中文摘要:
加工中心由于备有刀库并能自动更换刀具,使得工件在一次装夹中可以完成多工序的加工。加工中心一般不需要人为干预,当机床开始执行程序后,它将一直运行到程序结束。加工中心还赋予了专业化车间一些诸多优点,如:降低机床的故障率,提高生产效率,提高加工精度,削减废料量,缩短检验时间,降低刀具成本,改善库存量等。由于加工中心的众多优势,所以它深受全球制造企业的青睐。
法兰,又叫法兰盘或突缘,使管子与管子相互连接的零件,连接于管端。法兰上有孔眼,可穿螺栓,使两法兰紧连。法兰间用衬垫密封。法兰管件指带有法兰的管件。它可由浇铸而成,也可由螺纹连接或焊接构成。法兰联接由一对法兰、一个垫片及若干个螺栓螺母组成。

外文翻译:CNC Machining Center with a knife as a result of the Treasury and can automatically replace the tool, the workpiece in a fixture to be completed in multi-processing processes. Processing centers do not require human intervention, when the machine after the beginning of the implementation process, it will have to run to the end of the process. CNC Machining Center workshop also gives some of the many advantages of specialization, such as: machine tools to reduce the failure rate, increase productivity, improve processing accuracy, reduce the waste volume and shorten the test time, lower tool costs and improve inventory and so on. Processing center as a result of the many advantages it by the favor of global manufacturing enterprises. Flange, also known as process flange or edge, so that the pipe and pipe parts connected to each other, connected to pipe end. There are hole flange can be bolted to wear so that the two flange abuts. With liner sealing flange between. Flanged pipe fittings refers to the pipe with a flange. It can be cast from, but also may pose a thread connection or welding. Flange connected by a flange, a gasket and nut composed of a number of bolts.
