Amana Tool Saw Blades


Since 1972, Amana Tool has been serving the woodworking industry with high-quality, industrial-grade carbide-tipped saw blades. In order to provide users with the highest quality, longest lasting industrial saw blades, we use only the finest raw materials and the most innovative technology available in the market while keeping informed of the latest materials and market demands. Below are steps that we use in the production of our industrial saw blades.




Body Production
The Amana Tool process begins with saw bodies made from special alloy steel that enables strength and elasticity within the saw body. Produced in Europe, the steel contains high concentrations of carbon, which is hardened to 44 RC in order to maintain the high demands of the circular saw’s operation.


Important steps in Amana Tool’s saw body production

A.
In order to produce high quality saw blades, the blades are straightened three seperate times during production.
1) before the bodies are cut by laser, 2) after the carbide brazing process, and 3) at the end of the grinding process.


B.
Heat treating (annealing) is performed after the saw bodies are laser cut.  This avoids hardening of the area around the laser cut. If this step is omitted, the body of the saw blade could crack during operation.


C.
The tip seat is sandblasted in order to clean the seat and prepare it for the brazing process.


D.
Tension rings are pressed into the saw bodies in order to improve the resistance of the body to side forces. Different tensions are created for different types of saw blades, as well as various applications.


E.
Expansion slots are laser cut into the saw bodies, and copper plugs are added to the ends of the slots. These features virtually eliminate vibration while reducing noise and increasing the life of the cutting edge.


Brazing
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.



Grinding process
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.



Straightening process
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.

Balancing 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).

Laser etching
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.


       
carbide tipped saw blade teeth
Carbide Tips
Extra-large European carbide tips allow many saw
blade re sharpenings, giving the saw blade longer life. 400 grit diamond wheels are used for grinding face,
side and top. Brazed by the latest computerized
technology that ensures consistency.
