Abstract Modular machine is based on general components, according to the specific shape of the workpiece and process design of special components and fixtures, consisting of semi-automatic or automatic special machine tools。 The design includes two aspects: First, the overall design of modular machine, based on the analysis of machining parts, according to the processing requirements, select the positioning reference, determine the form and structure of the machine, select the tool you want, determine the cutting parameters, choose appropriate components for general using, and then drawing " three-diagram and one-card ", including the machining parts process diagram, schematic diagram, machine contact dimension drawings and productivity calculation card ;second is the design of Left-side Spindle Box, including the original basis Figure drawing, the spindle selection, design and calculation of the transmission system, drawing coordinate inspection chart, select the attachments of the box, drawing multi-axle box assembly general diagram and the supplementary of parts processing diagram。

The design take full use of general components and shorten the design cycle of the machine , Productivity and machining quality are guaranteed, and at the same time reduces the labor intensity, improve the benefit of enterprise, and it has good adaptability and economy。

Key words: drilling; Modular Machine; three-diagram and one-card; Left-side Spindle Box
