Diamond in Chinas national economy plays a very important role，and the diamond is also the important strategic materials of mechanical equipment. Especially in hard brittle materials, diamond cutting appear especially outstanding on Multi-line saws .The demand of silicon chips in integrated had become more and more, the Multi-line saws processing technology which is based on the grinding mechanism will be eliminated because its processing efficiency comparison is quite low, and cant cut hardness higher silicon carbide crystal, ceramic materials. This topic proposed the diamond Multi-line saws technology, using the technology of consolidation online saw silk grinding excision directly diamond grits, reduce the processing surface material damage, circular line continuous speed sawing silk one-way motion, greatly improving cutting efficiency and speed. It can be used for silicon crystal slice and high hardness material cutting processing,for its high precision, manufacturing cost cutting, low pollution to the environment, etc. This topic studied how the multi-line saws in multiple set, and tauted by tensioner institutions; How to adopt screw, nut institutions drive wire frame movement. And to understand the counterweight institutions; Do the basic design of the structure of a preliminary analysis.I Hope that throu
