Manufacturing is the foundation and the pillar of the national economy. Thedevelopment of the manufacturing industry cannot leave advanced manufacturingequipment. Represented by honing machines, the equipment manufacturing industryhas very important influence for the development of national economy and theincrease of the national defense capabilities. Therefore, developing high-gradenumerical control honing machine which meet the national economy andmanufacturing technology has important strategic and realistic significance.Honing process is used for finish machining of hole. As the cutting tool onhoning machine, the structure and size of honing head have a great influence on theprecision of honing. Different processing object need different honing head whosestructure is different. The research of the design and manufacturing technology ofhigh precision and double feed honing head is an important way to improving thequality of honing process and competitiveness of machine product. It has an importanteffect to honing processing quality for honing head stiffness. Many factors on honinghead would affect stiffness such as different structure, different size, clearance,friction characteristics and so on.The finite element method is used in this paper. On the basis of theoreticalanalysis,3d modeling software Pro/E and finite element analysis software ANSYSWorkbench are used to establish the finite element model of high precision anddouble feed honing head. Static analysis and modal analysis are made for theassembly body of honing head after modeling. Analyzes the main weak links ofhoning head and puts forward Suggestions on how to optimize.A preliminary improvement is made for the unreasonable structure of the originalhoning head on the basis of the deep analysis. Meanwhile, select several importantsizes of honing head and make sensitivity analysis. The sizes of the big sensitivity areoptimized after sensitivity analysis.Finally, it is observed that deformation reduced significantly and stiffnessdramatically improved through contrasting the calculation before and afteroptimization. All of these explain that the optimal result is reasonable.
