We apply the new technology--honing process to the cylinder manufacture industry, it is effective for improving precision surface of cylinder, further, to improve the quality of hydraulic riveting machine, increase trouble-free period and decrease the risk of oil leakage.

Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but may also improve the surface texture. Typical applications are the finishing of cylinders for internal combustion engines, air bearing spindles and gears.

There are many types of hones but all consist of one or more abrasive stones that are held under pressure against the surface they are working on. In terms of sharpening knives, a honing steel does not actually hone knives, but simply realigns the metal along the edge. Other similar processes are lapping and superfinishing.

A honing machine, ironically, is relatively inaccurate and compliant. Instead of relying on the accuracy of the machine tool, it relies on the averaging effect between the stone and the workpiece. In fact, compliance is a requirement of a honing machine that is necessary for the averaging effect to occur. This leads to an obvious difference between the two machines: in a grinder the stone is rigidly attached to a slide, while in honing the stone is actuated with pneumatic or hydraulic pressure. High-precision workpieces are usually ground and then honed. Grinding determines the size, and honing improves the shape.

The difference between honing and grinding is not always distinct. Some grinders have complex movements and are self-truing, and some honing machines are equipped with in-process gaging for size control. Many through-feed grinding operations rely on the same averaging effect as honing. Since honing is a relatively expensive manufacturing process, it can only be economically justified for applications that require very good form accuracy. The improved shape after honing may result in a quieter running or higher precision component. The flexible honing tool is a relatively inexpensive honing process.

This tools produces a controlled surface condition unobtainable by any other method. It involves finish, geometry and metallurgical structure. A high percentage plateau free of cut, torn and folded metal is produced.
