Thanks so much!

I wish I knew about this channel when I was starting to learn about machining

Having produced many thin wall components out of oxygen free copper...I have to disagree with your points on copper. Some alloys of copper (type 1 -free cutting, type 2 - short chipping) are easy to machine. Low alloyed copper (Type 3 - long chipping), especially oxygen free copper are NOT easily machinable. Great ductility and excellent cold-workability are not characteristics of an easily machinable material. In fact such properties leads to rapid chip welding back onto the part or on the tool as Built Up Edge (BUE) and chip packing due to it's great ductility and poor chip control. Tooling for production of oxygen free copper parts involve highly specific coatings for example, Diamond-Like-Carbon (DLC) coated tools. New machine functions like Low Frequency Vibration (LFV) cutting is introduced to the market as a solution to some of the issues dealing with copper. Conventional cut tapping is a great way to break some taps as well. Getting that tap out was how I got my second job as a machinist.

Très très très intéressant! Bravo.... Du Canada.

You have a terrible misunderstanding about that pipe used on the computer heat sink you showed, that is a HEAT PIPE. It is hollow and uses a vacuum inside and a small amount of water, it does not transfer heat through the metal much, but rather a vapor inside the hollow center moves the heat. That heat pipe is far thinner than normal, but you can tell it is a heat pipe by the tear drop end where it was welded shut.

[@BushidoBrownSama]

it can transfer heat through the metal in two scenarios when the heat is too low to kick off the evaporation process & heat pipe dry out when the heat is too high for the vapor to condense back into a liquid though heat pipes are typically chosen & grouped together to avoid these scenarios for a given application.

These kinds of videos are awesome. They are very educational and it tells the story. I really love your videos, I learned a lot from them. I'm very new to CNC machining and mechanical design. Recently I learned that you can remove the machining toolpath with the lapping process. I would like to see a video about the CNC machine that you're using and some more information about it. If you can make it of course :). I have one more question. Where can you buy end mills for a small CNC router like yours? I have access to one "homemade" CNC router and all the tools they have are dull. I would like to make some parts out of wood as well as from the PTFE or even aluminum. Is there a "universal" tool to cut all of these materials?. Greetings from the Bosnia and Herzegovina :).

Great video

[@Jameshazlett]

I am amazed on the info, the detail, the accuracy, and when he called copper an "alloy". Guy probably uses 99.999 pure stuff. Still amazing video. Loved this content.

[@daniel_6741]

That milling strategie is a weird one never seen something like that because of the low percentage of tool engagement while milling. Why don’t you deburr the part right in the facing setup?

[@jayppop3333]

I've been machining niobium supposedly it's like soft copper

[@broughttoideas]

Could you go over stainless and titanium

[@ProtolabsMFG]

We do not have one on titanium yet but here you can find our video on stainless steel: kzbin.info/www/bejne/aYXWooisj8l5adE

What is a purity needed in copper for good heat desipation

DIfferent ways of protecting metals from corrosion

[@Hitendbz]

what kind of cnc should i get

[@adhanonoi]

Sorry to late..... Every day i made part use cnc..... Bike part...
