I swapped my threading tool out to chamfter the end of my threads some more, but then when I put the threading tool back on to clean up the threads it started cross threading my shit.

I want variety so i can test the differences different flute counts and diameters make on my machine.
Also don't you fucking think i looked up the speeds and feeds already? All guides are fucking useless to me, they are for normal CNC machines, not for small routers used as cncs.
Every speed and feed calculator i tried gives me unusable results, like lowering RPM too much which i can't do because i will lose torque, or increasing feedrate to match the RPM which i also cannot do because my machine can't move that fast, or increasing the dept of cut.. also for shit, i can't because the steppers will just miss steps or get flat out stuck in the stock, i can barely handle 0.3mm DOC, so when the new endmills arrive i will try 0.2mm DOC, at 200mm/min and 12k RPM (rpms are fixed and i cannot change them too much or i will lose torque)
Basically, advice from experienced machinists are useless for my case because none of them have experiences with ghetto machining, which is a completely separate planet from commercial man sized machine CNC machining

>> No.1780969

>>1780964
There's no "variety for testing", a 3 and 4 flute endmill will be worse, invariably, it's completely pointless to buy them. Obviously you completely fucked up when trying to get speeds and feeds calculated because of the terrible results you're getting. Here's the super-retard-version of setting up your machine:
More flutes = MORE FEED, more torque
Bigger endmill = LESS RPM, more torque, with some exceptions at very small sizes
Higher RPM = HIGHER FEED
Bigger endmill = HIGHER FEED, and conversely,
smaller endmill = LOWER FEED
HSS endmill = LESS RPM and LESS FEED, carbide endmill = MORE RPM and MORE FEED
High feed loads the steppers too much = DECREASE DOC
High feed loads the spindle too much = DECREASE ENDMILL SIZE
>>THEREFORE
use SMALLER ENDMILL with HIGH FEEDRATE =RELATIVE= TO THE ENDMILL SIZE with LOW DOC, you can't just take your calculated feed for a 4mm endmill and swap it for a 2mm and see what happens, this is why you kept breaking shit. When people tell you that your feed is too low, it's all relative to the endmill size. Every 1 flute multiplies the feed you should be running, so for you the ideal would be a 1-flute, but a 2-flute would probably still work.
You can't change your RPM? Change the size of the endmill. When the endmill is changed, the feed is changed. Steppers can't take the feed? Reduce DoC. Doesn't matter if you're only doing 0.05mm per pass, you MUST keep the feed right.
And last and least, with a 2-flute 3mm carbide endmill in aluminium at 14k RPM you want about 350mm/min FOR SLOTTING, if you're not slotting, you need less engagement and more feed. The 2mm 2-flute carbide endmill would be around 150mm/min, the 4mm 2-flute carbide at 1300mm/min. There's an android app called FSWizard, you can use it to calculate shit for yourself.
If it still doesn't work, either you're beyond retarded or your machine just can't do aluminium.

so i tried to download the calculator and fill out the parameters for the one end mill i have left, to the best of my limited knowledge and it is telling me that for a 2mm dia 3 flute non coated carbide flat end mill and 0.2mm DOC, 12k RPM i need the feedrate to be 876mm/min for alu, does that seem correct?
but it seems like my best bet is to basically use 1mm dia, 2 flute mills because that way i can go really slow at 270mm/min which my machine could actually handle no problem at 0.2mm DOC

>>1780978
fuck.. this is all i have left, and i am kind of scared of trying it, because if i snap my last 1mm, it's game over until the new batch i ordered arrives in two months, since according to the calculator with the 3mm mill i would have to feed at 1100mm/min which would mean a DOC so incredibly low i would basically have to use probe leveling like i do for PCBs
And i doubt those 0.5mm dia mills could handle alu at all so those are probably out of the question

Are these even actual metal-cutting endmills or pcb endmills? Do they have the same geometry as the ones you're ordering?
That aside, I wouldn't recommend trying with the 1mm bit, the machine probably doesn't have such tight tolerances that it could run without breaking it.
I'm getting 690mm/min feed for those settings at 2mm, make sure you have slotting checked.
>shallow DOC
You're making repeated passes either way, it doesn't matter that some cuts will have partial engagement because the surface isn't perfectly leveled. What's important is to fix the aluminium to the base well, so that it doesn't freely flex, because flexing could cause your DoC to jump from 0.05 to 0.2 and then fuck up the job. Especially likely to happen in the last few layers.

