In precision grinding, especially of hard materials such as carbides, the choice of abrasive wheel is very important in determining the best efficiency, finish and the cost-effectiveness of the process. Diamond and CBN (Cubic Boron Nitride) wheels are two of the giants in this industry. When the toolmakers and manufacturers are trying to reach maximum performance, they need to realize the advantages and the most suitable uses of each. Zhengzhou Ruizuan Diamond Tool Co., Ltd. is the leader in the development of high-performance grinding solutions which provides specialized wheels to each challenging material.
Being aware of the Core Differences.
Diamond and CBN wheels are essentially different in composition and material affinity even though they are recognized as the super-abrasives. Diamond wheels also have synthetic diamond grains as the cutting tool. Diamond is the hardest material known, and thus it is very good in grinding non-ferrous materials. Conversely, CBN wheels are made using Cubic Boron Nitride that is the hardest when compared to diamond. The difference is in the fact that they are chemically compatible. When milling ferrous materials, CBN will be thermally and chemically more stable. This is the basic difference that determines their performance and gives them respective niches in cutting of carbides and other hard materials.
Superiority of Diamond Wheels in Carbide Uses.
Diamond wheels undoubtedly reign supreme when the material used is carbide. Tungsten carbide and cobalt binder Carbides are infamously hard and abrasive. Diamond grains are extremely hard, meaning that they slice through the carbide matrix efficiently and cleanly. On carbide, a diamond wheel causes much less wear on the wheel than using conventional abrasives and this means that the wheel life is much longer and the grinding performance is more predictable as time progresses. The efficiency also minimizes the heat produced during the grinding process which is very essential in avoiding micro-cracks and thermal damages on the expensive workpiece made of carbide. The diamond wheel provides unmatched surface integrity and precision in tasks such as sharpening carbide tipped tools, grinding carbide inserts or finishing complex carbide parts. To achieve this performance, Zhengzhou Ruizuan Diamond Tool Co., Ltd. designs its diamond wheels with a special bond system to be able to cut faster and provide an excellent finish with all carbide materials.
The CBN Wheels Special Niche.
In another, though not less significant, area, CBN wheels perform better. Their main advantage is hard and tough ferrous materials grinding. A CBN wheel will do a better job than diamond, in the event that you are working with hardened tool steels, high-speed steel (HSS), or other alloys made of iron. The reason is that in the high temperature produced during the grinding process, carbon in a diamond wheel may be chemically reactive with iron and hence a quick wear in the wheel. CBN is chemically neutral to iron and therefore does not go out of shape, thus staying sharp and cutting well longer. Thus, a CBN wheel is not preferable in pure carbide, but this type of solution is the most effective in steel-based components or any task when a carbide tool is brazed onto a steel shank and it is necessary to grind both materials.
The Question of Deciding What To Do with Your Operation.
Whether to use a diamond or a CBN wheel would depend on the kind of material you are grinding. When it comes to the operations that are specialized in machining and tooling of carbide, the most effective and cost-effective way to go is to invest in the production of diamond wheels of the finest quality. It guarantees the highest material removal rates, high workpiece quality as well as optimum wheel life. In stores that use hardened steels most of the time CBN wheels provide significant productivity improvements. Considering such complex situations with composite materials, it is recommended to consult their expert. Not only the tools but technical knowledge is also available to Zhengzhou Ruizuan Diamond Tool Co., Ltd. to assist you to select the best abrasive solution so that your grinding operations will be as productive and the cost-effective as possible. The right choice is as efficient as possible in the graining process, as well as it safeguards your precious pieces of work.
