To provide a spinning apparatus which can perform a teaching operation without using a hydraulic mechanism without a fear of damage due to an overload even when a roller tool interferes with a forming die.
The roller tool is driven by a linear motor which generates a thrust force according to a driving current. In the teaching operation, an operator manually operates the roller tool via an operation lever to form a workpiece, and operation commands in this case are stored in a memory. After that time, the same shape as before can be repeatedly formed by giving the stored operation commands to the linear motor. Therefore, the teaching operation of spinning work can be performed without the fear of damage due to the overload even when the roller tool interferes with the forming die. Further, nearly the same movement of the roller tool as that in the teaching operation can be exactly reproduced even if there is a disturbance, such as friction. In addition, the teaching data can be stored with a small memory capacity even if the teaching operation takes a long time, and a working time can be shorten in reproducing the teaching data.
