I’m thinking of getting into the business of selling O% receivers. My idea is to provide them in the 4 most common end configurations - left hand, right hand, and for receivers that will have buffer tube threads on either end. To stay out of trouble with California, each block would come with clear instructions; “How to use your new door stop.”
I have a friend who retired at 55 and moved to Henderson NV so he could fly his planes year round. He has a CNC machine in one of his hangers and mills plane parts and AR-15 and AR-10 lowers. I have one that he milled for an AR-15. 😁
I’m in the same boat I wanna do this but I have no idea what is adequate for this kind of work. I’ll be doing this in my garage and space is a factor for me as well sucks
HSM tip if I may: increase the stay-down linking to something like 8 inches, increase the non-engagement feedrate to the max the machine will do (400 IIRC on that guy, right?), and set the stay-down at 80%. It helps a ton. Even keeping it in "Always Use High Feed" makes the machine go from cutting to non-engagement much more quickly without going from G1 to G0 all the time. YMMV of course, but this is what I've found on our VF-6SS.
I like to leave that option off the first time I run, just to make sure my tool doesn't run through anything it's not supposed to. Then once I'm in production, I'll let her eat. I haven't ever had a problem, and I'm probably over cautious, but I would rather be safe.
Another tip for production: use the Parametric Feed in the post processor. Super easy to fine tune after you've realized you can feed at 130% on one path but not on the next. Way better than the barely-functional Haas in-program version. So how much you charging for the .SLDPRT? ;-)
+Venom Defense Basically the post outputs all the feedrates used in the toolpath as a variable. Doesn't for drill operations but any milling op it does. I find it very handy if I don't want to go back to my office to change a feed in an adaptive toolpath with tons of non-engagement moves.
This video right here is why gun control doesn't do shit fighting gun crime. Even if you were to ban all guns, cartels can easily afford the 10-20k for a decent cnc machines to just simply make their own gun factory.
@@MM_45 no you fucking retard. They have those in mexico because they have traffickers that can purchase them legally and bring them over the border. Same way everyone in cali and chicago get them.
God I love this. Way way to expensive a hobby. But programming and machining in general is awesome. I wanted to get into it when I was young. But no one would give me a chance. I like guns. So I guess that would be fun. But programming one to make anything you wanted. Sorry long comment I know. I just find it amazing. Almost magic
The lower receiver plays a very very small part in the accuracy of the finished weapon. Hell, the handguard effects the accuracy more than the lower. Upper, barrel, and type/size of the round/load play the biggest part.
I have a bore cut into my center vise jaw. I use it for XYZ 0 for anything one that vise. I cut the jaws to the same zero point as the part. perfect alignment every time.
if you custom machine a set of soft jaws in the same profile as the part you could actually touch off on a reference face point (on the stationary jaw) and mark it into mastercam, gibbs or any other program you happen to be using as your X,Y,Z point of reference. that would allow you to flip the part and tap it into place and go to town. mind you I don't know if I should actually be giving out alot of information on machining to any one since it is trade secrets
I've been going down a rabbit hole researching desktop CNC machines, and the buffer tube threads has been my biggest question. Cannot figure out how this is done. My only guess so far is that the receiver is flipped vertically and an interior thread is cut
What happened with venom defense? I'm pretty sure i ordered something from them either a upper and lower or maybe just a lower? I don't remember but they wouldn't respond to emails for the longest time i figured they got shut down or something 😢
Looking good! Are you using the HSM setting on your machine? I've got to put up a couple of videos of the TM1P ripping through some blocks of titanium and aluminum. Fun times!
Yes, but just in the trial mode at the moment. I haven't ponied up and handed over a pile of cash just yet. It's amazing how much difference turning it on makes.
I'm trying to build a DIY CNC machine that would be capable of milling 7075 aluminum. I'm not worried about speed of production, but I'm having trouble determining how powerful of a spindle I'll need as well as what the minimum spindle speed (RPM) requirement would be for this purpose. I understand the speed of lateral and vertical movement can be brought down to 20 mm per minute or less if needed, and the step down can also be brought down to a minimum. The only videos I'm finding where they are milling 7075 aluminum seem to have the RPM set at about 18,000 rpm. If that's a requirement, that greatly reduces the options when it comes to spindles. Can you help?
