You can add capacity to your compressor by adding an extra tank, best an empty stainless steel butane gas tank. Add a Tpiece to the outlet of your compressor motor where it enters the original tank, that way it will fill up both tanks and give you more volume of air. For a vice lookout for a surface grinder vice most are fairly low profile.

Iscrapped my air compressor and switched to a small reciprocating air pump. Its about 6 inches cube and nice and quiet, and pumps a serious blast of air onto the cutting tool. I actuallly have dual nozzles at 90 degrees to really clear out those cut grooves. The recip pump needs nomtank and only comes on when you need it (when my spindle is running). Cost about $100 USD from memory.

@ericblenner-hassett3945 2 года назад

I have seen an addition to add more air and it may be a bit risky for a beginner to do. It is adding a portable air tank after the compressor and before where the air will be used. One of my brothers and I were stuck with a flat tire and had a portable air tank and a car tire air pump. He had an impact wrench, just not spanners to remove the wheel to put on the spare. The short version was fill the tank, use the impact to take one lugnut off, repeat for almost 2 hours. In this case, you might want to add a one way valve to have the portable tank act like a secondary reservoir and possibly a T connector so you only use one location on the tank, making it possible to follow RU-vid videos on how to use a propane tank as a portable air tank. Thank you for such simple and concise information that, as you pointed out, is easily overlooked.

@Dbone3211 3 года назад

As a trade mechinist I agree with many of the points in this video, the only thing I want to say is when it comes to taps invest in spiral flute taps instead of strait flute. The spiral flute brings the chips up out of the cut, they are therefore far less likely to brake in your hole

@ThisDesignedThat 3 года назад

Thanks for the tip

@sparkplug1018 2 года назад

I am never going back to straight flute taps after using those spiral flute taps, cut so much better. Also adding a chamfer to the hole before tapping is always a good idea, plus looks nice.

@laurencestonard4593 2 года назад

Thanks for putting that video together, lots of good points. The mag base is good, just clamp a steel parallel ( or block of steel) on to the table , may be a 1,2,3 block ( 25, 50 75mm) I bought a vertical band saw can cut metal and wood. Please clamp your metal vice down, fix it to a block of ply or steel and then use a G clamp(s) when you want to use it. Well done with the safety tips, your compressor will have a blow off valve so if the working pressure is 100 psi it will go off at 115psi, should have a check every now and then, we do it every year, visual inspection and change the oil, drain the tank every month to get out the condensation. Well done and good luck

@mbanb6775 Месяц назад

1 or 2 flute end mills are fine for aluminum. Coating is important though! You want TiSiN, TiCN, ZrN or uncoated endmills. You DON'T want an end mill with any coating containing Al (aluminum) as that will increase the tendency for chip welding to the milling bit.

@sparkplug1018 2 года назад

Most people see the cost of the machine and figure, that's the big expense right there. But yeah, your money is going to be in the tooling and measuring tools. But even if you're just starting out, look for deals on used Mitutoyo and Starrett, high quality precision tools made in Japan and the US that last a lifetime. A lot of my measuring tools were given to me by my grandfather after decades of use in a machine shop, and they are still in good shape and accurate. Another tool to invest in is a chamfer bit, its good practice to always chamfer the hole before you tap it. Makes starting the tap straight much easier and makes threading a bolt into the tapped hole much easier. Plus it just looks nicer, more finished and professional.

@ThisDesignedThat Год назад

Great idea, ill add that to my video list

@phantomhck 2 года назад

Nice video, thanks. For beginners I would highly recommend studying more on material speeds and speed and feed rates, chip loading and cutter geometry. Aluminum galling (gumming up) can be due to spindle speed being too high or the chip load too small. Aluminum is forgiving but stainless is not. In some cases, machining slow is not an option if the spindle or motors can't keep up.

@ogretowman8695 3 года назад

Look for an auxiliary tank and hook it up to the out flow port . You can easily double or triple your total volume . You can also put the compressor away from your work area . I'm in the States and have been running one compressor or another for the last 20 plus years , pressure is always 150psi or better and even have a small 4500psi unit . Never had a compressor blow up , have burned out motors and pumps but that's about the worst ! Good luck and thanks for the insight , because I'm leaning towards getting small cnc machine . Thank you

@ThisDesignedThat 3 года назад

Yes I saw John do this on his early NYCNC videos. At the moment I dont do long cutting jobs on this machine to the compressor does what I need for now but I'll think about this upgrade in the future.

@InformatrIIcks 4 года назад

About endmills, i've always heard to not cheap out on them. You might be breaking a lot of endmills because they are cheap and so not as tough ... But i guess if you're a total begginer it might be interesting, i'm talking "i don't have a clue what speed and feed means". An other positive aspect of good endmills is that they'll come with documentation that can be trusted, which can ease the dialing of speed and feeds

@ThisDesignedThat 4 года назад

Yes I do partly agree with the first part but Ive broken many endmills purely from the crappy electronics in this cnc. So many times it just cuts out while cutting (with the ncpod not detected mach3 error) also just silly things like moving the spindle and crashing into the workpiece when trying to set zero point. i'd be so pissed if i snapped a £40 endmill from a silly mistake like that

@arbjful 9 месяцев назад

Really great information you have presented here. Thanks for posting. What do think about painters tape and super glue technique? Also is there any advantage in using a larger collet? My machine uses ER-11 , do you think upgrading to er-20 would be better for aluminum?

