I am in front of choosing the HSK A63 holder system for a new cnc milling machine. Do you have vibration damping comparisons between powgrip and hydraulic holders? What does it look like?
Below is a link to a study we did some time back between Hydraulic and PG. It goes in to more than just vibration damping; however, the general idea is that the TIR & damping characteristics of the systems are very similar. Where powRgrip benefits the most is in the rigidity of the toolholder, where hydraulic tends to struggle. bit.ly/3Q3zFlo If you have any questions on this let us know!
@@REGOFIXThank you for your answer :) Now I use GF milling machines - Mill S 400U and Mill S500. I use them for milling EDM electrodes and milling hardened steel - injection mold inserts. The spindles are weak but fast, the taper is HSK E40. Perfect for HSM. I use hydraulic, heat shrink and accurate ER chucks. In six months, the OPS Ingersoll Eagle V9 milling machine will arrive. The spindle will be HSK A63 taper and will be strong. After reading the file you sent, I am convinced that your system will be suitable for milling hardened steel and steel. I have another question about drilling. Do you think from an economic/technical point of view I should also use powRgrip (solid carbide drills from 2mm to 16mm, drilling in hardened steel)? Will I also gain a lot by investing in powRgrip compared to shrink or hydraulic chucks (longer drill life, better hole quality)?
The best way that we've come up with measuring holding force in a lab setting is through the twisting torque of a toolholder. We covered this in an older video from a few years back, one that should probably be updated in an early 2023 TechChat. The video can be found at this link: ua-cam.com/video/ixxTpRTkfjI/v-deo.html To be completely honest, every manufacturer of toolholders is going to says their is the best. We're no different, but we've tried our best to be fair and give evidence for why we feel this way. The PG system, through it's press-fit nature, has incredibly strong gripping force. Additionally, as David consistent mentions in our PG TechChat videos, we're also getting outstanding rigidity and vibration damping... all due to the press-fit design. I'll get with David and we'll put this all together in a TechChat for the coming weeks to spell things out a bit better through an updated demonstration.
Congrats David! Great video!

How's the holding force like compared to shrinkfit or hydraulic?

@@REGOFIX Thanks for answer, i'll take a look
