A chip breaker of super hard bit and its attaching method

摘要

More particularly, the present invention relates to a chip breaker and a method of attaching the chip breaker to a tip of a chip breaker installed in a tip of a tool of monocrystalline diamond, polycrystalline diamond (PCD), polycrystalline CBN (PCBN) And a method of easily attaching the chip to a chip breaker of a high-pressure sintered bite and a method of attaching the same, which is characterized in that the chip is easily processed and its installation process is simple and a high-performance bite can be supplied at low cost .;In order to achieve the above object, the present invention relates to a method for attaching a hemispheric chip breaker (10) to a top surface of a tip (20) of PCD, PCBN, CVD and a single crystal diamond bite (B) The chip breaker may be a polyhedron or a polyhedron. The material of the chip breaker may be a high-speed steel, a ceramic material, or the like. (Ag) in an amount of 60 to 65 parts by weight, copper (Cu) in an amount of 32 to 38 parts by weight The activity of 1.5 to 2 parts by weight of titanium (Ti) was found to be about 10^-5Torr Vacuum is applied to the inside of the vacuum vessel by applying heat of 700-850C.
