"To accomplish this job, we needed some large tooling as well as sufficient horsepower and spindle speed for the rapid mate- rial removal required. Using a ½-inch radius cutter, the Feeler easily machined the plates within a short cycle time with no more than 10 percent load on the spindle," Mr. Sarro says. Another application required machining a 1.25-inch thick by 11.25-inch long by 6.75-inch wide top plate with a small radius. The program size and spindle speed were best-suited for the Feeler machine. The company was able to leave the job running for 8 hours of lights-out operation, b e c a u s e t h e F e e l e r i s s e t to a u to m a t i c a l l y power off. This reduced labor costs and increased productivity. The company says that the machine provides exceptional tolerance for smaller-part work as well. In one of its larger-production jobs, Sarro needed to produce a 6061 aluminum heat sink part measuring 5 by 1 by 1 inch. To complete the part, the company used the Feeler to run a 1 / 8 -inch Sarro needed the 23.6 inches of travel on the Feeler VMC to machine the end holes in this large aluminum plate for a support upright part. Sarro was able to leave this top plate job running 8 hours lights-out using the Feeler machine, which features an automatic power-off. 0614_MMS_better.indd 132 5/14/2014 8:49:30 AM
