Takamaz XYT-51

The Takamaz XYT-51 is a bar-fed turning center with a main spindle, a sub-spindle, a Y axis and two tool groups, sized around a bar capacity of 51 mm (2.0 in). Its long strokes stand out: Z1 travel is 500 mm (19.7 in), Z2 travel is also 500 mm (19.7 in), and the A-axis travel is 550 mm (21.7 in).

The axis list reads X1 162.5 mm (6.4 in), Z1 500 mm (19.7 in), Y +/- 35 mm (1.38 in), then X2 170 mm (6.7 in) and Z2 500 mm (19.7 in). The table does not say what carries the second X/Z group. Ask Takamaz whether it is a second tool post or the sub-spindle's own movement, because only a second tool post lets two tools cut at the same time and shorten the cycle on complex bar parts. Rapids are X 18 m/min, Z 30 m/min and Y 12 m/min, and the 30 m/min Z rate matters over a 500 mm stroke.

The turret is listed as a 12-station Turret with 24st., and the live tool rows give 12 tools at 4,000 rpm with capacity for drill Ø13 mm and tap M12. That is a step up from the M8 tap of the smaller XY-120 Plus, whose Z1 stroke is 330 mm and whose main spindle bar capacity is φ42 mm (φ51 mm option). The XYT-51 gives the larger bar as standard and the longer stroke on both sides.

Several rows of the published table carry two sets of values side by side: the spindle speed row gives 5,000 rpm and Max. 4,000, the turret row names both BMT45 and BMT55, and the footprint is given as 2,988 × 2,163 and 3,000 × 2,163 mm (W × L). Confirm which figure applies to the XYT-51 and to which spindle before comparing it with other machines. The control is listed as TAKAMAZ & FANUC 32i-B.
