熔模铸造能制造出形状复杂、尺寸精度较高的铸件。它是机械制造生产中一项很重要的少无切削工艺。随着机械工业的飞速发展,对熔模铸件尺寸精度的要求也相应地提高,那么如何确定熔模铸件的尺寸精度呢? 为了确定熔模铸件合理的尺寸精度,国内、外熔模铸造工作者做了大量的试验研究,也得出了一些极为宝贵的数据和资料。作者在参加编制“第一机械工业部凿岩机械与气动工具结构钢熔模铸件通用技术条件”过程中,参
Investment Casting to create a complex shape, high dimensional accuracy of the castings. It is a very important machine-less production of non-cutting process. With the rapid development of machinery industry, the requirements on the dimensional accuracy of investment casting are correspondingly raised. How to determine the dimensional accuracy of investment casting? In order to determine the reasonable dimensional accuracy of investment casting, domestic and foreign investment casting workers Do a lot of experimental research, but also come to some very valuable data and information. The author participated in the preparation of “First Ministry of Machinery Industry, drilling machinery and pneumatic tools structural steel investment casting general technical conditions” process, the reference
