Synthetic superhard cutting tool materials

 Synthetic superhard cutting tool materials, manufacturing many ways, here introduces hot vapor deposition method and the.
Hot pressing manufacturing of diamond and cubic boron nitride devices are used in the top or sides of the top six  abrasive paper sheet sides of the hydraulic machine. Suppression of monocrystalline superhard materials. Pyrophyllite raw materials need to be placed in the cavity. Pressing the raw material powder PCD monocrystalline graphite sheet, graphite sheet and Ni-Mn activator sheet laminate is placed in the cavity; suppress PCD PCD poly crystal wafers is the raw material powder, adding binder Ni, Si, Co, etc.; suppression CBN crystal powder raw materials for the hexagonal boron nitride (HBN) powder; suppress poly chips PCBN CBN crystal powder raw materials, but people need to be set separately catalytic agent and binding agent. Hot-pressing process is shown in Figure 1, Figure 2. The pressure, temperature and pressing flap wheel  time are listed in the figure.
Pressurizing the boost pressure during, the final pressure is different, pyrophyllite pressure in the cavity of the top portion of the pressure is not the same weight, in Figure 1, Figure 2 shows a top hammer unit pressure is the pressure . Temperature chamber temperature. Time is the heating time, holding time and cooling time sum of the process, for a variety of presses, these parameters will be different
