Cold saw blades are circular-type blades widely used in cold saw machines. They keep the blade cold by dissipating the heat generated in the cutting process into the chip that falls off from the cutting area. Cold saw blades can sustain prolonged use due to its ability to stay cold during cutting.
The blades are powered by the cold saw motor, and the operator can vary the speed even during the cut while still maintaining the torque. Providing the blade at a steady feed rate will ensure there is virtually no dust, and because there is no heat, the chances of discoloration are practically none.
A properly maintained cold saw blade should last a long time, even with extensive use. Typically, cold saw blades can endure up to 1,000 cuts before it needs to sharpen. Also, a high-quality cold saw blade can be re-sharpened 40 times during its lifespan. Here are a few tips get the most out of your cold saw blade:
Choose The Correct Blade
Using the wrong blade for a particular material will dull the blade faster and will need to be sharpened quicker. Frequent re-sharpening will shorten the lifespan of the cold saw blade.
Use a fine-toothed blade for thinner material and a coarser tooth blade for solid or thick-walled material
Properly Install The Cold Saw Blade
Proper installation of the blade is an easy process but requires great attention to detail. Make sure that the clamps and screws and tighten. Also, remove any debris from the saw machine and the spindle to eliminate the possibility of backlash.
Let The Blade Do The Work
Applying pressure on the material during the cut will not only yield an uneven cut but will also damage the blade and shorten its lifespan. It is important to learn and understand your machine’s speed variations, feed rates, and chip load to get extract the maximum out of your cold saw blades.
Use Appropriate Lubricants
Even though a cold saw blade can perform without lubricants, but it is highly recommended to lubricate the blade and the cutting material during the cutting process. Using coolants will keep the blade and cutting material cold by removing frictional heat.
Coolants also wash away any residual chips which help in preventing the blade bonding to the metal surface.
