ABSTRACT:
A sawing machine includes a base body which has a front portion, a rear portion and a worktable with a working surface, and a support body disposed adjacent to the rear portion. The worktable has a sawing slot that opens at the working surface. An upper hollow arm is fixed to the support body and is located above the working surface. A lower hollow arm is fixed to the support body and is located opposite to the upper hollow arm below the working surface. An upper shaft is mounted rotatably in the upper hollow arm, while a lower shaft is mounted rotatably in the lower hollow arm. A driving mechanism is mounted to the support body to drive the shafts to rotate synchronously. Two saw blade mounting members are mounted slidably and respectively to the hollow arms and define cooperatively a straight line passing through the sawing slot. The sawing machine has a converting unit for converting the synchronous rotations of the shafts into synchronous linear movements of the saw-blade mounting members. An elongated saw blade extends along the straight line and has two ends connected to the saw-blade mounting members.
