透明石英玻璃厚壁管是拉制高质量石英玻璃(特别是光导纤维包层管的预制件,其制造技术关键之一就是要解决厚壁管的内圆表面(φ80×1500mm)加工问题。由于加工工艺的特殊要求,对于厚壁管内孔的圆度、锥度和表面粗糙度规定都比较严格,而对石英玻璃材质的深孔加工在国内尚无先例。现参照金属深孔加工技术决定采用深孔钻削和珩磨工艺解决此问题,并研制了适用的深孔钻削专用机床和卧式强力珩磨机床,试验选用了珩磨石英玻璃的切削参数。一、石英玻璃冷加工特点与脆性材料磨削机理
Transparent quartz glass thick-walled tube is drawing high-quality quartz glass (especially optical fiber cladding tube prefabricated, one of its manufacturing technology is to solve the thick-walled tube inner surface (φ80 × 1500mm) processing problems due to The special requirements of the processing technology, for the thick-walled tube hole roundness, taper and surface roughness provisions are more stringent, and deep processing of quartz glass material in the country there is no precedent for reference deep processing of metal deep processing technology is decided to use deep Hole drilling and honing process to solve this problem, and developed for deep hole drilling machine tools and horizontal strong honing machine tool, the test selection of honing quartz glass cutting parameters. First, the characteristics of cold-working quartz glass and brittle material grinding mechanism
