Roughing as it should be done (cnc milling)
#cncmilling #cnc #CncFrezar - Навчання та стиль
Hi guys. This was such a simple job but an awful lot of mess. Now, after roughing, the part goes for hardening.
Yeah gotta shovel a ton of chips after that. Been there done that ^^ An good job turning the thing with the forklift and not the crane. A ex co worker of me once almost tore down our 5 ton ovearhead when he turned around a chunk around triple the size of that thing (and nearly exactly 5 metric tons of weight) And very nice to see some proper feedrates for roughing such a chunk :D
You call this a simple job? Nicely done as always. 👍
@@ChrisMaj OK. Dziękuję przyjacielu.
@@mattweisbart4061 It is a gravity form.
@@mattweisbart4061 looks like another gravity mould. Basing that off the feed and filter slot that were being machined at the end.
People tend to forget how difficult it was to make something like this before cnc machining. Multiple men would be needed. One to machine out the main block. Multiple tool makers to make the different inserts, like corner blocks and the central form. All the inserts would have to have bolt holes and the main block would have to have matching bolt holes for fastening everything into place. That is after everything was ground to size after the individual heat treatments. Then hopefully everything was done correctly, that is the initial engineering and drawing to all of the individual parts being made correctly. Yes, something like this block could take a well supplied tool room a month or two in order to make. The good old days were a real pain in the ass.
A month or 2? From what I've heard that's bloody good going. I'm told maybe 2 complete dies in a year at a push. 5 years ago we knocked out 12 dies for Aston Martin prototypes in little over 6 months (we were working at about 150% though.. 🥵)
Oh wow to be honest I didn’t i would take that long. Thanks for sharing
Nah. People don't 'forget'. Either they know because they've tried it, or they don't.
I've worked with items this large (and larger actually) although in cast iron, which is a totally different story... both good and bad. The good is it's much easier to machine. Tha bad is it's hell of a mess ;-)
You anit shitting it would, and the next guy who gets it is thinking ah shit.
Pretty clueless comment. This is simple mold done in so called "monoblock" (or "monolith") style, one solid block. Most molds are still done normal/classic way (many separate parts, inserts and so on). CNC (or not) has nothing to do with it.
Yes, it was harder to do on manual machines, tracing etc.
But knowledge and skills were higher back then among mold/tool-makers.
Modern CNC guys often lack basics. Mold is "done", but doesn't work properly.
Machining a mold is only one step. Then you have assembly/fitting, startup, trials, maintenance and repair (and "monoliths" are harder to repair).
So enjoy watching you guys work!
Watching your videos is always so relaxing. You make amazing parts that i could only dream of making, very impressive! It looks like you are having a lot of fun while doing it as well.
Greeting from a Swedish machinist :)
Thanks friend
L👀K at those PERFECT blue horseshoe chips!
That steel is butter to this mill!

You make more chips in a Day than I make in a month 💪👍
Very nice work guys! Always a pleasure to watch your video's. Thanks for sharing 👍👍
Thanks
Great video. What kind of clamps are you using for work holding? They seem stiff 👍
Awesome video, on and machine I use I find a 100mm tool with 20mm diameter indexable tips. In the right grade of steel we get up to 3000mmpm feed with around 580 to 600 spindle speed quite comfortably taking 2-3mm deep cuts at around 60-75mm step over. Investing in a right angle spindle head could also dramatically increase productivity when roughing the sides.

For what is this mold used for?
Die forging, pressed metal sheets or something totally different?
I am 73 and did field service on cnc for 30 years I had my own machine shop for 5 years and hated small business, I now do 3d printing and cnc routing for fun, friends send me a photo, can you print, they have no understanding what goes into a stl or gcode file, I tell them to buy an epson printer !!!! its to bad good object scanners are pro only $$$
Nice work!
Merry christmas to you and the guys! =)
Thanks friend
good job CncFrezar
Thanks friend
Nice work, with the exception of the lifting, for the possibility of the chains slipping toward the center. Maybe a couple of boards as improvised spreaders.
Thanks for sharing.
I agree very poor lifting there no bites to stop it falling or slipping
My nightmare is that i get a job like this but have to do it with only one HSS end mill :)
Could be worse, boss could hand you a 10" bastard file... 😕😂

Are you making this for a die trim press? It does look like a part to go in die trim press and make some kind of parts? Great video.
for casting
It would be nice to know what it is been made in the begins
Does that get ground to final spec after hardening or are you able to machine it still?
Hi. We continue only when it comes from hardening.
Great job!!!
Please tell me what is the approximate processing time for this form?

