A machining apparatus has a frame having an upright front wall and two vertical guides on the front wall carrying respective spindle units displaceable on the guides and each having a workpiece holder rotatable about a respective vertical axis and vertically shiftable between a respective upper machining station and a respective lower pick-up/drop-off station. A horizontal guide on the front wall carries a tool turret carrying a tool and shiftable along the horizontal guide between one position aligned with the axis of one of the spindles and another position aligned with the axis of the other of the spindles. A conveyor transports unmachined workpieces into the lower stations and machined workpieces out of the lower stations. Respective actuators shift the spindle units vertically along the respective axis between the lower stations and the upper stations. |
