Sintering and brazing integrated diamond segment grinding wheel and preparation method

The invention provides a sintering and brazing integrated diamond segment grinding wheel and a preparation method. The preparation method comprises the steps of sintering preparation of grinding wheel segments and brazing connection of the grinding wheel segments and a grinding wheel base body. Diamond is adopted as abrasive particles, a metal binding agent is Ni-based alloy powder, in a vacuum environment, segments formed through pressing are pre-arranged on a grinding wheel base body and fixed to a welding clamp, and sintering of the diamond segment grinding wheel and connection of the grinding wheel segments and the grinding wheel base body are synchronously carried out. The method is suitable for the field of severe working conditions and ultra-precision grinding; raw materials and equipment are low in cost, the process period is short, and industrial production is facilitated; the service life is long, the wear resistance is good, and the comprehensive performance is strong. 本发明提供一种烧结钎焊一体化金刚石节块砂轮及制备方法，包括
