USED MAZAK QT-PRIMOS 100 SG

The Mazak QT-PRIMOS 100 SG is a compact, high-speed CNC turning center designed for precision machining in small to medium-sized components. It is part of Mazak’s QT-PRIMOS series, which emphasizes space efficiency, fast cycle times, and high productivity in a small footprint. The machine is built with a rigid cast structure and an integrated motor spindle system, eliminating belts and gears. This design reduces vibration, improves thermal stability, and enhances surface finish quality while maintaining consistent cutting performance over long production runs.

The QT-PRIMOS 100 SG typically features a 6-inch chuck size and is optimized for parts with a maximum machining diameter of around 180 mm and machining length of approximately 200 mm. This makes it ideal for high-volume production of small precision parts such as automotive components, medical parts, and general engineering fittings. The spindle is capable of speeds up to 5000 rpm, allowing efficient cutting across a wide range of materials including aluminum, mild steel, and alloy steels.

A key feature of this machine is its 8-position servo-driven drum turret, which provides fast indexing (around 0.2 seconds), enabling reduced cycle times and improved productivity. The turret supports both turning tools and boring bars, making it suitable for flexible operations in tight production environments.

The machine is controlled by the MAZATROL SmoothEz system, which offers conversational programming, touchscreen operation, and simulation capabilities. This reduces setup time and allows operators to quickly switch between jobs, making it highly effective for job shops and batch production environments.

Automation readiness is another advantage, with compatibility for compact loaders and gantry systems that support lights-out manufacturing. Its small footprint allows multiple machines to be installed side-by-side, maximizing shop floor efficiency.

Overall, the QT-PRIMOS 100 SG is widely used in industries requiring fast, repeatable, and cost-efficient machining of small components while maintaining Mazak’s reputation for accuracy and reliability.

WHY BUY USED MAZAK QT-PRIMOS 100 SG

Buying a used Mazak QT-PRIMOS 100 SG is a smart choice for manufacturers who need a compact, high-speed CNC lathe at a lower investment cost. This machine is designed for productivity, and even used units retain strong performance due to its rigid cast structure and integrated motor spindle system, which reduces mechanical wear compared to belt-driven machines.

One of the most important factors when evaluating a used QT-PRIMOS 100 SG is cutting hours. Machines with low hours (under 5,000–10,000) generally maintain excellent spindle accuracy, stable axis movement, and consistent turret indexing. These machines are ideal for precision batch production. Mid-hour machines (10,000–25,000 hours) are commonly found in production environments and still perform reliably for general machining, though inspection of spindle bearings, turret wear, and axis backlash is recommended. High-hour machines (25,000+ hours) may require maintenance such as spindle refurbishment or ball screw adjustment but can still be used effectively for less critical or roughing applications.

A major advantage of buying used is cost savings. Since most depreciation occurs early in a machine’s life, buyers can access advanced CNC automation and high-speed production capability at a fraction of the original price. This improves return on investment, especially for small and medium-sized job shops handling repetitive production runs.

Mazak’s Mazatrol SmoothEz control system also adds long-term value, as it is widely supported and easy to operate. This reduces training time and allows quicker integration into existing production setups. Many used machines also come with useful accessories such as chip conveyors or bar feeders, further improving productivity without additional investment.

Overall, the QT-PRIMOS 100 SG remains a reliable choice in the used market because of its durability, fast cycle capability, and low maintenance design, making it ideal for high-volume precision manufacturing.

HOW MUCH DOES A USED MAZAK QT-PRIMOS 100 SG COST?

The price of a used Mazak QT-PRIMOS 100 SG depends on manufacturing year, machine condition, cutting hours, and installed options. Since it is a compact production-oriented lathe, it remains in demand in the used CNC market, especially for high-volume small part manufacturing.

For newer machines manufactured between 2015 and 2025, prices typically range from approximately $45,000 to $85,000. These machines usually have lower cutting hours, modern Mazatrol SmoothEz controls, and may include automation options such as bar feeders or chip conveyors. Units at the higher end of this range are often in near-new condition with minimal wear and strong production capability.

For mid-generation machines built between 2005 and 2015, typical prices fall between $25,000 and $50,000. These machines generally have moderate cutting hours in the range of 10,000 to 25,000 hours and are widely used in job shops and production lines. While still reliable, buyers should inspect spindle condition, turret indexing accuracy, and axis wear before purchase to ensure continued precision.

Older machines manufactured before 2005 are usually priced between $12,000 and $25,000 depending on condition and usage history. These units often exceed 25,000–40,000 cutting hours and may require maintenance such as spindle replacement, ball screw servicing, or control upgrades. However, they can still be useful for rough machining or non-critical production tasks.

Cutting hours play a major role in valuation. Lower-hour machines retain better precision, faster cycle stability, and higher resale value. High-hour machines are cheaper but may require more maintenance and can show reduced accuracy under continuous load.

Overall, the QT-PRIMOS 100 SG is considered a strong entry-level production lathe in the Mazak lineup, and its used market pricing remains stable due to its reliability, compact footprint, and suitability for high-volume, repetitive machining applications.
