【正文】 stract The graduation design topic is the processing center pound chip breaker structure design. At present, machining center most widely practical automatic chip removal device is scraper chip this rejection chip chip removal efficiency is higher, row crumbs ability is stronger, and the region as a whole did not accumulate chip dead, and strong ability to adapt. However, the chip is not high, the smaller granular chip is easy to cut into the cutting fluid through the hole in the scraper, and thus the machining process is affected.. Chip solution for small particles of chips, there are mainly two kinds of magic separation and filtration. The purpose of this paper is based on several rows of chip structure analysis, pares their respective advantages and disadvantages, and the bination, improve the application in machining center thoroughly swarf filtration can be achieved. In this process, familiar with the structure of the general mechanical structure design process, and through the form of threedimensional and twodimensional map. My main design content for the entire mechanical system, the structure, the transmission design, selection including motor, reducer selection, V belt transmission design, scraper chain transmission design, magic row chip structure design, filter paper scraps discharge structure design and row chip appearance, water tank node structure design. Design thinking is starting from the row removal machine performance and the movement, and to the national quality and technical performance close to the design requirements of chip machine based, and hope to 蘇州科技學(xué)院本科生畢業(yè)設(shè)計(jì)（論文） IV design market demand for machining center posite chip removal device.
