Introduction, operating skills and requirements of woodworking band saws

The saw wheel is divided into a web type saw wheel and a web type saw wheel; the vertical saw generally has the lower saw wheel as the driving wheel and the upper saw wheel as the driven wheel. The weight of the upper saw wheel should be 2.5 to 5 times lighter than the lower saw. The cutting speed of the band saw blade is usually 30~60m/s. The upper saw wheel lifting device is used for loading and unloading and adjusting the tension of the band saw blade; the upper saw wheel tilting device is used to prevent the band saw blade from falling off the saw wheel during sawing. The band saw blade tensioning device can give the upper saw wheel elasticity to ensure the stability of the band saw blade tension during operation; the old type uses a spring or a lever hammer mechanism, and the new type uses a pneumatic and hydraulic tensioning device. The guide device is commonly known as the saw card to prevent the band saw blade from twisting or swinging during sawing; the lower saw card is fixed at the lower end of the bed, and the upper saw card can be adjusted up and down along the vertical slide; the saw card structure has a roller type and a slider type , The slider type is made of hardwood or wear-resistant plastic. Band saws are widely used in the wood industry and have a wide range of models. According to the process use, they can be divided into: large band saws, resection band saws and joinery band saws; according to the placement of the saw wheel: vertical and horizontal The vertical and the inclined type are divided into: right type and left type; according to the installation method of the band saw machine: fixed and mobile; according to the number of combination: ordinary band saw and multi-band saw Machine waiting.
