Single line crystalline silicon cutting machine

The invention discloses a single line crystalline silicon cutting machine. The single line crystalline silicon cutting machine comprises a machine body base (1), a feed mechanism arranged on the machine body base (1) and a cutting mechanism arranged on one side of the machine body base (1) for cutting workpieces. A positioning mechanism for positioning the workpieces and a work table (6) are arranged on the feed mechanism. A clamping mechanism for fixing and rotating the workpieces is further arranged on the work table (6). A feed lead screw (2) for controlling the feed mechanism to move is arranged on the lower surface between the feed mechanism and the machine body base (1). A drive mechanism connected with the feed lead screw (2) is installed on the upper part of the machine body base (1). The single line crystalline silicon cutting machine provided by the invention is simple in structure, easy to realize, precise and convenient to position, improves the precision and cutting efficiency of crystalline sili
