A vitrified bond diamond wheel uses a glass-ceramic bond fired at high temperature. The bond has controlled porosity, which carries coolant into the cut and clears swarf, while its rigidity keeps the wheel profile accurate. Fengzuan vitrified bond wheels are used for PCD compact, carbide and ceramics with diamond, and for precision internal and cup grinding of hardened steel with vitrified CBN.





Production in our Shijiazhuang factory covers cold pressing on hydraulic presses, vitrified firing, precision turning, dynamic balancing and truing. We produce vitrified 1A1 parallel wheels in diameters such as 200, 300 and 350 mm, vitrified internal grinding wheels and cup wheels, all to your drawing.

Frequently Asked Questions
Why use a vitrified bond for PCD?
PCD is extremely hard. A vitrified bond stays rigid and porous, so it keeps cutting freely while holding the edge geometry needed for sharp, low-chipping PCD cutting edges.
Is vitrified available with CBN as well as diamond?
Yes. We make vitrified bond diamond wheels and vitrified CBN wheels, including vitrified internal grinding wheels and cup wheels.
How does vitrified compare with resin?
Resin cuts more softly with finer finishes; vitrified holds form better and is easier to dress, which suits precision profiles and PCD.
Which sizes are available?
Diameter Ø10–850 mm, grit 80#–3000#, concentration 50–150; thickness and bore to your drawing.
Can I order a sample first?
Yes. Samples are produced within 30 days; sample cost and freight are charged. MOQ for orders is 15 pcs.
