Quick Turn 550MY CNC Turning Center

Mazak Corp.'s Quick Turn 550MY CNC turning center with multitasking combines advanced technology, productivity and value to deliver exceptional performance for shops large and small. As an MY configuration machine, the Quick Turn 550MY features milling capabilities and Y-axis functionality along with a standard through-hole chuck package to process a wide range of medium or larger-diameter parts in single setups. For large-diameter pipe or tubular applications, the Quick Turn 550MY can be equipped with an optional front and rear air chuck package.

The Quick Turn 550MY utilizes high-output integral spindle/motors to increase mass in the headstock and reduce spindle vibration for optimal high-accuracy machining. In addition to its standard 2,000-rpm, 50-hp (37 kW) spindle, the Quick Turn 550MY can accommodate 60-hp (45 kW) spindles with speeds of 1,000 rpm and 1,800 rpm for
spindle bores of 10.8" (275 mm) and 7.28" (185 mm), respectively.

Sporting a 12-position, direct-drive turret that eliminates the use of belts for improved part surface finishes and reduced maintenance, the Quick Turn 550MY can accept both VDI and bolt-on tooling and now comes standard with a 20-hp (7.5 kW), 4,000-rpm spindle. The machine’s headstock has an optional 18" main chuck mounted on an
optional 60-hp (45 kW), 2,000-rpm integral spindle motor for heavy-duty metal removal. For further process versatility, Y-axis off-centerline machining capabilities feature Mazak’s special high-gain servo-control turret/feed axis motion. The machine’s fully CNC programmable tailstock delivers simple, precise and automatic control of the Z-axis
directional movement and thrust force settings, while linear roller guides and rigid machine construction provide positioning accuracy two times higher than the equivalent ISO standard.

The Quick Turn 550MY also features a new Mazak Smooth Tool Eye. It is an airactuated system that will allow parts to remain in the chuck, even when using larger 18” and 21” chucks, during measuring procedures.

With Mazak’s Mazatrol SmoothG CNC, the Quick Turn 550MY gives shops the flexibility of both EIA/ISO programming and Mazatrol conversational programming to quickly and easily generate programs for fast changeovers or high-production part applications. The controls also feature advanced hardware and software functions that help ensure high productivity and performance accuracy. For increased user friendliness, a new door design allows the machine’s CNC panel to travel the full Z-axis length of the machine. The panel also pivots 180 degrees, depending on machine
operator height as well as swivels.

Related Glossary Terms

  • chuck


    Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • conversational programming

    conversational programming

    Method for using plain English to produce G-code file without knowing G-code in order to program CNC machines.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • milling


    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • through-hole


    Hole or cavity cut in a solid shape that connects with other holes or extends all the way through the workpiece.

  • turning


    Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
