GB/T 15306.1-2008 Indexable inserts for cutting tools - Ceramic inserts with rounded corners - Part 1: Dimensions of inserts without fixing hole(Class G) (English Version)
Indexable Inserts for Cutting Tools — Ceramic Inserts with Rounded Corners — Part 1: Dimensions of Inserts without Fixing Hole (Class G)
1 Scope
This part of GB/T 15306 specifies the dimensions of indexable ceramic inserts with rounded corners, without fixing hole, with 0° and 11° normal clearance, and with accuracy of Class G. These inserts are primarily intended to be mounted by top clamping on turning and boring tools.
This part is applicable to the indexable ceramic inserts with rounded corners, without fixing hole (Class G).
Ceramic cutting materials consist of a variety of oxides, nitrides, carbides and metals. Such ceramic materials are, for example, oxide ceramics (consisting primarily of aluminium oxide Al2O3), carboxide ceramics (consisting generally of a mixture of aluminium oxide and other materials such as titanium carbide TiC) and nitride ceramics (consisting generally of a mixture of silicon nitride and other materials, such as yttrium oxide Y2O3 and aluminium oxide).
