Is the harder the grinding wheel the better?

We all know that wheels are softer and easier to dress, but shape profile retention is often suboptimal.
To improve the surface roughness of the workpiece, the hardness of the grinding wheel is too high, but it is easy to heat and vibrate, resulting in the problem of poor surface roughness.

So there are a couple of factors that we need to consider.

The Cutting Force of the Grinding Wheel Is the Key

For forming wheels to maintain force, it is intuitive that increasing the hardness of the wheel is the best solution. However, this is a problem that is prone to cutting force. If the cutting force of the grinding wheel is good, the grinding resistance will be small. In addition to the faster feed speed, the heat generation will be less, and the degree of rapid cooling and rapid heating of the grinding wheel will be small. . If only hardness is required, the grinding temperature may rise even higher, and the rate of grinding wheel consumption may even be accelerated.


Enhancement of binders

                                                      

The binder is the key to the self-sharpening effect of the grinding wheel, and it is also the main determinant of the hardness of the grinding wheel.
As far as forming grinding is concerned, in addition to balancing cutting force and shape retention, the requirements for binders will greatly improve grinding efficiency if heat dissipation and grinding ratio can be further improved.


                                                                      

In addition to the significant improvement in the grinding ratio, the reduced binder also frees up space for air holes, which increases the space for heat dissipation and reduces the chance of blockage.


Notice of Choosing the Hardness of Diamond Grinding Wheels

In the selection of forming grinding wheels, the most important thing is to avoid blind spots in pursuit of the hardness of the grinding wheels.
In fact, more attention should be paid to the basic performance of the grinding wheel such as cutting force, uniform structure and heat dissipation, so that the most suitable product can be selected.
