A new solution to an old problem. Heat build up on dry machining operations reduces tool life and machining rates. The Cold Gun Aircoolant System produces a stream of clean, cold air at 50°F (28°C) below supply air temperature. 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 coolants cannot be used.
The Cold Gun is also an alternative to expensive mist systems. It eliminates the costs associated with the purchase and disposal of cutting fluids and worker related health problems from breathing airborne coolants or slipping on wet shop floors.
EXAIR offers two types, the Cold Gun and the High Power Cold Gun. The High Power Cold Gun blows twice the amount of cold air as the Cold Gun which doubles the cooling capacity. They come standard with either a Single Point or a Dual Point Hose Kit with a cone and flat nozzle. All systems come with a magnetic base and a filter separator. The magnetic base makes this device simple to attach to your machine and start using.
In trying to cut over-all costs, companies are reviewing process flows throughout their plant. A CO2 cartridge manufacturer was following that same strategy. They wanted to move the silk-screening process that marked the outside of the cartridges to a different location. Currently, the operators would have to pick up bins to move them about 50 feet (15 meters) to the packaging area. They currently were using blower-type vacuum systems in other parts of their process to move the cartridges through different stages. But, the bulkiness and noise level of the blower system made them have to find an alternative way; so, they contacted EXAIR.
For their process, they would start with a steel cap. The metal caps would run through a series of different forms where round punches would “redraw” the metal into a final diameter and thickness. Once it is finished through this process, it would look like a test tube. The metal tubes would have the ends heated and pressed with a set of different dies to create the “neck” region. The “neck” section would be cut and lathe to make a sealing edge. The cylinders would then go through a washing and drying system to clean. Once dried, they would travel to the filling station where the cylinders would be partly filled with liquid CO2, and then capped. The bare steel cylinders would move through a zinc-coating process for protection and appearance. The filled cartridges would then be inspected by quality control prior to screen printing on the outer diameter. The finished CO2 cartridges had an outer diameter of ¾” (19mm) (reference photo below). Once they are printed, the shipping staff would carry them to their department for packing.
The process flow change for this company was to move the silk-screening process about 50 feet (15 meters) from the current position. With an EXAIR Air Operated Conveyor or Line Vac™, the QC department can transfer the cartridges to the screen printer near the packaging department. This would stop the needless handling of the filled bins between the printing station and the packaging station. Not only did this speed up packaging, but it also ergonomically helped the operators from lifting and carrying.
For the material, distance, and size; I recommended the model 152125 1 ¼” Heavy Duty Line Vac Kit. This Line Vac is made from a hardened alloy material which makes them resistant to abrasion and wear. The throat diameter has a clearance of 1” (25mm) which is enough to carry the ¾” (19mm) diameter cartridges. With a kit, it will also include a filter, regulator and a bracket. The filter will help keep the Line Vac and the cylinders clean. The regulator will allow for flexibility in conveyance rates, distances, and speeds. The bracket helps to mount the Line Vac to a sturdy base for support. With the small footprint and compact design, it was easy to set up and use as a simple conveyor.
After installation, the Production Manager was amazed by the simplicity of the design and the ease of operation. He could also reduce maintenance cost without having to change intake filters, check bearings, monitor electrical controls, and replace any failed motors within the blower-type system. The EXAIR Line Vacs do not have any moving parts to wear; so, they are reliable and long-lasting. Overall, as compared to the blower-type systems; the cost, set-up, and operation were greatly improved with the EXAIR Line Vac. They were so happy in meeting the criteria above; the Production Manager mentioned that he would be replacing their existing blower systems when they fail. And as mentioned above with all the transfers to the different stations, there would be many spots for the EXAIR Line Vac to be used.
If you need to convey materials like cartridges, steel shot or abrasive products, the Heavy Duty Line Vac could be a blessing for you. Not only can they transfer material safely and quickly, but they also will ergonomically help in saving the backs and knees of your operators. How can this get any better? Until the end of October 2020, we are running a promotional ad for our U.S. and Canadian customers. You will receive a 2” Flat Super Air Nozzle, a $72.00 value, free with qualified purchases online. If you would like to discuss any of your conveying application, please contact an Application Engineer at EXAIR. We may have a solution for you.
Many machining companies like to use coolant to flood their parts for drilling and milling operations. But what if there was an alternative way? EXAIR has an interesting technique by using cold air instead of coolant. This would help save time by eliminating cleaning and drying of parts as well as reducing coolant waste. EXAIR calls this product our Cold Gun Aircoolant System™.
The Cold Gun Aircoolant System uses a Vortex Tube to produce a cold air stream at 50oF (28oC) below supply air temperature. Heat is one of the major causes for dulling and premature failures for tools, and by blowing cold air, it will reduce the heat buildup in tools while also removing the chips from the surface. The EXAIR Cold Guns are very compact, portable, and easy to use. Just attach compressed air to the unit, and it will produce cold air. Since they do not have any moving parts, Freon, or electricity to operate, it is maintenance-free and long-lasting. And, EXAIR offers a 5 year “Built To Last” warranty against defects in workmanship and materials. These systems will extend tool life, improve tolerance control, and increase production rates by replacing coolant during milling, cutting, and drilling operations.
The benefits of using the Cold Gun Aircoolant System extends beyond reducing tool wear, finishing with dry parts, and surface smearing. It can be used in applications where liquid coolant cannot be used. This would include wood products, MDF, and plastics. As insulators, cutting tools will get extremely hot as the material will not remove any heat like with metal chips. Thus, machining can soften, gall, or burn the surface of the material; allowing only slow speeds for operations. The cold air from the Cold Gun can keep the tools sharp and the materials hard and firm. With plastic materials, this is very beneficial as it will keep the plastic rigid for tight tolerance machining. If burnishing or scoring is occurring, the Cold Gun Aircoolant Systems can help to improve the surface finish of your product. Other applications would include surface grinders, laser cutters, hot melt setting, and band saws. The Cold Gun Aircoolant Systems are a low-cost solution that can do a lot of great things to improve processes.
EXAIR offers two types, the Cold Gun and the High Power Cold Gun. The High Power Cold Gun blows twice the amount of cold air as the Cold Gun which doubles the cooling capacity. They come standard with either a Single Point or a Dual Point Hose Kit with a cone and flat nozzle. All systems come with a magnetic base and a filter separator. The magnetic base makes this device simple to attach to your machine and start using. The four models that EXAIR stocks are in the photo above.
