G-Series Vertical Machining Centers

FlexCNC introduces G-Series vertical machining centers for facemilling, helical milling, rough milling and drilling of large or long parts in a single setup. The standard edition Model 20-06 SE boasts a 20-foot by 6-foot bed to machine parts up to 20-feet in length. 

Alternately, the long open bed, coupled with the movable safety light curtain, allows multiple setups, so that while the 20-06 SE is machining one part, another can be loaded (or offloaded). This dramatically increases productivity of the machine’s uptime. The open design provides unrestricted access which makes loading and unloading easier and faster. FlexCNC machines are for machining long products like tube or pipe, and cutting keyways.

The 20-06 SE features a monoblock welded steel frame with high rigidity and a T-slot machine bed. Spindle taper of CT 40, at 6,000 rpm, with a maximum torque capability of 74 ft/lbs. (with 18-hp upgrade). This product line features maximum travel rate of 1,200 in/min along the X-axis, 1,000 in/min along the Y-axis and 165 in/min along the Z-axis.  Z-Axis travel is 19.5” max. Spindle nose to table distance from 5.5” to 25.0”.

Standard unit runs on 480V and includes mobile light-curtain safety barriers, frame with chip conveyor and T-slotted table, flood coolant pump and tank, and automatic tool calibrator. The 12” color touch screen is water-resistant and durable enough to provide years of service. Oversized double hung precision linear guideways ensure smooth and precise movement on all axes. All moving parts are self-lubricating on all axes. A programmable servomotor drives the spindle, while a 10-compartment automatic toolchanger ensures capacity for virtually any application.

Control on the FlexCNC is simple yet powerful, with conversational and ISO G- and M-code programming for versatile 3-axis CNC machining along with an optional 4th axis. It is equipped with a color touch screen control, 40 GB of program storage and 50 programmable zero points. Programs can be loaded through USB or through and ethernet connection. Extensive training is provided, both in-plant and on-site.

Built in the Wapakoneta, Ohio, factory, the G-series 20-06 SE sells for $258,995. Leadtime for these standard machines is 12-16 weeks. Delivery, installation, training and two-year warranty available for $9,500. In addition to standard models, FlexCNC can customize a machine to suit specific parameters, including length and width, raised gantry, open machine bed, and double fourth axis. 

Related Glossary Terms

  • M-code programming

    M-code programming

    Miscellaneous, or auxiliary, functions constitute on/off type commands. Used to control actions such as starting and stopping of motors, turning coolant on and off, changing tools, and clamping and unclamping workpieces.

  • automatic toolchanger

    automatic toolchanger

    Mechanism typically included in a machining center that, on the appropriate command, removes one cutting tool from the spindle nose and replaces it with another. The changer restores the used tool to the magazine and selects and withdraws the next desired tool from the storage magazine. The changer is controlled by a set of prerecorded/predetermined instructions associated with the part(s) to be produced.

  • centers


    Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

  • 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.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • facemilling


    Form of milling that produces a flat surface generally at right angles to the rotating axis of a cutter having teeth or inserts both on its periphery and on its end face.

  • 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.

  • toolchanger


    Carriage or drum attached to a machining center that holds tools until needed; when a tool is needed, the toolchanger inserts the tool into the machine spindle. See automatic toolchanger.
