Foreword

This standard is identical with ISO 513.2004 "Classification and use of large groups and groups of application with a hard metal blade cut cutting material Code. " This standard is equivalent translation ISO 513.2004. For ease of use, this standard made the following editorial changes. --- Delete ISO introduction, increasing the foreword; --- "This International Standard" by "this standard"; This standard replaces GB/T 2075-1998 "cutting by chip form large groups and groups of application of hard cutting materials Code. " This standard and GB/T 2075-1998 compared to the following changes. Original code --- Big Three group to six kinds of different classification principles. The large group of the original standard, code-named P, M, K are three press cuttings In the form of classification; this standard large group codenamed P, M, K, N, S, H six types classified according to material to be processed. Identification colors P, M, K same as with the original standard, respectively, blue, yellow, red, newly added N, S, H, respectively green, brown, gray. --- Add some code group. --- This standard canceled the original standard group "Working and working conditions." --- Hard materials group increased the number of species. Carbide increased HF. mainly containing tungsten carbide (WC) uncoated carbide, Particle size < 1μm. Ceramic increased CR. Enhanced containing mainly alumina (Al2O3) ceramics. Diamond increased DM. monocrystalline Diamond. BN canceled a standard BN. polycrystalline boron nitride. Adds three. BL. containing a small amount of cubic boron nitride stand Square crystal boron nitride; BH. containing a large amount of cubic boron nitride CBN; BC. said boron nitride coating. --- Cancel the original standard Appendix A and B. The standard proposed by China Machinery Industry Federation. This standard tool by the National Standardization Technical Committee (SAC/TC91) centralized. This standard was drafted. Chengdu Tool Research Institute, Zhengzhou City, Diamond Precision Manufacturing Co., Ltd. The main drafters of this standard. check States soldiers, Xu Gang, Zhang Fengming. This standard replaces the standards previously issued as follows. --- GB 2075-87; GB/T 2075-1998. GB/T 2075-2007/ISO 513.2004

Introduction

Since different manufacturers use different methods for producing a hard cutting materials having different characteristics, so that the current in accordance with the characteristics of these hard Cutting material grades standardization is not feasible. Therefore, this standard is limited to hard-to-cut materials by use of classified and restricted to a large group from the group consisting of and use classification code The method (color marking and identification symbols). GB/T 2075-2007/ISO 513.2004 Cutting with a hard cutting materials classification and use Large groups and groups of application of the classification code

1 Scope

This standard specifies include cemented carbide, ceramics, diamond and boron nitride, including, for processing by cutting metal hard cutting materials Classification and use, and provides for their use. The standard for other purposes (such as mining and other impact tool, drawing die, metal plastic deformation tools, measuring comparator class) is Not applicable.

2 Code

Hard cutting materials use group code including letter symbols in Table 1 to Table 4 given, followed by - and uses large group specified in Chapter 3, "" And use group code. Table 1 Carbide Letter symbols material group HW mainly containing tungsten carbide (WC) uncoated carbide particle size ≥1μm HF mainly containing tungsten carbide (WC) uncoated carbide, particle size < 1μm HTa mainly containing titanium carbide (TiC) or titanium nitride (TiN) or both uncoated cemented carbide HC said carbide coating were a HT cemented carbide may also be referred to as "cermet." Ceramic Table 2 Letter symbols material group CA containing mainly alumina (Al2O3) ceramic CM mainly alumina (Al2O3) as the matrix, but containing non-oxide ceramic component is mixed CN mainly containing silicon nitride (Si3N4) nitride ceramics CR containing mainly alumina (Al2O3) reinforced ceramic CC aforementioned ceramic coating were Table 3 diamond Letter symbols material group DP polycrystalline diamond DM single crystal diamond Table 4 BN Letter symbols material group CBN BL containing a small amount of cubic boron nitride CBN BH containing a large amount of cubic boron nitride BC aforementioned boron nitride coating is carried out Example.
