The SOUTHWESTERN INDUSTRIES TRAK K2 is a highly versatile CNC knee mill designed for toolroom machining, prototyping, maintenance work, and short-run production. Manufactured by Southwestern Industries, Inc. under the well-known TRAK product line, the K2 combines traditional manual milling capability with the power of ProtoTRAK conversational CNC programming. The 2006 model remains one of the most popular used CNC knee mills because it is easy to operate, economical to maintain, and ideal for shops that need flexibility rather than full production automation.
The 2006 TRAK K2 typically features a 9 x 49 inch table, approximately 33 inches of X-axis travel, 12 inches of Y-axis travel, and 16 inches of knee (Z) travel with an additional 5 inches of quill travel. Most machines are equipped with a variable-speed R8 spindle capable of up to 4,200 RPM and powered by a 3 hp motor. Common controls include the ProtoTRAK SMX, Edge, or AGE series, all of which allow operators to create CNC programs directly from dimensions without the need for CAM software. Machines often include power drawbars, coolant systems, and electronic handwheels for manual and CNC operation.
The TRAK K2 is widely used in machine shops, maintenance departments, educational facilities, and R&D labs. Typical applications include repair parts, brackets, fixtures, tooling components, and prototype parts. Its ability to switch seamlessly between manual and CNC modes makes it especially valuable for one-off jobs and small batches.
The 2006 SOUTHWESTERN INDUSTRIES TRAK K2 remains an excellent investment because it offers intuitive programming, proven reliability, and outstanding versatility in a compact and affordable package.

WHY BUY USED SOUTHWESTERN INDUSTRIES TRAK K2
Purchasing a used 2006 TRAK K2 is an excellent way to add CNC capability to a shop without the cost and complexity of a full machining center. The ProtoTRAK control allows operators to program directly from dimensions, which significantly reduces setup time and makes the machine ideal for maintenance work, prototypes, and one-off parts.
Because the machine retains traditional knee mill functionality, operators can use it manually for quick tasks or switch to CNC mode for repeatable machining. Many used machines include valuable accessories such as power drawbars, coolant systems, and upgraded controls.
Buyers should inspect spindle bearings, way wear, ball screws, and the condition of the ProtoTRAK control. Machines with updated software and documented maintenance generally provide the best value.
For shops seeking a dependable, easy-to-use CNC milling solution, the SOUTHWESTERN INDUSTRIES TRAK K2 remains one of the most practical and cost-effective choices available.
