Many people ask me what grinding wheel is suitable for M42 material of HRC 50-60. The answer is: Resin bond CBN grinding wheel, vitrified CBN grinding wheel or metal bond CBN grinding wheel can be used to grind M42 materials of HRC 50-60.
Hi-Bond CBN grinding wheel is recommended for grinding M42 material of hardness 50-60 HRC. The wheel has proven its best performance in grinding these materials in its class.
There are many types of Hi-Bond CBN grinding wheels, but we generally recommend that you choose the one with a 50 grit or higher fineness index (FI). This will make it easier to get a smooth finish on your workpiece.
If you are looking for a cost-effective, high performance materials grinding wheel for M42 material of HRC 50-60, then the electroplated cbn wheel is a good choice. The electroplated cbn wheel has proven its best performance in grinding these materials in its class.

But also depend on the wheel parameter and your machine condition.
If you want to grind M42 material with HRC 50-60 high hardness, the grinding wheel will be too expensive. It's very cost effective. But also depend on the wheel parameter and your machine condition. If you have a low hardness steel or not so hard material, it's better for you to use common grinding wheels like P80 or P100 which are widely used in metalworking industry nowadays because of good sharpness and wear resistance quality with reasonable price tag attached to it as well as its long service life, which means that it can work effectively under all conditions without any wear out problem so far!
Hi-BOND CBN grinding wheel is recommended for grinding M42 material of hardness 50-60 HRC. The wheel has proven its best performance in grinding these materials in its class.

Our quality control procedures ensure that you will receive only the best wheels available with consistent dia., concentricity and parallelism tolerances along with good surface finishes on all products we manufacture.
For grinding M42 materials with hardness 50-60 HRC, HI-BOND CBN grinding wheel is recommended. The wheel has proven its best performance in grinding these materials in its class.
The hardness of silicon carbide is 7.5-8.0 and the brittleness is high, so it will break your grinding wheel easily if you use black and green silicon carbide as abrasive.
Abrasives are divided into two types: one is mineral abrasives, such as corundum and diamond; the other one is synthetic abrasives, such as black silicon carbide and green silicon carbide.
You can choose resin bond CBN grinding wheel, vitrified CBN grinding wheel and metal bond CBN grinding wheel.
There are three types of CBN grinding wheel, which are resin bond CBN grinding wheel, vitrified CBN grinding wheel and metal bond CBN grinding wheel.
The main difference between them is how they are bonded to the substrates. Resin bond is weak in abrasive strength and not suitable for heavy-duty applications such as hard materials such as M42 material. Vitrified CBN grinding wheel has low abrasive strength but high hardness and wear resistance when used with M42 material because the bonding layer is made of pure fused alumina (Al2O3). Metal bond can be welded directly onto the base substrate with a thin layer of pure fused alumina (Al2O3) or diamond aggregates to achieve high hardness and wear resistance at high speed machining in low-temperature working environment (lubricated by oil or water).
