Woodworking Band Saw MachineSaw wheels are divided into spoke-type saw wheels and spoke-plate saw wheels; for vertical saws, the lower saw wheel is generally the driving wheel, the upper saw wheel is the driven wheel, and the upper saw wheel is the driven wheel. The weight 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 to load, unload and adjust 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 elasticity to the upper saw wheel to ensure the stability of the band saw blade tension during operation; the old type uses a spring or lever weight mechanism, while the new type uses air pressure , hydraulic tensioning device.
The guide device, commonly known as the saw card, is used 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 rail;< ;/p>
The saw card structure has roller type and slider type. The slider type is made of hardwood or wear-resistant plastic.
