In this process, extra large carbide tips are attached to the saw blade. Amana Tool uses five different grades of carbide in the production of our saw blades. Each carbide grade has unique characteristics, including varying “Wolfram” grain sizes, the amount of cobalt binder used and other additional materials. Different carbide grades are required for each cutting application to meet special demands, such as resistance to impact force when cutting steel or maintaining a long-lasting cutting edge in abrasive material such as MDF, chipboard, etc.
Brazing is performed by automatic induction brazing machines, which ensure a stable, controlled process. A triple layer brazing silver is used to get the maximum brazing force with minimum internal heat expansion force. After brazing, the saw blade is cleaned by sand blasting.
The saw blades are ground by fully automated CNC controlled machines. Amana Tool uses very fine grinding diamond wheels to create a superior cutting edge for each saw blade. The angles and geometry of the saw blade teeth are then adjusted for the specific saw blade application.
A saw blade’s cutting quality is directly related to the straightness of the blade itself. The straightening process is therefore one of the most important aspects in the production of a superior quality industrial saw blade.
All Amana Tool saw blades are straightened using a unique automated machine developed in-house by our engineers. This machine is completely automated and requires no human interference, unlike the standard “hammering” method of straightening blades, which is a completely manual process.
In order to minimize vibrations, reduce noise level and maintain the safety and accuracy of the saw blade, Amana Tool adds a very unique step to the manufacturing process. Most of our saw blades are “balanced” according to ISO standard 1940 for a level balance of G6.3. Look for our unique “balance” countersinks on the perimeter(s).
All critical saw blade specifications and safety information is laser etched directly on the saw blade body. This way, all critical information is available for the entire life of the saw blade for the benefit of the user’s safety.
The straightness of the saw blade, the grinding quality, tension rings and carbide grade all play major roles in affecting the quality of any saw blade. Unfortunately, the normal human eye can barely detect the difference between a high-quality saw blade and one of lesser quality. It is our obligation to ensure that all Amana Tool saw blades have the finest straightness, grinding quality and tension properties, which equates to performance levels of the highest standards.
