Description

Technical Field

[0002] A woodworking band saw is a device used to cut logs into boards. When using existing band saws, the lengths of logs may vary, and the base of the band saw is fixedly installed. When cutting wood with current band saws, the logs usually need to be cut into a relatively fixed length before cutting so that they can fit the fixedly installed support base. When cutting some shorter logs, it is obvious that the fixedly installed support base cannot adapt to logs of different lengths, making it difficult to achieve the support effect of the logs. In addition, the logs are prone to deviation during cutting, resulting in large deviations in cutting. In addition, according to different needs, it is usually necessary to cut logs into boards of different thicknesses. The band saw blades of existing band saws are inconvenient to adjust. In view of the above problems, the inventor proposes a CNC horizontal woodworking band saw to solve the above problems. Utility Model Content
