    MACHINE CONSTRUCTION 
    Rigid on-piece Meehanite cast iron bed construction on the Viper series of CNC turning centers provides the ultimate in machine tool accuracy and reliability. A 45 ° slant bed design with integrated torque tube ribbing, gives the Viper exceptional stability in heavy-duty cutting operations and an optimal chip removal system. Cutting reaction forces are minimized resulting in a high degree of precision. Both the X and Z axis on the Viper series of CNC turning centers are supported by oversized hardened and ground box-type ways with exceptionally fast rapid rates of 787 in/min in the X-axis and 945 in/min in the Z axis.

    HEADSTOCK & SPINDLE 
    An unrivaled fast, rigid and accurate spindle, the Viper spindle is housed in a cast iron headstock that is designed to easily handle the spindle drive capacity. The Viper's headstock has thermal deformation prevention design for more accuracy. Relying on the latest technology provided by Fanuc, the Viper uses Fanuc's brush-less spindle motor with a dual winding to achieve its high and low torque ranges. This spindle design allows for flexibility for different feeds and speeds needed when cutting a variety of materials. The Viper's spindle generates excellent surface finishes and extraordinary metal removal rates. High accuracy P4 grade angular contact thrust spindle bearings ensure precision turning during long-term operations. With a robust 4.3” thru hole spindle diameter spindle bearing, the Viper series of CNC turning centers provides the rigidity for this accurate spindle.

    AXES DRIVE SYSTEM 
    These drives provide the axis with maximum radial torque through extremely accurate, zero backlash, and large diameter pretension double-nut ballscrews. Since the feed screws require high speed feed and reverse capability, the VT Series employs extremely accurate single pitch ballscrews. These ballscrews are preloaded and supported at both ends bearing blocks, thus eliminating ballscrew whipping, and tensional twisting, while increasing rigidity and ensuring smooth accelerations and deceleration rates.
    Coupled between each axis drive motor and ballscrew is a mechanical torque limiting tensional clutch. When the torque load of the drive system exceeds the mechanical value, the clutch disengages the drive motor, protecting the integrity of the axis drive system.

    STATIC TURRET 
    A large, rigid, high speed, precision ground turret indexing in 0.5 seconds from station to station, as well as utilizing shortest path indexing, makes the Viper's turret excellent for production machining. The turret is designed with 12 stations that accept ?” OD tooling, 1.0” ID tooling and allows for minimal tool interference.

    DYNAMIC TURRET (OPTIONAL) 
    In addition to standard chucking and turning operations, unit handles secondary machining including milling, drilling and rigid tapping. Enables both horizontal and vertical machining.

    TOOL PRE-SETTER (OPTIONAL) 
    With its tool pre-setter system, the Viper is an ideal machine for both short-run and high production environments. The Viper's tool pre-setting system assists in reducing set-up time, changing tools and insures accurate measurement of tool offsets. The tool pre-setter allows for various checkpoints throughout the program to obtain optimal part accuracy and finish. These tool offsets are quickly and accurately measured by the tool pre-setter probe system.

    BALL SCREWS 
    Powerful, robust THK ball screws are what generate slide-way movement in both axes in the Viper series of CNC turning centers. Using only the finest quality parts, both the X and Z-axes are driven by an ultra-precise ball screw that is pre-loaded and double anchored for optimum drive conditions .

    PROGRAMMABLE TAILSTOCK 
    The highly rigid tailstock is match ground to the headstock-mounting surface, establishing absolute alignment between the two. The heavy-duty tailstock is a two-piece modular design that alleviates machine induced taper. Its center of gravity is in the horizontal plane, thus eliminating any machine induced taper into the work piece. Tailstock body is positioned by a drive bar, which engages with the carriage. The drive bar and tailstock clamping are programmable. Being programmable enables quick setups.

    CHIP REMOVAL 
    Proper chip removal is essential in maximizing metal removing conditions. The Viper's 45 ° bed construction prevents chips from accumulating on the slides. With its standard rollout the front style chip pan, the Viper CNC turning center allows for easy chip removal from the machine. An optional chip conveyor is available with all Viper series CNC turning centers.

    TAKE CONTROL 
    It is an ultra-compact controller with network capability. Featuring a CNC printed circuit board integrated with a liquid crystal display enables Ethernet communication functions. 

    High speed PMC process sequence control is 2.5 times faster than FANUC's previous controllers. Programming capacity has been greatly expanded for sequence control of peripheral equipment enabling monitoring and editing functions to be incorporated on the CNC unit. 

    Advanced preview control allows looking ahead at multiple parts of the part program and reduces machining errors in corners and arcs, which in turns results in high speed and high precision machining. CRT standard is a 9” monochrome; a 10.4” color LCD featuring high brightness and width vision is optional. Should failure occur, causes and recovery are displayed on the CNC display screen, in turn enabling a more rapid recovery.
