各种加工方法的加工精度 |
|
newmaker |
|
加工精度是加工后零件表面的实际尺寸、形状、位置三种几何参数与图纸要求的理想几何参数的符合程度。理想的几何参数,对尺寸而言,就是平均尺寸;对表面几何形状而言,就是绝对的圆、圆柱、平面、锥面和直线等;对表面之间的相互位置而言,就是绝对的平行、垂直、同轴、对称等。零件实际几何参数与理想几何参数的偏离数值称为加工误差。加工方法 | IT等级 | 01 | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 研磨 | | | | | | | | | | | | | 珩 | | | | | | | | | | | | | | | | 圆磨 | | | | | | | | | | | | | | | | 平磨 | | | | | | | | | | | | | | | | 金钢石磨 | | | | | | | | | | | | | | | | | 金刚石镗 | | | | | | | | | | | | | | | | | 拉削 | | | | | | | | | | | | | | | | | 铰孔 | | | | | | | | | | | | | | | 车 | | | | | | | | | | | | | | | 镗 | | | | | | | | | | | | | | | 铣 | | | | | | | | | | | | | | | | 刨插 | | | | | | | | | | | | | | | | | | 钻孔 | | | | | | | | | | | | | | |
