C word processing is the screw holes with the main technology content, its processing of a direct impact on the clamping screw in the clamping and loosen the normal movement when. In the C word clip of the production process, the C word clamp screw holes as the main content of the processing technology, in general are two sets of different drilling on the processing, pack, discharge twice. And one can only processing a hole. So, not only affect machining precision and the processing efficiency is low, the intensity of labor is also big. So, need to design more spindle drilling machine, also need to design of progressive hole processing fixtures equipment. And turned in the desktop of progressive drilling, tapping the design of the automatic equipment, progressive must stop type turntable and drilling, tapping fixture design as the main content. This paper summarizes the basic definition and processing turntable for domestic and foreign some important producers results. The second part of the paper is that the thought of three solutions to these solutions and analyzes and compares their advantages and disadvantages. In each other after compa
