Wood working equipment

Wood working is dramatically changing the profitability of the wood and paper industry. It is a proven process that provides longer running, sharper tools for carbide or high speed steel tools. The increased life expectancy is dependant on several underlying factors.

First and foremost is the heat treatment process. Many tools are manufactured with less than the best heat treatment. Often because of the nature of the product and / or economics, some treatments have to be performed in less than great methods in order to heat treat their product.

Look at just one example. A bandsaw blade must have a sharp, hardened tooth, but a soft back in order to flex and not break. The blade is often induction or flame hardened on the tooth by very localized heating. This is followed by a waterfall of oil to quench the tooth. Then heat is applied again to temper the steel. All this is done on a band of material traveling at several feet per minute. The grain structure near the bottom of the tooth is in various phases of transformation and the temper was accomplished at such a fast speed there still exists unstable Martensite and great amounts of non-productive Austenite. Cryogenic Processing solves many of these problems.

Carbide tipped saw blades also gain dramatic wear increases from the improved binder material used to hold the carbide grains on the cutting edge. Cryogenic Processing does two tings. First, it removes the stresses that were created during manufacturing. Then it strengthens the gripping power of the binder to hold the carbide in place and so it will cut longer.