What type of cnc mill would you recommend for someone just getting into the industry and looking to make parts for themselves along with custom parts for the market?
yes, just slower, but tbh there arent many decent machines less than a used tm1. if you get lucky you could find a fadal thats not completely worn out, but the footprint is pretty big, even on the 2216.
@@sebastiancamarena2824 Jim McPherson here on YT milled an AR lower from titanium on a DIY CNC converted Sieg X3(Grizzly G0463). All in for the mill, conversion parts, steppers and controllers the machine can be set up well under $10K with some basic tooling. It won't be as precise, or handle production volume work like the Haas in this video, but for a hobbyist or prototyping it's entirely possible.
it'll make the part just fine - it's just going to take 5x as long and it won't be as pretty. The Haas also comes out perfectly on size with little to no effort, whereas my tormach always required re running key features to get them sized in.
Thanks for the reply. I was thinking that it wouldnt be as fast alright. The tormach is a great stepping stone/learning tool without forking out big money. keep up the vids ... I love em !
+gunhappyie Absolutely. I wish I still had mine for doing prototype and development work. It worked very well for that type of thing. They just aren't designed for production, not that that is any secret. I outgrew it much faster than I anticipated, which I actually view as a testament to how well it worked.
Id love a tormach but after shipping to europe and taxes it comes out crazy money. While its not as well supported (at least not in english) I might go for the optimum line of machines.
i my self would either stick to something that uses a fanuc or haas controller! you can grab posts for master cam to run dam near any unit, but autodesk runs a student copy for 5 years for free and after dumping upwards of $90,000 cad on a good production unit it might be the cheapest way to go
Very good ! Thanks for the quick response! I also work with adoptive strategies at HAAS TM-2P only other CAM are many times umenishayut processing time! Subscribe and Like!
i would have ran a 3/4" 3 flute to rough the part out then came back with the 3/8" to clean the surface. would save a fair bit of time if your doing a mass production... 6 steps just to get to 80% is close to 1.5 hours at $130/h not alot left after for profit
For someone that builds AR’s I’m pretty clueless on how to mill a 0% billet. Can anyone please tell me what exact CNC machine do you need to do the process. Do you just get a CNC machine and download a program or am I wrong.
Thats a hard question to answer but ill give it a try you will need a CNC machine there is no exact machine eg Tormach 770 or 1100 will do it as would a Haas V2 or even a home built CNC machine as CNC is a tool just the same as if you used a file and a grinder to make a part. The program is called CAD or Computer-aided design (basicaly you make the part on a computer just as you would back in the day with a pencil and paper) when you have that part you use a second program called CAM or computer-aided manufacturing to deside how you are going to cut the part out of your stock. When done the CAM will make whats called Gcode that is simular to how you would write out a Recipe for cooking a cake. That Gcode is generaly saved to a thumbdrive and pluged into your CNC machine which tells the machine how to do what you would like done. so to recap you CAD design the part on the computer or down load a model allready done CAM deside how you are going to cut that part give the Code from the CAM to the CNC machine machine cuts the part just like this video Hope this has been helpfull
Wilkoslavakia-Thanks for explaing this to me I've been pretty confused about milling a 0% billet for a while. I understand it a lot better now that I read your reply.
I could see about 10 different z moves that didn’t need to be there........I’m guessing fusion360. Might want to clean up the process you could knock at least 5 min of the run time......
Lol Was thinking same thing. Just go to last tab and use "Keep Tool Down" and set it to about 3 inches and it would have eliminated most of those. Also should have done a full DOC from the get go. If my Tormach 1100M can do a full DOC with 0.100 WOC then this HAAS should....
Hello, if anyone has the g-code for this drawing and wants to sell it, I hope they write to me. I actually had the g-code in the past, but I lost it. Thank you
Why so slow? Never gonna turn a profit with 20 minutes just for the A setup, especially when you still have at least 3 more after this one unless you have multi axis, in which case idk why you wouldnt already be using it.
that's how they are advertised and that's probably how he bought it. Kind of Dumb, but then again, it's the specific type and size of aluminum for making lowers. 🤷♂️
???? the color you see is the cutting fluid! a water based liquid either manufactured by valcool, castrol or any number of coolant/ cutting fluid manufactures!
