ABSTRACT:
A circular saw arrangement has a table arrangement which provides a support area for the workpiece to be cut. For cutting the workpiece, a saw unit is provided for chop-saw and rip-saw cutting. The saw unit contains a power saw blade which is pivotally lowered from a raised position in the direction of the support area for chop-saw cutting. The axis of the saw blade is spaced from and parallel to the axis of the armature of the motor, and the pivotable movement of the saw blade is centered about the armature axis of the motor so that the motor remains stationary during the chop-saw movement. Elongate guide rods are supported in a cantilevered manner by a vertical support member connected to the table arrangement wherein the distance between the guide rods and the table arrangement remains constant in all positions of the saw blade, and the saw unit is slidably carried on the elongate guide rods for rip-saw cutting. Further, the vertical support is pivotally supported by the table arrangement to provide for mitre cutting.
