The Case for the Cold Gun

Heat is an unavoidable by-product of any cutting or machining operation. Think about it: you’re creating friction on a piece of material with a fast-moving piece of harder material in order to forcibly separate pieces of the original material from its existing shape & size. No matter what, something’s going to get hot: the work piece, the tooling, or (almost always) both. If you don’t do something about it, your parts can become damaged, your tooling can become dull and brittle, and productivity will suffer.

There are ways to alleviate the problem…you can slow the speed of your tooling, but that’s hardly practical, and only marginally effective.  You can use liquid cooling…in fact, you may have to if the particulars of the operation require the lubrication you can only get from a cutting oil or liquid coolant.  But those can be messy, expensive, and the time you spend maintaining the coolant could certainly be spent better elsewhere…like, on machining your products!

The EXAIR Cold Gun Aircoolant System is a novel solution to these problems…heat related and otherwise:

  • The Cold Gun uses compressed air to produce a stream of clean, cold air at 50°F (28°C) below supply air temperature.
  • They use Vortex Tube technology…no moving parts to wear out.
Instant cold air flow with no moving parts!
  • Cold flow and temperature are preset to optimize cooling capability, and are non-adjustable to prevent freeze-up during use.
  • Eliminates the expense of both the purchase & disposal of cutting fluids.
  • Removes the potential for health problems associated with breathing mist & vapors, and the safety issue of slipping on a wet floor.

Cold Gun Aircoolant System selection is easy & straightforward…we offer a standard, and a High Power version to meet your specific needs.

Four systems to choose from, to meet most any need.

We also offer Single & Dual Point Hose Kits, to further meet the needs of your application.  Right now, you don’t have to decide up front…order a Cold Gun Aircoolant System with a Single Point Hose Kit before December 31, 2018, and we’ll throw in the Dual Point Hose Kit for free.

A Better Way To Extend Tool Life

Spring is here in the Midwest, and it’s a darn fine time to be outside doing stuff. I took the opportunity the other day to set out a few tomato plants in the pitifully small area we have in our yard that actually gets enough sunlight to be effective at promoting photosynthesis – a term my 7th Grade son picked up on in science class, and I’m hoping will prove to be more interesting…at times…than his video games.

Anyway, in order to do this Real Gardening Work, I had to get some tools out of their winter hibernation. I was pleased to recall that, last fall, I had taken extraordinary measures to clean, lubricate, repair, and properly store my small arsenal of dirt-working implements. So, I didn’t have to:

*push the hand spade’s handle back in, every time I pulled it from the dirt.
*pull the pruner blades back open every time I squeezed them closed.
*reassemble my “garden weasel” tilling tool with bailing wire.

I was able to do all of that, last fall, with glue, oil, and fasteners that I already had in my garage, so it cost me nothing but the time to do it. Which paid off the other day.

There are plenty of ways to extend the life of your tooling – but it all boils down to how you operate and maintain it.  I was able to apply the latter successfully, and I recently had the pleasure of discussing an application with a machine shop’s maintenance supervisor, about applying the former. He was interested in making operational improvements by replacing their messy mist coolant systems, and extending the life of their tooling. It was almost like he’d been reading our Cold Gun literature (full disclosure: he had.)

With four systems to choose from, we can help you get the right one for your application.

The Cold Gun Aircoolant System has proved to be a highly successful solution to both of these problems. In fact, the improvements in tool life has been documented in this detailed, long-term study by a major university’s Forestry Products Department.
