Why do ya say that Ed with Carbide indexable tooling I dont see why you cant take of .030-.050 slow and steady of course with proper Rpms... JMHO I think its Material on this one . The Pm 25mv I had chattered with a ½ drill . Some how the heads in these china mills dont have any girth.
I dunno may be unknown material found a hunk of steel at work ( co worker brought in ) thought it was tool steel cut it up to make a set of parallels dont know what this stuff is . Fly cut it at work on BP wants carbide speed under 1k burnt my arms , put holes in a spandex running shirt Lol.. even w/ fllood coolant and with minimal cuts/ rpm (slowed down) to make brown chip.......... its some hard stuff. Still dont answer my Q does a geared head type mill rumble in head at low speeds? Ya think it;s it Bc its only a china made mill or other?
Yea Pix man Howd I know u were gona ask... Its the China made idexable mill cutters I purchase from Shars. Ah ha yup not the best choice , I believe I posted all the pics of my new tooling when I got the PM25MV i do have other cutters 3/8-5/8 size with APKT stye inserts have to give them a try see how they perform and how the mill behaves . Btw I read allot what you wrote about idexable mill cutters and respect your views .Not sure why my first mill job in steel sounds a bit sketchy .However I do have good quality inserts in them tho. Hmm... Any other thoughts other than tooling ?
