The development of technology, high strength, high wear resistance, high hardness, high temperature, light the continual emergence of new materials, but also to the high quality machining, high precision, high efficiency, automatic direction continues to develop, resin bond diamond wheel performance, structure, process parameters and preparing wheel grinding method, process parameters, etc. for further research needed to meet the requirements of the domestic market.
Superhard abrasive means: with artificial diamond or cubic boron nitride abrasive made ​​of superhard abrasive. It has the following characteristics and marking: Concentration, binders, particle size, diameter, shape code markings are in accordance with the above characteristics Abrasives 1998 National Standardization Technical Committee prepared by the State Publishing House of China National Machinery Industry Standardization provisions for each standard. Concentration means: refers to the hard mold per cubic centimeter volume contained within the superabrasive grams, with 100% means that (generally the higher the concentration, the higher the price of diamond grinding wheel ). Binders means: binding agent used superhard abrasive category. Bond Code is as follows: resin bond B metal bonded M vitrified V.
Superhard diamond wheel grinding tool types that belong to the past or the present or in the future have achieved good economic effects.

Laser cutting machine laser beam focused into a small spot with a minimum diameter , the focal point to achieve high power density. Then heat is far more than the input beam reflective material , or a conductive diffusion part , the  dc wheel material is heated to vaporization temperature rapidly evaporated to form holes . As the beam moves linearly relative to the material , so that holes are formed continuously through a narrow slit . Trimming hot little effect , basically no deformation of the workpiece .
Metal laser cutting machine process also add and cut material with suitable auxiliary gas . When starting a steel cutting oxygen as an auxiliary gas and molten metal to produce an exothermic chemical reaction of oxidation of the material , while helping blown away by cutting slits in the slag . Polypropylene plastic cutting a class using compressed air , flammable materials such as paper cutting use of inert gases. Cotton , but also the auxiliary gas into the cooling nozzle of the focus lens , the lens holder to prevent dust contamination of the lens into the lens and cause overheating . Most organic and inorganic substances can be cut with a laser . The thickness of the component in possession of heavy industrial manufacturing metal processing industry, many metal materials, no matter what kind of hardness , can be cut into shape without deformation ( currently the most advanced metal laser cutting machine can cut steel industry can already close to 20mm).
