The Cold Gun Aircoolant System with a dual point hose kit produces a stream of clean, cold air at 50°F (28°C) below supply air temperature. Systems include the Cold Gun, flexible dual point hose assembly and manual drain filter separator. Available in standard or high power versions. Operation is quiet and there are no moving parts to wear out. It will remove heat to prolong tool life and increase productivity on machining operations when liquid coolant cannot be used. Because it uses vortex cooling, the Cold Gun is also an alternative to expensive mist systems by eliminating the costs associated with the purchase and disposal of cutting fluids as well as worker related health problems from breathing airborne coolants or slipping on wet floors.

How the Cold Gun Works

How the Cold Gun  Works

The standard Cold Gun and High Power Cold Gun incorporate a vortex tube to convert an ordinary supply of compressed air (1) into two low pressure streams, one hot and one cold. Secondary air is drawn in (2). The Cold Gun's hot airstream is muffled and discharged through the hot air exhaust (3). The cold air (4) is muffled and discharged through the flexible hose (5), which directs it to the point of use. Easy mounting and portability are provided through the use of an attached magnetic base (6).

Cold Gun Applications

Tool Grinding and Model 5215 Cold Gun
Model 5215 Cold Gun System
Tool Grinding

Cold air eliminates heat cracking of carbide and tool edge burning during grinding and sharpening operations. Increased tool life between regrinds is the result.

Milling & Drilling

Fly cutters up to 460mm in diameter have been cooled with the Cold Gun. Dissipating heat with cold air extends tool life, increases speeds and feeds, and improves finishes.

Chill Roll

Cooling a roll with 20°F (-7°C) air keeps the material on the surface from bunching up, jamming or tearing. The metal surface transfers the cold temperature to the product.

Model 5230 High Power Cold Gun quickly cools a hot part.

Laser Cutting

Cold air cools a laser cut part so it can be handled seconds later. The High Power Cold Gun has twice the cooling capacity of the standard Cold Gun, cooling the part in less time.

Tooling costs a lot of money to replace. That’s only part of the problem. As the tools wear out, you can expect:

  • Slowed production and downtime to change out the tooling
  • Poor tolerances and decreased dimensional accuracy due to increased temperature
  • Increased cutting force is required (generates more heat and uses more electricity)

If you could just make the tooling last longer, you’d not only cut the tool cost but could increase profits by reducing scrapped parts and downtime.

A long term study on the effect of refrigerated air on tool wear in wood machining was conducted at the Forestry Products Department of Purdue University by Ms. Judith Gisip. The project was under the direction of Dr. Rado Gazo (department professor) and Harold Stewart (professor at North Carolina State University with 35 years in wood machining research). Wood is brutal on tooling. In metalworking, most of the heat goes away with the machined chip. Wood is an excellent insulator and doesn’t conduct the heat away, which keeps it all there at the tool. Temperatures can exceed 1472°F (800°C)!

The extensive tests at Purdue were conducted in a 70°F climate controlled room. They tested (4) 1/2" (12.7mm) two-flute cutters on a CNC router at 16,000 rpm. (22) sheets of 3/4" thick MDF (medium density fiberboard) were fed one at a time, cutting away 1/4" (6mm) depth of cut on each pass. Power consumption of the CNC was recorded (current draw increases as the tool starts to dull). When finished, the surface of the tools was examined using a scanning electron microscope. Machining with the Cold Gun’s 20°F air reduced tool wear by over 21% compared to the results with no cooling.

How Much Can You Save?

  • A 1/2" two flute router bit for wood is approximately $67.00.
  • The 21% reduction in tool wear when using a Cold Gun is $67x0.21=$14.07 savings per bit.
  • If you use (1) router bit per working day, the savings is $14.07x5 working days = $70.35 per week / $3,658 per year for one bit!
