Controlink Systems LLC was founded in 1998 in Lawrenceburg, Indiana, with a singular mission: develop software solutions that make CNC machine communication fast, easy, and reliable. Over the past 25-plus years, we have grown from a focused DNC software developer into a comprehensive products-based engineering services company serving manufacturers across the United States. We became a proud member of the NI Partner Network in 2000—the same year The Timken Company recognized our technology as innovative—and have never stopped pushing the boundaries of what shop-floor software can do. From small screw machine shops in the Midwest to national laboratories and Fortune 500 manufacturers, we build Controlinks that keep American manufacturing moving.
DNC (Direct Numerical Control) software manages the transfer of CNC program files between a computer and CNC machine tool controls. Shops need it to eliminate manual USB or paper tape transfers, ensure machinists always run the latest engineering-approved programs, reduce scrap caused by outdated files, and keep operators focused at their machines rather than walking to a central PC.
