Shave tine knife is ground with correction top gem annulus with gear, in nickel of the plating on its - diamond cut has with electrochemistry law commonly. When making this kinds of tool, main problem is to should make sure tooth profile place wants geometrical form, because of by the ply of film inhomogenous, the dimension terribly of tooth profile of reason correction film is complex, and the requirement always can be not satisfied after amending. Chemically deposit nickel and diamond grain the method on embedded tool, without this defect. The advantage of this law is cut edge random complex model the face distributings absolutely and even, and film hardness relatively the film hardness of electrochemistry law rises significantly. The solution composition of chemical plating nickel is: L of ／ of vitriolic nickel 25g; L of ／ of 15g of acetic acid natrium; Glycol 15g ／ ; L of ／ of 20g of natrium of second phosphoric acid; Sulfur Niao 0. 0015g ／ L. Craft standard is: Solution temperature 2 ℃ of 92 ± , 5 ～ of PH ＝ 6. For better profit wet diamond grain makes his inside embedded cut (by amount and distributinging uniformity) , special appearance activator is added in solution a person operating from within in coordination with outside forces. 2 diamond grain is configured inside cut, its layer is thick 100 μ M is achieved inside 5 ～ 7h. The tool after plating should be in 350 ℃ maintain temperature 1h has heat treatment. The tool tooth profile that such acquisition is accorded with completely pair of direction and model the requirement of the face, and the surface is aleatoric paragraph of film that go up is microscopical hardness is 9000 ～ 10000MPa.
