軸類零件是常見的大連數控加工零件之一。按軸類零件結構形式不同，一般可分為光軸、階梯軸和異形軸三類；或分為實心軸、空心軸等。它們在機器中用來支承齒輪、帶輪等傳動零件，以傳遞轉矩或運動。臺階軸的加工工藝較為典型，反映了軸類零件加工的大部分內容與基本規律。

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.
