Hardened finishing technology has made ​​great progress, and the emergence of some new processing methods

In order to improve the carrying capacity of the gear at home and abroad since the 1970s has been widely adopted hardened technologies. Over the years, hardened finishing technology has made ​​great progress, and the emergence of some new processing methods. We combine shaving honing method and the method has the advantage, developed a new structure of the coating with CBN honing wheel, and a plating method to improve the diffusion honing wheel CBN materials and the bonding strength between the substrate. The structural design of the honing wheel structure honing wheel, there are two, namely the overall style and assembled (see Figure 1).  abrasive grinding  in the overall through-slot basis, the development of CBN honing wheel  abrasive wheels  by the gear-shaped cutter body 1, the gear-shaped plate 3, the gear plate 2 is composed of honing shape, positioned by the positioning pin 4, using six bolts 5 fixed. 1,3 on the tooth surface with a certain  Diamond blade , width 4mm, serves as a guide only. The honing width of 10 ~ 11mm in round honing surface of the tooth plate 3 is plated with CBN abrasive, the use for honing. Meanwhile, in order to facilitate and reduce the chip honing pressure, the honing on the board with two flute, thereby forming three honing surface and the respective side edges. In honing, in addition to the tooth surface of the honing tool effects, both sides of the blade will have a shaving function, honing plate 2 are interchangeable.
