Treatment for Cutting Tool Shanks

08/28/2018 3:33 PM

Does anyone know a company that sells a system to apply a chemical treatment to the shank of a cutting tool to eliminate or minimize tool pull-out?

Sorry, but I didn't find anything about a shank treatment in your link. Harvey might certainly be using such a process, but back to my question. Are you aware of a company that sells such a system?

Thanks. I'm familiar with this Safe-Lock, but that requires safe-Lock holders. We're using shrink fit

Nice fancy patented name but it looks like a light sand blasted profile to me. A light blasting on a polished shank would certainly increase the friction.

Thanks. That looks like what we're after. But our tech guys think it's more of a coating than a sandblast. What do you think?

Could be a zinc phosphate coating.

Could be ESD....

..."Carbinite is a tungsten-carbide alloy that can be applied to most metals using a process called electrospark deposition (ESD), yielding a true metallurgical bond. This high bond strength far surpasses any spray-on coating currently available. Carbinite can be used as an alternative to spray, thermal, or diamond coatings in many applications.

Thanks SolarEagle!

This could be a good option. I'm sending for samples.

The problem is that you have a hardened, polished jaw (or collet) gripping a hardened, polished shank. Not much friction there.

I don't know if knurling a shank and sand blasting a collet, or sand blasting both, would help, but it might be worth a try.

Thanks. For now, we're sandblasting, while we look for a better technology. But thanks again for your response

Thanks

But we're using carbide plain shank tools and Rego's method would require flats. Good option otherwise.

Thanks again

Put a little lapping compound on the shank. The grit will increase the friction and it can easily be cleaned off.

Thanks. But we're looking for more of a mass production process
