Watching this video brought some questions to mind. http://video.google.com/videoplay?docid=-3839076222492953620
How do they get the work piece to move in the Z direction while turning? The work piece must be clamped at all times in order to maintain the part index. The bar stock must have a fairly accurate OD. How accurate can the parts be if there is slop between the bar stock to allow for a slip fit and OD variation? How long of a bar can they run? How is the live tooling powered? There doesn't seem to to be enough space for a motor at each live tool spindle. A gear train would have slop and some of the live tools seem to be able to index. How long does it take to pay off a loan for one of these machines? -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
