Roughing as it should be done (cnc milling) 

Hi guys. This was such a simple job but an awful lot of mess. Now, after roughing, the part goes for hardening.

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.

So enjoy watching you guys work!

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 $$$

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 :)

1:52 In soviet Slovakia, freshly milled surface flattens YOU!

L👀K at those PERFECT blue horseshoe chips! That steel is butter to this mill! Michael 🇦🇺

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 👍👍

Great video. What kind of clamps are you using for work holding? They seem stiff 👍

Nice work! Merry christmas to you and the guys! =)

good job CncFrezar

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.

Awesome work!!👍🏾

For what is this mold used for? Die forging, pressed metal sheets or something totally different?

My nightmare is that i get a job like this but have to do it with only one HSS end mill :)

Салют коллеги!!! Хорошая работа!

I’m most impressed with that wooden pallet at the beginning…

Awesome 🤤😎! Greetings from Germany

It would be nice to know what it is been made in the begins

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.

Cool mold

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*

Amigo mais uma vez um ótimo trabalho. Só uma pergunta, como eu encontro pra comprar esse tipo de fixação que vc usou??

👍 Pekná práca

Always so funny-looking when the tool looks way too small for the spindle :)

Nice chip

Muy buen trabajo!!! La máquina es Visión Wide??

cute little millhead for such a big part

hello，could you tell me the cutting parameters for the very long tool with shrink holder during roughing operation in the first coordinate. by the way,what's the material for this part? recently I will machining the Titan material with 360mm whole length.

Pěkně kucí 😉👊

Super videa, platky jsou inserts ne slices, to se pouziva u dortu. :D Delam uz leta obrabeni ve Skotsku, kdybys potreboval pomoct s nazvoslovim, rad poradim. ;) Slovnik neni optimalni.

Fkn beautiful ❤

Beautiful blue chips

Does that get ground to final spec after hardening or are you able to machine it still?

Hustý, Děkuji za video. Jaký máte ŘS ve stoji?

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?

How many hours?

I use 700 feedrate and 2300 rpm on 16 2-cut sandvik. I think, that's good for insert durability. What do you think?

Hi. Anyone suggest what type of clamping is used here because I'm facing many problems on work holding since i use bottom screw lock on base plate method

👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

🇮🇳

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.

Nice! I have a question about rough plunging; is it really not faster, with less tool wasting and has less load on the machine?

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)

Hi, I am curious about what happens with such a lot of steel scrap chips. Are they recycled? Best Regards from Brazil. Dieter

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,

what is the actual part you made?

Vision wide?

Поехали!

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

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

What place do you guys buy your bits from? Also, where is your shop based out of?

No oil and water?

Looks nice. What’s it for?

Awsome video. How many machining hours did it take?

can you send the data as xt

Дружище можешь модель боковых прижимов выложить если есть, хорошая штука

How often do you change inserts in this kind of job?

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!

Pieknie, jak długo trwała obróbka ?

Mám otázku, riešili ste niekedy odstraňovanie dráh po nástroji, ktoré vznikajú na kuse ?

漂亮

:D nojo to nechces uklizet, krasna prace, ty feedy pouzivame taky, ale na podstatne mensi kusy :D . kolik byl strojni cas ?

Zdravím len pre moju zaujímavosť. Ake bolo ap pri čelnom fr. Plochy?

How often do you have to change the inserts?

Who makes the clamps on the table

what spindle load did you have in the roughing?

What software do you use for programming

What is it?

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

what vice do you use and where can i buy

Just out of interest how long was the cycle time?

This is for a space ship I hope 😄

3 d finish die ka video

how long have you milled?

how much does a 1.9 ton chunk of steel even cost ? im guessing its double scrap prices, maybe triple

Step 1: invent casting. Step 2: profit. :)

show us chips flowing out of the chips conveyor

What is this part used for?

Isn't better to cast rough product and then finish it on CNC machine? BTW, are you a Czech?

How many hrs

What a fat Workpiece. Well done, but why no colant? filming issue? I go faster with coolant. But my biggest is 12mm dia, but most under 6mm for small pieces. You need always coolant or your small cutter glows.

Что это получилось?

What is being made here?

parece que aun no esta finalizado

Hi risk job, hard to manage

Where are the leader pin holes?

Ball cutter finish

What is it? 🤔🤔🤔

We are making the case to mount this device... sorry guy i can't use english

How come you don't use coolant.

Plastik kalıbı tecrübe var elhamdülillah

А где табличка "Экономьте металл"?

Please don’t switch between units of measurement. 1.9 tons to 900 kgs. ?

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

why no used water?

U seem to be needing more horsepower.

No cooling fluid?

가공속도가 너무 느리군요? 아주 느린 feed?
