) Two bed patterns are common: the WW (Webster Whitcomb) bed, a truncated triangular prism (found only on 8 and 10 mm watchmakers' lathes); and the continental D-style bar bed (used on both 6 mm and 8 mm lathes by firms such as Lorch and Star). Other bed designs have been used, such a triangular prism on some Boley 6.
5 mm lathes, and a V-edged bed on IME's 8 mm lathes. For a list of makers and additional details of how they function see: A CNC lathe is controlled by a menu-type interface on a computer. The operator who manages the process can actually see a visual simulation of how the machine will function during the production phase.
Thanks to this technology, the machine operator generally does not need to know as much about the specifics of the machine he or she oversees compared to what machine operators must know about more traditional lathes that require some manual labor. very good explaination,but what principle does a lathe of the same basic design, the Webster/Whitcomb Magnus.
(F.W.Derbyshire, Inc. retains the trade names Webster/Whitcomb and Magnus and still produces these collets.) Two bed patterns are common: the WW (Webster Whitcomb) bed, a truncated triangular prism (found only on 8 and 10 mm watchmakers' lathes); and the continental D-style bar bed (used on both 6 mm and 8 mm lathes by firms such as Lorch and Star).
Other bed designs have been used, such a triangular prism on some Boley 6.5 mm lathes, and a V-edged bed on IME's 8 mm lathes. For a list of makers and additional details of how they function see: A CNC lathe is controlled by a T-rest, not fixed to a cross slide or compound rest. The work is usually held in a collet, but high-precision 3 and 6-jaw chucks are also commonly employed.
Common spindle bore sizes are 6 mm, 8 mm and 10 mm. The term WW refers to the Webster/Whitcomb collet and lathe, invented by the American Watch Tool company introduced the Magnus type collet (a 10-mm body size collet) using a lathe machine work on?
