Overview
The Mazak QT-PRIMOS is Yamazaki Mazak's entry-level CNC turning center, designed to bring Mazak build quality to shops with smaller budgets or simpler turning requirements. Available in three sizes (50, 100, and 150), the QT-PRIMOS is a straight 2-axis lathe focused on basic turning rather than multi-axis complexity.
The QT-PRIMOS 100 SG runs a 6-inch chuck with a max turning diameter of 180 mm (7.09 in) and 200 mm (7.87 in) of turning length. The 8-position drum turret indexes in 0.2 seconds with 20 mm tool shanks. It is a small, fast machine built for cranking out simple turned parts.
The QT-PRIMOS 50 SG is the smallest in the lineup, targeting very small precision parts. The QT-PRIMOS 150 SG steps up in capacity for slightly larger work. All three share the same compact design philosophy and basic turning focus.
The control options include MAZATROL SmoothEz or the MAZAK FZ control. The FZ is an even more simplified control aimed at operators who just need to load programs and press cycle start. SmoothEz adds conversational programming for shops that want to program at the machine.
The QT-PRIMOS competes with entry-level machines from Haas (ST-10), Doosan (Lynx 2100), and budget imports. It costs more than the cheapest options on the market but delivers Mazak's engineering and support infrastructure. For shops that want a reliable, compact lathe for simple turned parts without the complexity and cost of live tooling and multi-axis capability, the QT-PRIMOS delivers exactly what is needed and nothing more.

Strengths & Limitations
Strengths
- Lowest entry price in the Mazak turning lineup
- 0.2-second turret indexing keeps cycle times short
- Compact footprint takes minimal floor space
- 6,000 RPM spindle speed for small-diameter aluminum and brass
- Choice of SmoothEz or simplified FZ control
- Built-in motor spindle even at this price point
Limitations
- 8-position turret limits tool capacity with no 12 or 16-position option
- No milling, Y-axis, or sub-spindle configurations; strictly 2-axis
- 180 mm max turning diameter and 200 mm length severely limit part size
- 20 mm tool shanks are smaller than industry-standard 25 mm
- 11 kW spindle power restricts heavy stock removal

Frequently Asked Questions
01
Pricing starts around $45,000 for the QT-PRIMOS 50 and runs up to $75,000 for the QT-PRIMOS 150.
02
No. It is a straight 2-axis lathe with no live tooling options. For milling, look at the QTE or QT-Ez.
03
A simplified CNC control for basic operation. Handles program loading and cycle execution without MAZATROL conversational programming.
04
Haas ST-10 offers larger 8-inch chuck, more capacity, and live tooling at similar or lower price. QT-PRIMOS is more compact with faster turret indexing but limited to 2-axis.
05
QT-PRIMOS 100: up to 180 mm diameter, 200 mm length. Bar work limited to 42 mm diameter.
