ROLL LATHES
Roll lathes are cold finishing turning machines which shape an object using hardened steel, carbide, ceramic or other types of tooling. Roll lathes rotate the workpiece while the tool is moved across the work piece to cut out a specific shape or surface. There are a variety of different types of roll lathes with the most common being the engine roll lathe. Engine roll lathes are used to machine the circumference or face of the workpiece. Other lathe types include boring, facing, roll, and right angle. Traditional roll lathes are equipped with a cross slide or compound which holds the toolholder and turning tool. The cross slide can be traversed the length of the lathe bed, perpendicular to the lathe bed or both motions simultaneously. The lathe compound is driven by an Acme screw at various, operator selected speeds. This ability to traverse at a selected speed provides the roll lathe operator with the capability to machine a thread into the workpiece in addition to machining specific shapes. Roll lathes can be equipped with CNC (computer numerical control) for extreme accuracy. Modern CNC roll lathes are often classified as machining centers because they can perform other machining operations in addition to turning. Roll lathes are generally sized by their swing and distance between centers. Swing is the overall diameter of the work piece that can be rotated in the machine over the roll lathe ways. A second critical swing dimension is the maximum diameter that can be rotated over the cross slide. The distance between centers is the maximum length of the opening between the head stock and the movable tail stock. Contact Casey Equipment for a quote on used roll lathes for sale.
