1.现状加工过程中使用的冷却液有乳化油和透明冷却水(由亚硝酸钠、碳酸钠、甘油组成),无论从清洗性、还是从防锈性方面都存在着严重不足,表现在加工过程中屡屡发生批量锈蚀。板牙铲前后梢和丝谁磨钩的表面粗糙度Ra均要求0.8以上,由于种种原因,板牙梢面和丝维前角经常出现边加工边发黄的现象,速度之快可以在5秒钟内发生,这些局部发黄产品只有报废,因而不时出现同类机床的停工停产,影响产品的正常流通,造成不应有的损失。例如直柄钻头磨尖是最后工序,生锈比例最大,需酸洗除锈,还易造成新的隐患——氢
1. The status quo The coolant used in the process is emulsified oil and transparent cooling water (composed of sodium nitrite, sodium carbonate, glycerin), both from the cleaning and rust-proof aspects of the existence of a serious lack of performance in the processing Batch rusting occurs frequently in the process. Because of various reasons, the flank surface and the anterior horn of the filiform often appear yellowing while processing, the speed can be fast within 5 seconds Occurred that these local yellowing products only scrapped, so from time to time similar machine downtime, affecting the normal circulation of products, resulting in undue losses. For example, straight shank bit sharpening is the final process, the largest proportion of rust, pickling rust, but also easily lead to new hidden dangers - Hydrogen
