How to obtain hollow aluminum tubes such as drawings by rolling?
Then what is the shape of the mold? I am a beginner don't understand, but also trouble you to explain in detail the design such as a casting, a concise said hollow workpiece with the same shape, and then put the water into the aluminum molding, after cooling the mold parts get separated! If the workpiece is relatively small, the aluminum bar will be directly turned, drilling is also OK, big can also be a waste of materials!
Use mould to be able to do, do not know size, thickness, cannot decide what craft!
The length can be rolled, but must be the middle groove turning or milling.Chasing the answerThe pipe wall is thin and the requirement of accuracy is not high. The rough car will do. The precision requirement is high, so the numerical control car will be needed!AskBut how thin is the lathe?Chasing the answerIn copper, three claw clamping, after the car, and then cut to the required length.
