represents a huge annual savings for our company, without sacrifi cing any safety considerations for our workforce.”


Fabrication Process


JAC understands the fabrication process for putting holes into aluminum, whether for roof mounting, rivet placement, or trim assembly. Often, the angle of the drill must be oriented to the surface of the workpiece, rather than in a typical X-Y planar arrangement. Here again, the fl ex shaft design of the Suhner drills pays big dividends for the machine designers at JAC, as it permits them to position the drilling mechanisms in various confi gurations and tighter proximities. This allows the required accuracies, secondary counterbore operations or other processing steps to occur. After working on nearly 500 machine builds at JAC, Mike Traylor said he’s been im- pressed with the fl ex shaft drill and its adaptability on a wide variety of applications. “On one rail set for a Ford vehicle and another for a Toyota vehicle, the old way would have involved one operator per- forming all the drilling, one step at a time,” he said. “Today, we have up to 11 drills and a cutoff operation, all performed at once. The savings in setup time alone are off the chart.” He


cites another job where the output was previously 1200 sets per day and is currently 1200 per hour. Not all of the drilling here is done with fl ex shaft models,


however. On several dedicated machining operations, various Suhner motor-mounted drills are utilized, including a specially designed system for sawing. JAC’s Senior Launch Manager Alberto Blanco said, “We need to hold ± 0.1–0.2-mm tolerances on the drilling and ±0.5 mm on our cutoff lengths for our customers, so the Suhner equipment capability has been very favorable in helping us de- liver our value proposition to customers.” Traylor added that the drills are used virtually non-stop, so wear is inevitable, further noting the availability of Suhner rebuild kits, including O-rings and seals, makes maintenance much easier for his team. “With the support we get from Suhner, we know Mike and his team can make it happen, every day, creating and maintaining the machines that get the job done for our cus- tomers,” said Jeff Cavalier, the JAC engineering & facilities manager. “That’s a nice feeling.”
