Vertical multi spindle automatic transfer spinner

The transfer spinner is for high volume production of poly-V-pulleys. The main characteristic of the machine are four spindles, each equipped with one working unit. A linear transfer system moves the parts from one station to the other. This machine is capable of producing all types of poly-V-pulleys at high volumes.
