Abstract

Abstract: It is an effective way to solve the problem of tool life and realize on-line edge turning technique by using arc-edge grating ruling tool in grating ruling process. Arc-edge ruling tool has a high demand for the accuracy and quality of tool edge. It is difficult to make the arc-edge grating ruling tool with on-line edge turning function, and there is barely arc-edge tool lapping machine for grating ruling at home and abroad. So above-mentioned machine needs to be developed urgently. Based on the development of lapping technique and lapping machine for arc-edge grating ruling tool, a new type of arc-edge tool lapping machine for grating ruling based on leverage load mode is designed. According to traditional machine design procedure, function analysis, overall design, and detailed structural design of the machine are studied; the vibration of micro feed system and load system is analyzed, and the resonance possibility of the machine during lapping tool process is excluded. Finally, the assembling and adjusting of the machine is finished, and an arc-edge tool is produced with designed orientation angles ∠D(63 °), nose angle ∠J(90 °) and arc-edge radius R(8.56 mm). Observed by an microscope with 460-time magnification, arc edge of the above ruling tool is clearly visible, fine and clean, no chipping defects etc.. The results illustrate that the arc-edge tool lapping machine designed by this method can be used to lap arc-edge grating ruling tool. It also demonstrates that the above analysis and design method is meaningful to the design of arc-edge tool lapping machine and other machines.

Key words: arc-edge, grating ruling tool, leverage mode, tool lapping machine
