四摩擦润滑状态对产品表面质量的影响由于压力加工制品在使用前,一般不再承受切削、研磨等后续工序,因此,表面质量显得十分重要。按加工过程中制品表面状态的变化,可以分为如下几种情况:①材料表面不受工具约束时,粗糙度的自由变化;②由于工具作用,材料表面凸起被“压熨”;③工具粗糙表面被压印到材料表面:④摩擦
Four friction lubrication on the surface quality of the product As the pressure processed products before use, generally no longer bear the cutting, grinding and other subsequent processes, therefore, the surface quality is very important. According to the process of product surface state changes, can be divided into the following situations: ① material surface free from tool constraints, the roughness of the free change; ② due to the role of tools, material surface bulge was “pressed iron”; ③ tools Rough surfaces are imprinted onto the material surface: ④ Friction
