1, the definition of different
Grinding use of abrasive particles coated or pressure embedded in the grinding tool, through the grinding tool and the workpiece under a certain pressure of the relative movement of the surface of the processing of the finishing process (such as cutting).
Honing (háng mó) is set in the honing head of the oil stone (also known as honing bar) on the finishing surface of the finishing process. Honing and hole surface contact area is larger, processing efficiency is higher.
2, different methods
Honing, the workpiece is mounted on the honing bed or fixture, with a number of oil stone honing head inserted into the hole has been processed, driven by the machine tool spindle rotating and axial reciprocating motion. Oil stone strip with a certain pressure and hole wall contact, can cut off a layer of very thin metal. Honing head and spindle generally into a floating coupling.
Grinding cylindrical generally in fine grinding or fine turning basis. Manual grinding cylindrical can be carried out on the lathe, the workpiece and the research tool coated with abrasive, the workpiece is driven by the lathe spindle rotation, research tool with hand support for axial reciprocating movement
3, different characteristics
Honing processing is a workpiece processing surface to achieve high precision, high surface quality, high life of a highly efficient machining method, can effectively improve the dimensional accuracy, shape precision and reduce Ra value, but can not improve the positional accuracy of holes and other surfaces
Grinding equipment is simple, precision requirements are not high, and the processing quality is reliable. Can obtain very high precision and very low Ra value. But generally can not improve the positional accuracy between the machined surface and other surfaces.