Finally a normal meaningful comment!
@@CncFrezar
I have never claimed to be normal. For example, I spent my Saturday morning watching you guys turn a 2 ton block into a 1 ton block & 1 ton of shavings.
What have I become?
@@digitalradiohacker It is OK. You have my sympathies.😀👍
Awesome 🤤😎! Greetings from Germany
Thanks
Nice! I have a question about rough plunging; is it really not faster, with less tool wasting and has less load on the machine?
It's probably faster. But it's more convenient this way.😁
It's not. Side milling is almost always the fastest way for removing material. Tool wear is about the same.
@@paulgrosfeld5297OK. Less load should be a better cut which results into longer tool live and/or a faster cut. Since you cannot drill full holes to remove all material it my need a special strategy , so I understand to do it the conventional way. It would be interesting to compare both in mass production. My thoughts.
Guys imagine this piece of plate sitting in the shop for a week, boss says "x y z is more important than that".
Another week goes by "we still have time for that"
Today: "Alexandr this is very important and very urgent!!! Can you make this till tomorrow?? Dont mess this up!!!"
Also alexandr: *calls in sick tomorrow*
Always so funny-looking when the tool looks way too small for the spindle :)
I’m most impressed with that wooden pallet at the beginning…
At least something 😀
@@CncFrezar 😉
cute little millhead for such a big part
So I have no idea about CNC machining or anything but do you guys vacuum up those chips and recycle them? Cause they could be melted back down into a block couldn't they?
Yes, they are recycled
I use 700 feedrate and 2300 rpm on 16 2-cut sandvik. I think, that's good for insert durability. What do you think?
It depends on the material
Cool mold
Nothing special in this industry. Another boring day at the office/toolroom.

Dík. Ja len čo Google translator vyhodí 😀Po anglicky viem len madr fakr.🙂
Beautiful blue chips
What place do you guys buy your bits from? Also, where is your shop based out of?
Hi. We are from Slovakia.
I miss machining steel I only machine Pure copper at my job, any particular reason you don’t use coolant? I never used coolant machining steel because of the open machine it would make a huge mess, also if you don’t have good flood coolant it will chip your inserts faster. I’m assuming this part is for mould making ? I do all semiconductor work,
You assume well, it's a form. We use air instead of liquid, it's better.
@@ShainAndrews yeah that’s called ceramic inserts, but go on about how I might not be a machinist because of one statement and be an asshole for no reason when the producer of the video stated I was right that air is better than coolant in this situation. He isn’t using ceramics here, that’s obvious . I see from your comments on other videos you just stir up shit on other pages for no reason.
Nice chip
Fkn beautiful ❤
zatial len hrubovanie .. bude video s dokoncovanim tvarov ?
ptm tie tvary viete aj pomerat priamo v stroji sondou alebo v akej tolerancii su tie najpresnejsie tvary ? Dakujem
Ahoj. Len hrubovanie viac nemôžem zverejniť. Tvary sa kontrolujú na 3D meraní. Ale existuje aj cyklus na meranie sondou ale ho nevyužívame.
How often do you change inserts in this kind of job?
Hi. One blade of a slice for about 4 hours
How often do you have to change the inserts?
About every 4 hours
Awsome video.
How many machining hours did it take?
Hi. Thanks. I can't talk about times.
👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Thanks for the video, awesome nice work. What would happen after stress release and hardening ?, will the surface be grind to measure or using CBN insert for the final cut.
Well thank you. After hardening, it will be milled again.
Why CBN? Carbide is not enough for hardened part? Typical range for molds is 40-50 HRC-ish range, carbide will handle it.
Ahoj pekná práca! Predpokladám, že sa jedná o oceľ triedy 19... Skúšali ste porovnať životnosť plátkov pri chladení s hydrolom/bez ? Viem, že teplo z miesta rezu odvádzate do triesky, len ma to zaujímalo aký by bol rozdieľ, či by to skôr zalepilo hranu na brite alebo by bol výsledok cca rovnaký. Neviem či ste teda používali chladenie vzduchom (cez hadicu alebo priamo cez vreteno?) Ešte sa spýtam aký uhol zanárania a o koľko bol nižší posuv pri zanáraniach do materiálu pri tej 35tke fréze, ktorá bola v 6tej minúte. Na to v akom dlhom upínači bola upnutá, sa zanárala teda veľmi potichu (žiadne pazvuky)
Ahoj dík. Pri hrubovaní vždy používame vzduch a na tieto plátky sa aj nedoporučuje emulzia. Je to lepšie aj preto že ich odfukuje preč. Skúšali sme aj emulziov plátky od Iscaru ale životnosť sa nijako nezlepšila. Fréza sa zapichuje po uhlom 5 stupňov. Tieto plátky od Palbitu sú výborné na nekalené mat a na slabšie mašiny. Majú trochu ostrejší uhol čela tak idú aj potichšie. Na kalené používam radšej Pokolm.
@@CncFrezar áno pokolm je na kalené roboty super 👌. A pri zanáraní posuv zostáva rovnaký?
30% posuvu
@@CncFrezar ďakujem 👌

