    摘要： The present invention provides a method for extending diamond tool life in diamond machining of materials that chemically react with the diamond tool in which the surface electric potential of the workpiece is adjusted or tuned to be adequate to inhibit the chemical reaction between the diamond tool and the workpiece during the diamond machining operation. As the chemical reaction is inhibited, the chemical wear rate of the diamond tool is reduced and diamond tool life is extended. The surface electric potential of the workpiece can be adjusted by electrically charging the workpiece. In one embodiment, conduction charging is used to adjust the surface electric potential of the workpiece to inhibit the chemical reaction between the diamond tool and the workpiece. In another embodiment, induction charging is used to adjust the surface electric potential of the workpiece to inhibit the chemical reaction between the diamond tool and the workpiece.

    摘要： A cermet tool includes from 75-95 volume % of a hard phase and from 5-25 volume % of a binder phase. The hard phase has a first hard phase with a core portion of (Ti, Nb, Mo) (C, N) and a peripheral portion of (Ti, Nb, Mo, W) (C, N) or (Ti, Nb, Mo, W, Zr) (C, N), a second hard phase with both a core portion and a peripheral portion of (Ti, Nb, Mo, W) (C, N) or (Ti, Nb, Mo, W, Zr) (C, N), and a third hard phase of (Ti, Nb, Mo) (C, N). The ratio of Nbs/Nbi is from 0.8 to 1.2, where Nbs is a maximum Nb amount in a surface region and Nbi is an internal Nb amount in an internal region. The ratio of Ws/Wi is from 1.0 to 1.5, where Ws is a maximum W amount in the surface region and Wi is an internal W amount in the internal region. The area ratios A1, A2, and A3 of the respective hard phases are from 75 to 95 area % for A1, from 4 to 24 area % for A2, and from 1 to 24 area % for A3.

    摘要： A method for preventing the wear of monocrystalline diamond tools by applying multiple physical fields during ultra-precision machining is disclosed, wherein dislocation form of lower energy state will appear by applying different physical fields such as electric field, magnetic field and laser irradiation around the diamond tool so as to change the construction of crystal interface and interfacial energy. Consequently, solid transformation will appear in the materials during the cutting process of nano-scale precision so as to change the cutting characteristic of the materials and prevent the wear of monocrystalline diamond tools during ultra-precision machining The method can be mainly used for ultra-precision machining
