Movement is handle by lathe external handles to the lathe internal implementation artificial control for machine tools. In the design, the main task is according to the parts during the design and calculation, including processing machine tools, spindle speed, the three elements of cutting the reasonable selection of the processing technology, as well as the typical fixture design. This article involves two parts, the first part is the analysis of the handle seat parts and processing procedures. Two drilling in the second part is for parts with different way of positioning, clamping typical fixture design. Through the design on the one hand, make us more familiar with the whole process of the product processing design, at the time of processing plan formulation, give full consideration to its economical efficiency and feasibility. On the other hand through the handle parts of the machining process planning design and drilling fixture design, trying to find out a simple and practical processing methods, to provide the reference for the manufacture of similar parts. Key words: the handle
