项目摘要

Conventionally, advanced ceramics parts used to be finished mainly by lapping processing with diamonds slurry. This study intends to develop a flat honing processing of the new material parts with diamond lapping film which could be expected to be effective tool for the automation of lapping operations. As the first step, basic honing characteristics were investigated with the two types of diamond lapping film, i.e.,roller coated one and electrically plated one. As the results, their lapping characteristics on efficiency, surface accuracy, tool wear and so on are made clear experimentally. Most of all, by comparing the diamond lapping film with the usual GC lapping film, the diamond lapping film is confirmed to be excellent in its lapping ability.This year, new types of diamond films, i.e., roll formed one and electrically cast one, are adopted for the test and compared with the ones investigated last year. The results obtained suggest that the new type of roll formed diamond film should be the most promising lapping film. The main features of the roll formed diamond film are summarized as follows; (a) The tool life of the roll formed diamond lapping film is far longer than the usual coated one. The former has also such merit that it can be trued or dressed to generate new working surface. (b) The lapping characteristics of roll formed one are clarified by systematically arranged experiments. Based on these results, reasonable lapping systems are designed.

传统上，先进陶瓷零件的精加工主要采用金刚石浆料研磨加工。本研究旨在开发一种带有金刚石研磨膜的新材料零件的平面珩磨加工方法，有望成为研磨操作自动化的有效工具。第一步，研究了两种类型的金刚石研磨膜（即辊涂膜和电镀膜）的基本珩磨特性。结果，通过实验明确了它们在效率、表面精度、刀具磨损等方面的研磨特性。最重要的是，通过将金刚石研磨膜与普通GC研磨膜进行比较，证实金刚石研磨膜具有优异的研磨能力。今年，采用了新型金刚石膜，即滚压成型和电铸膜进行测试，并与去年研究的金刚石膜进行了比较。所得结果表明新型滚压金刚石薄膜应该是最有前途的研磨薄膜。滚压金刚石膜的主要特点总结如下： (a) 滚压金刚石研磨膜的刀具寿命远远长于通常的涂层金刚石研磨膜。前者还具有可以进行修整或修整以产生新的工作表面的优点。 (b) 通过系统安排的实验阐明了滚压成型件的研磨特性。根据这些结果，设计了合理的研磨系统。
