Electroplated diamond grinding wheel advantages:
① plating process is simple, less investment, ease of manufacture;
(2) without trimming, and easy to use;
③ monolayer structure determines it can achieve high operating speed, currently abroad, has been as high as 250 to 300m / s;
④ Although only a single layer of diamond, but there is still enough life;
⑤ For high accuracy, a high roller wheel, electroplating unique manufacturing method. Electroplated diamond grinding wheel due to these advantages, plating wheel high-speed, ultra-high-speed grinding occupy undisputed dominance. Electroplated diamond grinding wheel memory defects: coated metal substrate and abrasive combination of surface is not kept firmly chemical metallurgy combination abrasive actually only be mechanically entrapped mosaic coating metal, thus gripping force, diamond particles heavier load efficient grinding easy to fall off (or into the coating flaking), leading to an overall failure; coating thickness must be increased in order to increase the holding force, the results abrasive bare the height of chip space is reduced, the grinding wheel is prone to clogging, the cooling effect is poor, the workpiece surface is prone to burn. Domestic electroplated grinding wheel manufacturing is not yet optimized design cutting wheel topography, these inherent disadvantages of the single-layer electroplated diamond grinding wheel will be significantly limit its efficient grinding applications required by the processing conditions.

I believe this kind of material for grinding wheel in our life does not feel strange, then for this type of material, whether it has what particularly related commentary, resin grinding wheel is what kind of material? See the following description.
The resin wheel is a demand for larger tools. It is the use of terephthalic acid and a polyamide or other resin as a binder, the glue a tool by the diamond or cubic boron nitride millbase with an inorganic filler. This tool is being effectively used in a variety of grinding operation, such as surface grinding, cylindrical centerless grinding, grooving and inner circle grinding. For the resin wheel not only has the above characteristics, while the more important point is that the resin grinding wheel also has an organic binding agent, such a binding agent manufacturing a high strength of the cutting wheel, has a certain flexibility, low heat resistance, self-sharpening , making simple and short process cycle. The above is a brief introduction of lower resin grinding wheel process.
