我厂自制的φ160mm落地镗床,是一台大型工作母机。主要用于本厂自制非标机床的床身和箱体的加工。镗头主轴箱垂直行程为1.5米,主轴立柱横向行程为3.2米.主辅纵横位移量原只能靠指示器和刻线尺指示,误差一般在0.5mm,加工精度无法保证,经常出现孔距超差的床身和箱体,迫使下道工序配作,造成工时和材料的浪费。为此, I plant self-made φ160mm floor boring machine, is a large-scale work machine. Mainly used for factory-made non-standard machine bed bed and box processing. Boring headstock vertical stroke of 1.5 meters, spindle column horizontal travel of 3.2 meters. The main vertical and horizontal displacement of the original can only rely on the indicator and the ruler, error is generally 0.5mm, processing accuracy can not be guaranteed, often appear pitch Ultra-poor bed and box, forcing the next procedure assigned, resulting in a waste of working hours and materials. to this end,
