The role of saw stuck on woodworking band saw machine

There is a device called a saw card on the woodworking band saw. It is an important structure on the band saw. Its main function is to clamp the saw blade so that the cutting part of the saw blade can maintain linear motion when sawing wood. The saw blade is relatively thin, and the rigidity is small. If there is no saw jam, the saw wheel is running at high speed and the saw blade is not controlled, which will cause oscillation and damage the saw blade.
The structure of the saw card:
The saw card generally uses two hard and wear-resistant wooden boards, which are fixed on the machine base or lifting arm with bolts, and can be adjusted appropriately according to the width and thickness of the saw blade, so that the saw blade can smoothly cut the wood without noticeable gap.
The lower saw card is installed on the machine base, which is fixed during sawing; the upper saw card is installed on the lifting arm of the saw card. When sawing wood, the height of the upper saw card can be adjusted at any time according to the height of the wood.
