Foreword

GB/T 18376 "carbide grade" is divided into three parts. --- Part 1. grades of cemented carbide cutting tools; --- Part 2. geology, mining tools with carbide grade; --- Part 3. grades of cemented carbide wear parts. This section GB/T Part of 118,376. This Part replaces GB/T 18376.1-2001 "Grades of cemented carbide Part 1. grades of cemented carbide cutting tools." This section compared with the GB/T 18376.1-2001, the main changes are as follows. --- Carbide cutting tools to increase the classification of N, S, H three categories, and a corresponding increase in its main components, mechanical properties Basic requirements, recommended operating conditions, etc; --- Modify the rules of carbide cutting tools represented grades; --- Modify the mechanical properties of carbide cutting tools P, M, K and other groups of basic requirements; --- Improve the general level of carbide cutting microstructure structural requirements; --- Deletion of the test methods, inspection rules and test results to determine other content; --- Modify the operating conditions recommended cutting tool Carbide P, M, K and other groups. This part is proposed by the China Nonferrous Metals Industry Association. The non-ferrous metal part by the National Standardization Technical Committee. This section Zhuzhou Cemented Carbide Group Co., Ltd. is responsible for drafting. The main drafters of this section. Li Jing Rong, Yang Jianguo, Chen Ying. This part of the standard replaces the previous editions are. --- GB/T 18376.1-2001. Carbide grades Part 1. grades of cemented carbide cutting tools

1 Scope

This section provides cutting tools carbide grades and grades that classification rules and requirements for each category of recommendation and other operating conditions. This section applies to carbide cutting tools.

2 carbide cutting tools represented by the rules of classification and designation

2.1 Classification Grades of cemented carbide cutting tools by using different areas into P, M, K, N, S, H six, see Table 1. To meet the various categories Different requirements, according to the cutting tool and carbide materials with different wear resistance and toughness, divided into several groups, with 01, 10, 20 and other two-digit group number. If necessary, you can insert a number of supplementary group numbers between the two groups, represented by 05,15,25 and so on. Table 1 Category field use Processing P long chipping materials such as steel, cast steel, malleable cast iron and other long cutting processing Processing M Universal alloy for stainless steel, cast steel, manganese steel, malleable iron, steel, alloy cast iron, etc. Machining K short-chipping materials such as cast iron, chilled cast iron, short-chipping malleable iron, gray cast iron, etc. N non-ferrous metal processing, processing of non-metallic materials such as aluminum, magnesium, plastics, wood, etc. S heat-resistant super alloys and processing of materials, such as heat-resistant steel, processed nickel, cobalt, titanium alloy material of all kinds Machining H hard cutting materials, such as hardened steel, chilled cast iron and other materials 2.2 grades that rule Grades of cemented carbide cutting tools by the category code, packet number, segment number (when needed) composition, see Example 1. Example 1. Category Code By using segments of the packet number Segment No.
