GB/T 15306.3-1994 Indexable inserts for cutting tools--Ceramic inserts with rounded corners--Dimensions of inserts without fixing hole(Class U) (English Version)
This standard specifies the dimensions of indexable inserts made of ceramic cutting materials with rounded tip, no fixed hole, 0° normal buckle angle, U-level precision. These inserts are primarily clamped on turning and boring tool holders from the top. This standard applies to U-class non-hole indexable inserts made of various ceramic cutting materials. Ceramic cutting materials are composed of various oxides, nitrides, carbides and metals. For example, these ceramic materials are: oxide ceramics (mainly composed of alumina Al2O3), oxide-carbide ceramics (mainly composed of oxide and other materials such as titanium carbide TiC), Nitride ceramics (generally composed of silicon nitride Si3N4 and other materials such as yttrium oxide Y2O2 and alumina).
