Since the 21st century, the modern manufacturing technology and manufacturing process automation machinery have seen significant development. But tools (including fixtures, tools, Tools and assistive device, etc.), not in innovation, its functions are still very significant. Fixture processing machine parts on the quality, productivity and product costs have a direct impact. Therefore, whether in traditional manufacturing or modern manufacturing systems, fixtures and equipment is an important process. Is a fixture on the workpiece can be certain that the technical requirements of accurate positioning and firmly stepped up the process and equipment; it is widely used mechanical processing, testing and assembly of the entire process. In the modernization of machinery and equipment manufacturing industry, improve processing accuracy and productivity, lower manufacturing costs, has been by the manufacturers pursuit of the goal. The design and correct and rational use of fixture is to ensure that the processing quality and improve productivity to reduce the cost of one of the important technical aspects, but also to expand the scope of use of all types of machine tools than indispensable. In this paper, the C620-1 will be transformed into dual-use processing mill cars can be equally dedicated ball machine; machine dedicated to the processing of the different sub-ball size to the size of different parts processing, and only sub- conditioning on the screws and replaced compatible child seat. This paper introduces the machine fixture composition, characteristics and the development of the status quo, at the same time analyzing the machine fixture different role. The main thing is to C620-1 cars can be transformed into sub-processing mill dual-use the ball machine for the whole process, cars and other sub-components consisting of Waterloo fixture design and modular fixture assembly precision and attention to the matter. Study spherical processing technology and the application of special fixture. This paper presents the processing sub-Waterloo dedicated fixture overcome before cars can use the same grinding machine disadvantages. In this paper the design and installation of the lathe spindle special fixture to achieve more equally, multi- center, a series of spherical diameter machining. Hole and put the ball touting Cage Die Programme for the production of small quantities variety, are in sub-Waterloo, in the lathe processing requirements. The results show that: C620-1 cars can be transformed into sub-processing mill dual-use the ball machine for the special fixture jig grinders and more obvious advantages: simple structure, high precision, high universality and easy to use, etc.. Key words: modern manufacturing technology, and machine tool fixture, grinding dual-use vehicles, and other sub-Waterloo dedicated fixture
