An army of CNC milling machines with multiple tool stations churn out aluminum end caps eight at a time. In a typical machine shown here, one jig of eight parts is being machined while a second jig is loaded. In two operations (one for each side of the cap) a part goes from raw stock to almost finished. A similar, five-axis milling machine is also used to fabricate the company's line of triple clamps (magnesium for the race team) and port four-stroke motocross cylinder heads.
