1, the whole grinding process

tool with sealing ring surface very well together, to cater to the surface of tool edge makes complex ground movement. Hung between the tool and sealing ring surface coarse wax, when the tool and the sealing ring surface relative speed, part of the coarse wax frosted particles between the tool and the sealing ring surface drag or flip, cut to the sealing ring on the surface of a layer of metal material is too thin. Convex peak part of the sealing ring surface grinding out first, then gradually do rules of geometry.

grinding is not but the mechanical wear of metal materials processing and manufacturing process, but there are also the chemical effect. The plant oil can make in the slack wax is air oxidation film production and processing surface, thus sped up the whole grinding process.

2, grinding movement

tool with sealing ring surface relative speed, the seal ring on the surface of each point of the tool relative sliding road and should be the same. Moreover, relative speed of the bearing should be continued for change. Continuous movement azimuth changes left frosted each particle size is not easy in the sealing ring surface repeated its trajectory, to prevent lead to significant scratches and improve the surface roughness of the sealing ring surface. In addition, sports orientation as the change of breaking can't slack wax over relatively well-balanced, and is symmetrically cut sealing ring surface of the metal materials.

although multifarious grinding movement, movement azimuth although big changes, but the grinding motion from beginning to end is along the tool and cater to the surface of the sealing ring surface. Whether manual grinding or milling machinery equipment, sealing ring surface geometry appearance accuracy is the key tool geometry accuracy and the harm of ground motion.

3, grinding rate

the faster the rate of grinding movement, the grinding efficiency is also higher. Grinding speed faster, in unit time products based on workpiece surface grinding sand particles is more, cutting metal materials also.

4, grinding work pressure

grinding efficiency along with the expanding of grinding pressure, grinding work pressure can not be too large, generally is 0. 01 ~ 0. 4MPa。

grinding cast iron, copper and martensitic stainless steel plate surface, grinding work pressure of 0. 1 to 0. 3MPa； Hardened steel and carbide tool surface is 0. 15 ~ 0. 4MPa。 Coarsely ground of great value, when the fine grinding of smaller value.
