Vitrified bond Diamond Grinding Wheels

Introduction of vitrified bond diamond grinding wheel

What is a vitrified diamond grinding wheel ?

Vitrified diamond grinding wheels combine the hardest known super abrasives held mechanically and chemically in glass (ceramic bond) to form some of the most highly efficient grinding products available on the market. Vitrified bond diamond grinding whee is a kind of circular bonded abrasive with through-hole in the center which made of diamond powder and vitrified (ceramic) bond. Diamond grinding wheel is composed of the diamond layer, transition layer and matrix.

More SuperHard can supply quality vitrified diamond grinding wheel with long life as well as fast cutting. We only choose the very strong synthetic diamond as the raw materials, we make sure not only the particle shape is round enough but also be with some sharp points, which can make sure we won’t lose the efficiency while we still want enough life from the wheels. So it will help you get fast, stable, much more PCD tools in unit time.

5. Vitrified diamond grinding wheel for thermal spraying industry.

Advantages of vitrified diamond wheels

– The porous structure of the abrasive improved diamond exposure and can prevent vertical streaks on workpiece and improve surface quality, obtain excellent surface finishes quickly and productively.

– Vitrified diamond grinding wheels the ability to withstand great forces of pressure without distortion, and to attain high stock removal rates. Accurately control geometric tolerances to make a good abrasive layer

– Good self-sharpening, high grinding efficiency,high wear resistance and less abrasive grain consumption

– High precision workpiece. pcd tools can reach high efficiency , good surface finish and edge no chipping

– Vitrified bond wheels offer tool life greater than 150 times that of resin bond wheel and can be easily trued and dressed on machine

– Superior edge quality, long life

– Increased production rates, delivery- 5 days lead time

Grain size selection of vitrified diamond grinding wheel

Grain Size	Machining Type	Application
W40(500# D35) W28(D20)	Rough	Regrinding a blade edge profile and sharpening of much worn inserts
W20 (800# -1000#, D20)	Universal	Standard grain size also can get a high sharpening efficiency, good quality surfaces
W10 (1500# D15A) W7 (2000# D15B)	Finish	Finishing grinding – getting a very good quality of machined surfaces
W5 (3000# D7) W3.5 (4000# D3)	Super Finish	Super finish grinding – getting a brilliant quality of machined surfaces
