金刚石磨具的指标包括金钢金刚石种类(磨料)、粒度、硬度、结合剂、浓度及工具的形状和尺寸。金刚石磨具的标志方法举例如下: JR 120 Y1 S75 BW 150×35×32×10×3 磨料粒度硬度结合剂浓度形状尺寸(外径×厚度×孔径)(工作宽度—厚度) 1.磨料指金刚石的种类,有天然金刚石和人造金刚石两大类,分别以JT和JR表示。金刚石比重为3.5,一般称量单位为克拉(1克拉等于0.2克)。 2.粒度为金刚石磨料颗粒尺寸大小的标志。粒度号80,即磨料颗粒尺寸为200～160微
Indicators for diamond abrasives include diamond type (abrasive), grain size, hardness, bond, concentration and tool shape and size. An example of a diamond abrasive marking method is as follows: JR 120 Y1 S75 BW 150 × 35 × 32 × 10 × 3 Abrasive Particle Hardness Binder Concentration Shape Size (OD × Thickness × Aperture) (Working Width - Thickness) 1. Abrasive refers to diamond The types of natural diamond and synthetic diamond two categories, respectively, JT and JR said. The diamond has a specific gravity of 3.5 and a typical unit of measure is carat (1 carat equals 0.2 g). 2. Particle size diamond abrasive particle size of the logo. Particle size 80, ie abrasive particle size 200 ~ 160 micro
