  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
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.
