Summary: This standard specifies the tip rounded, without fixing hole, law backward angle of 0 ��, accuracy of U grade, indexable insert size ceramic cutting materials. These blades mainly from the top of the clamp on turning and boring tools Arbor. This section applies to a variety of ceramic cutting materials made ??of U- grade non-porous indexable inserts. Ceramic cutting materials from a variety of different oxides, nitrides and carbides and metal components. For example, such ceramic materials: ceramic oxide (composed mainly of alumina, Al2O3), oxide-carbide ceramics (mainly composed of other materials such as alumina and titanium carbide TiC), nitride ceramics (generally made ??of silicon nitride other materials such as Si3N4, and Y2O3, yttrium oxide and aluminum oxide).

Foreword

GB/T 15306 "Ceramic indexable insert" is divided into four parts. --- Part 1. nonporous blade size (class G); --- Part 2. perforated blade size; --- Part 3. nonporous blade size (U level); --- Part 4. Technical specifications. This section GB/T Part of 315,306. This part is GB/T 15306.3-1994 "ceramic indexable inserts without fixing hole size (U)" for amendments. This Part replaces GB/T 15306.3-1994. Section compared with the GB/T 15306.3-1994 The main changes are as follows. --- Canceled a standard 5.1 text. You can also choose K, P-type; --- Modify the cutting edge cross-sectional shape of the symbol S, K (formerly standard 5.2 Figure 1 cutting edge cross-sectional shape symbol S is amended as K, the symbol K Modify S); --- Increasing the cross-sectional shape of the cutting edge symbol K (the original standard 5.2 Figure 2); --- Modify the markup example (Chapter 9 of the original standard markup example in grades modify material code); --- Modify the name of measuring instruments Appendix A (Appendix A of the original block gauge modify the amount of blocks, dial gauge modify instruction sheet). Appendix A of this section is an informative annex. This part is proposed by China Machinery Industry Federation. This part of the tool by the National Standardization Technical Committee (SAC/TC91) centralized. This section is drafted. Chengdu Tool Institute. The main drafters of this section.

1 Scope

This section GB/T 15306 specifies the rounded tip, without fixing hole, law backward angle is 0 °, U-grade precision, ceramic cutting materials Into indexable insert size. These blades clamped on the main from the top and turning Boring Bars. This section applies to a variety of ceramic cutting materials made of non-porous grade U indexable insert. Ceramic cutting material consists of a variety of oxides, nitrides and carbides and metal components. For example, such ceramic materials are. Oxidation Ceramic material (composed mainly of aluminum oxide Al2O3) oxide - carbide ceramics (mainly composed of other materials such as alumina and titanium carbide TiC group A), nitride ceramics (typically made of silicon nitride Si3N4, and other materials such as aluminum oxide and yttrium oxide Y2O3).

3 blade type

Ceramic indexable inserts of the type specified in this standard are as follows. TN. Law backward blade angle of 0 ° of the equilateral triangle; SN. Act backward square blade angle of 0 °; EN. France back angle is 0 ° and 80 ° nose angle of the diamond blade; DN. France back angle is 0 ° and 75 ° nose angle of the diamond blade; HN. France back angle is 0 ° in the hexagonal blade; WN. Law and backward angle of 0 ° to 80 ° nose angle is not equilateral equiangular hexagon blade; FN. Law and backward angle of 0 ° to 82 ° nose angle is not equilateral equiangular hexagon blade; RN. circular blade method backward angle of 0 °. This Part of the blade has two kinds of chip breaker grooves with and without chip breaker. Usually you should use ceramic inserts with a chamfer or rounding the cutting edge of the cutting edge, see Chapter 5.
