Cold Gun Keeps Router Bit Cool in Sign Making Application

Customer routinely cuts letters and various other shapes out of 1/8" aluminum sheet, expanded PVC board and various other non-metal materials as needed per design of the signage they are manufacturing. They currently either machine the material dry or they use a mist lubrication system to help extend the service life of the cutters. The problem is that this adds a large amount of time to clean-up for the operators who use the machine. The material must be very clean prior to going to next step which is usually painting. By eliminating the mist coolant, the customer can eliminate the huge step of cleaning. The cold air has also proven to allow the customer to run less passes with bigger cuts which increases overall machine productivity. The customer has been using Model 5230 High Power Cold Gun System to achieve these results.
