The zirconia ceramic sleeve is a core member of the optical fiber adapter and components RECEPTACLE. 2000 international Kyocera (Kyocera), Toto (Toto),abrasive tools, several Japanese companies to master zirconia ceramic sleeve complete production technology, Japan has not been to our transfer zirconia ceramic sleeve technology.
With domestic optical communication market development the ceramic sleeve growing demand, in order to reduce costs and increase the competitive advantage of their products, the country pay attention to the localization of the zirconia ceramic sleeve, so the "Tenth Five" national "863" zirconia ceramic sleeve massive domestic technology in high-tech development plan, "fiber ceramic ferrule connector with zirconia powder" and "Fibre for connectors support. State Key Laboratory of Shanghai Institute of Ceramics, Tsinghua University ceramic domestic units engaged in the study of zirconia sleeve.
After several years of development, the domestic enterprises and research units have mastered the precision machining of ceramic zirconia powder to the casing complete production technology. The technical progress of the ceramic sleeve is mainly reflected in the substantial increase of the quality of the zirconia nano-powder and zirconia ceramic sleeve reduce breakage during use and life improved. Nano-zirconia materials used for manufacturing ceramic ferrule and sleeve has long been Japan's monopoly, Japan Tosoh Corporation and Sumitomo Osaka Cement Company production of zirconia powder with high purity, low sintering temperature, high-density, high material strength In the past, our production quality zirconia powder with a wide gap between Japanese products Friends of can not be used in the production of the ferrule and sleeve. Failed zirconia powder production ceramic ferrule or sleeve, long-term use of the product, the ferrule end face of the rough, so that the the ferrule insertion loss significantly increase; while the casing on the decline of strength due to aging, sets tube breakage.
Over the past decade, China's zirconia ceramic sleeve production capacity, production technology and product quality has been a very large increase, domestic zirconia powder improving the quality of raw materials, to promote the localization of the ceramic batch and fully grasp the ferrule sets The tube full precision machining production technology, product quality has basically reached the level of Japanese products, various types of domestic ceramic casing production optical communication adapter fully meet the needs of a variety of occasions from high-end to low-end.cutting wheel
Wheel dressing should be timely, coarse grinding wheel to trim coarse, fine grinding grinding wheel should always be kept sharp to avoid overheating burns. Corner on both sides of the grinding wheel after dressing allowed burr.
Low surface roughness grinding, coarse fine grinding, fine grinding margin generally stay preferably 0.05 mm, can be left 0.1 mm workpiece clamping error.
Grinding process must be cooled sufficiently to take away a lot of grinding heat and erosion, and to prevent the grinding wheel the blockage and workpiece surface burns. Coolant must be clean, not mixed with debris or sand, to avoid workpiece nap. The cooling liquid of the grinding of stainless steel, generally used in the cooling performance of the preferred emulsion, or containing the extreme pressure additive and a small surface tension of the cooling liquid. The flow rate is 20 ~ 40 L / min, the grinding wheel diameter is large, 80 L / min.flap wheel
Stainless steel grinding allowance should take a small diameter cylindrical grinding, grinding allowance of 0.15 ~ 0.3 mm, fine grinding margin of 0.05 mm. Basically the same margin of internal grinding and cylindrical grinding. Surface grinding on a small area of ??the rigidity of good parts, the the unilateral left margin of 0.15 to 0.2 mm, poor rigidity, large area parts, unilateral stay grinding allowance 0.25 ~ 0.3 mm.
