Overview

The Mazak QT-PRIMOS 100 is the mid-range model in Mazak's entry-level QT-PRIMOS turning center family, designated as the QT-PRIMOS 100 SG. It delivers Mazak build quality in a compact, simple 2-axis lathe designed for high-volume production of small turned parts. The '100' designation indicates the 6-inch chuck class, positioned between the smaller PRIMOS 50 and larger PRIMOS 150.

The QT-PRIMOS 100 runs a 152 mm (6 in) chuck with a maximum turning diameter of 180 mm (7.09 in) and a maximum turning length of 200 mm (7.87 in). The built-in motor spindle delivers 11 kW (15 hp) at up to 6,000 RPM through an A2-5 spindle nose. Bar capacity is 42 mm (1.65 in), suitable for production bar feeding of small-diameter stock.

The 8-position drum turret indexes in just 0.2 seconds, keeping non-cutting time to an absolute minimum in production cycles. Tool shanks are 20 mm x 20 mm with selectable boring bar diameters of 20 mm or 25 mm. The fast turret indexing and compact design make the QT-PRIMOS 100 particularly effective for high-volume, short-cycle parts.

The QT-PRIMOS 100 offers a choice of MAZATROL SmoothEz or the simplified MAZAK FZ control. SmoothEz provides full conversational programming capability, while the FZ control is designed for operators who simply need to load programs and press cycle start. Both run on touchscreen interfaces.

The QT-PRIMOS 100 competes with the Haas ST-10, Doosan Lynx 2100, and Nakamura-Tome SC-100. It costs more than budget imports but delivers Mazak's engineering, support infrastructure, and proven reliability. For shops needing a compact, fast lathe for small turned parts without the cost and complexity of milling or multi-axis capability, the QT-PRIMOS 100 is purpose-built.

Strengths & Limitations

Strengths

0.2-second turret indexing minimizes non-cutting time for fast cycle times
6,000 RPM spindle speed enables high surface speeds on small-diameter aluminum and brass
Compact footprint takes minimal floor space in crowded shops
Built-in motor spindle even at this entry-level price point
Choice of SmoothEz conversational or simplified FZ control
Mazak reliability and support infrastructure at entry-level pricing

Limitations

8-position turret limits tool capacity for complex parts
No milling, Y-axis, or sub-spindle; strictly 2-axis turning only
180 mm max turning diameter and 200 mm length restrict part size
20 mm tool shanks are smaller than industry-standard 25 mm

Best For

High-volume production of small turned parts under 6-inch diameter Shops needing a compact, reliable CNC lathe for simple turning work Production cells cranking out short-cycle parts with fast turret indexing Training environments and technical schools needing Mazak platform experience Shops adding a secondary lathe for overflow or dedicated part families

Frequently Asked Questions

01 What does a new Mazak QT-PRIMOS 100 cost?

New pricing runs $50,000-$75,000 depending on control choice and options. The FZ control option is slightly less expensive than SmoothEz.

02 Can the QT-PRIMOS 100 do milling?

No. It is a pure 2-axis lathe with no live tooling capability. For milling, step up to the QTE-100M or QT-Ez 8M.

03 What is the MAZAK FZ control?

A simplified CNC control for basic operation. Handles program loading and cycle start without conversational programming. Best for production environments where programs are prepared offline.

04 QT-PRIMOS 100 vs QT-PRIMOS 150?

The PRIMOS 150 offers a larger chuck, more turning capacity, and more spindle power for bigger parts. The PRIMOS 100 is faster and more compact for smaller work.
