在机械加工中,常遇到箱体件同轴孔加工的同轴度误差问题。当同轴孔距离不大,可以一次加工完成时,同轴度误差只与设备本身精度有关;当同轴孔距离较大而需调头加工时,其同轴度误差将受多项因素影响,主要由工作台定位误差.找正误差和仪表灵敏度等组成。考虑到找正误差和仪表灵敏度等因素可人为控制在较低范围内,因此只要控制t_定<0.6t(t_定—一因工作台定位误差而产生的同轴度误差,t——同
In machining, often encountered coaxial coaxial hole processing box member error problem. When the coaxial hole distance is small, you can once the processing is completed, the coaxial error is only related to the accuracy of the device itself; when the coaxial hole is large and need to turn the first processing, the coaxial error will be affected by a number of factors, Mainly by the workbench positioning error. To find the error and instrument sensitivity and other components. Taking into account factors such as find errors and instrument sensitivity can be artificially controlled in the lower range, so long as the control t_set <0.6t (t_set - a positioning error due to table coaxial error, t-- with
