The Research of Rigid Lapping Technique on Diamond Grating Ruling Tool
One of the effective method of improving diamond tool life on rulling large diffraction gratings is developing precise double-cone edged on line edge transfering tool.But traditional died weight or manual lapping technique couldn't meet the precision requirement of on line edge transfering tool.So preliminary studied rigid lapping of diamond grating ruling tool.Choosing traditional BC6063 shaping machine and made a series of alteration on it, achieved the automation of lapping process of diamond grating ruling tool. Through lapping grating ruling tool and AFM measurement find that the surface roughness of tool is 1.51nm,the radius of tool edge is 160nm, edge quality is good enough,this verified the feasibility of rigid lapping of diamond grating ruling tool and lay the foundation for developing precision lapping machine.
