How to turn a cylinder with an ordinary lathe (reward points will be added for good answers)

First, select a 45-degree cutter, an alignment cutter or an offset cutter, and process with 6 140, 620 or 6 16. This workpiece does not belong to the slender shaft.

Because of the large diameter allowance of the blank, the three-jaw chuck is used to clamp it. Clamp one end, then turn the chuck to knock it right, and then clamp it hard. Turn one end flat with a 45-degree knife, then drill the center hole, center it, roughly turn the excircle to a certain length, and then semi-finish or finish turn it to size. Cut the other end face with a knife, exit the turning tool when it is about to be cut off, and break the workpiece. If necessary, turn around and flatten the nose. If grinding is needed, center holes should be drilled at both ends. This is a relatively simple and effective method.
