精抛：用以加工轴或孔类零件。。。。。这类零件大部分接纳淬软钢，，，有很高的强度。。。。。大连细密零部件加工大部分高精度机床主轴接纳负压或动压液态转动轴承，，，以确保高稳固性。。。。。切削的極限精度除受车床主轴和床体弯曲刚度的危害外，，，还与沙轮片的挑选和平衡、产品工件焦点孔的加工精度等缘故原由相关。。。。。

碾磨:运用相互配合件互研的基来源理对被加工表层上不规范的突起位置开展挑选加工。。。。。磨砂颗粒直徑、切削速率和钻削热均可精l确使用，，，因而是高细密加工手艺性中获得高精度的加工方法。。。。。

Precision polishing: used for machining shaft or hole parts. Most of these parts are made of quenched and tempered steel, which has high strength. Most high-precision machine tool spindles in Dalian's precision parts processing use negative pressure or dynamic pressure liquid rolling bearings to ensure high stability. The ultimate precision of cutting is not only affected by the bending stiffness of the lathe spindle and bed body, but also by the selection and balance of the sand wheel, the machining accuracy of the core hole of the product workpiece, and other factors.

Grinding: Using the basic principle of mutual cooperation and research, select and process irregular protrusions on the surface to be processed. The diameter of abrasive particles, cutting speed, and drilling heat can all be precisely controlled, making it a high-precision machining method in high-precision machining technology.
