Machining NASCAR Parts with a CNC Router | JR Motorsports & ShopSabre

In this high-speed customer spotlight, we head to Mooresville, North Carolina, to visit the fabrication shop at JR Motorsports. The NASCAR Xfinity Series race team breaks down how they use a ShopSabre CNC router to keep up with the intense demand of rebuilding four to six race cars every single week.

The head of fabrication explains how transitioning from manual part-making to CNC automation has completely transformed their workflow. He shares how the machine turned a messy, 30-minute manual cutting job into a flawless 5-minute process, and how they use the CNC to perfectly countersink splitter pans to maintain flat, aerodynamic performance on the track.

Whether you are looking to scale your own auto fabrication shop or want to know how race teams instantly adapt to last-minute NASCAR rule changes without outsourcing rush jobs, this video proves why a ShopSabre CNC is the ultimate competitive edge.
