Vitrified Bond Grinding Wheels for PCD and PcBN

PCD is hard - very hard. If you want to grind PCD tools then you need high-quality vitrified bond wheels from Moresuperhard CO. Ltd - the cooperation company of Coborn Engineering.

If a diamond wheel is to grind PCD it must be kept ‘open’ by frequent dressing. This exposes new sharp diamond and keeps the wheel cutting freely. A dull wheel can soon start to vibrate or ‘chatter’ especially if the machine is not rigid. Wheel, machine and PCD all interact. Soft wheels will grind easily but then the life will be low. A hard wheel may not suit your machine. A few experiments are needed.

Moresuperhard Ltd offers 5 vitrified bond formulations with varying degrees of hardness and diamond concentration. All wheels are dynamically balanced. The standard wheels are held ex-stock in theUK, ready for immediate shipment.
