USED MAZAK QT-PRIMOS 50 SG

The Mazak QT-PRIMOS 50 SG is a compact, high-speed CNC turning center designed specifically for small part, high-volume production where speed, accuracy, and floor space efficiency are critical. It is the smallest model in the QT-PRIMOS SG series and is engineered around Mazak’s rigid cast-iron structure combined with a built-in motor spindle. This spindle design eliminates belts and gears, reducing vibration, improving thermal stability, and delivering consistent cutting performance even during long production cycles. The result is improved surface finish quality, higher roundness accuracy, and reduced maintenance requirements.

The machine is equipped with a 5-inch chuck and is optimized for small components with a maximum machining diameter of approximately 180 mm and a machining length of around 204 mm. This makes it ideal for precision parts such as automotive connectors, medical components, small shafts, and general engineering fittings produced in high quantities. Despite its compact size, it maintains strong rigidity, allowing stable cutting at high spindle speeds up to around 5000 rpm.

A key feature of the QT-PRIMOS 50 SG is its high-speed 8-position servo-driven turret, capable of indexing in approximately 0.2 seconds. This fast tool change capability significantly reduces non-cutting time, making it highly efficient for repetitive production cycles. The turret supports standard turning tools and boring bars, enabling flexible machining within a compact footprint.

The machine is controlled by Mazak’s MAZATROL SmoothEz system, which offers conversational programming, touchscreen navigation, and simulation-based setup. This reduces programming time and allows operators to quickly switch between jobs, improving productivity in job shop and batch production environments.

Automation compatibility is another strength, with support for compact bar feeders and gantry loaders, enabling continuous unattended production.

Overall, the QT-PRIMOS 50 SG is widely used in industries requiring fast, repeatable, and cost-efficient machining of small components, where minimizing cycle time per part is more important than machining large or complex geometries.

WHY BUY USED MAZAK QT-PRIMOS 50 SG

Buying a used Mazak QT-PRIMOS 50 SG is an excellent option for manufacturers seeking a compact, high-speed CNC lathe at a significantly reduced investment cost. Since this machine is designed for high-volume production, its value in the used market remains strong, especially for shops focused on small precision components and repeatable batch work.

One of the most important factors when evaluating a used unit is cutting hours. Machines with low usage (typically under 5,000–10,000 hours) generally retain excellent spindle accuracy, smooth axis movement, and fast turret indexing. These machines are ideal for precision production where tight tolerances and consistent cycle times are required. Mid-hour machines (10,000–25,000 hours) are commonly found in production environments and still perform reliably for general machining applications, provided proper maintenance has been carried out. High-hour machines (25,000+ hours) may require inspection of spindle bearings, turret wear, and ball screw condition, but can still be used effectively for less critical or rough machining tasks.

A major advantage of buying used is cost savings. Since most CNC machines depreciate heavily in the first years of ownership, used buyers gain access to Mazak’s high-speed automation and rigid machining capability at a fraction of the original cost. This improves return on investment and allows smaller shops to compete in high-volume production markets.

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

Overall, the QT-PRIMOS 50 SG remains a strong choice in the used market due to its simplicity, durability, and high-speed performance, making it ideal for continuous production of small, precision-machined parts.

HOW MUCH DOES A USED MAZAK QT-PRIMOS 50 SG COST?

The price of a used Mazak QT-PRIMOS 50 SG depends on manufacturing year, machine condition, cutting hours, and installed options. As the smallest model in the PRIMOS series, it is typically more affordable than larger SG variants, but still maintains strong demand due to its high-speed production capability and compact footprint.

For newer machines manufactured between 2015 and 2025, prices generally range from approximately $40,000 to $75,000. These machines usually have low cutting hours, modern Mazatrol SmoothEz controls, and may include automation systems such as bar feeders, chip conveyors, or compact loading systems. Units at the higher end of this range are often near-new condition and capable of continuous production with minimal downtime.

For mid-generation machines built between 2005 and 2015, typical prices fall between $25,000 and $45,000. 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 environments. While still reliable, buyers should carefully inspect spindle condition, turret indexing accuracy, and axis wear to ensure continued precision.

Older machines manufactured before 2005 are usually priced between $10,000 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 refurbishment, ball screw repair, or control system upgrades. However, they can still be useful for rough machining or non-critical production tasks where extreme precision is not required.

Cutting hours are a key factor in valuation because they directly affect spindle life, machining accuracy, and cycle stability. Lower-hour machines maintain better precision and faster cycle times, while higher-hour machines are more affordable but may require increased maintenance and show reduced accuracy under continuous production loads.

Overall, the QT-PRIMOS 50 SG holds strong value in the used market due to its efficiency, compact design, and suitability for high-volume production of small precision components.
