我厂磨床磁力卡盘上加工轴承套圈用的支撑块,以前用聚四氟乙烯棒制做,成本高,货源缺,经常影响生产。从价值工程V=F/C可知,在满足功能要求的前提下,应尽量降低成本,为此,我们找了性能相近的几种材料进行实验,发现用普通尼龙6和铸型尼龙6,除能较好满足各种基本功能要求外,使用寿命成倍提高。在此基础上我们对普通尼龙6、铸型尼龙6及聚四氟乙烯从寿命和成本上进行了比较如下表:从下表看出铸型尼龙6是理想的代用材料,且货源充足,采
I plant grinder magnetic chuck processing bearing rings with the support block, the previous system made with Teflon rods, high cost, lack of supply, often affect the production. From the value of the project V = F / C shows that in meeting the functional requirements of the premise, we should try to reduce costs, for which we find the performance of several similar materials to experiment and found that with ordinary nylon 6 and nylon 6 mold, in addition to Can better meet the various basic functional requirements, the service life increased exponentially. On this basis, we compared the ordinary nylon 6, nylon 6 and PTFE Teflon from the life and cost are as follows: From the table below, casting nylon 6 is the ideal alternative material, and adequate supply, mining
