Overview
The Mazak QT-PRIMOS is a series of compact two-axis turning centers built around a built-in motor spindle and an 8 position drum turret. Mazak's model list for the series names one machine, the QT-PRIMOS 100 SG, and a buyer should take dimensions and capacities from that model's own table. The figures on this page are listed series values and should be confirmed for a specific machine.
What Mazak says about the series is mostly about floor space and loading. The turret is servo motor driven with non-lift indexing. Daily maintenance is done from the front and rear, and the lubrication oil tank sits at the front, so machines can be installed side by side. Two loaders are offered: a Quick Loader that occupies the same floor space as the standard machine, aimed at mass production of a small variety of parts, and a Gantry Loader for a larger variety, with pallets stacked to 13.78 in and an optional turn-over unit. The control is MAZATROL SmoothEz with a touch screen.
The listed table shows a 6 in chuck, a maximum workpiece diameter of 180 mm (7.09 in) and a turning length of 200 mm (7.87 in), with a spindle listed at 6,000 RPM and 11 kW (15 hp). Not every listed value agrees with the QT-PRIMOS 100, which has a 5,000 rpm spindle and Ø1 in (25 mm) bar capacity where this table lists 42 mm (1.65 in).

Strengths & Limitations
Strengths
- 8 position drum turret, servo motor driven with non-lift indexing
- Maintenance from the front and rear only, so machines can stand side by side
- Quick Loader automation within the same floor space as the standard machine
- MAZATROL SmoothEz control with touch screen operation
Limitations
- Listed envelope is small: 180 mm (7.09 in) workpiece diameter and 200 mm (7.87 in) turning length
- Eight turret positions limit how many operations fit in one setup
- Listed spindle speed and bar capacity differ from the QT-PRIMOS 100 model, so the series figures need confirming

Frequently Asked Questions
01
Mazak's model list for the series names the QT-PRIMOS 100 SG. The QT-PRIMOS 100 has a 6 in chuck, a 5,000 rpm spindle, 8 tools and a turning envelope of Ø7 in (178 mm) by 8 in (203 mm).
02
Mazak describes two systems. The Quick Loader is for mass production of a small variety of products and needs no more floor space than the standard machine. The Gantry Loader is for a large variety of products: material and finished workpieces are loaded on pallets up to a height of 13.78 in, and a turn-over unit can be attached as an option.
03
Mazak states that no maintenance is required on the left and right sides. The areas for daily maintenance are accessible from the front and rear, and the lubrication oil tank is at the front of the machine, which is what allows machines to be installed next to each other.
04
The listed figures are a 6 in chuck, 180 mm (7.09 in) maximum workpiece diameter, 200 mm (7.87 in) turning length, X travel of 130 mm (5.12 in), Z travel of 230 mm (9.06 in) and an 8-position drum turret taking 20 mm x 20 mm tool shanks. Confirm them against the table of the specific model before relying on them.
