Abstract

Novel composite system was developed, including real time force and temperature monitoring devices and minimum quantity lubrication (MQL) system. During MQL grinding, grinding force, temperature, blockage of a grinding wheel, surface roughness Sa and specific grinding energy are 0.9 N, 24 ℃, 15.49 %, 0.227 μm and 15.08 J/mm³ respectively, reducing 84.21 %, 51.81 %, 75.4 %, 88.4 % and 80 % correspondingly, compared with those of dry grinding. A motion model of single grain is proposed, and geometric contact arc length calculated is 44.76 μm. At optimal feed rate of 200 mm/min, the maximum and critical undeformed thicknesses of a chip are 0.05 and 2 μm, respectively. Infrared spectroscopy shows that crosslinking grid of cyanate ester was broken, and short-chain was formed on ground surface.

利用开发的新型复合体系实现对氰酸酯的优异研磨性能

开发了一种新型的复合系统，包括实时力和温度监测装置和最小量润滑系统。MQL磨削时，磨削力、温度、砂轮堵塞、表面粗糙度Sa和比磨削能分别为0.9 N、24℃、15.49 %、0.227 μm和15.08 J/mm3，与干式磨削相比分别降低84.21 %、51.81 %、75.4 %、88.4 %和80 %。提出了单颗粒的运动模型，计算出的几何接触弧长为44.76 μm。在最佳进给速度为200 mm/min时，芯片最大未变形厚度为0.05 μm，临界未变形厚度为2 μm。红外光谱分析表明，氰酸酯的交联网格断裂，在表面形成短链。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
