ABSTRACT:
A positioning device for the work-piece backing plate of a table sawing machine includes a machine seat, a work-piece backing plate and a position-limiting device. The work-piece backing plate has its opposite sides respectively fixed with a rack engaged with a gear set installed in the interior of the machine seat. The work-piece backing plate can be controlled by the gear set to move forward and backward on the machine seat. The position-limiting device is assembled in the interior of the machine seat for restricting and fixing the work-piece backing plate in position to prevent the work-piece backing plate from shifting bias in the course of processing, able to elevate processing precision.
