Hollow lead screw shaft machining method

A hollow lead screw shaft machining method comprises the following steps that firstly, materials are selected; (2) rolling the lead screw; (3) cutting off the lead screw; (4) turning an end face step and roughly machining an inner hole; (5) turning the other end and finishing an inner hole; and (6) cleaning and rust prevention. Batch production can be achieved, the machining cost is reduced, and the product quality is guaranteed; unification of a measuring reference and a machining positioning reference is realized in the whole machining process, so that the quality is stable and reliable. 一种中空丝杠轴加工方法，包括以下步骤：步骤(1)选材；步骤(2)滚压丝杠；步骤(3)丝杠切断；步骤(4)车削端面台阶和粗加工内孔；步骤(5)车削另一端和精加工内孔；步骤(6)清洗防锈。本发明可批量生产，降低加工成本，保证产品质量；整个加工过程实现了测量基准与加工定位基准的统一，使质量稳定可靠。
