WILLIS MACHINERY & TOOLS 2260 (2280) HORIZONTAL MACHINING CENTER

Technical Description

The WILLIS MACHINERY & TOOLS 2260 (2280) Horizontal Machining Center is designed for moderate-sized machining tasks with a maximum spindle turning diameter of 15.5 inches and a turning length capacity of up to 120 inches. It features a single main spindle with a 9-inch chuck diameter and a maximum swing of 22 inches, operating at a maximum speed of 1,600 RPM and powered by a 10 HP motor. The machine supports two primary axes—X and Z—with travels of 5.25 inches and 10.5 inches, respectively, enabling precise horizontal machining operations. The primary tool carrier is a slide type accommodating one simultaneous cutting tool, which supports machining with focused tool engagement, maintaining rigidity during cutting. The horizontal machining center is suited for applications requiring moderate speed and substantial part size, emphasizing reliability and adequate power for medium-duty tasks. The configuration allows for turning operations on longer workpieces while maintaining spindle power and torque. Though it lacks multiple spindles or advanced multi-axis features found in some high-speed or multi-axis centers, it remains effective for standard horizontal machining jobs requiring up to 10 HP spindle power and restricted speed ranges typical of general-purpose machining centers.