This is a good thread to ask, navyfag here, I was turning in calibration equipment yesterday, and one of the electricians handed me what looked like a mechanical surface profile gage, but the movement was lateral, not up/down, and read in grams.
I looked all over MCMS for previously deleted equipment(since it wasn't on our list) and no one had ever used it. Any idea what it could have been? Either way I'm sure it was a machinist tool that ended up under the electrician workcenter somehow.

update:
In the olden days machines needed batteries to keep parameters. This machine had a switch, so when you were done with your shift, you flipped it to top off the battery at night.

With the retrofit that had an eeprom for the parameters, this switch lost its function. Some genius had the brilliant idea to use this switch to enable the controller signals to the machine.
Now that i figured out this fuckery, the controller is sort of controlling the machine. But only when i keep pressing the enable (whatever the button is called to clear the e-stop) button that should be pressed once. Spindle and oil pump is working. Servos are not moving but the controller is sending motion signals because the display position changes. If i move too much the controller gives servo error and stops, maybe because no response from the servo amp.

Im guessing some contactor is not latching to keep stuff enabled.

If there are encoders on the servos, backlash is compensated in software?

You're going to be troubleshooting every kind of CNC for a very long time. I haven't personally used one of these super duper low-end CNCs, but my guess is that you're going to run into a speed issue very quickly. The "spindle" motor on it is really small, and it's completely impossible and a waste of money to upgrade to a half-decent cheapo spindle later on since the machine has such a small size. Either way, the spindle is small and needs a very high RPM to deliver any power whatsoever, so if you follow that post I linked, it means that you will need to use a very small endmill. With a very small endmill, jobs will take extremely long, and with these cheapo (here I mean everything under $10k) CNCs you absolutely have to babysit it, it's not like a 3D printer that you can just leave running to do its own thing. Basically this machine is good for exactly what the preview pictures show, small engravings in wood and plastic.
The next tier above is still going to be total ass, but with ballscrews and a cheap 500W-ish spindle you'll be able to use 4-6mm endmills and a decent depth of cut so you will be able to get parts done fairly quickly. These CNCs probably cost around $500-$800 direct from China. You could also build one yourself if you have some bare minimum tools or know someone with tools, then the cost would be reduced to around $300, but it's not at all easy to be designing a CNC around your limitations without knowing what you actually need in a CNC. There are some existing designs like the MPCNC which actually machine aluminium pretty well, if you have access to a 3D printer that could be an option.
Also you will probably end up wanting to buy a compressor if you don't already have one, take that into account.

Well if you already have it, just try using it, maybe it won't make evacuation that terrible. It depends on the shape of what you're milling, but your shit is narrow deep holes, aka the worst situation.

use two offsets, make the first 2d contour slot halfway down offset from the actual edge 0.020" or so, clean up halfway down at the actual size, then the next passes will have some room for chip evac going down all the way.

Really you should have an air blast at least though. And yes WD-40 should prevent chip weld.

YES I DID IT!

i finally made that stupid fucking carabiner!

WD40 is literally THE SHIT

When i started cutting i heard chatter and the usual shit, and started to mentally steel myself for another broken endmill, but as soon as i sprayed some of this liquid gold in, it's as if the god himself came down from heaven and came on my endmill

there were absolutely no chips getting stuck to the end mill, the cutting was so incredibly quiet in fact that when i turned my hand held vacuum on the spindle could not be heard at all

And look at this chipload, those chips are fucking MASSIVE i never ever got chips this large before

i was also cutting 700mm/min with 0.1mm DOC at 8000 RPM and the spindle or the steppers had no issue whatsoever with keeping up the feedrate

I am so fucking happy right now, holy shit, i can't believe nobody here recommended me the wd40 and i found it by complete chance when reading tutorials

I assume the it is powered through a separate mains cable, hence the R S T E terminals.

Id pop off the hood and see where the cabling goes.
I dont think theres too much brain in either of the machines so the cabling should eventually end up in a relay/contactor or a sensor. From there its easier to figure out what each cable does and where it should go in the main machine. If it goes to there at all.

