Mazak Quick Turn

The Mazak Quick Turn series is a turning center line of 21 listed models in five sizes, numbered 100, 200, 250, 350 and 450, with chucks from 6 in to 18 in and turning lengths from 13 in (330 mm) to 80 in (2,032 mm). Every model has a built-in motor spindle, so there are no gears or belts in the drive, and linear roller guides on all axes.

The suffix says what is added to the basic lathe. On Mazak's model list a plain number is a turning machine, M adds milling, MY adds milling and a Y-axis, MS adds milling and a second spindle, and MSY has all three. The spread is uneven. The 200 and 250 sizes are listed in all five forms. The 100 size is listed only as MY, MS and MSY, and the 450 size only as plain, M and MY, so the 450 size cannot be had with a second spindle.

Three models show how the envelope steps up. The Quick Turn 100MY has a 6 in chuck at 6,000 rpm, turns Ø11 in (279 mm) by 13 in (330 mm) and has 3.94 in (100 mm) of Y. The Quick Turn 200 has an 8 in chuck at 5,000 rpm and turns Ø14 in (356 mm) by 20 in (508 mm) with 8 in (203 mm) of X and 22 in (559 mm) of Z. The Quick Turn 200MSY turns Ø15 in (381 mm) by 23 in (584 mm), with 9 in (229 mm) of X, 4 in (102 mm) of Y and 23 in (584 mm) of Z. At the far end of the series the table reaches an 18 in chuck, a 2,000 rpm spindle and 37 kW (50 HP) on a 30 min. rating; the small end starts at 11 kW (15 HP) on the same rating.

Several details are worth settling early. C-axis indexing in 0.0001° increments is standard on both spindles, while contouring is optional except on the main spindle of the M models. The NC tailstock is servo driven with thrust set in 0.1 kN increments. Scale feedback on X and Z is an option that is not offered on the 100 series. Depending on the model the drum turret is a 12 position, a 16 position or a 12 position (24 position) type, and the tool holders are bolt-on or VDI. The control is MAZATROL SmoothG, which also accepts G code.
