项目摘要

The high removal rate ultra-smoothness grinding method which can finish to almost the same smoothness formed by polishing has been recently desired strongly for high efficiency production of high quality components. From the point of view, in the previous report, the existing of limiting smoothness, which can be attained in traverse grinding is discussed theoretically and presented experimentally. On the results, the newly devised ultra-smoothness grinding method based on the new concept is proposed and ascertained to be useful for finishing near the ultra-smoothness surface. The removal rate obtained using horizontal surface grinding, however, is small though the rate is larger than lapping and polishing.To make the removal rate much larger, in the research, the rate in ultra-smoothness grinding method is analyzed firstly in the case of horizontal surface grinding. Based on the analysis, the new type of vertical surface grinder is designed and manufactured on trial. The two kinds of v … More ertical grinders are manufactured. One is reconstructed from the conventional vertical grinder with the disc type of table. The other is newly manufactured and has the ultra-high revolution spindle and the four columns for the high removal rate grinding and high rigid mechanism. Accompanying with the manufacturing, the basic research on the supplying effect of grinding fluid and ultra-high depth of cut of grinding is investigated using the horizontal grinder. In addition, in order to examine the grinding wheel surface condition quickly and precisely, the automatic image processing system is developed. The main conclusions are as follows :(1)Comparing with the horizontal grinder, the two types of the newly manufactured vertical is useful for the ultra-smoothness grinding in much higher removal rate.(2)The type and dilution of grinding fluid have the large influence on the ultra-smoothness grinding of silicon carbide ceramic.(3)Comparing with the conventional grinding method, the newly developed ultra-smoothness grinding method enables the much higher depth of cut of ultra-smoothness grinding.(4)The newly developed automatic image processing system for evaluating the wheel surface condition is available for pursuing quantitatively the wheel conditions in a series of grinding operation processes, that is, truing process, dressing process and grinding process including the grinding process in the occurrence of loading.

最近，人们强烈希望高质量的高质量组件生产高效率，而高质量的高效率是高质量产生的高度平滑度磨削方法，该方法可以完成几乎相同的平滑度。从上一份报告中，从理论上讨论并在实验上讨论了可以在遍历磨削中参加的限制平滑度的现有现有的。在结果上，提出了基于新概念的新设计的超平滑度研磨方法，并确定可用于在超平滑度表面附近完成。但是，使用水平表面研磨获得的去除率很小，尽管速度大于收获和抛光率。为了使去除速率大得多，在研究中，在水平表面磨削的情况下，首先对超平滑度研磨方法的速率进行分析。基于分析，新型的垂直表面研磨机采用试验设计和制造。两种V…更精细的研磨机是制造的。一个圆盘类型从传统的垂直研磨机中重建。另一个是新制造的，具有超高的革命主轴以及高移除速率磨削和高刚性机制的四列。伴随着制造业，使用水平磨床研究了关于磨油和超高磨削深度的供应效果的基础研究。此外，为了快速，准确地检查磨削轮的表面状况，开发了自动图像处理系统。主要结论如下：（1）与水平磨床进行比较，新生产的垂直行业的两种类型可用于更高的去除速率的超平滑度。（2）磨削流体的类型和稀释性具有很大的影响，对硅质的超平滑剂磨牙的影响很大。（4）新开发的自动图像处理系统，用于评估车轮表面状况的新开发的自动图像处理系统可实现磨削方法的更高深度。可用于定量地在一系列的磨削操作过程中进行定量的轮子条件，即，即磨削过程，饰物过程，敷料过程和磨削过程，包括负载的磨削过程。较少的
