The Mazak QRX-50MY SG is a compact, high-efficiency CNC turning center designed for mass production of small to medium-sized shaft-type components. It belongs to Mazak’s QRX series, which emphasizes space-saving design, multi-turret productivity, and automation-ready performance. The machine features a dual-turret (upper and lower) configuration, enabling simultaneous machining operations that significantly reduce cycle times compared to single-turret machines.
Unlike MSY variants, the QRX-50MY SG uses a single spindle with tailstock, making it ideal for shaft work rather than dual-spindle bar-fed applications. It offers a bar capacity of approximately 52 mm, an 8-inch chuck, and a maximum machining diameter of around 245 mm with machining length up to 552 mm. The addition of Y-axis capability allows for off-center milling operations, enabling complete part machining in a single setup.
The machine is equipped with Mazatrol SmoothG control, providing intuitive conversational programming alongside G-code compatibility. Automation options such as bar feeders, workpiece unloaders, and parts catchers allow for long-term unattended operation. Overall, the QRX-50MY SG is widely used in automotive, general engineering, and high-volume manufacturing environments where efficiency, precision, and compact footprint are essential.

WHY BUY USED MAZAK QRX-50MY SG
Buying a used Mazak QRX-50MY SG is a cost-effective way to access advanced CNC turning technology while maintaining high productivity. One of the main advantages is the significant reduction in upfront investment compared to a new machine, while still benefiting from Mazak’s reputation for durability and long service life. These machines are designed for continuous production and can deliver reliable performance even after years of use when properly maintained.
A key benefit of the QRX-50MY SG is its dual-turret configuration, which enables simultaneous machining and balanced cutting. This dramatically reduces cycle times and improves throughput, making it ideal for high-volume production environments. Additionally, the Y-axis capability allows for more complex machining operations to be completed in a single setup, reducing the need for secondary processes.
Used machines are typically available for immediate delivery, helping manufacturers avoid long lead times associated with new equipment purchases. Many pre-owned units also come equipped with automation systems such as bar feeders and unloaders, adding further value. Cutting time is one of the most important factors when evaluating a used machine; lower spindle hours generally indicate better remaining life, accuracy, and reliability. Overall, buying used allows businesses to expand production capacity while controlling capital expenditure.
HOW MUCH DOES A USED MAZAK QRX-50MY SGCOST?
The cost of a used Mazak QRX-50MY SG depends on manufacturing year, configuration, condition, and especially cutting time. Since this model is part of Mazak’s newer QRX series introduced around 2025, there are no machines available from before 2000 or even 2000–2010 for this specific model. However, comparable older Mazak dual-turret machines may range from $30,000 to $100,000 depending on condition and usage.
For actual QRX-50MY SG machines from 2025 onward, used pricing typically ranges between $180,000 and $320,000 or more, depending on features such as Y-axis capability, automation integration, and tooling packages. Machines with low cutting time command premium pricing because they retain higher accuracy, reliability, and longer service life.
Cutting time plays a critical role in valuation. A machine with minimal spindle hours can perform close to new condition and justify a higher price, while machines with higher usage may be more affordable but could require maintenance sooner. Because the QRX-50MY SG is a newly launched, high-efficiency production machine, it holds strong resale value in the market. Buyers should carefully evaluate usage history alongside features and condition to determine the true cost and long-term value of the machine.
