The strength of graphite rods is very good, but the strength of carbon rods generally cannot be used so far, so it is more necessary to consider high-strength rubber or photosensitive resin instead of graphite rods. When I work for my masters, I often use this thing as insulation - you must know that they usually work on high-strength graphite rods.

As a student of mechanical design, I would like to say that rubber rods with the same structure as metal rods are purely useless. Why do you have to use rubber rods instead of metal rods? And there is something called a graphite electrode.

It's not impossible. It's just to increase the difficulty. The first thing to do is to make the interconnecting rod a kind of whole, which may take up the same space as the shaft. Secondly, the shaft and the bearing need to be integrated and welded together, so the base can't be done. If a smaller base is needed, it must be precise and durable, and it must be usable. Also, poor processing or incorrect operation is a fatal shortcoming.

If it is processed, such as the one in a cylinder, isn't it just a wooden stick? Isn't it just a metal rod that cuts iron like mud? I don't know why there are graphite rods.

Use it~ The last time I went with my classmates to play with hand-ground graphite sticks, they all said I was witty~

First of all, according to the characteristics of the material, the stress of most carbon rods will be greater than that of graphite rods during heat treatment, after all, the surface oxidation process is too fast. It is difficult to keep the surface smooth for a long time after heat treatment, so you must pay attention when making it by hand. There is no big problem with aluminum rods. And why use titanium alloy to make carbon rods? Because the hardness of titanium alloy itself is not high, it has good retention. As for the shield mentioned by the subject, I think it should be impossible. Of course, we can make more carbon rods with high machinability. A surface retaining layer of wood or something can act as a weld cap.