>The wires leaving the terminals to the right (24NC, 0CAL, 50, ...) go to harness or inside the machine?

Inside the machine, I don't have the "operate" light lighting up but a fan kicks on when the hydraulics start moving through it. Heck maybe it only shows "operate" when it's cooling down the hydraulic fluid too.

I just kind of figured the wiring conduit with the 4 bundles of wires coming out of the bakc of the machine, and a special plug for the back of the chiller there, all the wires should be wired in there.

I hope it won't damage it if I plug the remaining ones into M1 and M2?

This is a machine shop. If you're actually serious about producing parts at a worthwhile quantity, 3D printing is a borderline retarded option because a machine shop is going to have 90%+ of the equipment necessary to produce injection molds. The only thing they wouldn't already have is the injection molding machine itself, and possibly someone who can design the molds in the first place, I suppose.

>...b-but those machines are expensive...

Used ones aren't too hard on the wallet, and they can easily shit out parts 2 orders of magnitude faster than a 3D printer can. Never even mind potential issues stemming from the porosity of printed parts, cost of the printed parts, or the amount of babysitting the printers are going to need.

I want to get a small mill to learn on, do small projects. I say small because I have no room in my garage, and will need to get it into my basement.

My assumption is, if I get something bigger than the infamous harbor freight mini mill, it's going to be too heavy for me to get it down the steps in one piece.

Real milling machines are heavy motherfuckers. Rigidity, and therefore usefulness, is a function of mass and bulk.

>Am I just shooting myself in the foot by planning on disassembling a better mill and ferrying it down piece be piece? If I do that no individual part should be over 150lbs, right?

I actually scrapped a mill (a Lagun) a while ago, and weighed the pieces as I loaded them up. If I remember the approximate weights correctly...

The ram weighed 230lbs.
The base weighed 400lbs.
The knee weighed 350lbs.

I still have the table, I'd hazard it's a little over 250lbs, but I haven't weighed it. The head assembly I also kept for parts and is the second-lightest assembly. It's somewhere north of 100lbs. The lightest bit is the saddle, which is maybe 50-ish lbs.

The body was the heaviest part, but I don't know by how much because I cut it up and kept it. I know it was easily 500lbs, though.

Keep in mind, I'm sure I'm missing something and/or underestimating, because the total weight, even adding some on top for all the smaller bits, doesn't make up the 2500lbs+ of the assembled machine's weight. Either way, there are plenty of parts on a full-sized mill that are too heavy to wrangle by yourself.

You're going to be stuck with one of the weird, mid-size "benchtop" mills if you want something movable, even disassembled, by hand.

Beginner here. I've got a line on an old South Bend lathe for sale. Its an American mode model. The seller has posted some garbo pictures so I can't make out the model but it appears to be in decent shape and is a good size. They don't know what they have as the listing uses the wrong name and said it is a wood lathe so I might be able to snatch it up for only a couple hundred bucks. I currently have a 36 inch Atlas I picked up cheap but it was a bottom of the line model and doesn't even have a leadscrew. Problem is, I am looking at a 4-hour drive to pick up the SB lathe and I really don't know much about them. Are they better than what I have?

>> No.1787566

>>1787537
Not him but I'll put in my two cents. Depends how much work they need and how hard parts are to get. We have an old HAAS VF2 at work I've had to fix a few times. Most things on it are off shelf components that are still made so it's not too bad if you can find a model number that isn't for HAAS itself. For how they compare, again depends on the machine. They're usually slower and don't do well with modern toolpaths or 3D surfacing because the controllers can't keep up with the code. They also might not have certain codes or features that are standard now.

A tool rep I work with a lot turned me on to insize metrology tools. Then one day he brought over a small set of dial calipers and a digital micrometer and an indicator and had me compare them to a Mit and a Starret. I was very impressed. Apparently they have done contract work for Mit before and are basically the same just differently branded. I've bought 0-4 mics, 8" dial calipers,. 0005 dial test indicator and a few other odds and ends from them (not even from this tool rep mind you usually just buy cutting tools and holders from this guy) and have absolutely zero complaints or doubts about their quality. The dial calipers work better than a set of brand new starters a colleague recently bought. Around a third the price of Mits and starters. Sell everything from scales to CMMs. Check email out.
