The General Design of CA6140 lathe spindle box
Abstract: When the machine becomes production tools, as a sector of equipment basic supply industry, the prominent role that the machine tools palys is increasing clearly. In fierce market competition of the world, as the international flowing goods, the machine is changing with each passing dayl.Only to innovate independently, it can survive and develop in the market. China should develop advanced machine tools, the revitalize the machine tool industry firstly to revitalize the machinery manufacturing and achieve the industrial modernization. Machine tool industry plays very important role in the national economy, concerning all of industrial production of other categories, including automotive, chemical, aerospace, defense and other industries.it is not only the force of economic development, but also the important protection of the national security strategy. This article mainly about general design and layout drive of the CA6140 lathe spindle box. CA6140-precision lathe is the ordinary lathe, is used to turning to internal and external cylindrical, cone and other spin-face, turning all kinds of thread that metric or imperial, and module or pitch diameter, conducting drilling, reaming and pulling tanks and so on. Headstock mainly includes the spindle, the other axises and axis components and speed control and other components.
