Florence, Kentucky, November 4, 2009 – Mazak's Slant Turn NEXUS 550M is a powerful, heavy-duty CNC turning center designed for large part turning applications such as oil field pipes, pipeline control valves, turbine wheels, aircraft and off-road parts and the production of power generating components for the aerospace, oil, gas, coal and nuclear industries. The Slant Turn NEXUS series is a renovation of Mazak's successful Slant Turn series of CNC lathes.
The STN550M's headstock features a ø 10.8" bore mounted on a 60 hp, 1,000 rpm turning spindle generates up to 5,163 ft-lbs of torque for heavy duty cutting of large workpieces. The spindle is also used as a C-axis, capable of being indexed at 0.001° increments to accurately position the part for slotting cuts and precisely drilled holes. Additionally, the C-axis spindle is a full-function CNC controlled axis for milling.
For convenient tool management, the STN550M utilizes a 12-position drum turret for rapid tool indexing. The machine is also equipped with a 10 hp, 4,000 rpm high speed milling spindle for roughing, grooving, endmilling and facemilling operations, allowing many processes to be completed in a single machine cycle. The STN550M's total travels are 18.25" in the X-axis and 129.88" in the Z-axis, with a 40.7" swing capacity and a capacity steady rest of ø 16.14”.
The machine also features an NC servo-driven tailstock to enable automated processes. The tailstock is fully programmable, driving the W-axis on its own AC servomotor and ball screw. Through the part program, the tailstock will retract to a known position and its center makes contact with the part with consistent holding pressure. Further, because of its positive independent drive system, the tailstock can be used to drill holes on a shaft centerline adding versatility to the jobs it can process.
The sixth-generation Mazatrol MATRIX NEXUS CNC simplifies multi-tasking metalworking operations on the STN550M. It offers a 12” LCD color display and the familiar QWERTY keyboard. A pointing device, acting like a mouse, and USB port for downloading programs are also at the operator’s fingertips.
Conversational part programming can be accomplished in Mazatrol language while the machine is cutting another part, or off-line in a CAD/CAM system. Once imported into Mazatrol MATRIX, a realistic 3D cycle simulation verifies the machining cycle and checks for machine interferences, greatly reducing the need for test cuts.
