影响加工表面光度的有各种因素。润滑的冷却火不过是其中之一。苏联科学研究学会对于润滑的冷却液的功效,会做过多次试验,兹介绍试验的内容于下: (一)用三种不同钢,(a)С .3──代表低碳钢;(b) 7A──代表工具钢;( c)ЭИ107──代表耐热钢。 (二)用五种不同润滑的冷却液(1)?
There are various factors that affect the luminosity of the machined surface. Lubrication of the cooling fire is but one of them. The Society for the Study of Science of the United States will do more than one test of the effectiveness of lubricated lubricants. The following is a description of the test: (i) three different steels, (a) С .3── for mild steel; ( b) 7A ─ ─ on behalf of the tool steel; (c) ЭИ107 ─ ─ on behalf of heat-resistant steel. (B) with five different lubricants (1)?
