轴类零件是常见的大连细密零部件加工之一。。。按轴类零件结构形式差别，，，一样平常可分为光轴、蹊径轴和异形轴三类；；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，，，以转达转矩或运动。。。台阶轴的加工工艺较为典范，，，反应了轴类零件加工的大部分内容与基本纪律。。。

Shaft components are one of the common precision parts machined 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.
