过去,我厂在车床上粗车泵轴时,经常打刀、切屑不断乱缠乱窜很不安全,影响了产品质量和生产效率的提高。我们在学习兄弟单位先进经验的基础上,又进行了实践、研究,搞成了一把机械夹固小月牙洼断屑车刀。这种刀具结构简单、夹固牢靠、刀片利用较为合理,刃磨与使用方便、断屑规则 In the past, I plant roughing pump shaft in the lathe, often hit the knife, the chip constantly chaos chaos channeling is not safe, affecting the product quality and production efficiency. On the basis of studying the advanced experience of our brother units, we conducted a series of experiments and studies, and became a mechanical small-crescent-tooth-chip-breaking lathe. This cutter has the advantages of simple structure, firm clamping, more reasonable blade utilization, easy sharpening and easy operation, chip breaking rules
