How to install this saw blade for sawing wood?

The saw blade rotates counterclockwise, so the tooth edge of the sawtooth should be installed in the direction of the sawed object.

Saw blade is a general name for thin circular tools used to cut solid materials. Saw blades can be divided into: diamond saw blades for stone cutting; High-speed steel saw blade for cutting metal materials; Carbide saw blade is used for cutting solid wood, furniture, man-made board, aluminum alloy, aluminum profile, radiator, plastic, plastic steel and so on.

Selection of saw blade: according to the type and thickness of sawing material, sawing speed, sawing direction, feeding speed and sawing width, select the saw blade correctly.

Choice of sawtooth angle: the angle of sawtooth is the position of sawtooth when cutting.

① The rake angle mainly affects the force consumed by sawdust. The larger the rake angle, the better the sharpness of sawtooth cutting, the lighter it is to saw and the more labor-saving it is to push. Generally, when the processed material is soft, choose a larger rake angle, otherwise choose a smaller rake angle.

② The back angle is the included angle between the sawtooth and the machined surface, and its function is to prevent the sawtooth from rubbing against the machined surface. The greater the back angle, the smaller the friction and the smoother the processed products. The back angle of general cemented carbide saw blade is 65438 05℃.

③ The wedge angle is derived from the front angle and the back angle. However, the wedge angle should not be too small, which has a certain effect on maintaining the strength, heat dissipation and durability of the teeth. The sum of rake angle γ, rake angle α and wedge angle β is equal to 90℃.

Requirements for using saw blades:

(1) When working, the workpiece should be fixed and the profile should be positioned in the same direction as the cutting direction to avoid abnormal cutting. Don't apply lateral pressure or curve cutting, and the feed should be stable, so as to avoid the impact contact between the saw blade and the workpiece, which will cause the saw blade to be damaged or the workpiece to fly out and cause an accident.

(2) When abnormal sound and vibration, rough cutting surface or peculiar smell are found during work, the operation must be stopped immediately, checked in time, and troubleshooting should be carried out to avoid accidents.

(3) When starting cutting and stopping cutting, the feed speed should not be too fast to avoid broken teeth.

(4) Ensure the smoothness of the equipment chip removal groove and slag suction device, and prevent slag from piling up into blocks, which will affect production and safety.

⑤ During dry cutting, do not cut continuously for a long time, so as not to affect the service life and cutting effect of the saw blade; When cutting wet film, water should be added for cutting to avoid leakage.
