The new You Ji VMT-800 from Absolute Machine Tools Inc. is a versatile mill/turn multitasking machine well-suited for both oil and gas and aerospace manufacturing applications. This machine allows a manufacturer to perform vertical turning operations as well as five-face milling operations in one setup. This machine will increase productivity by largely decreasing machining time and avoid inaccuracies from multiple hands-on movement of the workpiece from one machine to another.

The heavy duty moving column design allows for robust turning as well as heavy milling because of heavy cast iron construction and rigid box ways. The rugged 20-hp, 50-taper, B-axis head allows for vertical/horizontal milling for true one-setup machining. The B-axis indexes 0-90 degrees in 5-degree increments. The 32-tool (60/90 optional) changer provides flexibility for complex parts manufacturing. Maximum swing diameter of the workpiece is 1,100mm (43.3”) and maximum turning height is 900mm (35.43”) allowing for large component piece manufacturing. The You Ji VMT-800 has a C-axis table for easy five-sided machining.

The VMT-800s generous axis travels are +/- 550mm (+/- 22”) in X, 1,100mm (43.3”) in Y, and 1200mm (47.2”) in Z. A 35-hp spindle motor drives the standard 32” hydraulic chuck and provides 1,500 ft,-lbs, of turning torque. Fanuc CNC controls are standard.     

Moving a workpiece from one machine to another and mastering the setup takes expertise. In today’s workforce it is tough to find skilled workers that can do this without creating tolerance errors and the potential of scrapping an expensive workpiece. The You Ji VMT-800 eliminates these issues and increases throughput and profitability.

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.

  • 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.

  • tolerance


    Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.

  • 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.
