生产线、材料、颜色代码先进的生产技术和特殊的配方可以生产出不同的档次产品，使得客户在任何特定应用领域里可以选择最合适的增强切片或磨片。	Production lines, material, color code Advanced manufacturing technology and special product formulas have permitted a high degree of product differentiation,enabling the user to select the most suitable reinforced cutting and grinding discs wheel for any specific application.

切片和磨片六种材料组成产品是基于其机械加工性能来进行分内的，产品商标代码系统对增强切片和磨片选择的最佳工艺进行简化。	Six material groups for reinforced cutting and grinding discs classification of material is based on their machining properties.The system of product label codes facilitates the choice of the optimum reinforced cutting and grinding discs.

Abrasive type code 磨料代码 A	Grit size 粒度 30	Hardness grade 硬度 Q	Bond 组合剂 BF
A=氧化硅 aluminum oxide C=碳化硅 silicon carbide Z=氧化锆磨料 zirconia alumina grain ZA=氧化锆/氧化铝磨料 zirconia alumina grain/Aluminum oxide AC=氧化铝/碳化硅 aluminum oxide/ silicon carbide WA=白刚玉 white corundum	16-24=粗粒度coarse 30-60=中等粒度m 70-220=中细粒度 fine-medium	硬度用字母（A-Z)从软到硬按升序排列 The hardness is graded from soft to hard by means of letters in alphabetically ascending order。 (A to Z) H-K=软 soft L-O=中等 medium P-S=硬 hard T-S=非常硬 very hard	BF=树脂结合剂 BF=Resinoid Bond 网片=增强，带无纺布或不带无纺布 Fibre=reinforced woven or ono-woven
