Abstract

Disclosed is a high-speed cut-off saw of numerical control, comprising a circular sawing machine (3) and a circular sawing blade (12) thereof. Two sides of the circular sawing machine (3) are respectively provided with a material loading workbench (2) and a material discharging workbench (4), wherein an automatic material pushing machine (5) is provided on the material discharging workbench (4). Two sides of the circular sawing blade (12) are both installed with a material-conveying pressing roller (13) and a material-conveying supporting roller (22), wherein the material-conveying pressing roller (13) and the material-conveying supporting roller (22) are provided in pairs. The material-conveying pressing roller (13) is slidably supported on a lifting beam (18) via a pressing-roller cylinder (19), the lifting beam (18) is slidably supported on a machine frame (10) of the circular sawing machine (3), and a beam lifting mechanism (15) is further installed between the machine frame (10) and the lifting beam (18). The material-conveying supporting rollers (22) at the two sides of the circular sawing blade (12) are in mutual transmission connection. The high-speed cut-off saw of numerical control has high cut-off efficiency, the quality of cutting off is stable and the recovery ratio is high, thereby efficiently reducing the non-productive time during a saw cutting process, and reducing the wastage of wood resources.
