            Hard metals present one of the most difficult challenges to machine shops, machine shop operators and machinists everywhere. While most shops are only intermittently faced with extremely hard metal turning, jobs often come along that are so difficult that they must be sub-contracted or declined.  ChilAire™ Lite CO2 units are the answer!  Economical, light and mobile, these compact systems will cool the hottest tool tip for longer tool life resulting in an superior surface finish so even the most demanding customer will be coming back for more.  

        We hope you find this information helpful and we welcome your comments.

Why use a CO2 Coolant Lubrication System?
                                                                                                                                 

 

A CO2 Coolant Lubrication System reduces machining time while providing a superior surface finish.  Turning tool steels, Inconel, Invar, Super Alloys and Stainless Steel cutting times are reduced dramatically.  Increase turning productivity with other exotic metal grades such as Hastalloy and Titanium as well as plastics and rubber parts.  Studies have shown that the ChilAire™ system will extend tool life by up to 50% and allows faster feed rates by up to 40%, in most hard turning applications.

 

BENEFITS:
Higher Feed Rates Longer Tool Life Superior Heat Removal	No Fluid Waste No Staining Better Part Finish	Portable Options Infinitely Variable Dry, Near-Dry, Wet and near-Cryogenic Cooling-Lubricating Sprays	Use any lubricant additive Less Misting & Smoking Cleaner Machining - Saves $

What is a CO2 Coolant Lubrication System?
The ChilAire Lite CO2 coolant lubrication System is a patented hard turning cooling approach using environmentally friendly carbon dioxide to eliminate flood coolant so the finished product is clean and cool to the touch.

A ChilAire™ Lite System includes: Cleaning-Coolant Spray Generator/Controller One Spray Applicator with Magnetic Flex-Mount Custom spray-through cutting tools Interface Cable for Automatic machine Control (M-Codes) Compact size and small footprint

 

A Basic System Includes:

• Spray Generator: Cooling lubricant spray generator with spray pressure regulator, coolant flow regulator, coolant primer switch, lubricant flow regulator, liquid CO2 inlet and dry compressed air inlet ports. 
• Spray Applicators: Single spray applicator with magnetic mounting base with a complete set of flexible nozzle tubes and spray nozzles.  Custom spray-through cutting tools available.
• Manual Control:  A finger-switch control is provided for manual machine control operations.
• Machine Control: Remote machine control is enabled via a front-mounted connector for cable integration with any assembly or machine tool controller (ie., PROFIBUS, G-Code).
• Lubricant Additive System: Refillable liquid reservoir, oil-level sight gage, multiple setting switch and fill and drain ports.

Technical Specifications

• Dimensions: 16"w x 9.5"h x 10.5"d
• Weight: 25 lbs.
• Coolant Supply: Liquid CO2, 20C, 832 psi (293 K, 5.7 MPa)
• Propellant Supply: Dry compressed air, 20-150 psi, 6-10 scfm (137-1000 kPa, 170-283 L/min)
• Lubricant Supply: Synthetic, Mineral, Biobased Oils, 0.1-2.0 ml/min.

Examples

Turning Carbide
ChilAire turned the part in the picture to the right in 30 minutes vic PCD insert, versus 3 hours of grinding.  

2x deeper cut at same feed rate,  10x+ tool life*, Superior finish, Substrate is at room temperature during cut. Parts typically requiring 3 hours of diamond grinding can be machined in 30 minutes with PCD inserts.

SWISS MACHINING
Titanium Medical Parts
Improved surface finish, Better tolerances, No flooded coolant.

 

Laboratory Tested Productivity

Standardized tests performed by a nationally recognized laboratory have demonstrated the ChilAire outperforms conventional flooded coolant proceses in terms of both uniform tool wear and cutting force.  Moreover, specialty tool coatings such as PCD used with the ChilAire sprays have been shown to last up to 10 times longer as compared to dry machining, with deeper cutting capability as well.

ChilAire Lite is beneficial for a variety of challenging machining operations and existing lubricants.  It improves performance in operations which are normally run dry.  Example machining processes include drilling, turning, milling, grinding and progressive stamping.  It may be integrated directly into new or existing machining equipment and processes to provide cool, clean lubrication for the most challenging a machining applications.
