英语翻译
Virtually any lubricant or coolant,or none at all,can be used in machining the alloys; in many cases,they respond well to ordinary sulfurized mineral oil.Sulfur imparts improved lubricity and anti-weld properties and is also believed to provide better chip action by embrittling the metal surface layer during chip formation when the tool edge metal interface temperature becomes high enough.

事实上任何滑润剂或散热剂、或什么也不用,都适用于合金的机械加工; 许多情况下,用普通的硫化矿物油反响就不错.加入硫磺可提高润滑和抗焊缝性能,并且人们还认为,当切削刃金属接触口温度变得足够高时,在切屑形成期间,可以通过使金属表层变脆来提供更好的切屑操作.
