Effects of cryogenic treatment and refrigerated air on tool wear when machining medium density fiberboard

Cooling of cutting tools with liquid coolants and lubricants is impractical when machining dry wood or wood composites. This study examines the combined effect of cryogenic tool treatment and using refrigerated air for cooling tools on reducing tool wear. A total of four, double-flute, solid, tungsten carbide router bits were used to machine medium density fiberboard with a CNC router.

New approach of cryogenically treating tools -Purdue University researcher

According to Robert Gazo, Purdue University researcher has discovered a way to save energy and money by cryogenically freezing tools for 24 hrs before use. Gazo along with other researchers has tried approaches to cool the tools, which include blowing refrigerated air onto the tools and cryogenically freezing the tools, as well as a combination of both. Professor Robert Gazo and other researcher tem has concluded that freezing tools for 24 hours before use allowed them to stay sharp longer, reduce repair and replacement costs.

According to John Koucky, president of 300 Below, Inc, the process changes the microstructure of the tools by lowering the temperature to 300 degrees below zero, then bringing back to ambient temperature.

Cryogenic motorsports engine treatment

Cryogenic treatment of both new engine and used engine by metal exposed to extreme cold temperatures. Engine is stripped down completely and indvidual components are treated through use of Nitrogen, this process allows enough gas into the chamber to cool the load to the desired point on the cooling profile.

Cryotech treatment saves money and time

Cryotech process is proven as an effective treatment for tools, musical instruments, golf clubs, auto parts and other steel parts. The cryotech process has increased the results of wear resistance without diminishing hardness. In cryotech model fine carbide particle is not added to the microstructure of steel during process and resulting in greater tensile strength.

Deep Cryogenic treatment for racing parts

For the motor sports racers it is the ultimate competitive advantage. Deep cryogenic treatment refines the microstructure of the metal in racing parts and enhances the metal durability.

Cryogenic treatment through dry, inert vapors of LN2 temperature of racing parts below 300° F, helps in reducing the residual stress of the component.

This process of deep cryogenic treatment is applied to brakes, engine parts, transmission and bearings.
