Abstract

PURPOSE:To perform cutting always with a constant amount of cut, by lowering a saw frame only for a prescribed time at both left and right turning points of rocking motion and controlling to perform cutting work through the rocking motion for the rest of time. CONSTITUTION:A saw frame 9 is operated rocking movement by applying laterally shuttling motion integrally to left and right cam plates 32, 33 and telescopically moving left and right servo cylinders 17, 18 reversely to each other. This rocking motion reaching left and right turning points is detected by a microprocessor 41, and this detection alternately generates a cam plate rightward instruction and leftward instruction, then solenoids E, F of a direction selector valve 43 in a cam plate shuttle device are alternately excited to cause a rod 31 of an oil hydraulic cylinder to shuttle, move the left and right cam plates 32, 33 and rock the saw frame to the opposite direction. Further only for a fixed time from the detection, a lowering instruction signal is output to always perform cutting with a constant amount of cutting.
