Adjustable Spot Cooler Keeps Band Saw Blade Cool

We run into interesting applications that require cooling all the time. Here’s an example of a spot cooling application for a tire cutting application that used a FLIR camera to show the heat generated within the band saw blade.

The customer is a world supplier of tires for various vehicles from ATV to construction use. And they have a need to cut tires up for quality control testing as well as R&D purposes. They were looking for a low cost and efficient way to cool the blade without using liquid coolant or water as those methods require implementation of waste handling schemes that this customer did not want to deal with. So, they came to EXAIR as they knew we specialized in cold air cooling products. Specifically, they had interest in model 3925 (Dual Point, Adjustable Spot Cooler System). The dual point hose kit would allow for even cooling on both sides of the band saw blade. After discussing their application details, we agreed that model 3925 would be the best offering we could make to the customer. As we have a band saw in our workshop, I located some rubber material that we had with similar properties to a tire and made some quick tests to determine that in fact, model 3925 allowed for only a modest 5°C rise in temperature. The customer was quite satisfied at our test result and purchased 4 units for their band saws.

Super Ion Air Knife Cleans Product Exiting Cutting Application

Yesterday, I had a customer call in to discuss his application regarding chip and debris removal from his product. The customer described his process of cutting lenses for light fixtures that their company manufactures. While he was explaining the application and the problem, I was building a picture of it in my mind.  To help in the understanding the customer e-mailed me a photo of the application so I could really see the mess he was trying to deal with.

Once I saw the photo, I could see that my understanding was off just a little concerning the automatic nature of the cutting machine. Instead of having an operator pulling the cut lenses off the machine and blow them down, he wanted the lenses to come out already cut and blown free of static, debris and dust.

Once I saw the photo above, I could see that the flat nature of the target product was a perfect fit for the Super Ion Air Knife Kit model 111218. That unit fit the customer’s machine guard just right in order to accommodate the various widths of material that he processed through the cutting function. He set the Super Ion Air Knife up to blow down at a 45° angle opposite the travel of the material. In effect, he was blowing back toward the saw blade which had a vacuum system attached. Not only was the material able to exit cleaned, but it kept the processing area cleaner as well as the chips and other debris were deflected back to where the vacuum system could pull them in.

The customer’s improvement in productivity actually doubled as an aid in their housekeeping within the processing area.
