Cleaning with an Air Wipe

I received a call about a blow-off operation. The customer had an automated machine that would thread, cut, and stack a 1” (25mm) diameter pipe. The operation was ran by a CNC lathe that would thread both ends and cut the pipe to length. An automatic arm would feed the next piece of pipe into the lathe, and at the same time, push the finished piece of pipe through the chuck. Another robot arm would grab the finished pipe and stack it. The reason for his call was that he was losing coolant from his CNC machine. He used the coolant for the cutting and threading operations. When the CNC lathe would cut the pipe to length, the coolant would leak into the center of the pipe. As it was being brought out of the machine, coolant would leak onto the floor. It was a safety issue as well as the cost to replace the coolant. He wanted to keep as much coolant inside his machine during his operation.

The customer believed that he would need two types of products to solve his problem. He was looking at a Standard Air Wipe to remove the coolant from the outside of the pipe, and a Super Air Nozzle to remove the coolant from inside the pipe. In getting more details about the application, we were able to determine that we could use just the Standard Air Wipe. With the design of the EXAIR Air Wipes, a 30 degree angle of compressed air is directed toward the center in a 360 degree air pattern, just like a cone. This design allowed us to address both problems. The primary function of the Air Wipe would be to blow the coolant from the outside of the pipe. As it passed through the chuck to the robot arm for stacking, the Air Wipe would blow the coolant off the pipe and back into the machine. The second function of the Air Wipe was to keep the coolant from leaking through the center of the pipe. With the finished pipe being stacked, the conical air flow would blow into the open cavity of the chuck and right into the center of the pipe. As the new pipe was being cut, the Air Wipe would increase the pressure inside the pipe, keeping the coolant from seeping into the center.

I recommended model 2482, 2” (51mm) Standard Air Wipe Kit. The kit included the Air Wipe, shim set, filter separator, and pressure regulator. This would insure long lasting operations with the ability to control the amount of compressed air being used. Here at EXAIR, we enjoy solving problems. I was able to correct his problem with one product item, instead of two or more. It is not just about the amount of sales, but about helping our customer in the most effective way.
