Sandvik Coromant CoroMill 216 Ball Nose

The CoroMill 216 Ball Nose Endmill is a strong endmill concept. Each cutter has two effective inserts, and each diameter uses the same insert type in both center and periphery tip seat. The application concept of the CoroMill 216 is aimed at roughing and semi-finishing of curved surfaces in machining centers, CNC milling machines, and copy-milling machines for die & mould, aerospace, automotive, and associated industries for production of primarily curved surface components. For larger cutter diameters, there is a shank protection insert available.

These work great, sound horrible, just dont plunge cut.

[manword1]

@narcoti well you never know when can i afford it or not

and that is only mech like in business need so i guess yes somehow anyone can afford that if needed in business dont you think^.^

[narcoti]

@manword1 If you have to ask, then you can't afford it.

[manword1]

and the price for this mech. is?

cutting alumiunuim is easily than harden steel

@Polybun No, and that is because of the high clpt. The thicker you make the chip, the more of the heat it can easily absorb. You end up with the chip taking the heat of the cut with it, rather than being absorbed by the cutter or the work piece. This is true of manual machines as well. Typically it is much better to turn slow and feed fast than it is the other way around. That's exactly what is being done in this video.

@fortmcmurraycash Can't tell with it spinning, it kind of depends. Some of those have two inserts that cut the center, some only have one. Now, the ones with only a single insert removing material in the center of the cut have some limitations but you can still push them to .015 to .020 per rev. Carbide is stronger when it's radiused. If you aren't removing material on center, you can go even faster, provided the machine is rigid enough. Cutting with radiused inserts takes more force.

@Polybun whats the CLPT on that cutter? its just that im a manual guy lol...i would be paranoid using a cutter like that for what i do lol....thats all im sayin. im not tryin to rip ur heart out of ur chest....and yes the chips look good but how long would that cutter last using it like that? ball nose generate alot of heat....i guess the chips are blue tho..heats comin off the part but still...i bet that cutter is wicked hot....just seems like its feedin fast...maybe im wrong

[Polybun]

@fortmcmurraycash how so? The chips look perfect, The finish on the sidewall is clean with no chip weld. I would like to know what you base that on.

[fortmcmurraycash]

@Polybun still looks like its loading the cutter up a little much....
