METHOD FOR CUTTING WORKPIECE BY BAND SAWING MACHINE, AND BAND SAWING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a method for cutting a workpiece while suppressing noise due to chattering vibration of a band saw blade, and a band sawing machine.;SOLUTION: When the workpiece W is cut by the endless band saw blade 13 wound between a driving wheel 29 and a driven wheel 31, forced vibration for exhibiting a phase where vibration in the rotating direction of the driving wheel 29 is approximately inverse to that of the driven wheel 31 is applied to the wheel 29 for cutting the workpiece W. In order to vibrate the driving wheel 29 in the rotating direction, pulses with a frequency of 116-135 Hz, desirably of 127 Hz are applied to a driving motor 37 for rotating the wheel 29.;COPYRIGHT: (C)2007,JPO&INPIT
