Safety Regulations For The Use Of Band Saws

A sawing machine uses a saw as a cutting tool to cut and carve wood through the reciprocating motion of a bar saw or band saw, or the rotating motion of a circular saw. Common sawing machines include band saws and circular saws. The main types of sawing injury accidents include sawing injuries, saw blade breakage and ejection, and wood impact injuries. Sawing injuries are prevented through the use of safety protection devices and proper operation.
① The thickness of the band saw blade should be compatible with the matching band saw wheel. Avoid using thick saw blades for small wheels, which may cause breakage and injury.
② The serrations should be sharp, and the tooth depth should not exceed 1/4 of the saw blade width.
③ The welding of the saw blade should be firm and flat, with no more than 3 joints. The length between the two joints should be more than 1/5 of the total length, and the thickness of the joint should be basically the same as that of the saw blade.
④ Strictly control the transverse cracks of the saw blade, and if the cracks are too long, they should be cut off and re welded (see Table 1).
⑤ The track of the large band saw machine should be straight, with travel switches at both ends, and warning signs should be set up on both sides of the car.
