Aimed at the engine support processing 4 meet the size requirements of the 17 and 6mm deep hole.</p><p>The design is divided into two parts overall design and the headstock design. Firstly, the overall structure of the machine tools design, need to determine the cutting parameters, calculation of cutting force, cutting torque, cutting power and tool life, and thus determine the main shaft, extended size, etc.Rendering the "three plans for a card", that is, process map parts to be processed, processing diagram, machine sizes contact General Plan, and the productivity calculation card. Secondly, the design of the spindle box, drawing the original design basis, for the identification of various common spindle box and the selection of components, to calculate the transmission gear ratios and the principal axis coordinates. Finally, the results of the analysis, the gear and shaft to check the strength and stiffness.</p><p>This special machine can meet the processing requirements to ensure the machining accuracy, tool smooth operation, reliable, simple, easy handling, easy maintenance and adjustment. Operation simple, reducing labor intensity and improve labor productivity.</p><p>Key words：special purpose machine; drilling; spindle box; transmission design</p><p>目 录</p><p>摘 要<span
