Blade is an indispensable part of wood planer, which is used to plane wood. So, what should be paid attention to when using the blade of a woodworking planer?
In the normal cutting state, because of the high speed of the cutter shaft, the centrifugal force on the blade is far greater than the cutting force. If the radial extension of the blade is too large, the cutting force will be increased, and the degree of injury caused by accidental contact of the hand will also be large; if the extension of the blade is inconsistent or the tooth chipping is damaged, the cutter shaft will be affected by the rotating unbalanced force and the cutting force will be uneven, and the workpiece will fall sideways due to the unbalanced cutting force, or bounce due to the periodic impact; if the blade is too narrow or the fastening is not firm, it will be in the strong centrifugal force Under the action of, the blade will produce asymmetric sliding in the radial direction, and even cause the blade flying out to hurt people.
1. The planer must be equipped with safety protection device, otherwise it is forbidden to use.
2. The planer shall be stable and operated by both hands. When planing large surface, the hand shall be pressed on the material; when planing small material, the finger shall not be less than half of the material height, not less than 5cm. It is forbidden to push after materials by hand. Do not wear gloves.
3. The planing amount shall not exceed 1.5mm each time. The feeding speed shall be kept even, and the force shall be light when passing through the planer. It is forbidden to return the material above the planer.
4. Planing wood with a thickness of 3cm and a length of less than 40cm must use a pressing plate or a push stick, and it is forbidden to push it by hand. Wood with a thickness of 1.5cm and a length of less than 25cm shall not be processed on a planer.
5. In case of knots, it is necessary to slow down the speed of pushing materials. It is forbidden to push materials on knots by hand. Old plates must be cleaned of nails, mud and sand. If the planed timber has cracks and other defects, it must be treated before planing.
6. The blade must be switched off and locked. It is forbidden to extend your hand into the inner side of the safety guard board to move the guard board or remove the safety guard board for planing.
7. The blade weight of the same planer must be the same, and the clamping plate of the tool holder must be consistent. The blade weld beyond the blade and the tool with cracks shall not be used. The screw for fastening the blade shall be embedded in the groove and not less than 10 mm away from the blade arm.
8.Operate the machine according to the number of people, cut off the power supply and lock the door.
