dimensional accuracy is IT8, and its surface roughness value is Ra0.4. Here, we have to know that because the cylinder piston rod is relatively long, its dimensional accuracy and surface quality are also very demanding, so its processing will be very difficult. However, there are also some solutions. We need to know that when the cylinder piston rod is processed, it is subjected to many common effects from cutting force, dead weight, and centrifugal force during torsion. In this way, an abnormal situation of bending and vibration will occur. It will affect many aspects such as roundness, cylindricity, dimensional accuracy, and surface roughness. In addition, during the cutting process of our cylinder piston rod, the workpiece is deformed due to the thermal elongation of the workpiece. This will easily lead to its taper, drum shape, and its twist shape and bamboo joint shape. Defects, in this case, in our cutting process, there are also many problems that we cannot predict. In fact, when it comes to this, we have also discovered that the difficulty in machining the cylinder piston rod itself is our lack of skill and craftsmanship. The words here require us to start with the processing technology. Regarding the difficulty of machining the cylinder piston rod, in addition to what we just said, we must solve the machining process problem. In fact, we also need to solve the problem of the tool material when the cylinder piston rod is processed. Furthermore, we should pay attention to the accuracy of dimensions and the surface quality of some steel materials.
