Steel and diamond

[Peter Fairbrother]

I have to grind some steel using a diamond tool. Any tips on extending
tool life?

Thanks,

Use a CBN tool instead?

If you are referring to diamond impregnated resin wheels, keep the pressure
very low to avoid tearing up the resin, and clean the steel powder off the
wheel frequently. I use meths for the latter.

No, it's metal bonded. I was more concerned about the diamond dissolving
in the steel. Presumably it should be kept cool, so a slowish speed and
coolant - suds or perhaps water.

I thought about using graphite as a lubricant - would that do anything?
Any other ideas?

The following is quoted from a email sent by Greg Brookes of Eternal Tools.
It refers to diamond drills, but I daresay the same priciples apply to your
tool.

"Remember that like all diamond drills pressure must remain light and have
plenty of water circulating in and around the work."

The main diamond attrition process is chemical and
temperature sensitive. It's no longer a problem at hand honing
surface speeds. Run the wheel at the lowest surface speed that
removes metal an acceptable rate.

Darex drill sharpeners use a single low speed diamond
wheel for sharpening both carbide and HSS drills.

1. First of all, you should ensure that the adhesive for diamond tools is good enough, because the steel being ground may also absorb diamond particles. Here I recommend the adhesive made of alloy powder: https://www.dymend.com/research-status-of-pre-alloyed-powders-for-diamond-tools;
2. There should be enough good cooling devices. Common water cooling may affect the steel material, which you need to pay attention to;
3. Select the appropriate diamond particle size. Select the appropriate particle size according to the grinding effect you want to achieve. Generally, the life of diamond tools with large particle size will be longer
