PROBLEM TO BE SOLVED: To improve a grinding efficiency by carrying out the grinding of plural kinds symultaneously whose condition is mutually different for the same processing surface of a work, in a method for grinding the work by a grind tape. SOLUTION: A grind tape includes two grind tapes T1 , T2 in which the roughness of a surface adhered by abrasive grains is mutually different. The work is rotated around its axis while push-pressing these two grind tapes respectively and symultaneously at the two appointed grinding positions facing to each other at intervals of the work on the processing surface 14 of the work 10. |
