摘 要
采煤机直接用于煤炭的地下开采，是煤炭生产中最主要的机械设备之一。改革开放以来，我国的采煤机研发有了长足的发展，但在性能和可靠性上与世界先进国家的采煤机相比，还存在一定的差距。为此，开发高产高效矿井综合配套技术是我国煤炭科技发展的主攻方向。为提升产品设计质量，完善快速设计和个性设计手段，采煤机的创新设计尚需要加大研究力度。
MG250/591-WD型电牵引采煤机是在鸡西煤机有限公司多年研制电牵引采煤机成功技术的基础上开发制造成功的。我这次设计的主要任务是对MG250/591-WD型采煤机右截割部摇臂壳体进行加工工艺规程设计。创新之处在于在设计过程中根据具体情况应用了数控编程。

Abstract
Coal mining machine uses in the coal directly underground mining, is in the coal production one of most main mechanical devices. Since the reform and open policy, the coal mining machine research and development had the considerable development, But compares in the performance and in the reliability with the world advanced countries coal mining machine, also has certain disparity. Therefore, the development high production highly effective mine pit synthesis necessary technology is our country coal science and technology development main attack direction. In order to promote the product design quality, the consummation fast design and the individuality design method, the coal mining machine innovation design still needed to increase the research dynamics.
The MG250/591-WD electricity hauling coal mining machine is develops in the JiXi coal machine limited company many year development electricity hauling coal mining machine success technology foundation makes successfully. The author this design primary mission is carries on the processing technological process design to the MG250/591-WD coal mining machine right cutting department rocking shaft shell. Place of the innovation lay in the design process acts according to the special details to apply the numerical control programming.
Key words: Coal mining machine Processing technological process
