Metal adhesive and abrasive wheel made with same for cutting blue glass infrared cut-off filters

The invention belongs to a metal adhesive and an abrasive wheel made with the same for cutting blue glass infrared cut-off filters. All raw materials of the metal adhesive are superfine granularity powder, so that better gripping force is applied on a diamond, and the service life and cutting speed of the abrasive wheel can be increased. A certain quantity of boron carbide and titanium diboride are added into the adhesive, and the boron carbide and the titanium diboride do not participate in sintering and can timely fall off from the adhesive in the cutting process. The metal adhesive not only improves the keenness and stable cutting capability of the abrasive wheel and avoids knife trimming in the cutting process, but also, as the hardness of the two substances is high, plays a cutting assisting effect and improves the cutting capability of the diamond abrasive wheel. The abrasive wheel provided by the invention can meet the requirement of the blue glass infrared cut-off filters on cut crack openings. The cu
