We study the influence of modification on the structural-phase state of 38KhN3MFA steel and the morphology of chips formed in the course of turning of billets at a rotation speed of 315 rpm under dry conditions, in the presence of water, and with lubricoolants. It is shown that, in the case of application of lubricoolants, the sizes of chips decrease, their shape becomes more compact and folded, and the roughness of the treated surface becomes ten times lower than after dry turning.

38khN3MFa钢变质对变工艺条件下结构相态及切削产品的影响

我们研究了变质对 38KhN3MFA 钢结构相状态的影响，以及在干燥条件下，在有水和润滑剂的情况下，以 315 rpm 的转速车削钢坯过程中形成的切屑形态。结果表明，在使用润滑冷却剂的情况下，切屑的尺寸减小，它们的形状变得更加紧凑和折叠，处理后的表面粗糙度比干车削后低10倍。
