To anyone not totally used to these endmills and machines, you would envision an endmill flying across the enclosure at 1:24. That's incredible.

[@henmich]

I thought that was aluminum until I saw the chips turning blue... well played...

[@klab3929]

Absolutely awesome! I have become a fan of Guhring milling cutters!

[@TOM-ph7xy]

Music rocks. Nice part. I couldn't try out the milling products yet. drilling is good. solid results

[@kpoplover5619]

For some odd reason this is Satisfying to me

[@kevin_delaney]

Ignore the first minute, but you'd probably enjoy some of this guys machining videos, it's like CNC porn, it really is. Some of the best CNC machining is just so memorizing to watch: kzbin.info/www/bejne/mp3NeWCri7aSf9U

[@Clinteastvveed]

To me these endmills are Art

[@BASH666HD]

try Mitsubishi end mills. Guhring is not bad at endmills. but they are best in taps and drills.

[@Chiltonzr2]

I'd say the real winner here is the machine and not the end mill.

[@deeznutz2646]

And I'd say you're an idiot. Try performing the same thing with a standard, run of the "mill" end mill. Please do and post it.

[@METHIERO]

U can't do that on a Haas

[@hamadal-shuaili9909]

@@METHIERO Hello Medardo Rivera Contreras; What is the cause that haas machine can not do that? Please share your idea.

[@METHIERO]

@@hamadal-shuaili9909 well the main problem is rigidity lf the main frame, i have worked with 2013 Haas machines side by side with old 80's matsuura and the matsuura worked 5 times faster, the job had lots of rouging.

[@hamadal-shuaili9909]

@@METHIERO 5 times ...that's great. There are some conditions which thay can make such this difference . Some of these related to the cutter and some related to raw material. Thanks.

[@therussianmachinists2409]

I think you need a good, ridged cnc to do something like this. I can hardly imagine doing this on the haas I work on. just seems like it will chadder like crazy

[@lineage13]

I mill steel & aluminum faster than this on my cnc router lol

[@MrFuchew]

that steel plow does demand a rigid machine with a lot of torque. any drop in rpm or flex and that edmill will snap

[@Clinteastvveed]

You think you can match the material removal demonstrated in this video on your router? You are sorely mistaken and I'll believe it when i see it. You may cut at faster feed rates, not faster material removal.. Anything can go fast while taking wimpy little cuts. That cutter took a slot depth twice the cutter diameter in steel at 28 IPM. Show me you do that on your "router". Your router better have a 30HP CAT50 spindle on top of a multi-ton casting.

[@lineage13]

Hey m8 just click on my KZbin channel I have alot of videos up already. For slotting and larger material removal rates I run at lower rpms and use my drill press or router. I did some math and my material removal rates are better than a haas u to a 1/4 end mill. Depending on endmill size.

[@lineage13]

Im just comparing my feeds & speeds with a haas with 1/8 end mills. Mine runs faster. fact.

[@ostry599]

for all this movie its still the same endmill ? :D

[@nenadjanjic8070]

I did whit Guhring RF 100 Diver 12mm diametar on Haas VF3 ,all this things whit out any problem,for roughing i did increase Vc to 450m/min --->12000rpm(max on haas) and it worked w/o any problem.

[@josecastromartell1108]

The biggest part on this is the tool cutter and as you see this another level in cutting tools if you have a good programmer you will do amazing parts BUT remember this is a tool cutting add. If you go for steel or Chromium o Inconel is all on the tools guys please remember the overall (money) is in there.

[@barriath8841]

I gotta say I'm impressed with that tool. we sadly have machines that are bottlenecked at 8000rpm and you literally can't do shit with them

[@TheAlexLegolas]

When I started using these feeds in my tehnical instructions all the workers was ready to hit the red button... I say trust me I am Engineer

[@zaknefain100]

Yeah... I never tell people I'm an engineer (MSME)... the confidence goes up immediately.

[@angrydragonslayer]

I say "trust me, i'm responsible if it fails" Most of the operators have had a few too many engineers

[@rgbelektronika-serwisisprz7057]

[@kavivarman86]

what is the spindle speed and feed for this job

[@HolzDennis]

How many times did you changed that Milling Tool? I’m sure this wasn’t always the same tool...

[@mattcaesar5781]

Looks like a mild carbon like 1018. still impressive without coolant. Small engagements for the most part just full depth. The ramp is the most impressive i usually do 5 degrees

[@kevin_delaney]

I think it's more comparable to 4140 to be completely honest, 1018 isn't that shiny, is it? I think that has more chromium in it than 1018. Also, I usually don't ramp, really at all. I'll either pre-drill and then bore out the pocket at full depth (if possible) or plunge a hole with the endmill and then bore it out. I try to wear the corners as little and as evenly as possible, trying to wear the while tool evenly if possible.