Nice job! So many questions Like how much stock to leave did you do prior to heat treat. How much did it potato chip removing that much material? Nicely done!
Hi. We removed about 1000 kg of chips
Mám otázku, riešili ste niekedy odstraňovanie dráh po nástroji, ktoré vznikajú na kuse ?
Ahoj. U nás to zabrúsi nástrojár
@@CncFrezar kolko sa necháva prídavok na to zabrúsenie ?
Why not rough out with a 315mm 45° indexed face mill, mid rough with D50R0.8.
Then use a bull nose end mill to finish it all off, maybe append another finishing pass with a new tool for very tight tolerances?
This looks like a job we could confidently cut the machining time in half.
With larger cutters, the spindle bends a lot. That's why we don't use them.
:D nojo to nechces uklizet, krasna prace, ty feedy pouzivame taky, ale na podstatne mensi kusy :D . kolik byl strojni cas ?

Polerujecie formy sami? Jak jest u was z jakością powierzchni po wykańczające obróbce, zauważyłem ze często wykańczacie kształty głowicami kopiującymi na bardzo długich wysięgach nie ma zadrgań na powierzchni? Widziałem ze korzystacie z cimatrona jak wobec was wypada na tle innych programów CAM/CAD przy programowaniu skomplikowanych kształtów form?
Jeśli była by taka możliwość miałbym do Ciebie kilka pytań na priv, jestem programista i pracuje przy formach wtryskowych w środowisku hypermill
Cześć. Tak, sami polerujemy formy. Mamy do tego narzędzia. Czasami przy większych obciążeniach jakość powierzchni pogarsza się. Zajmie się tym narzędziowiec.Cimatron specjalizuje się głównie w formach, moim zdaniem to doskonały cad/cam.Ale mogę go porównać tylko z EDGECAM, ponieważ pracowałem nad nim 7 lat. EDGECAM jest naprawdę słaby w porównaniu do Cimatrona

Why do you not use coolant, is there a reason or is the machine not equipped with it or is it a special steel? Also how long does a part like this take to manufacture, must be days. Greetings from germany
Hi. We use air cooling instead of coolant.
if you use those cutters, air is better for tool life.
Typical stupid comment. The answer is (in most cases): you can't see anything with coolant, that's why people on UA-cam film without it (and morons comment: "no coolant?")...
Step 1: invent casting. Step 2: profit. :)
This is for a space ship I hope 😄
Yes, but I must not talk about it

It looks like a mold plate to me, an A-plate to be exact, I've seen a lot of them. If it's a die-cast mold, they'll be in the holder blocks/retainer.
@@CrazyTony65 It can be, I'm not arguing.
Ball cutter finish
Hi risk job, hard to manage
it's alright
What is it? 🤔🤔🤔
Mold for casting.
Only using inserts? That's going to introduce a ton of tension in the material. Best method is using high feed endmills. Usually they've got chip breakers grind ito them and they can go up to 0,25 mm per tooth with full depth of cut at 10% radial. Way less tension and most of the time even quicker
Would be unusual to use endmills for roughing. And now at hardening any stress will relax.
Watch (and read titles) carefully before commenting. This is only roughing stage...
"Tension" (you meant "stress"?) is not your problem/business.
