Band saw plays a very important role in woodworking, so how can we give full play to the advantages of band saw? Let's talk about it from writer.
1. The bearing working site and machine tool used on the large-scale woodworking band saw shall be cleaned frequently and kept clean, especially the resin sawdust on the saw blade and saw wheel. Regularly add lubricating oil to the bearing, gear screw, slide and other friction parts of the machine tool. During operation, pay attention to whether the rolling bearings of the upper and lower saw wheels are abnormal, and the temperature shall not exceed 60 ℃.
2. Check and calibrate all parts frequently. Check whether the upper and lower saw wheels are in a vertical plane by means of hanging wire. If there is any distortion, it is appropriate to adjust the upper wheel. If the gap is too large, the lower wheel can also be adjusted. After the upper and lower wheels work for a period of time, there will always be some wear. If you often check whether the lifting system of the upper wheel is flexible and reliable; whether the lifting device of the saw card slides up and down freely; whether the automatic tensioning device is flexible for pipe use. Whether the parts are damaged; whether the connecting parts are loose, etc. If abnormal phenomenon is found, it shall be solved in time. Or scrub oil or repair correction, or even replacement, to ensure the safe and normal operation of the machine tool.
3. The band saw machine uses the saw blade as the cutting tool, through the reciprocating motion of the band saw or the band saw, or the rotating motion of the circular saw to cut and divide the wood. The common band saw is circular saw. Sawing injury accidents mainly include sawing injury, saw blade fracture ejection, wood strike injury, etc. Sawing injuries are prevented by using safety guards and proper operation.
4. The thickness of saw blade shall be suitable for the matched band saw wheel. Avoid using large thickness saw blade for small wheel to cause fracture and personal injury. The saw teeth shall be sharp and the depth of the teeth shall not exceed 1/4 of the width of the saw blade. The welding of band saw blade shall be firm and flat, the number of joint wood shall be more than 3, the length between two joints shall be more than 1 / 5 of the total length, and the thickness of joint shall be basically the same as that of saw blade. Strictly control the transverse crack of the band saw blade. If the crack is too long, cut it and weld again. The track of the large band saw shall be straight, with travel switches at both ends, and warning bars shall be set on both sides of the car.
In this way, the band saw can play a role in the working process.
