Swing Lathes

 

 
Overview
Clausing Large Swing Heavy-Duty Lathes are designed to provide optimum performance, heavy stock removal while providing the versatility required by a large range of industries such as: 
• general purpose machine shops 
• mining industry 
• paper mills 
• 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
