机床的加工精度-----电磁阀生产

发布者:admin发布时间:2018-09-08 10:45:19点击量:294

机床的加工精度是保证加工工件的尺寸和形状精度的性能。它决定于机床的几何精度,传动精度,静态刚度和动态刚度等。 ? ? 机床的几何精度指的是机床主要零部件几何形状的准确性和各部件间相互位置的准确也它是机床加工精度的保证条件。传动精度是招机床上完成工作指令而产生相对运动的部件问,其相对运动的准确性。它取决于传动系统的设计、传动件的制造和笼配调焚等情况。机床的静态刚度指的是机床在受到切朗力和工件重量作用时抵抗变形的能力。这种能力越强,则在同样作用力T,产生的变形越小使机床得到较好的加上按度;扔床的动态刚度是指机床在周期性变化的力的作用下抵抗变形的能力,也就是抗震性。如果机床在周期性变化的力的作用下产生震办不但不能保证加工工件的精度和租糙波还会损坏刀具和机床。 ? 机床加工工件表面组糙度岗低是机床主要性朗招标之一,对于招加工机床尤为重要。影响加工工件表面粗糙度的因素很多,除刀具的几润角氏加工土件材料性质等工艺因素蜘还有机床的进给量,运动的平稳性等。有关加工精度和表面粗植皮的内容详见有关手册 专业高端电磁阀、电动阀、气动阀---重庆盾铭为您提供服务!
