    Speed/Feed for Turning 4140 - Practical Machinist

    Mar 16, 2011 · An annealed 4140 behaves damn near exactly like a crummy 1018 or A36, run that stuff FAST and hard. If you are getting deflection and need to hold size and you're using a smaller DOC, run it faster. 800-1000+ sfm on 4140 shouldn't be a big deal. A large DOC and as heavy of a feed as you can use to maintain your finish specs.Cutting Speeds - LittleMachineShop, 4140 steel cutting speedCutting Speeds. Determine the spindle speed for turning, milling, drilling, and reaming with these charts and cutting speed calculators. Turning speeds are adjusted to the feed rate of the mini lathe (0.004/rev.), a depth of cut of 0.040, and a tool life of 180 minutes.Speedy Metals Information for 4140 Decarb Free Annealed4140 has a machinability rating at 66% of B1112. Average cutting speed 110 ft/min. 4140 is difficult to weld, but can be welded by any of the common welding practices providing section is preheated, and stress relieved after welding. HEAT TREATING. 4140 has a hardening range of 1525° -1625° F

HEAT TREATING. 4140 has a hardening range of 1525° 4140 speeds and feeds - Practical MachinistSep 17, 2006 · The main problem you have with HSS cutters is heat build up. If the cutter does "burn" you can easily work harden the material. Then when you replace the cutter to restart cut, it hits the hard spot and you have another cutter with problems. I feel it is better to baby it and save tooling, if at lower speeds its cutting well then speed it up a bit.Machining 4140 | The Hobby-MachinistFeb 06, 2018 · Cutting speed for 4140 is about 50 fpm for HSS.

    Machinable, heat treated 4140 - The Home Machinist!

    Dec 25, 2009 · Milling, drilling and boring always seems to have bright streaks in the machined surfaces caused by one of the alloys. It can be machined with either carbide or HSS cutting tools. The counterbores, drills and taps you already have will work in 4140 pre-hard. Use cutting speeds similar to A-2 with coolant or cutting oil. Any steel supplier should be able to get any size 4140 pre-hard you need.Turning 4140 Alloy Steel - Practical MachinistSep 03, 2014 · At a previous job I turned tons - literally a ton or two a night - of D2 tool-steel, and got to spend time experimenting with cutting parameters, learning what you could get away with. We had a box-way Okuma Captain lathe, with a big-bore, 2-speed winding type main spindle motor, and I believe it was rated at 20HP continuous.Cutting Speeds & RPM CalculationsThe greatest indicator of proper and improper cutting speed is the color of the chip. When using a high-speed steel drill bit, the chips should never be turning brown or blue. Straw-colored chips indicate that you are on the maximum edge of the cutting speed for your cutting conditions.

I've machined mounds of it with M2 cheapo HSS. Better tool steel will last longer in a given application but a quick stoning will put a fading tool back in service without removing it from the holder.
