Title: Milling: 3/4" depth of cut, shifting 300 cubi inches per minute
Post by: andyf on June 19, 2013, 07:16:39 PM

This is how to shift unwanted metal quickly:

That would certainly fill the workshop up with swarf quickly. :bugeye:

That's not swarf - that's bar stock.

Watch the lefthand side from 2.00 to 2.10 to see the swarf brush catch fire.

There doesn't seem to be any coolant.

I love seeing the chipping "grow", from right to left.

The Tip Rep always insisted, no coolant. As this creates rapid temperature changes at the tips cutting edge. Causing cracking..  :smart:

Hi Andy,

             That machining center is a nice bit of kit, it would need to be capable of those metal removal rates to justity its initial and running costs. Wouldn't surprise me if it was running 24/7.
                                                                                               Nice to see some real engineering.
                                                  Cheers David

Running either carbide or ceramic inserts ive learned that u need chip clearing but no coolant.  The coolant creates microcracks by shocking the surface.

Next to that machine you need a skip!

Those chips are bigger than the raw material i use for my big stuff  :doh:

That's a perfect mate for my 7 x 14 mini-lathe!

Aye, when i was a lad and bits of metal that size came in for work i was given a file, a square, a scraper and a 12" rule and told to get on with it !

PS :  It was a bastard cut file though .   :)  :)  :)
