Knowing The Underlying Difference Diamond And CBN
To know which wheel will last; we have to start by knowing the construction make and properties of both types. Diamond wheels contain synthetic diamond crystals, which are the hardest known material on earth. This provides them with unprecedented material removal rates in the hardest and most abrasive of materials. CBN wheels: CBN stands for Cubic Boron Nitride, the second hardest material when diamond isn’t available. CBN is also somewhat less hard, but it has outstanding thermal stability and a contrasting chemical affinity.
The long wheel life is the result of selecting the wheel that works best for the specific workpiece material. Very efficient on non-ferrous materials. Diamond grinding wheels are suitable for machining and are almost resistant to wear, but are only suitable for grinding wheels of a certain diameter. This can include hard ceramics, advanced composite materials, glass, granite and tungsten carbide. When grinding such materials, a diamond wheel keeps its cutting edges longer, thoroughly outclass any conventional abrasive. Such materials would be rapidly abraded away by a CBN wheel, the life of the wheel being proportionally shortened.
On the other hand, CBN wheels are made for grinding ferrous materials. Such materials might encompass hardened tools and die steels, high speed steels and other iron based alloys. The chemical reaction between diamond (carbon) and ferrous metals under high grinding temperatures leads to something called “graphitization,” in which the diamond tip wears away rapidly. CBN is chemically inactive to iron, it does not react the same way. When you grind, the hard Tough steels, a CBN will keep it sharp and hold its form for an extremely long time compared to a diamond that would be used up in no time.
Application Scenarios and Durability in The Heavy-duty Environment
The operation of heavy-duty grinding is highly complex and produces tremendous heat and pressure. If your business specializes in carbide, ceramics or stone, your best bet when seeking out a high-quality diamond wheel is to look to Zhengzhou Ruizuan Diamond Tool Co., Ltd. It will cut evenly, which means less wheel changes, less down time and a cost per part that is the same today as it will be throughout the life of the wheel. The wheel life is increased due to the fact that the diamond abrasive is cutting materials for which it is chemically and physically adapted.
Opportunity winner for operations in hardened steels and other ferrous is by far the CBN wheel. In demanding processes such as grinding of crankshafts, gear tools or knife blades, the thermal stability of CBN is a distinct edge. It can be ground at high temperature without hardness loss as well as resistance to chemical attack. The result is a wheel that has a very long life, does not change its shape (because the grinding dust falls inside the ring), and achieves high finishes over long lengths of time. This outstanding wear resistance results in a longer life span and significant cost savings in the context of particular applications.
The Economically Responsible Choice for Your Business
So, which wheel is more durable? As with many thorny questions in cycling, the question cannot be answered abstractly. The extension of the lives of Diamond wheels and CBN wheels can be achieved by the use on their optimum workpiece groups. Using the wrong abrasive for your material will results in premature wear, poor performance and costly operation.
At Zhengzhou Ruizuan Diamond Tool Co., Ltd., we want to remind you that the most long-lasting wheel is one which is properly manufactured for its application. Diamond provides the best long life solution for non ferrous, hard and abrasive materials. CBN is geared to cold and tough ferrous material, if you want extended life. Thanks to the guidance of our technical specialists, and just by knowing your main workpiece materials, you also invest in wheel technology that will have a long life and good return on investment for all your heavy-duty grinding.
