When buying a m560v, would you recommend to upgrade to a 50 taper spindle, slightly lower Rpm, 12kRpm vs 15kRpm, but larger bearings and a more ridgid tool holding.
It would depend on the application and intended use. If the majority of machine use requires large cutting tools and heavy cuts, then yes. But as you can see in many of my videos, the 40 taper spindle is no lightweight.
@@BrianStall Thank you for your response! Today we have both MX-45 with 40-taper and the larger MX-55 with 50-taper ,and the spindle power of the MX-45 is quite limiting, but the power in a 40-taper spindle of the Genos M460 and 560 seems to be far superior to the older Okumas. One thing that I am a bit worried about with a 50-taper M560 is that the spindel is harder to reach when loading a heavier 50-taper tool.(because the spindle doesn't move in Y-axis) So how easy is it to load tools directly into the magazine, taking into account that the magazine have random placement of tools?
Yes, it's a Blum non-contact laser. I am assuming you are referring to the Renishaw OTS. OMP40 is the spindle probe. The Blum laser will allow you to measure features on tooling that you can't do with mechanical setter, like form, , flute count, radius shape, etc. I think the stated accuracy between non-contact and contact setters are nearly the same. Renishaw as well makes a non-contact tool setter. Hope that helps.
@@BrianStall Are there any particular applications where a non-contact setter would be better than the contact setter? One instance that comes to mind would be micro tooling but I'm curious if there's anything else. Do you also know any info on the price difference?
how does one learn to setup and run one of these? I only have 2 axis lathe experience with no live tooling and having a hard time finding someone to hire and train me on 4-5 axis machines
5-Axis Composite, parametric pattern. I also did just bi-directional cutting at a very fast feed rate, which produced much better finish, cycle time, and part quality.
True, could even be said for 5-axis lathe. But this is not a real part, just a machine demonstration showing the broad machining capabilities of Okuma M560V. You can heavy cut or high speed machining.
Because this is a cutting demo, showing various methods of cutting strategies and machine capabilities. As your question suggests, there are many various ways to cut parts and materials. This demo shows that the Okuma M560V can do it all.
Glad to see your still putting out videos. What software do you use to get speeds and feeds? I can program like a pro but I struggle with speeds and feeds
Work hardening happens due to excessive contact with the tool, chips, and work piece. Its applying more heat to the entire system. The quicker the action of the chip being pushed/pulled away from the material the less heat builds up.
We have one in Dayton that we are doing turnkey on. Michigan office is working hard at getting one on their floor for July. A large quantity will start arriving early August to port. Where are you located?
It's pretty good. It is very similar to Fanuc. I like better Fanuc, especially for operation. Not as much as Okuma OSP. Has some great features for setup offsets and tooling. We are receiving machines with the M80 now. Has touch screen and some better graphics.
For clarity, I mean the rotational speed of the surface of the tool, called Vc, the speed at which the edge is cutting into the material. Not the RPM or the feedrate :) Officially, steel has a very narrow range of Vc that it can be cut at, around 200m/min, which is about 8000IPM, but you're going over twice that speed with good results, which is interesting! This is according to a moderately old handbook I have, so it might be wrong with it comes to modern techniques :P
@@bluustreak6578 Gotta say mate, you made yourself look pretty dumb in front of all of the people here. Obviously we know that rpm=vc, have a look at radial chip thinning, and how it affects your feed.
But RPM is not Vc. Vc= RPM*ToolDiameter*pi Vc is the speed that the cutting edge on the very circumference of the tool is travelling at, and while it is indeed dependent on RPM, there's more to it than that. Steel likes to be cut at a specific speed, and that cutting speed is meassured in Vc. And yes, the feed can be increased a lot with a small Ae(radial engagement) due to chip thinning, however, this does not affect the allowed Vc value. EDIT: just for clarity: Feed speed(Vf), RPM, and surface speed(Vc)(which is what I call rotational tool speed) are three totally different things
Hi Brian, thanks for the video, if you cam make comparison test between Hardinge Conquest V1000, and Doosan 5700. I know that they cost almost same 80-90K, but which performs better and more rigid.
Yes it is. Mill is only initially assembled in Taiwan. Then they are shipped to Okuma Japan for final assembly, power-up, and inspection. Therefore made in Japan. Sounds like you may have been mislead some.
Next week I will be learning this system. Our company just received an Okuma LB3000 EX II. The old workhorse it replaced, measured its internal memory in characters!
Also you use blue swarf? is that the software you would recommend to make finding optimal speeds and feeds faster or is there a quick software I can download?
No, there is a kit involved. Check out BlueSwarf.com They are doing some new work to create dashboards with tool and holder 3D model. You machine would need to be tapped with kit and artifact.
how do you like the fahrion holders for a cat 40 machine? I'm trying to find quality but coat effective tool holders that perform at speeds and mrr like that in your video. I'm in the us and using Haas machines using hem toolpaths. cheers
I've used Fahrion Centro P tool holders on several Okuma mills and they are really good tool holders. Not had a problem with endmills or drills sliding out of the collet. Just remember to buy the torque wrench tool Fahrion sells separately it will save you from the trouble of endmills getting stuck in the collet. Also the tool Fahrion supplies to loosen or tighten the collet nut is not the best. It is made from some sort of cast aluminium and it will break if you tighten the collet nut too hard. But it's fairly easy to make a new one from steel that does not break.
Rasmus Laursen thank you appreciate the info. just trying to find a good budget set of tool holders that will work is the kind of toolpaths and feeds and speeds shown. in having issues of chatter and vibration with the er32 collet holders and Endmill holders right now.
Imo the best tool holders for high speed machining is shrink tool holders but buying the whole setup to use those are pretty expensive. Next best thing would be Hydro tool holders. Used different kind of those too from Sandvik, Mapal and Kennametal all worked great. Used solve your chatter problems in most cases but at a price -They are not cheap.
There are some other solutions to try, which i have had great luck with, especially for chatter. Look at Pioneer MX/VX collet chucks. They are similar to the Lyndex-Nikken Insider holders.
It's still enough to lower the surface speed ceiling on a lot of tooling. There are a lot harder materials out there sure but it's still impressive to see the material removal rates exhibited here.
that's pretty cool what type of end mill did you used? 3/8 carbide? 4 flutes or 5 flutes or ...? what's your RPM and feed rate? how much are you take off each pass?
