Adjustable Spot Cooler Aids Polycarbonate Machining

Our customer had a job to produce a product called a "bake and brine injector" used in the food industry. This product is made from lexan polycarbonate. They first milled 1/2" slots into the lexan and then drilled two 3/4" holes into two of the slots. The drilling process resulted in a large burr which was melted and stuck to the lexan. A secondary hand cutting and filing operation was needed to remove the burr. They outfitted the drill with an EXAIR Model 3925 Adjustable Spot Cooler which kept the drill cool enough to allow the lexan to form chips and not melt onto the slots. The Adjustable Spot Cooler has eliminated the need for the secondary operation, sped up production time and decreased cost.
