Manufactured by Southwestern Industries, Inc., the SPORT B3 combines the simplicity of conversational programming with the productivity of CNC automation. Built under the TRAK product line, the SPORT B3 is widely used in toolrooms, maintenance departments, educational facilities, and small production environments where flexibility and ease of use are essential.

The SPORT B3 typically features approximately 31 inches of X-axis travel, 16 inches of Y-axis travel, and 23.75 inches of Z-axis travel, along with a large 50 x 10 inch table. Machines are commonly equipped with a 40-taper spindle, spindle speeds up to 6,000 RPM, and a spindle motor ranging from 7.5 to 10 hp depending on configuration. Many machines include the TRAK CNC control with the company’s renowned ProtoTRAK conversational programming software, allowing operators to quickly create programs without extensive CAM experience. Automatic tool changers, power drawbars, and electronic handwheels are common options.

The SOUTHWESTERN INDUSTRIES SPORT B3 is widely used for fixture plates, prototype components, repair parts, tooling, and low-volume production work. Its bed-mill construction provides excellent rigidity, while the conversational control significantly reduces setup and programming time. Operators can machine parts directly from dimensions, making the machine ideal for job shops and maintenance departments that handle varied, short-run work.

The SPORT B3 remains an excellent investment because it offers the flexibility of manual machining, the repeatability of CNC, and the intuitive programming environment that has made ProtoTRAK one of the most popular controls in the toolroom market.
