BS 4193-19:1993 镶硬质合金刀具.无固定孔的圆角的可转位陶瓷镶装刀片的尺寸规范

This part of ISO 9361 specifies the dimensions of indexable ceramic inserts with rounded corners, without fixing hole, and with 0°and 11°normal clearance. These inserts are primarily intended to be mounted by top clamping on turning and boring tools. Ceramic cutting materials consist of a variety of ox-ides, nitrides and carbides. In contrast with hardmetals (including cermets) ceramics do not have a metallic binding matrix. Such ceramic ma-terials are, for example, oxide ceramics (consisting primarily of aluminium oxide AI2O3), carboxide cer-amics (consisting generally of a mixture of alu-minium oxide and other materials such as titanium carbide TiC) and nitride ceramics (consisting gen-erally of a mixture of silicon nitride and other ma-terials, such as yttrium oxide Y2O3 and aluminium oxide).

BS 4193-20:1993 镶硬质合金刀具.第20部分:有固定孔圆角可转位陶瓷刀片尺寸规范

This part of ISO 9361 specifies the dimensions of indexable ceramic inserts with rounded corners, with cylindrical fixing hole, with 0°normal clearance. These inserts are primarily intended to be mounted by top and hole, or hole alone, clamping on turning and boring tools. Ceramic cutting materials consist of a variety of ox-ides, nitrides and carbides. In contrast with hardmetals (including cermets) ceramics do not have a metallic binding matrix. Such ceramic ma-terials are, for example, oxide ceramics (consisting primarily of aluminium oxide Al2O3), carboxide cer-amics (consisting generally of a mixture of alu-minium oxide and other materials such as titanium carbide TiC) and nitride ceramics (consisting gen-erally of a mixture of silicon nitride and other ma-terials, such as yttrium oxide Y2O3 and aluminium oxide).
