本机在组合锯基础上，通过优化改良采用四立柱液压精密导向，改变了传统的立滑板导向，导向精度高、震动小，由于钢性好、配合间隙小、润滑好等优点使所生产的板材厚薄误差小，表面平整度高。同样提高了刀头锯片的使用寿命和降低了电费节省了人工。四立柱单臂液压组合锯是一款板材加工的理想设备。 The machine in the combination saw based on, by optimizing the modified by four column hydraulic precision orientation, has changed the traditional vertical slide guide, high guiding precision, small vibration, due to the rigid, with small clearance and lubrication advantages make the production of sheet thickness error is small, smooth surface of high. Similarly, the service life of the cutter head saw blade is improved, and the labor saving is reduced. Four column hydraulic combination saw is an ideal device for a sheet processing.
