An automatic dual-side saw blade grinding machine includes a common actuator to advance the saw blade to place subsequent teeth in position for grinding and to clamp the saw blade to prevent side-by-side movement during grinding. Thus, no adjustment is required to synchronize the timing between blade rotation and clamping. The actuator is a double-acting two-sided pneumatic piston cylinder which has one end attached directly to the clamping mechanism and the other end attached to the spindle that carries the saw blade through a push-pull cable and a linkage that converts linear motion to rotary motion. The linkage is adjustable to accommodate saw blades having different tooth spacing. The piston cylinder is actuated by an air valve that is cycled by a cam driven by the motor that cycles the blade grinding wheels. Accordingly, machine speed can be changed simply by changing the motor speed. |
