Since 1963, Southwestern Industries, Inc. has been an industry leader in innovative products for machinist productivity.

Our engineering, manufacturing and corporate headquarters are housed in 130,000 sq. ft. facilities in Southern California. We employ a large field organization of factory-direct sales, service and management personnel throughout North America.


All ProtoTRAK controls utilize conversational language programs as well as CAM and G-code. They are available on SWI branded TRAK mills and lathes and can be retrofitted on other manufacturers knee mills. All controls are designed and built “from scratch” at SWI 's Rancho Dominguez, CA factory headquarters. The ProtoTRAKs are among the most widely used conversational language CNCs in the world. Both the controls and machines are designed specifically to address the inefficiencies associated with one-off and small lot machining.
