产品概述：
金属结合剂基体型切割砂轮是指砂轮外圆环带为磨料工作层，中心部分为高强度高刚性的金属材质，也称作外环型切割砂轮。一般稍厚，刚性好，多用于中、大切深的切断或切槽。
Product overview
Metal bond high precision dicing blades with steel core is compound of steel plate and superabrasive work layer. The steel plate has high strength and high rigidity. They are generally used for deep cutting and grooving.
规格型号：
规格型号主要分为1A1/3、1A1R/4、1A1/5、1A1R/6。
1A1/3、1A1R/4 指基体型切割砂轮外圆无水槽；1A1/5、1A1R/6 指其外圆带水槽。
Specification

1A1/3 and 1A1R/4 are without water slot, while 1A1/5 and 1A1R/6 with water slot.
主要特点：
1A1 型金属结合剂切割砂轮：磨料工作层与基体厚度等高，精度高，多用于高精度切断或切槽，砂轮形状保持性好、使用寿命长。
1A1R 型金属结合剂切割砂轮：磨料工作层厚度大于基体厚度，便于排屑和冷却，多用于切深较大零件的切断或切槽，砂轮形状保持性好、使用寿命长。
Main features
The main features of 1A1 wheel: The abrasive layer height is same with the core; mainly used for high precision slotting and cutting off.
The main features of 1A1R cutting wheel: The abrasive layer is thicker than the core thickness, which makes easier for chip removal and cooling. It is mainly used for deep slotting and cutting off.
主要应用领域：
