Abstract
A multitasking workpiece machining apparatus includes a pair of workpiece support devices supporting an elongated workpiece, first and second headstocks at positions outside of the workpiece support devices. The second headstock is capable of moving closer to and apart from the first headstock. Each workpiece support device respectively includes a travel drive device traveling between the first and second headstocks. A numerical control unit controls travel of each workpiece support device by synchronously controlling each travel drive device.
