Stainless steel honing tube honing method

① During honing, the workpiece is installed on the honing machine table or in the fixture, and the honing head with a number of whetstone bars is inserted into the machined hole, which is driven by the machine tool spindle to rotate and reciprocate axially. When the whetstone bar contacts the hole wall with a certain pressure, a very thin layer of metal can be cut off. The honing head and the main shaft generally form a floating connection. ② There are several types of honing heads: mechanical pressure type, pneumatic or hydraulic automatic pressure regulation type. The honing head shown in the figure is a mechanical pressure type, and a hydraulic pressure regulating type is often used in actual production. ①Honing is a high-efficiency machining method that makes the machined surface of the workpiece achieve high precision, high surface quality and long life. It can effectively improve dimensional accuracy, shape accuracy and reduce the Ra value, but it cannot improve the quality of holes and other surfaces. position accuracy. ② It can process cast iron parts, hardened and unhardened steel parts and bronze parts, etc., but it is not suitable to process non-ferrous metal parts with high toughness. ③ Honing is mainly used for hole machining. In hole honing, it is guided by the center of the original machined hole. The machining aperture range is φ5～φ500, and the aspect ratio can reach 10. ④ Honing is widely used to process cylinder holes, cylinder barrels, valve holes and various gun barrels in mass production. It can also be used in single piece and small batch production. ⑤ The coaxiality cannot be determined during honing. ⑥ Compared with grinding, honing has the characteristics of reducing manual labor, high productivity, and easy automation.
