The brake is a braking device on the woodworking band saw machine, because the inertia of the lower saw wheel is relatively large when the band saw is running. If the saw is stopped without braking, the rotational inertia of the lower wheel will last a long time to stop. Using a brake to brake the saw wheel can shorten the idle time when the saw is stopped. This is the main function of the band saw brake.
There is a brake hand wheel on the sawing machine, and a wooden board for braking is installed on the eccentric shaft. By turning the hand wheel, the wooden board on the eccentric shaft can be pressed against the surface of the lower saw wheel, and the lower saw wheel is braked by friction on the lower wheel.
The wooden boards used in the brakes are hard-wearing hardwoods. Because they are wooden, they need to be checked and replaced frequently to ensure the sensitivity of the brakes. Some brake hubs are cast on the lower saw wheel, and the lower saw wheel can be braked by pressing on the hub.
