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.

EXAIR Chip Vac Removes Swarf and Keeps the Machining Center Running

The word of the day is “swarf”. Swarf is fine chips or filings of stone, metal or other material produced by a machining operation.

A company had four automatic profile cutting machines to cut aluminum stock.  They contacted me for help to improve their operation.  Each machine had a cleated belt conveyor to remove the swarf (or chips) from the cutting process.  Because the swarf was small in size, the chips could get around the edge of the belt and affect the conveying system.  Two of the four conveyors failed, and they wanted to find a better option to remove the swarf and keep the machines running.  They sent me a photo of the type and size of the swarf that was thwarting their conveying system.

EXAIR receives many calls about applications similar to this. I suggested the model 6193 Chip Vac System.  This assembly will fit onto a standard open-top 55 gallon drum which has a much smaller footprint than the conveying system.  The 0.1 micron filter allows for the air to escape and keep the fine particles inside the drum.  For this customer, once the drum was filled with aluminum chips, it was easy to rotate in an empty drum, sending the full drum of material to recycling.  The vacuum generator has no moving parts which makes it quiet, maintenance free, and long lasting.  It also creates a high vacuum level which was very useful when they attached it near the chip collection area.  The Chip Vac System was easy to install and it was very beneficial in keeping the machining area clean and running.
