Advantage &Disadvantage Of Honing Process In Grinding
What’s The Advantages Of Honing?
Wide processing range.
Honing process is mainly used in the inner surface of steel pipe finishing processing, such as the bore cylindrical, steps, blind hole and cone hole, etc., as well as for plane, sphere and forming surface and cylindrical surface. Honing the aperture of 1 ~ 1200 mm or greater, hole length is 12000 mm. The honing process is suitable for almost all of the workpiece material.
Good surface quality.
After honing, the inner surface of the pipe is cross-shaped, which is good for the storage of lubricating oil and the maintenance of lubricating film. Moreover, the surface of the steel pipe does not produce burns, cracks, deterioration and hard layer because the grinding force and heat of honing is very small, and its speed is a few tenths of the general grinding speed.
High machining accuracy.
When honing the inner hole, the roundness and cylindricity can reach 0.005 ~ 0.01mm, and the surface roughness value Ra can reach 0.05 ~ 0.2m. Its machining efficiency is similar to that of grinding and can replace part of grinding process, but it can’t improve the position accuracy.
Low requirement for machine tool precision.
In addition to specialized honing machines, it can also be used on lathes, boring machines, and drilling machines.
In the process of honing, out-of-tolerance of hole size, improper whetstone, too low circular speed and too high reciprocating speed or other reasons can result in out-of-tolerance of hole roundness, size, straightness, rough honing surface, and even scratch. Now, the application of superhard abrasives such as synthetic diamond and cubic boron nitride has greatly advanced honing technology. Honing has been used not only as a final machining process with high precision requirements, but also as an intermediate process for removing large margins. Honing is an efficient and high-quality machining method.
