The choice of abrasive wheels designed for sharpening band saws depends on the material from which the saws are made.
The choice of abrasive wheels designed for sharpening band saws depends on the material from which the saws are made.
The material for the band saw is selected depending on its function: In the production process of a saw for wood, tool steel (alloy) is in great demand.
Saws that process carbon steels and non-ferrous metals (minimum thickness) are equipped with tool steel.
The teeth of these saws are necessarily tempered with high frequency currents.
Bimetallic saws are used for cutting metal products made of high-strength metals, such as titanium.
The density of such saws is made of springy steel, and the strip with teeth is made of high-speed steel (the teeth contain cobalt and tungsten).
The strongest and most resistant to wear are the teeth deposited with stellite, a very strong alloy with a cobalt (chromium) base and an admixture of molybdenum (tungsten).
These saws perfectly cut bricks, tires, heat-resistant alloys, as well as fiberglass.
Grinding wheels: types, shapes, grit of abrasive Grinding wheels are selected based on the materials from which the saws are made: corundum circles are suitable for teeth made of tool steel; Diamond or borazone circles are needed for biometric saws.
It is extremely important to correctly choose the optimal circle shape for sharpening band saws, which depends on the characteristics of a particular saw (tooth profile, facets) and sharpening methods.
There are circles for sharpening: disc-shaped; cup-shaped; profiled (copy the tooth parameter); flat.
Another important criterion is the grain size of the abrasive.
It should fit the sharpening levels.
To determine the grain size of the abrasive, you need to view a special table.
