罗耳斯·罗伊斯公司精铸厂生产发动机铸件合格率高,质量优异。铸出的叶片型面无加工余量,一般结构件除配合面外均为无余量。他们除蜡模和制壳车间有恒温控制并采用了一系列新工艺新技术外,还相应地配置了一批较实用、性能较好的非标准设备。这类设备有下面几个特点:1)采用单机自动控制。如压蜡、制壳、渗色检验等设备其主要工艺参数均采取程序自动控制,使生产过程中每批产品的工艺参数一致,保证了质量,提高了劳动生产率,减轻了劳动强度。2)自
The production of engine castings by the company of the Rolls-Royce Casting Company has a high pass rate and excellent quality. Casting blade surface no machining allowance, the general structure of parts in addition to outside with no margin. In addition to wax mold and shell workshop temperature control and the use of a series of new technology and new technology, but also the corresponding configuration of a number of more practical, better performance of non-standard equipment. Such equipment has the following characteristics: 1) using stand-alone automatic control. Such as pressure wax, shell, bleed test equipment and other equipment are the main process parameters are automatically controlled, so that each batch of products during the production process parameters to ensure quality, improve labor productivity and reduce labor intensity. 2) since