[@zaknefain100]

1018 is a pretty gummy steel.. lots of inclusions and not something I'd use for demonstration purposes, but who knows. A good candidate would be a much cleaner steel like P20.

[@zaknefain100]

And yes, this is 4140 according to the video.

[@minhnhannguyen3810]

Can Guhring help me? What is the workpiece material?

What cnc milling machine you are using ? I'm looking for a very accurate (not too expensive) +/- 0.01mm cnc machine to cut some grade 9 titanium, cutting range 2ft x 5ft x 1ft, at least rack and pinion rails and rails need to be laser straight won't bend under 190 lb forces.

That info on Guhring India was intended for another comment/question which followed yours - sorry.

[@tubbytimmy8287]

The feed numbers are very specific. I've always wondered how you calculate those. At 0:40 it says 0,094mm/t - why not just 0,1mm/t? Can 0,006mm really make a big difference?

[@guhring_USA]

+TubbyTimmy There are formulas used to calculate feed and speed tables. You are correct a difference of .006mm feed / tooth is very small and in most cases makes little difference in how the end mill performs. Feed and speed tables are a starting point. Often times minor adjustments may be required to optimize the cut. - Milling product management

[@drewtramp1577]

Something looks funny at the end. The holes look funny. most likely glare from the camera lens. Definitely some beefy cuts. You guys send sample. Lol. What kind of holders were thoose.

[@guhring_USA]

This was Guhring’s HPC milling chuck. You can find more info about the chuck here www.guhring.com/Documents/Catalog/Toolholders/HPC_Brochure.pdf and here www.guhring.com/Tech/GM300TechnicalDocuments/.

[@shiro-r4m]

What you saw in those holes is what happens when you drill with an end mill. An end mill doesn't have enough clearance in its flutes to evacuate chips that are being cut in a drilling motion, the chips get stuck in the flutes, they rub on the surface and get re-cut. That causes a whacky surface finish. A better way to make those holes would be to use a proper drill or by using (also demonstrated in the video) helical interpolation.

[@norbertfleck812]

[@Dimka2]

no its not, if you ever machined anything you would know just by looking at the chip, and the chip color. also if you pause at 00:18 it says what material it is, and with a little google search, the material is 4140 in more common term..

[@codybelk34]

I use manual machines and I’m just now studying CNC so I have a question for anyone that knows, do climb cuts have any effect on a CNC like it will manual? I just see a lot of CNCs making climb cuts and it just always puts me on edge bc that’s just a no no where I work 😂

[@jonathoncoward2210]

no. manual mills have acme screws and nuts which have backlash, some more than others. my birmingham at home for example. turn the handle to load the table, zero the dro and dial and turn the handle backwards it reads .020" on the dial and the dro moves on .021". The acer we use at work is .05"-.07" cant remember off he top of my head. so snug the table and light cuts. A cnc will use a ball screw and ball nut system backlash any where from .003- .005" on the cheap hobby machines (rolled screw and cheap nut) to .001" or less on real machines ( precision ground screw and matched nut or double nut setup) so its very rigid. Plus being servo driven, the screw is coupled direct or offset with a toothed belt so its not going to jump like it would if u get a little happy cranking the handle and start putting slack in the table on the manual.

[@codybelk34]

thanks for the info!

[@ehess1492]

Climb cutting gives a superior surface finish. It’s not a problem to climb cut on a manual mill. If you have a lot of backlash in your screws, tighten your bed way locks halfway snug and just do a light finishing cut in the climb direction.

[@ehess1492]

Climb cutting shouldn’t be a “no no” anywhere - it’s a legitimate technique with a time and place.

[@probitbiswas725]

@@zaknefain100 damnit

[@57_te-babhijitsatpute81]

Why there is no coolent

[@frp1276]

It is becoming commonplace to mill steel and other difficult to machine materials without coolant. Tool life increases as thermal shock cycles decrease.

[@danking3093]

What speed is the cutter running at?

[@guhring_USA]

The speed at which the end mill is running varies based on the type of cut. The speed is posted throughout the video as Vc in m/min. To calculate the SFM, multiply the Vc x 3.28. For example, the first profile cut is taken at 302 m/min (302 m/min x 3.28 = 990 SFM).

How many parts can you produce with 1 end mill cutting the same way as in the Demo.

[@hamsteaks5541]

I have done this type of work for over 10 years and I can say NOTHING has come even close to these end mills in terms of durability and simply "getting it done". Worth their weight in gold.

[@zaknefain100]

End mills are consumables, so what's the worry in consuming them? What's it cost to make 'x' feature(s) is the better question. Looking at tool cost alone is a backwards approach, and since tool life is variable... in that it's directly proportional to surface footage, you can dial up or down as necessary to get through x number of cycles before replacing. All of which requires some cost analysis. I see a lot of folks getting hung up on tool costs though, even when the cost of tools is less than 10% of the manufacturing costs...
