摘要

当工件要求严格的公差或良好的表面光洁度时，磨削通常是最好的解决方案。然而，这一过程的特点是产生大量的热量，需要控制。最小量润滑(MQL)系统作为洪水冷却系统的替代方案出现。然而，前者在等温球铁(ADI)表面磨削中的应用仍然是一个未探索的话题。本研究旨在通过实验研究MQL在不同表面磨削条件下ADI样品表面形貌的适用性以及砂轮转速和工作速度的影响。获得ADI表面形貌，确定粗糙度参数和表面硬度变化。结果表明，MQL在ADI表面磨削中的应用是可行的。表面粗糙度与冷却系统相似，表面硬度变化较小。

Experimental study of MQL applicability in ADI grinding and its influence on surface topography

ABSTRACT When workpieces require tight tolerance or a good surface finish, grinding is usually the best solution. Yet this process is characterised by generating a great amount of heat that needs to be controlled. The minimum quantity lubrication (MQL) system emerged as an alternative to the flood cooling system. Nevertheless, the employment of the former in austempered ductile iron (ADI) surface grinding is still an unexplored topic. This research seeks to experimentally study the applicability of MQL and the influence of the wheel speed and workspeed, in the surface topography of ADI samples subjected to different conditions of surface grinding. ADI surface topography was acquired, then the roughness parameters and surface hardness alterations were determined. The results show that the application of MQL in ADI surface grinding is possible. The surface roughness is similar to that of the flood cooling system and the surface hardness alterations are small.

期刊介绍： The International Journal of Cast Metals Research is devoted to the dissemination of peer reviewed information on the science and engineering of cast metals, solidification and casting processes. Assured production of high integrity castings requires an integrated approach that optimises casting, mould and gating design; mould materials and binders; alloy composition and microstructure; metal melting, modification and handling; dimensional control; and finishing and post-treatment of the casting. The Journal reports advances in both the fundamental science and materials and production engineering contributing to the successful manufacture of fit for purpose castings.
