轴类零件是常见的大连数控加工零件之一。按轴类零件结构大局分歧，通常可分为光轴、阶梯轴和异形轴三类；或分为实心轴、空心轴等。它们在机械中用来支承齿轮、带轮等传动零件，以传递转矩或活动。台阶轴的加工工艺较为典型，反映了轴类零件加工的大部门内容与根基法规。

Axis parts are one of the common CNC machining parts in Dalian. According to the different structural forms of shaft components, they can generally be divided into three categories: optical axis, stepped axis, and irregular axis; Or divided into solid shafts, hollow shafts, etc. They are used in machines to support transmission parts such as gears and pulleys to transmit torque or motion. The machining process of step shafts is relatively typical, reflecting most of the content and basic rules of shaft parts machining.
