Mixed ultra-hard abrasive honing stone
Technical Field The invention relates to a hybrid ultra-hard abrasive honing oilstone and method for preparing the same. Background Art Honing is under the low cutting speed, the finishing of the surface of the workpiece processing method, is that grinding processing of a special form. Honing processing as a surface of the inner hole machining accuracy and finishing method for reducing surface roughness, which can remove not only the machining allowance of larger, but also can improve size accuracy, geometric shape precision and reduce the surface roughness, is widely applied in the automobile, aviation, petroleum machinery, construction machinery and military industry, or in the finishing process of the parts. As a honing stone honing process of the most commonly used, is widely applied to the grinding processing. Honing the honing stone as the surface quality and the inner hole of the one of the main factors of honing efficiency, its abrasive characteristics and the grinding performance of the whetstone will have the most direct impact. The traditional single abrasive honing stone, because of its single grinding characteristics, for some difficult-to-machine material (such as stainless steel, a titanium alloy, and the like), the grinding effect is not very satisfactory, there are certain limitations on use. Although stone honing oil imported foreign overall generally have a uniform wear, long service life, the LED, grinding processing performance, and the like, the cost of the expensive, however, limit the application of the enterprise. To this end, the invention has developed a model of using mixed abrasive material and at the same time super-hard abrasive honing stone, honing stone has the sharp grinding, the grinding efficiency and high quality of the grinding, the grinding time is short, long service life, self-sharpening optimum, process cost is low, it is simple and convenient to prepare, and the like. The honing stone can replace the traditional single abrasive honing stone, but also can replace imported from foreign countries excellent grindability of the honing stone, the process cost is greatly reduced.
