What is the Lapping and Define the Process?
Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive grinding stone or grinding wheel against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but can also improve the surface finish. … Meer weergeven Honing uses a special tool, called a honing stone or a hone, to achieve a precision surface. The hone is composed of abrasive grains that are bound together with an adhesive. Generally, honing grains are … Meer weergeven • Bore honing • Flat honing • OD honing / Super Finish / Fine Finish (taper and straight) Meer weergeven 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. Meer weergeven The plateau finish is one characterised by the removal of "peaks" in the metal while leaving the cross-hatch intact for oil retention. The plateaued finish increases the bearing area of the finish and does not require the piston or ring to "break in" the cylinder walls. Meer weergeven Since honing stones look similar to grinding wheels, it is tempting to think of honing as a form of low-stock removal grinding. Instead, it is better to think of it as a self-truing grinding process. In grinding, the wheel follows a simple path. For … Meer weergeven Since honing is a high-precision process, it is also relatively expensive. Therefore, it is only used in components that demand the highest level … Meer weergeven A "cross-hatch" pattern is used to retain oil or grease to ensure proper lubrication and ring seal of pistons in cylinders.
