有许多因素影响切削液的使用寿命,本文主要从过滤切削液、控制水的质量、控制切削液的温度和定期检测切削液等加以论述。 一、过滤切削液 无论何种切削液,过滤都是延长其使用寿命的有效方法。由于切削液循环使用,所以在切削液中不可避免地存有某些杂质,这些杂质包括切屑、灰尘、磨料粉粒、纤维、游离的杂油、切削液中的空气和水等。继续使用存有这些杂质的切削液,首先有损于刀 相似文献

随着机械加工业向高速、强力、精密等方向的迅速发展,对金属切削液提出了越来越高的要求。特别是20世纪80年代以来,由于人们对生态环境意识的进一步强化,对金属切削液又增加了环保要求。水基合成切削液具有优异的冷却、清洗作用和良好的环境指标,将逐渐取代切削油和乳化液,占据切削液的主导地位。然而,水基切削液水分含量高,使用时易引起加工设备及工件的锈蚀,因此如何选择高效缓蚀添加剂显得特别重要。过去大量使用水溶性金属缓蚀剂基本为亚硝酸型,由于该品对 相似文献

硬水对水基切削液的危害 总被引:1,自引:0,他引:1
随着现代切削加工技术的发展,作为工艺配套材料的切削液日益引起人们的重视。由于水基切削液具有优良的冷却性能,高的生产效率和低的生产成本,因而得到广泛的应用。水基切削液包括合成切削液、半合成切削液(也称微乳状切削液)和乳化液。在使用时,需要将浓缩液用水配制成高水基的稀释液。但在配制稀释液时人们往往对所用水的水质重视不够,使用硬水配制,造成切削液质量下降,加工成本增加,给使用带来麻烦。本文建议使用去离子水来配制水基切削液。 相似文献

Cutting fluids have seen extensive use and have commonly been viewed as a required addition to high productivity and high quality machining operations. Cutting fluid related costs and health concerns associated with exposure to cutting fluid mist and a growing desire to achieve environmental sustainability in manufacturing have caused industry and academia to re-examine the role of these fluids and quantify their benefits. This work summarizes the traditional purposes of cutting fluids and reports on recent analytical and experimental research to critically examine these functions. To minimize or even eliminate the concerns associated with cutting fluid usage, several recent and novel approaches have been proposed and are examined. 相似文献

Metalworking fluids play a significant role in machining operations and have a substantial impact on tool life, shop productivity, and the quality of the workpiece. The results presented in this article show the influence of the properties of the metalworking fluids and the supply system on the workpiece quality in cutting and grinding processes. Chemical, physical, and tribological aspects have an impact on the properties of the generated surface. For the assessment of cooling effectiveness, a special test rig for the investigation of the coolant supply system in a grinding process is presented. Another approach to investigate the effectiveness and efficiency of the cooling and lubrication system during grinding is to monitor the temperatures and forces by a wheel-based measurement using telemetric data transmission. A further important aspect of water-soluble metalworking fluids is the influence of microbial effects on working results in machining. Microbial degradation leads to drastic changes in the physical and chemical properties of the metalworking fluid during service life. Besides the demands on the efficiency and economy of cutting processes, their environmental friendliness becomes a crucial issue itself. Therefore, an example for a holistic view on the environmental impacts of machining processes and the application of metalworking fluids is given. 相似文献

The question of whether machining operations and exposure to water-base cutting fluids constitutes a human health problem is complex. The literature on the subject is hard to find; it is difficult to create study groups of workers large enough to develop statistically significant information; there is often a lag phase of several years between exposure to cutting fluids and the appearance of a medical problem; public attitudes restrain research on the subject; the identity of the chemicals involved is not completely known and animal studies involving cutting fluids are not adequate at present. Until adequate information is available, efforts should be directed towards minimizing exposure and controlling the microbial loads found in these products. 相似文献

Cutting fluids re receiving increasing scrutiny owing to the potential negative health and environmental consequences of their usage. Manufacturers are besieged with many claims by cutting fluid suppliers and historically fluids have often been selected based on non-technical reasons. A methodology for the development of a classification scheme based on the physical properties of a wide array of cutting fluids is presented. The method of cluster analysis, in a hierarchical agglomerative form, is used to identify differences between fluid samples and a case study example employing this method is used to illustrate the capability of the approach. Results of the example point to unanticipated fluid distinctions and demonstrate the potential for the technique to adequately define cutting fluid categories. 相似文献
