- X/Z travel240 / 400 mm
GT8-300Y is retained with an 8 in chuck, Ø340 mm disc turning, Ø50 mm bar passage and 300 mm maximum machining length subject to configuration. Its X/Z travels are 240/400 mm and main spindle bore is Ø76 mm. Bore and bar passage are separate limits, and the machining-length condition is retained.
The Y table states +50/−16 mm at spindle centre. Its +50/−50 mm range is conditional on a 90° tool centre 57–123 mm from spindle centre in X. The latter cannot be presented as unrestricted symmetric Y motion. X/Z/Y rapids are 30/30/10 m/min in that order, rather than an X/Y/Z sequence.
The table lists a servo tailstock as optional and spindle speed up to 5,000 rpm as configuration-dependent. Its external dimensions are 3,760 × 2,050 × 2,030 mm. Published axis repeat positioning and travel do not describe finished-part accuracy or clearance through every holder orientation. This is a technical record with factory-specific transaction services unavailable.
