The making process of sintered dental diamond bit includes the steps of mixing metal and diamond powder, making slurry, painting diamond slurry, eliminating glue, sintering, etc. and diamond is sintered onto metal base body through sintering. The sintered dental diamond bit is fine, great in diamond particle holding force, high in grinding efficiency and long in service life. The improved production process has high production efficiency and low production cost. The diamond bit can be used mainly for dental grinding, carving and other grinding places. |
