Foreword

This standard replaces GB/T 14319 "super oil stone" and GB/T 14320 "vitrified honing stone", the main substance of the amendment as follows:

--- Modify the Whetstone whetstone;

--- Increasing the foreword;

--- Modify the normative references;

--- Modify the grindstone shape code, abrasive particle size markers;

--- Modified tag example grindstone;

--- Deleted kgf Rockwell hardness value of working conditions in the steel ball load will 300.25N corrected to 306N;

--- Redefined grindstone inspection rules (Chapter 6 of this standard). The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee Abrasives (SAC/TC139) centralized. This standard was drafted. Zhengzhou Institute of abrasive grinding abrasive Abrasives Co., Ltd. and pigeons. The main drafters of this standard. Li Ning, Ma Jianyong, Chang Wu. This standard replaces the standards previously issued as follows:

--- GB/T 14319-1993, GB/T 14320-1993. Vitrified bonded abrasive grindstone and honing Ultra-fine grinding millstone

1 Scope

GB/T 14319-2008 is the Chinese national standard on bonded abrasive products - vitrified stones for force-honing and superfinishing, in the field of manufacturing engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 3 June 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2009. Classification: ICS 25.100.70, CCS J43. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the ultra-fine grinding grindstone and vitrified honing grindstone product classifications, technical requirements, test methods, inspection rules And signs, packaging, transportation and storage. This standard applies to a particle size of F320 ~ F1200 various common abrasives vitrified superfinishing grindstone; This standard applies to the honing process can be strong in the grinding load 7.84MPa ~ 39.2MPa ordinary abrasive vitrified Honing grindstone.
