DEVICE FOR HOLDING crystal diamond in position by toolmaking

摘要

The invention relates to devices for holding the diamond monocrystals in a predetermined position during sintering or brazing in a vacuum or protective atmosphere. The apparatus may be used in the manufacture of diamond tools oriented arrangement of the diamond crystal, for example, monocrystalline diamond drills, where the diameter of the diamond drill-holder body smaller than the diamond crystal. The device is made in the form of a cylindrical steel nozzle having, on the hollow side, on the longitudinal axis of the through hole in the shape of a truncated cone with a diameter of 0.2-0.5 mm, and the top nozzle on the sides two oblique planar slice, wherein the inner diameter of the cylindrical sleeve coupled to maximum diameter of non-working part of the tool body-holder providing the possibility to rotate and move glass, respectively, around and along the longitudinal axis of the holder of the diamond crystal. The device provides accurate setting of the orientation and retention of the diamond crystal with respect to the carrier body during sintering in a vacuum-brazing furnace, high productivity manufacturing diamond tools, and to reduce manufacturing costs.
