1. The narrower the jig saw blade, the smaller the radius of the saw curve. According to experience: a 12 mm wide saw blade can cut a curve with a radius of curvature of about 70 mm; a 25 mm wide saw blade can cut a curve with a radius of curvature of about 250 mm; a 35 mm wide saw blade can cut the radius of curvature A curve of approximately 450 mm; a 50 mm wide saw blade that can cut a curve with a radius of curvature of approximately 800 mm. When sawing a curve with a small radius of curvature with a wide saw blade, you can first saw several radial kerfs and then cut them by curve.
2. When straight angle sawing is used to cut a right-angled corner, you can drill a round hole at the corner and then saw it in the direction of the arrow. When the corner is turned to a large area, it can be sawed directly.
3. Bending sawing method is generally carried out by sawing and cutting. It can also be cut by the curve die, that is, the curve template is applied to the saw ratio, and the processed piece is sent to the curve template to be sawed, and the corresponding curve can be sawed. The curvature of the material should match the width and width of the saw blade.
4. When the bevel saw cuts the bevel, the machine table can be tilted to the desired angle. It is also possible not to adjust the table top of the machine tool, and to make a wedge-shaped wood board with a corresponding inclination fixed to the table surface, and when the workpiece is sent along the wedge-shaped wood board, the required slope surface is sawed.
5. When a tapered saw saws a large, small workpiece, the template is often used to cut a piece of wood that is slightly longer than the workpiece to the desired slope and plan as a template. The template should not be too thick, the small head should be kept at about 10 mm, and then the tack of the template will be used as a head. When sawing, the workpiece will be placed against the template, and the surface template will be close to the saw ratio. The template should be made in two pieces, which can be used before and after to improve work efficiency.
