9:50 if the sound doesn't give you a hint where the optimal setting is, then watch on the chipsize/form.At 8:50 looks good to me. Whats your reason to switch to 40$ tools? i focus more on the midleground performance/money. These Tialin-tools are like that (nr.4 on your list) Did you already tested Wolfram carbide burrs, you can easily work on hard steel with handtools, I was suprised myself. Maybe it works on CNC too.

[@brentonk461]

Worked as CNC programmer operator, both milling and lathe, done my apprenticeship as engineering Toolmaker for a decade and half, I don't do it anymore, definitely won't work for a boss ever again, but I would'nt mind getting a little machine like that one for myself, I can't imagine it being highly accurate, but it seams to do alright for its size. Line left for finishing. Ti-Ni coated hss for aluminium. I don't need to test it, I know it works. For a machine that is Not ridgid, I have found line right can be helpful when roughing out to prevent the tools from digging in. Also The type of flood or mist coolant, cutting fluid you use is critical to achieve best finish, although you can cut dry, but it is more likely to fur up.

[@DavidM2002]

I've been doing hobby CNCing for about 15 years now and recently went back to the basics. I experimented with end mills, feeds & speeds, etc. But the one thing that I found that you will give you the biggest improvement on your finish is clearing out those chips. I use compressed air routed through LocLine flex tubing with a very fine nozzle. Just a few pounds of air pressure is all you need. Yes, coolant / lubricant and the right end mill are important but unless you get those chips out of there, they will just be ground between the cutter and the work piece. One further step in that regard is when doing the initial cut, set your software to leave a finishing allowance - I leave about .030". Before you make your final cut to remove that finishing allowance, get every last chip out.

Dear Sir There is a problem in your tool route Notice: 1. Go along ======> 2. Go backward

Hi, Happy New Year! You steel working whit this feeds and speeds? Try 2 mm Stepdown and 1/2 tool diameter Stepover and 0.025 mm per flute for cut and 5 mm SD, 0.1 mm stepover 0.015 mm per flute and max revs for finishes. By going so small on Stepdown the tool is working hard to start cutting the chip, so is skipping one cut just rubbing and next one bite too much wich results in cutter towable.

A 3 flute vari-mill would also greatly help out your rigidity issue by breaking up the harmonics. Might be able to cut conventional with a vari then.

Thanks Tom, any specific types/brand you would recommend?

[@tomoster2840]

Harvey Tool, YG-1, Widia, many others, or even custom endmill for $20-40 per tool. An endmill with a higher helix angle around 45°~55° might also help reduce side-cutting deflection by redirecting the cutting forces.

[@TechStreamline]

great videos. I bought a 6040Z and was very disappointed. I could not do anything in aluminum. I found everything very complex, from drawing to machining. I put the sale and so far I have not found a buyer. I preferred going to Laser that will suit me better. I see that I was using the wrong bits. although my greatest need is to make markings and not cuts. What bit to do engrave do you recommend? Congrats on the videos

[@raulalvarado6886]

Where can I get one of these machines??

[@justin_704]

you are probably breaking a lot of endmills due to chip build up and lack of flood coolant. aluminum builds up as a gummy residue on the cutter. reduce this and increase tool life with constant coolant. Also choke up on the tool length to give more stability on the tool. If you can get a tool with a thicker shank not just a 1/8". That spindle looks like it can handle a larger tool holder so give it that and get your tool tip to be just the size you need. By increasing the rigidity in your tool and holding you will be able to get more aggressive cuts and faster times.

[@alexisolivan7712]

Thank you for this video, I have the same machine as you, when I use your settings, when the fall of the End Mills in the matter, I broke every time ... Do you know why? Thank you

[@MBcreates]

That’s hard to tell. Can you share a video of your attempts? Important is to use a helical path when you go engage the material in the z direction. This the most risk full part of most cuts because in general end mills don’t like cutting in the z direction that much (that why why we use drill bits). You have to go really slow on this part of the operation. I keep 40-50 percent of the normal feed rate as rule of thumb. You can see it in the video on 4:52

[@therealstubot]

I've found the same thing on my 6040. A larger tool ( 6-6.5mm ) requires more rigidity than my router has. I get better results from 3-4mm tools in aluminum. My 6040 is crazy strong in X and comically floppy in Y. I try to arrange my heavy cuts to be along X where possible. Even cutting wood along Y is chattery. I'm thinking that I need to install larger guide rods in the gantry to get a more rigid Y axis. For aluminum, I always keep a good air blast on the tool, and a little kerosene or WD40 dabbed on with a brush. I seem to get way better wall finish with climb milling over conventional. My workhorse aluminum bit is a kyocera 1/8th inch carbide 2 flute from ebay. They have a white collar. They're short though, but very stout and sharp. When I need some depth, I have some 1/8th inch cobra carbide bits that are long. They cut very nicely but break easily. I have some very cheap ebay 3mm 3 flute HSS bits that work ok, but go dull faster than they should.

[@MBcreates]

Hi Jeff, Thanks for your sharing the tools you use. I will certainly check them out. The difference in X and Y axis strength is something I experience too. I’ve noticed that many CNC 6040 users are having a different opinion about what the X and Y axis is. For me the longest side of the machine (the 60cm travel) is the Y-axis, and shortest side (the 40cm travel) the X-axis. Do you agree of do you have them the labeled opposite way? I’ve searched for info on this subject but couldn't find anything useful.

[@therealstubot]

@@MBcreates Hi, yes, I concur with you. Y is the long axis, while X is across. I guess it wouldn't really matter, unless you were sharing CAM files, and the parts you were making were sized such they would only fit one way. I also generally set my origin to the center of the part, and many of the parts I make are square or circular, so most of the time, X and Y don't matter to me, unless I have to cut a slot in aluminum. Then I have to be conscious of the axis or I'll certainly get horrible surface finish at best or snap a bit at worst. Love your content, thanks representing the 6040 community.

[@MBcreates]

Yeah it’s only annoying when talking talking to other people, you never know for sure if your talking about the same axis. Maybe we as community have to set a standard XD

[@Unix_Based]

Jeff Stewart: Try replacing the whacky guide rods with a heavy duty extrusion aluminium profile and two linear rails on it. Sure, a lot of parts has to be modified in order to make everything fit. But the people who had done it, are happy they did. i.warosu.org/data/diy/img/0006/70/1405832153529.png There are nuts and bolts available to fasten linear rails on them.

[@therealstubot]

@@Unix_Based Hi, thanks for the suggestion. I will likely just take it all apart, figure out the biggest rod I can fit, and mod the gantry to fit them. It looks like the current guide rods are about 12mm or half inch. Going to 16mm or 5/8 in. would be a doubling in stiffness. I'll use hardened, ground drill rod, and machine the guide bushings from oilite or SAE660 bronze. I have a lathe and mill, so this work would be easy for me. Just have to find a time when I don't have a month of project backlog to do.

[@WorldLaughsWithYou]

Any reason you're milling conventional versus climb?

[@MBcreates]

Yes, Because of the unsupported X and Y rails the machine isn’t really sturdy. The climb cut results in a really shaky and unstable cut. The conventional strategy performance much better.

[@jamescatlett9596]

Any reason you're conventional milling instead of climb milling? This alone would help surface finish a lot.
