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.
