铸件的表面光洁度,不仅是外观问题,而且还会影响机器的使用效果.因此,对铸件表面质量,必须提出明确的要求.目前国内铸件质量标准中,缺少统一的表面光洁度标准样块。这样,用户无法表达对铸件表面质量的要求,制造者及检验者之间也没有互相理解和共同遵循的基础.为了改变这种情况,我们纺机系统制造了行业内试行的样块.试制前,我们对国内外样块进行了比较分析,现简介如下:
Casting surface finish is not only the appearance of the problem, but also affect the use of the machine. Therefore, the castings surface quality, must make clear requirements. At present, the quality of castings in the country, the lack of uniform surface finish standard samples. In this way, the user can not express the requirements of the surface quality of castings, the manufacturer and the testers also do not understand each other and the basis for mutual compliance.In order to change this situation, we textile machinery system to create a pilot sample in the industry. , We conducted a comparative analysis of domestic and foreign samples, are as follows:
