CNC board saws can complete vertical and horizontal reciprocating cutting, completely replacing electronic cutting saws that can only cut in one direction and costly manual sliding table saws. The efficiency is not only more than 6 times that of a manually pushed table saw, but also can effectively prevent accidents caused by saw blade injuries and improve the personal safety of operators. The system operation is simple and easy to learn, with the advantages of inputting dimensions in a table format, and no need for professional personnel for general operation and processing.
