How to Sharpen a Woodworking Saw Blade Correctly?
1. The grinding is mainly done on the back and front of the teeth. If there are no special requirements, the tooth surface will not be sharpened.
2. After grinding, the conditions for the front and rear angles to remain unchanged are: the angle between the grinding wheel working surface and the front and rear tooth surfaces to be sharpened is equal to the grinding angle, and the grinding wheel distance movement amount is equal to the grinding amount. Make the working surface of the grinding wheel parallel to the tooth surface to be ground, then touch it lightly, then make the working surface of the grinding wheel leave the tooth surface, and then adjust the angle of the grinding wheel working surface according to the grinding conditions. The grinding angle is adjusted so that the working surface of the grinding wheel is in contact with the tooth surface.
3. The grinding depth during rough grinding is 0.01-0.05 mm; the recommended feed speed is 1-2 m/min.
4. Manually finely grind the saw teeth. After the tooth blade has a small amount of wear and chipping, use a silicon chloride grinding wheel to grind the saw teeth. If it still needs to be ground, you can use a hand grinder to finely grind the saw teeth to make the tooth blade sharper. When fine grinding, the force should be uniform, and when the grinding tool moves back and forth, the working surface of the grinding tool should move in parallel. Grind the same amount to ensure all tooth tips are on the same plane.
