Foreword

This standard replaces LY/T 1461-1999 "Technical Conditions for Refining Grinding Machines". The main differences between this standard and LY/T 1461-1999 are as follows. ---The hardness of the grinding teeth is greatly improved; --- Improve the geometric accuracy and shape position accuracy of the grinding disc; --- Balanced quality level has been improved, increasing the dynamic balance requirements of rotating grinding pieces. This standard is proposed and managed by the National Technical Committee for Wood-based Panel Machinery Standardization. This standard was drafted. Wood Industry Research Institute of China Academy of Forestry, Shanghai Huanghai Grinding Film Co., Ltd., Jilin Chengxin Industrial Co., Ltd. Limited liability company. The main drafters of this standard. Ouyang Lin, Zhu Weimin, Peng Zhicheng. The previous versions of the standards replaced by this standard are. ---ZBB97032-1988, LY/T 1461-1999.
