dc.description.abstractWe make use of zinc plate for lithography in order to print for nautical chart in Japanese Hydrographic Office. They are grained by some of abrasives, marbles and lubricants at the graining machine before plate-making. Our experiment researched to find out the schedules for better graining than graining which have done hitherto. The results were brought out as follows and they were good. 1) Case of graining on new plate Former graining schedule Times which is given abrasives 5 Kinds of abrasives Alundum (Aluminium oxide) # 120 Garnet # 80 Garnet #120 Amount of abrasives (kg) 3 Amount of lubricants (cc) ( 2 %K2Cr2O1 Aqueous) 1600 Time for graining (min.) 90 The cost of consumption for materials (yen) 302 Surface roughness Fig. 4 (a )~5 (f) Newly improved graining schedule Times which is given abrasives 2 Kinds of abrasives KA-Alundum # 320 KA-Alundum # 400 Amount of abrasives (kg) 0.6 Amount of lubricants (cc) ( 2 %K2Cr2O1 Aqueous) 600 Time for graining (min.) 20 The cost of consumption for materials (yen) 114 Surface roughness Fig. 10 (a)~(c) 2) Case of graining on reproducible plate Former graining schedule Times which is given abrasives 4 Alundum (Aluminium oxide)# 120 Kinds of abrasives Garnet # 80 Garnet # 120 Amount of abrasives (kg) 2.5 Amount of lubricants (cc) (2%K2Cr2O2Aqueou 1200 Time for graining (min.) 70 The cost of consumption for materials (yen) 217 Surface roughness Fig. 6 (g)~7 (I) Newly improved schedule Times which is given abrasives 2 Kinds of abrasives KA-Alundum # 320 KA-Alundum # 400 Amount of abrasives (kg) 0.6 Amount of lubricants (cc) (2%K2Cr2O2Aqueou 600 Time for graining (min.) 30 The cost of consumption for materials (yen) 114 Surface roughness Fig. 11 (d)~(f)en_US
