Mazak QTE-100MSY

The Mazak QTE-100MSY is the QTE-100 with everything on it: Mazak's model list gives its configuration as Milling, Second Spindle, Y-axis. The main spindle has a 6 in chuck and the second spindle a 5 in chuck, each running to 6,000 rpm, with a 4,500 rpm milling spindle in the turret and 4 in (102 mm) of Y travel.

The two chucks are only one size apart. A part gripped in the 6 in chuck for the first operation will usually still fit the 5 in chuck for the second, which is not always true of machines where the second spindle is much smaller than the main. Matching 6,000 rpm limits mean the hand-over and the back-side turning do not have to slow down.

W-axis travel is 23 in (584 mm), a little more than the 22 in (559 mm) maximum turning length, so the second spindle can come to the part instead of the part having to be short. The rest of the envelope is a Ø13 in (330 mm) maximum turning diameter, a Ø27 in (686 mm) swing, Ø2 in (51 mm) of bar capacity, 8 in (203 mm) of X and 24 in (610 mm) of Z on the 500U bed. All of it runs from 12 tools.

What the table leaves out is power. There are no motor or torque rows for the main spindle, the second spindle or the milling spindle. Mazak describes the QTE series spindle as a built-in motor designed for high torque at low speed, without a number for this model.
