Mazak Corp.’s QRX-50MSY CNC turning center is designed to provide rapid, versatile performance for high-volume production of small, intricate parts in a compact machine. The QRX-50MSY combines milling capability, a second turning spindle and Y-axis functionality for small parts such as EV input shafts, mid-shafts, valve fittings and other components exceeding 2" in diameter.
The QRX-50MSY is the latest adaptation of Mazak’s HQR Series two-turret/two-spindle CNC turning center with similar milling and Y-axis functions. It boasts a 15% smaller footprint with floor dimensions of 119.3" (3,030 mm) × 86.6" (2,200 mm) while maintaining throughput and reduced cycle times. Additionally, the QRX-50MSY’s modular design uses common machine components such as identical left and right spindles, upper and lower turrets, and upper and lower carrier drives. This modular nature helps keep machine costs down to maximize a manufacturer’s return on investment when producing small parts.
The QRX-50MSY features a maximum bar diameter capacity of 2.0" (50 mm) with a 6" (152 mm) diameter chuck and incorporates a slant-bed design. The main and second spindles use 20-hp (15 kW) motors that provide maximum speeds of 6,000 rpm. The 12-station/24-tool position upper and lower turrets feature 7.0-hp (5.3 kW) rotary tool spindles that offer maximum speeds of 6,000 rpm.
The machine’s toolholding utilizes a basic metric tooling (BMT) 45 interface for fast, precise tool changes and optimized performance. The interface uses static and driven tools and supports a wide range of toolholder types, including radial, axial and angular toolholders. The BMT 45 interface enables tools to be rotated 180 degrees for use on second operations, eliminating the need for tool changes between operations.
The QRX-50MSY is equipped with a work unloader over the top of the second spindle that shops can equip with a gripper or parts bucket to remove parts from the machine. An auto parts catcher mounted on the lower turret catches parts at the second spindle head or positioned beneath the main spindle, and it can also accommodate end-of-bar remnants.
The machine comes standard with the Mazatrol SmoothG CNC that includes Mazatrol conversational programming as well as EIA-ISO G-code programming capabilities. The control provides ease of operation with its 19" touch screen and 3D model-based graphical user interface for intuitive operation similar to smartphones and tablets. It also incorporates a wide variety of advanced programming functions for high-speed, high-accuracy machining performance.
