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 tool s 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.
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&PCBN tool s,which are progressively wide spread in advanced manufacturing techniques in many branches of industry.
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 custo
mer’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 machini ng type, used grinder and properties of sharpened tool.
