MAZAK QTN 550MY HORIZONTAL MACHINING CENTER

Technical Description

The MAZAK QTN 550MY is a multi-tasking CNC turning center engineered for heavy-duty machining of large workpieces in energy and heavy equipment industries. This machine delivers 80 horsepower with a maximum spindle speed of 1,000 RPM (750 RPM optional) and accommodates a 24-inch chuck with a 46.33-inch maximum swing diameter and 35.7-inch turning capacity. The spindle features a 10.7-inch maximum bar diameter capacity and 120-inch maximum turning length, providing versatility for extended workpieces. Equipped with a 12-position turret featuring live tooling and Y-axis capabilities, the QTN 550MY performs DONE IN ONE® processing by combining turning, off-centerline milling, drilling, and specialty threading operations in single setups. The machine offers four-axis control with 22.75-inch X-axis travel, full Y-axis construction, and 120.87-inch Z-axis travel (expandable to 164.67 inches), delivering 787 inches-per-minute rapid traverse rates across all axes. The 10-horsepower rotary tool operates at 4,000 RPM with capacity for 12 rotary tools, enabling simultaneous multi-tasking functionality. This rigid construction handles high cutting forces while the turret supports one simultaneous cutting tool. An optional long boring bar tailstock configuration enables deep-hole boring depths to 46 inches, making this machine ideal for complex part completion requiring minimal setup changes and maximum production efficiency.
