Big mold part (cnc milling) 

Thanks

👍👍

Я как-то имел честь с 430мм инструментом работать

👍👍

Ага, да ещё и какая лихая подача при такой длине 😮

@@vithem6685 да подача не маленькая 🤔

Ничего удивительного твердосплавные пластины плюс станок высокой жесткости.

Probably the programmer's work is good, that is, if the operator does not make the program himself.

Ďakujem. Tie vrtáky máme ešte z čias Československa a je ich dosť .Takže míňame čo máme😀. Ten čas čo by nám urýchlili moderné vrtáky nie je pri našom spôsobe výroby až taký markantný takže musíme ich najprv domíňať😁

@@CncFrezar Děkuji za odpověď.

👍👍

Congratulations😁

Im using mill the finish walls max 140 mm deep, above i usually finishing with the bigger milling cutter whats fitting the radius in. We have some cutters calld ZCCCT D50 R0.8, S1800 F1200 and 0,7-0,5 ap, and the surface and parellel is great.

It is our high expertise😁. It could also be a coincidence🙃

@@CncFrezarFunny, the more you do stuff like this the luckier you get

❤👍

It certainly exists, but we don't have it

Thanks@@CncFrezar

👍❤️

It has 3 teeth and is for finishing

What if the drill breaks and scraps the workpiece beyond repair, after all that milling?

There was already a video about the broken drill😀

Have you purchased the cutter to replace the broken one? If so, have you tried it yet. Is it something new for you, new brand, new type?

чисто для видеосьемок

у сендвика в пособии указано что сталь луше без сож обрабатывать, потому и поинтересовался =) @@CncFrezar

@@ratchetrus Это правда. Используем жидкость только для монолитных фрез.

No1.

Why?

👍❤️

👏👍

I think they are right. But I'm just a miller, so I can't answer that exactly

👍❤️

It depends on what the hole is used for. A core pin hole needs to be located very precisely and have very accurate dimensions, where an ejector hole the tolerances of location and fit are less important. An ejector pin will always have some flash just because of the nature of the ejector pins moving. A core pin hole if sized correctly will be a perfectly clean parting line where the core pin and mold body meet and it will stay that way as long as the mold functions. Jig boring and jig grinding are traditional hole methods. Wire EDM is also a good method for making accurate holes but requires more overhead for machine capable and a machinist with the right know how to achieve accurate results.

Holes H7 and shape +/-0.05mm

It depends the type of plastic you put on inside the mould, abs need more precision than policarbonate for example

Well thank you. But I can't talk about times

👍👏

Like nothing😀

@@CncFrezaryou don’t use holders like Rego-Fix Zero-Z ER CAT 50 Collet Holders, I think those would help you keeping some long tools shorter

Using paper.

@@CncFrezar Oh no, you're kidding me 😁😁😁 Do you have one base on the table? Because, of course, sometimes something will break and there is no way to bounce with z0 on the mold In my company they use such equipment with a camera from garant and it gives the value of length and width nice for setting boring bars

@@Adam0855 We also have that device, but it's about 20 meters from me, so I don't want to go there, so I'll use paper.😁

We only check functionality

Axial depth of cut, also called DOC, basicly how deep tool is going each pass...

Это секрет🤐

@@CncFrezar (

Maybe to the ISS😁. I don't know myself

👍👍

Ah right it's the Democrats who are busting unions and creating tax havens for the billionaires.

If I understand you right they way you're talking about would have been a lot harder to fixture and possibly not possible with what they have. Sometimes, it makes more sense to just let the machine work.

@@85CEKR it's doing the same thing but not using the slow face he starts with, and it's not wasting drilling all that depth and just cutting it all out. When you can cut it all the way down and then drill! Wasted time one drilling, Wasted time on using that slow facemill, and then Wasted time on facing the opposite side when you are cutting most of it away because of the pocket.

Not everything, I machine the copper anodes that actually get turned into microchips, one of our parts got bid out to be made in China, it only took 2 months before the quality was so bad the part came back to our company, these parts have the strictest surface finish and cleaning procedures you can imagine, China will never be able to make the highest quality of parts we make in the USA. More likely for European countries to take our parts, they are way better and automation to make cheaper prices

I don't know exactly what you mean

@@CncFrezar how to mill 300 mm deep ?? how to mill 300 mm wall machining in deep??

@@Whhhoo3_3939 There must not be perpendicular walls on the part and you must have good cam software.There must be sloping walls. The more oblique the better

@@CncFrezar can yo make video to mill more than 300mm deep machining opration???????

​@@Whhhoo3_3939Good freaking luck... Thats not an easy feat.
