While diamond has always been thought of the hardest material known to man. However, modern science has created an even harder material when exposed to high temperatures, it is known as CBN. CBN is named after its cubic form of boron nitride is enhancing the grinding wheel experience. CBN also has a higher superior thermal stability and chemical makeup than that of diamond, making it the ideal tool for the ferrous grinding industry.

 

The thermal stability of CBN is another significant feature over diamond is another big advantage that is held. Since diamond is pure carbon that is formed under pressure, it is not ideal for grinding steel. The high thermal temperatures that are caused while grinding cause the steel to take in the carbon atoms from the diamond wheel and result in eroding the diamond grit. CBN isn’t made up of carbon, just boron and nitride making it the ideal super abrasive for grinding steel, stellate and nickel-based alloys. Our wheels can be utilized in all three areas of centerless grinding:

Through Feed: In through feed grinding the workpiece enters one side and exits the opposite side. The regulating wheel in through-feed grinding is moved away from the plane of the grinding wheel in such a way that puts a lateral force component, feeding the workpiece through between the two wheels. Through feed grinding can be an efficient centerless grinding technique, because it does not require a separate feed mechanism; however, it can only be used with cylindrical workpieces.

 

Another technique that can be used with centerless grinding wheels is end-feed grinding. In end-feed, the workpiece is fed in on one side and comes to rest against an end stop. At this point, the grinding operation is performed, and then the workpiece is fed in the opposite direction to exit the machine. Tapered workpieces are the best for end-feed grinding.

 

The third technique that can be utilized, is in-feed centerless grinding. In-feed grinding works well with complex shapes. Before the grinding process can begin, the workpiece is manually loaded into the machine and the regulating wheel is moved into place.
