Many factors control what is best. With the right endmill grind, and machine that can keep up with the endmill, 17-4 can run at 800 ipm dry, 15-5 about the same. Even the dreaded "inconel" can be...
The endmills in the videos are my regrinds. The feed rates are from trial and error. In steel alloys under 30Rc I use a sliding scale .025 radial = .015 ipt translating to .250 radial = .005ipt for a...
have they looked at any videos like this one or researched high speed machining. If not, It may not take much to get them hooked. Get them to watch my other videos, I have one posted that is running...
trochoidal paths most likely would be best. 316 ss is part of the 18-8 series of stainless, slightly more abrasive than 304. The part in the video was 304 and roughly the same area as yours....
Overall , they are good machines. The haas controller is basically fanuc style with a few nice improvements. Ask the trainer about programming from dxf files, program restart settings, and the hsm...
Depends on too many factors for an instant answer. Part profile, pockets, thickness, cubic inches to be removed, machine capabilities, tool manufacturer and type of stainless steel would be the main...
Please call Byron again, he apologizes, but he accidentally deleted your number. He can control the hole diameter within .001
I do not know where you are located, but you should call our mits rep. He is the district manager for the southeast. Their drills have worked perfect for us using his recommendations. number is...
According to the specs at aksteel.com, its just a ferrite free version of 17-4. Use carbide tooling with sharp edges(minimum edge prep) and a quality coolant such as syntillo 9913. Myself, I would...
If you have a % symbol at the beginning of the program, try deleting it and see if that works. Your g code is correct.
check with a mitsubishi rep. they have carbide graqes that really do well on thi material
If your are using a coated endmill, .5 mm stepover .25mm ipt 3000 rpm
watch what can be done with stainless at

Watch the video on youtube titled 'high speed machining(really high)"
if this is the way you want to run, contact me.
We just tested our endmill grind on inconel 718 at 960sfm and 250 ipm. here is a link to our video on youtube.

Mitsubishi makes small diameter feedmills that would be great for this. 6mm would be perfect for roughing and then use a .25 finisher
Your problem has nothing to do with the rigidity of your machine. What is happening is the endmill is pulling out of your holder and probably spinning in it . As a rule, I only use collets for...
We tap 17-4 on a regular basis. Use the maximun diameter tap drill, castrol molydee tapping fluid, torque control tap holder, a quality slow spiral tap and run at 20sfpm in and 3x out . works every...
Probably just the harmonics produced by the combination of a 2 flute endmill, not quite rigid enough setup, and the helix angle of your cutter. Going to a 4 or 5 flute endmill for finish should...
.5 slotting cut should be no problem in stainless. 4 flute variable helix, full depth, 150/200 sfm .012 per rev minimum feed. Watch this testing video,feed was .02 per rev, it may help. The main...
3/4 four flute endmill, 1700 rpm 27 ipm no coolant. These are the parameters for most variable helix endmills. depth according to machine power.

The endmill is a straight endmill with a 45 degree helix angle. To run your part out of aluminum I would use a solid carbide four flute endmill with no edge prep on the flutes and no coating, if this...
Carbide endmill, two parts, 1st 1018 steel, 2nd heat treated 17-4 stainless steel. No air, mist or any other type of cooling. The tricks
1550 sfm, conventional cut with carbide, absolutely no...
I would suggest 3 axis roughing with a regular square corner endmill and finish with a solid carbide angle cutter. That way you get quality and quantity with minimal cost. Check out my video on...
I agree completely. With the right speeds feeds and cutters almost all heat can be kept out of the part. Proof of this is on youtube under "high speed machining(really high). .625 endmill 10000 rpm...
A mitsubishi feedmill will handle this with no probem. We use them for plunging and the inserts are relatively cheap.
Check with mitsubishi cutting tools. They have cutters that really move in stainless, will sell on performance PO, and are less expensive in the long run
High speed machining has been around since the 1930's. the link below is to the site that has quite a bit of information about it. Also watch my video on youtube, I think you will find it to be...
I do not know if it will apply to your machine or not, but our new fadals have the fanuc oi and the lock code is 189, 19 is only orientation.
Check out how we run 17-4 stainless. these cutters should do well slotting in 304 also
