CNC Milling a pressure frame out of an 100kg Block aluminium.

We mill a Pressure Frame out of an 100kg Block aluminum.
Make on my Hurco BX40i

Nice work but I have suggestions you have to start with larger dia tool like 25 bull R 0.8 then move to 12 endmill then move to 10 endmill . This process leads to reducing the cycle time and increasing the tool life time . Hope you try it.❤

[@oskarejsmont]

you could drill multiple holes inside edge of through holes then mill it flat and save internal material in nice pieces.

[@airgunningyup]

he could run a contour op on the inside with tabs to save the pieices, but he then needs tyo go back in for another op to clean the inside walls. Jobs this big generally pay soo much it doesnt even matter.

[@oskarejsmont]

@@airgunningyup i don't think contouring that deep is realistic.

[@roguecnc788]

Was there deflection in the part after you released the vices?

[@irish-simon]

why didn't you get it water cut first ? seems like a waste of machine time

[@SirHackaL0t.]

For the amount of material you remove I’m wondering if making a casting would be cost effective for this. It would reduce machining time greatly. :)

[@kevinleeman5672]

You are not wrong, but I guess it depends on the quantity. If it's a one timer, creating a negative of the casting can be more cost uneffective, than using a simple block

[@dravemaker]

I'm assuming there too, @kevinleeman5672 . In addition, it would increase the lead time considerably. With the milling cutter used, it only took about 2 hours to rough everything.

@@dravemaker do you recycle the chips afterwards?

[@dravemaker]

@@matiastripaldi406Yes, I'm selling these to a recycler, and I'm getting a lot for them at the moment

[@owievisie]

I would waterjet the contours with 5 mm offset so I only have to finish it

[@jimsvideos7201]

Also why not put a hole all the way through those pockets to drain the coolant?

[@dravemaker]

Good question, I honestly haven't thought about it. Would that be an advantage?

[@gerrit2107]

@@dravemaker It might be an advantage if it also flushes some chips out, that might reduce the amount of recut chips

[@CncFrezar]

Very nice! I'm interested in what kind of vises you use.

[@dravemaker]

Hey, that´s the 120mm version from Atorn

@@dravemaker where could i find that?

[@lowtus7]

What would be the approximate cost of a billet like that? Nice work!

[@dravemaker]

That always depends on the current aluminum price, which is fluctuating a lot at the moment.

[@DittersGustav]

Nice job! What is this pressure frame used for?

[@dravemaker]

Thanks very much. The frame is part of a thermoforming tool.

[@HeadyCS]

Nice Job, I would be interested in the manufacturer and type of the 16mm insert milling cutter and shank at 4:46.

[@dravemaker]

Hey thank you, the milling cutter is a shell milling cutter from Aura Frästechnik. I mainly used this to smooth out deep contours.

[@Siguard93]

Nice job 👍 what brand of end mills do you use?

[@dravemaker]

Thanks! I mainly use end mills from Atorn, Garant and Aura.

[@BHAMAAydan]

How much does it usually cost to use the service for a stuff like that?

[@dravemaker]

Hey, thank you for your interest. But unfortunately that's not something I want to write here in the comments. But you are welcome to contact me using the details of my channel.

[@jimsvideos7201]

Shiny.

[@dravemaker]

Thank you.

[@pr00009]

no way in hell this was a 16 minute job

[@FireGodSpeed]

Why are you using a small endmill to rough out big amounts of material, where you could easily use a bigger tool? Kinda unproductive..? Like look at the outside features could have been done way faster with a bigger tool.. (and roughing out the pockets)

[@dravemaker]

Yes, there are certainly large cutters that would be more effective. But in my case it is the most effective roughing cutter I have. It may be small, but it is specially designed to process a lot of material in a very short time and, above all, in very small chips. That is why this milling cutter has a material removal rate of 750 cm³/min. I also have large shell milling cutters, but they only get to 300-400 cm³/min. So it would take twice as long and I would have to constantly clear the machine of chips in between. With the milling cutter used, I don't have to because the chips are so small that they can be rinsed out with the drilling emulsion without any problems.

@@dravemaker You're doing what needs to be done with whatever tools you have on hands. I work as a machinist too doing prototypes all day long. I never run multiple parts and do a TON of different parts. I have my "go-to" tools that will work for most jobs just like you. The cost of getting special tools for just one or two jobs rarely pays off. You clearly thought about your process and got a working part out of it. If the customer is happy - youre prob happy too =)

[@dravemaker]

Hey, thank you, I couldn't have said it better. Just like you, we almost only make individual parts and then always choose the best from our available tools. The production of individual parts is a nice area to work in, you get new challenges every day. As you said, when the customer is happy, I'm happy too. Especially when the customer gets it quickly, he is even happier.
