• power utilities 
• ship repair and the oil field industry. 
All machines are tested to the most stringent accuracy and test cuts are made before shipping...
 
Construction

Electrical Equipment

    Siemens electrics, 230 3ph, 60Hz
    The electrical enclosure is sealed and the disconnect switch has a door interlock 
    Low 24 volt controls are used for added safety 
    All terminal blocks are shielded for added protection 

    Fused power supply and all motors have overload protection

Gear Box

    All gears are hardened to RC-45 and ground
    A wide range of feeds as well as Inch, Metric, Module and Diametric Pitch threads can be cut by simply changing the levers 
    Forced lubrication and a built-in safety clutch protects the universal gear box

Headstock and Spindle

    Extra heavy-duty, ribbed, thick wall casting provides superior rigidity for deep cuts
    All gears and spline shafts are tooled from high-quality steel, harden and ground and lubricated by an auto lube system 
    The spindle is supported by precision taper roller bearings 
    High torque 18 speed spindle is driven by a single speed drive motor and equipped with an electro-magnetic spindle brake

Carriage and apron

    Constructed of heavy-duty ribbed Meehanite casting for maximum rigidity
    The cross slideways are hardened and ground 
    The saddle slideways are covered with Turcite B to reduce friction 
    The cross-slide has a ballscrew 

    The gears in the apron are nitrate hardened 

    An independent lubricating system provides automatic lubrication to bedways and cross-slides 

    Asafety interlock is provided for automatic or rapid traverse of the carriage and cross-slide

Bed
    Extra wide, one piece bed from bedways to floor, is constructed of Meehanite casting for maximum rigidity
    The prestressed bedways are induction heat treated and ground for ware resistance 
    Up to 315" long in a one piece casting

Tailstock

    The tailstock quill is hardened to RC-45 and ground
    Motorized tailstock 
    Equipped with a 2-speed feed
