Greetings; One of the things I have not yet learned is how to get the most swarf from a given milling tool. I have a tendency to go slow, so the swarf is sometimes so thin it settles like snow flakes when it is blown away from the work.
Obviously this is wasting the cutting edge of the tool, dulling it prematurely. So when my fresh shipment of 1/8" mills gets here, I would like to be able to have it throw thicker chips and far fewer of them but remove lots more metal before they dull. I'm going to rig me an oil squirter from an in tank auto fuel pump to try and keep the mill wet. With a tuna can under the workpiece I can catch most of the runoff, and maybe even filter & recycle it. Details to be invented yet in the finest of shade tree mechanic methods of course. ;) Assuming I keep the area wet with cutting oil at a high enough flow that I don't wind up with a muddy slurry, but do have enough chips to act as a wick and keep the mill wet from the cutting oil they absorb (or the oil level in the tuna can is high enough), and the 1/8" 2 flute carbide upcut spiral mill is turning 2500 rpms, how fast can I feed it while doing a 0.020" deep cut per pass without breaking it? Slower and deeper, or shallower and faster for best tool life? -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
