The early history of the development of ceramic cutting tools in 1912- 1913. Britain and Germany have emerged alumina ceramic tool (but patented ceramic tool made by the German company Degussa in 1938). Application in Production began in 1950 year. Because of its strength, toughness is low. Over a longer period is limited to do with the continuous cutting finishing. And the cutting speed and feed rate are low. Until 1968 it appears the second generation of ceramic cutting tools - alumina composite tool in the strength and toughness of the tool has been significantly improved compared to the alumina various parts can be cut at higher speeds and a larger amount of feed at. . it has been more widely used. The late 1970s and early 1980s there has been an international third generation ceramic tool - silicon nitride ceramic tools. Such ceramic cutting tools have a higher quality than composite aluminum tool toughness, impact resistance, high temperature strength and thermal shock resistance. Ceramic inserts in various industrial production in developed countries is growing rapidly. China since the 1960s and began mass production of complex aluminum blades. The current annual production capacity of 14-15 million. Silica ceramic blade began to study since the mid-1970s, though because of poor performance. Can not meet demand. In recent years. With the study of high-temperature structural ceramics deepening Increases performance silicon nitride ceramic has been greatly improved. So that the silicon nitride ceramic tool developed rapidly in our country. Imported ceramic bearings price in today's world famous bearing company both in the development, production of ceramic bearings and ceramic ball bearings, and the level of quality of the product, has become the measure of its business strength is an important symbol. According to incomplete statistics, so far, yet easy to use ceramic knife, ceramic bearings can be produced abroad are: the United States, Japan, Germany, France, Russia, South Korea, Britain and other countries. Wherein the ceramic ball bearing production in foreign countries started earlier, the use of a wider range of occasions, such as CNC machine tools with ceramic ball bearings, grinding electric spindle with ceramic ball bearings, machine tool ball screws with ceramic ball bearings. Ceramic ball bearing high wear resistance, self-lubricating, high speed and other performance has been brought in to play, but also for high-precision machine tools, high-speed machine tools, special environmental equipment contributed. As a core component of ceramic ball bearings - ceramic spheres, secondly, ceramic bearings and ceramic ball bearings production and industrialization of high-tech ceramic bearing manufacturing technology combined, both are very high degree of specialization, ceramic knife, if not addressed ceramics and bearing industries combined problems and achieve high-volume, low-cost production, ceramic tool prices to meet the market demand is just empty talk. Now, what is a good brand of ceramic knife, able to produce bearings that can not manufacture ceramic material, capable of producing enterprise manufacturing ceramic materials not bearing between professions and disciplines serious gap in the practical application, the current number of bearing manufacturers of ceramic bearings and ceramic ball bearings in the professional knowledge, especially ceramic materials science and engineering research is relatively small, it is well known that the surface content of ceramic bearings and ceramic ball bearings. Created a ceramic material made of ceramic bearings bearing is added ceramic ball bearings with ceramic balls that situation. Domestic ceramic bearing and ceramic ball bearings can in corrosion resistance, electrical insulating, under absolutely magnetic, low-speed, light-load environments. There is the presence of large domestic manufacturers of ceramic material problems at the process and the technology has not yet pass the premise, the blind pursuit of low prices caused by the material properties can not achieve the desired effect ceramic tool prices, Chen Feng Hardware (certification) ceramic knife provided by the Dongguan City Hardware Co., Ltd. Chen Feng. Dongguan City, Chen Feng Hardware Co., Ltd. (www.chenfengdg.com/) is a professional, "metal stamping, kitchen knives, injection molding, CNC machining, automotive interior parts" of the company.
