精抛：用以加工轴或孔类零件。这类零件大部门选取淬软钢，有很高的强度。大连精密零部件加工大部门高精度机床主轴选取负压或动压液态滚动轴承，以确保高不变性。切削的極限精度除受车床主轴和床体弯曲刚度的风险表，还与沙略飕的遴选和平衡、产品工件主题孔的加工精度等原因有关。

碾磨:使用相互共同件互研的根基道理对被加工表层上不规范的突起地位发展遴选加工。磨砂颗粒直徑、切削快率和钻削热均可精l确把持，因而是高精密加工技术性中得到高精度的加工方式。

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.
