    1.Application of vitrified diamond grinding wheel:

    they are widely used in the fields of tungsten carbide, ceramics, glsasses, PCD, PCBN, CVD, natural diamond, stones, etc. 

    2.Feature of vitrified diamond grinding wheel :

    1.High grinding efficiency than that of metal bonded diamond grinding wheel

    2.High abrasion resistance and less abrasive consumption 

    3.Small grinding force and low grinding temperature 

    4.High grinding precision of the workpiece,good surface quality and good maintenance of the shape of workpiece 

    More advantages of diamond grinding wheel:

    *high quality of PCD & PCBN insert edges after sharpening;
    *short grinding time&long tool life

    *high efficiency and accuracy of sharpening;
    *remarkable decreasing of unitary grinding costs;

    4. How to sharp the tools with PCD & PCBN inserts?

    Tools with PCD&PCBN inserts are very reten-tive, but demand an occasional sharpen-ing. In comparison with conventional tool mate-rials, the sharpening of PCD&PCBN tools requires another approach in scope of grindingmethods and grindingwheels char-acteristics. The sharpening of polycrystalline tools is a very challenging task both for users and for wheel manufacturers.

    To ensure the proper condition of PCD&PCBN sharpening process the following fac-torsare indispensable:
    high precision grinding machine with stiff construction and vibration dampening system which can guarantee high preci-sion grinding, demanded during sharp-ening of PCD & PCBN inserts; specially designed grinding wheels ap-propriate for high efficient and precision machining, which assures getting an ex-cellent blade edge quality.

    5. What kind of diamond grinding wheels to use?

    We have created a high effi-cient polycrystalline diamond wheels suit-able for sharpening tools with PCD&PCBN inserts.

    Thanks to modern technology, these grind-ing wheels have met the application in extremely accurate and efficient sharpen-ing processes of PCD&PCBNtools,which are progressively wide spread in advanced manufacturing techniques in many branches of industry.

    6.How to select a proper grinding wheel?

    In order to obtain high quality of PCD & PCBN insert edges after sharpening; we elaborate 5 grain size from rough grinding to super finish grinding for customer’s needs.

    As for other wheel parameters, such as grain concentration, wheel’s hardness and structure are chosen individually for each user in dependence on machining type, used grinder and properties of sharpened tool.

    Grain size selection of vitrified diamond grinding wheel:

    Grain Size

    Machining type

    Application

    D35

    D20

    Rough

    Regrinding a blade edge profiling and sharpening of much worn inserts.

    D15

    Universal

    Standard grain size-can also getting a high sharpening efficiency and good quality machined surfaces .

    D9

    Finish

    Finishing grinding – getting a very good quality of machined surfaces.

    D6

    Super finish

    Super finish grinding – getting a brilliant quality of machined surfaces.

    7. How to set the machining parameters?

    During PCD & PCBN inserts sharpening one should pay a particular attention to the proper selection ofmachiningparameters.
    Diamond grinding wheel, even made with the most advanced technology, never be efficient if its working conditions or machin-ing parameters will be improper.
