    • A precision saw is the subject of the present invention. A framework mounts a planar member and presents a work surface having an opening for receiving a saw blade. A C-member is coupled with the framework and has upper and lower arms extending parallel to and above and below the work surface. The planar member is mounted for pivotal movement by a pivot rod positioned at a point in a horizontal plane located substantially at the center of the bight of the member. A saw blade extends between the upper and lower arms for cutting a work piece and a drive system is provided for moving the C-member in a generally vertical plane about the single pivot point.
    • 精密锯是本发明的主题。 框架安装平面构件并呈现具有用于接收锯片的开口的工作表面。 C构件与框架联接,并且具有平行于工作表面上方和下方延伸的上臂和下臂。 平面构件被安装成通过位于基本上位于构件的弯部的中心的水平面中的点处的枢轴杆枢转运动。 锯片在上臂和下臂之间延伸以切割工件,并且提供驱动系统以用于在围绕单个枢转点的大致垂直的平面中移动C形构件。
