Good method for grinding saw blade of sports car band saw machine

After the band saw blade of the woodworking band saw becomes blunt, the sawing of wood will not be smooth and the sawing surface will be very rough, so it is necessary to replace the woodworking band saw machine with a new saw blade or grind the band saw blade. The following sports car band saw machine mainly talks about the method of grinding the band saw blade by hand. A file or an angle grinder can be used for grinding the band saw blade, but the efficiency of using the file to file the saw teeth is very low, and the angle of the saw teeth and the curve integrity of the root of the saw teeth cannot be guaranteed, so that the saw blade is easy to be damaged due to stress concentration when sawing wood.

Grinding sawteeth with an angle grinder is very fast, but the angle grinder is difficult to control and easy to grind the sawteeth. While grinding with a small grinder is simpler than the above two, it is also easy to grind the sawteeth outside the target sawteeth due to mistakes. Having said so much, does it feel very difficult to grind the band saw blade? Let's look at how to grind the saw blade easily. According to the type of saw blade saw teeth, measure the size of saw tooth shape curve and buy a cylindrical or brush head shaped corundum small grinding head with appropriate size. Place the grinding head on the saw tooth of the band saw blade, and check whether the diameter conforms to the curve of the saw tooth and whether it is suitable to grind the front angle of the saw tooth. Clamp the saw blade with a clamp to hold the saw teeth upward, install a small grinding head on an adjustable hand electric drill, adjust the rotation speed of the electric drill to a high level, place the grinding head on the curve of the saw teeth, lean against the front corner of the saw teeth, and gently move the grinding head back and forth several times to sharpen the saw teeth. Note: During grinding, care should be taken not to use too much force to prevent the serrations from being worn out due to excessive grinding. According to the saw path of the saw blade, the tooth shifting direction of each serration, the axis of the grinding head should have a certain deflection angle with the general direction of the saw blade, so that the side edge can be sharpened, the cutting edge of each serration of the band saw blade in both directions can be sharpened, and the cutting surface will be flat when sawing wood.
