IPC: B23D55/10
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To beautifully finish the cutting face and improve the life of a saw edge by increasing and decreasing the tensile force applied to the saw edge according to the increase/decrease in the cutting resistance in cutting a work by the saw edge. SOLUTION: An endless belt saw edge B is wound around a drive wheel 21 and a driven wheel 23.

The driven wheel 23 is provided with a saw speed detector 43 on a shaft 27 and has the tip of a piston rod 47 of a tension cylinder 45 attached thereto. The power detected by the power detector 41 and the saw speed detected by the saw speed detector 43 are put in an arithmetic processing unit 77 so as to find the tensile force of the belt saw blade B proportional to the cutting resistance. The tensile force of the belt saw edge B is controlled by moving the piston rod 47 of the tension cylinder 45.  This constitution can beautifully finish the cutting face by suppressing the bending of the belt saw edge B, even if the cutting resistance is increased, and the decrease in the cutting resistance supplies no excessive tensile force so as to elongate the life of the belt saw edge.
