细密大连机械加工的工艺效果是：

①零件的几何形状和相互位置精度抵达微米或角秒级；；；；；

②零件的界线或特征尺寸公差在微米以下;

③零件外貌微观不平度(外貌不平度平均高度差)小于0.1 微米;

④互配件能知足配协力的要求；；；；；

⑤部分零件还能知足准确的力学或其他物理特征要求，，，如浮子陀螺仪扭杆的扭转刚度、挠性元件的刚度系数等。。。

The process effect of precision machining in Dalian is:

① The geometric shape and mutual position accuracy of the parts reach the micrometer or arcsecond level;

② The boundary or characteristic dimension tolerance of the parts is below micrometers;

③ The micro roughness of the part surface (average height difference of surface roughness) is less than 0.1 micrometers;

④ Mutual accessories can meet the requirements of mating force;

⑤ Some parts can also meet precise mechanical or other physical property requirements, such as the torsional stiffness of the float gyroscope torsion bar and the stiffness coefficient of the flexible element.
