Description

Bernardo CBN Grinding Wheel for CM 14 – HSS Grinding

The CBN grinding wheel for the CM 14 sharpener is designed for precision grinding and resharpening of high-speed steel (HSS) tools and hardened steels. Cubic Boron Nitride (CBN) offers high hardness, thermal stability, and wear resistance, making it suitable for machining high-hardness ferrous materials. It ensures controlled stock removal, maintains cutting edge geometry, and profile stability even during intensive work cycles. It is particularly suitable for restoring cutting angles, concentricity, and microgeometry of the edge. Suitable for tool shops and mechanical workshops requiring dimensional precision, uniform surface finish, and long operational life.

Frequently Asked Questions

What is the difference between a CBN wheel and a diamond wheel (SDC)?

CBN (Cubic Boron Nitride) wheels are for high-speed steel (HSS) tools — they keep the cutting edge cool during sharpening without the risk of tempering. SDC (diamond) wheels are for tungsten carbide (HM/TCT) tools — diamond abrasive is the only one that effectively works carbide without wearing out the wheel. Using the wrong wheel results in poor sharpening and premature wheel wear.

Is this wheel compatible with my Bernardo sharpener?

Each Bernardo wheel is specific to the model indicated in the title. Always check the sharpener model before purchasing — the outer diameter, thickness, and bore hole dimensions must match exactly. For compatibility confirmation, contact Krollit. Customer support available in Italian.

How often should the grinding wheel be replaced?

A quality CBN or diamond wheel typically lasts 5–10 times longer than a traditional corundum wheel. Replacement is necessary when the wheel is worn to its minimum diameter or when it produces uneven sharpening despite the correct procedure. There are no fixed intervals — it depends on the intensity of use.