@ThisDesignedThat 9 месяцев назад

Painters tape works great but I have found for long operations and when I am using coolant I have had the tape come off the metal. When Im using coolant I like to use Mitee Bite workholding wax as it is waterproof and great for holding thin stock. Larger collet size can be helpful to get access to bigger and more advanced end mills (indexable etc) you need to make sure your machine can handle the bigger size endmills though. I would love to have an ATC spindle above all else, I would love to have auto toolchanger on my CNC, in the future I plan on making this upgrade

@rbondy008 3 года назад

Just starting out so this was helpful. Just a couple of questions. How do you collect and dispose of the coolant. Is it because it's mist maybe there isn't as much as I'm thinking?

@ThisDesignedThat 3 года назад

Yes there isnt much left over when using mist coolant, just a wipe with a cloth is enough. I also sometimes just lay some kitchen towel next to the work piece to soak up any coolant incase im using a lot of coolant or trying to tweak my flow rate. Worst case scenario is it will just drip through the T Slot bed and onto my plywood enclosure base, again you can just wipe this so theres not much to worry about.

The amount is controlled by the valves on the coolant. Its spraying a small amount of coolant, most of the coolant is just going on the work piece and end mill and then evaporating. When I'm using a lot of coolant it just pours down into the tslot bed where I wipe it up after the operation.

I know carbon fiber is a bit stiffer than aluminum and retains heat much more, thus i will need to make sure it doesn't heat to the point it de-laminates.

Had a friend's air compressor tank rust out due to many years of leaving water in the tank. Just ending up rusting through and leaking air faster than it could fill up. That is probably what happens to most of them when they rust out. Only a very few of they would have any danger, and it takes many years of abuse to get there.

Thats reassuring to know, Im a bit of a worrier so I knew it would always be in the back of my mind when using it so I just wanted to be safe.

Is it practical to have 100mph+ blowers push the material into the back of the enclosure that has a gap dropping into some sort of collection container?

@ThisDesignedThat 2 года назад

That's a great idea and it could work if you only have big chips to blow but if cutting aluminum on a hobby cnc machine then you will have chips that resemble more of a fine shaving and therefore very easily airborne. So a blower might move some into the collection container but also blow it into the air and get everywhere including all over yourself

@obe22099 2 года назад

@@ThisDesignedThat I forgot to add a important part of the design. The entire thing would be inside an enclosure. I made a rather large air tight enclosure for 3d printing. Besides the toxic vaporized plastic being vented out it's also temperature and humidity controlled. ABS or Carbon Fiber laced Nylon filaments have a high ambient temperature requirement and absorb moisture quickly preventing layers adhesion. I've been looking for videos with something similar but it's not something that seems important to people with plasma cutting/mills/lathe/router equipment. Probably because most are large scale and already inside well equipped working environments.

don't go too cheap on the digital Vernier I got some off ebay and the inner diameter gague didn't even line up : ( only good for outer diameter readings, and it's pretty iffy on those too but I STILL use it for everything because of how essential the tool is

If you use the CNC a lot, dont use acryl or plexiglass for the front windows, they become "sandblasted" and get scratches very quick, use safety glass instead (like a car windshield, glass-foil-glass), its easier to keep clean and hold for decades, as long as you dont smash snapped "big" drills/mills into it. The mist cooler, the main coolant is the air, the main job of the liquid is lubrication, so the mill dont clog up. To use the liquid as coolant you have literally to flood the mill with it. If you have something you dont want or cant use oil, you can also use a vortex tube, it dont have lubrication, but really cold air.

@ThisDesignedThat 3 года назад

I am slowly discovering this, every month or so i'll wipe the windows as they have tiny shavings of metal and Im noticing small scratches. I do feel safer peering into the machine when its cutting though knowing I have a layer of polycarbonate between me and the machine. I guess safety glass wont shatter and is strong enough to withstand impact right?? I might think about swapping the 2 front window panes with glass in a few years if the scratches build up to a point where it impacts the video recordings. Thanks for the info on coolant, Im going to upgrade the mist coolant this year hopefully with something like a fogbuster/MQL setup

@wolf310ii 3 года назад

@@ThisDesignedThat If a 20mm mill snaps at 20.000 RPM it could shatter or crack the glass, partially, but the foil holds everything in place, so nothing flys around. Small mills may leave a little sratch (like when a little stone hits the windshield in a car on a highway) or nothing at all. It depends on the energy of the impact. On industrial CNC mills there are usually large thin (around 8mm) glass windows, only hold by a rubber seal in the frame. As long as you dont rip a 40kg vise from the table, they hold everything inside. CNC lathes on the other hand, have usually small thick windows with serval layers of glass, transparent rubber and polycarbonat in a steel frame, 20-30mm thick screwed to the door. Sometimes they have even grates in front of the window, because of the much higher energy they have to deal with, if a chunk goes fly, wich leaves a big dent in the door and can even lift the door out of the slide rails. To prevent scratches from cleaning, clean the windows as soon as you finish the work, first with compressed air, to remove the chips and then with a clean paper towel. If you wait a month, the water in the liquid drys and a sticky oil layer stays

Some of those engraving bits can be modified for thicker lines. I basically just make a new tool profile, and fix up the broken tip to suit the profile..

@ThisDesignedThat 3 года назад

Interesting, would you just use a bench grinder or something to make the new profile?

@DistantVision85 3 года назад

@@ThisDesignedThat Well, with the really pointy engraving bits, if the tip snaps, just clean the tip up. It is now a flat bottom engraving bit. The profile I mention is just the setup for tool selection in my design software

When your vise raises the part, why don't you just (re)calibrate it?

@ThisDesignedThat 3 года назад

It raises it on one side only, so the part is tilted so you cant re calibrate

@@ThisDesignedThat But you can mill a slot in the sides of the vice and then put a guide in it. Maybe use a dovetail slot. Alternatively mill 2 dovetail slots in the bottom surface and add dovetails to the bottom of the jaws so they always track ?
