WILLIS MACHINERY & TOOLS 3500 SERIES HORIZONTAL MACHINING CENTER

Technical Description

The Willis Machinery & Tools 3500 Series Horizontal Machining Center is a heavy-duty turning center engineered for high-volume production work. This two-axis machine features a single main spindle with a 30-inch chuck diameter capable of accommodating workpieces up to 35 inches in turning diameter and 800 inches in maximum turning length. The spindle operates at 630 RPM with 40 horsepower, with an optional 450 RPM configuration available for enhanced torque on demanding applications. The machine accommodates a maximum swing of 53 inches over the bed, enabling efficient machining of large cylindrical components. With 17 inches of X-axis travel and standard 60-inch Z-axis travel (expandable to 800 inches optionally), this center provides flexibility for various workpiece geometries. The slide-type primary tool carrier enables single simultaneous cutting operations, optimizing tool life and surface finish quality. Built with robust flat-bed construction typical of Willis Machinery's design philosophy, this horizontal machining center combines power and precision for production environments requiring consistent performance on repetitive turning operations. The machine's generous swing capacity and extended turning length make it particularly suited for manufacturing shafts, spindles, and other elongated cylindrical components requiring precision finishing. Its moderate spindle speeds prioritize torque and thermal stability, ensuring reliable operation during sustained production runs while maintaining dimensional accuracy throughout extended machining cycles.
