It’s so awesome to show everyone all the little tricks I’ve learned over the years! There’s plenty more to come so make sure you subscribe so you don’t miss any!
I've done a lot of these and I always make a fixture and have the drill bushing ground flat against the hexagon so when the drill goes through it is supported from beginning to the end. It is very accurate and clean. The drill hole is also lubricated from beginning to the end. Nice technique. I work alot with fixtures and precision ground bushings. It is extra work but worth every dollar.
Love the video! More ESPRIT!!! I think I'm getting a GT32 as well. Can you do a video on the machine layout please? I need live tooling facing the X axis on path 2, and B axis on path 1 and 2 Thanks Donnie! You are the man
I love the GOdrill series from kennametal. I run a production in titanium grade 5 in which i use a 3.5mm 5xD drill. Last time i changed it, it had made 20.000 holes. The holes are 12.5mm deep so that adds up to 250 meters of drilling. And the drill is stationary. Thats impressive for an all-round drill 😊
I love these videos. I only run a manual lathe and mill for the occasional one-off part. These little tips still come in really handy. Thanks for sharing the knowledge fellas.
Hey, really like the way that you edited the simulation to be the same perspective that was being shown in the machine. It really "ties" everything together, just like those wire holes.
we build those and use flat bottom drills to pre drill but cut hex first, this is by far the best approach as we’re constantly breaking drills & emills
Thank you again for the awesome video. I will be honest I'm just a home tinkerer with lowly home built CNCs but it is so awesome to see stuff like this and the processes behind it!
i'm working on nearly same parts from a week now, and i had the same idea than you at first.. But my superiors tells me to drill the holes after hexagon (i'm a little frustated).. I'm so glad to see i has a good idea at first !!! thanks ^^ (and thanks also for the "deburring trick", i think i will modified my program next monday ;D )
Donnie, great job explaining the wire hole. Having never seen bolts with wire holes personnelly, I am curious as to whether there is just the one hole or two in a bolt like that?
Would like to see some trocoidal turning of a hex. The old in and out on the cross slide. Instead of polygonal or milling hex. I have an excel program to do it.
I'm a data engineer, not a mechanical engineer, but I find the parallels between our two fields interesting when it comes to thinking through optimal, repeatable processes.
Little tricks with big happenings, I've been watching your content for a while now so ... ya ... love your content bro ... actually like it , technically im an electrical and electronics engineer with an embedded systems specialisation, so tell me are u guys in California? ... im in India right now ... so ... is there a part time thing for masters students like me ? ... or are the positions filled up ? ... anyways really respect your hard work and quick fix thinking ... looking forward to working with u guys someday ! ...
i think i forgot commenting this on the flat-bottom drill video if i have weird holes, i tend to do 2 roughing stages with drilling between them with the surfaces from roughing 1 being flat towards the holes as shown here. it generally pays off in how fast you can drill and how long the tool lasts, even if the program takes a bit more time.
You mention tool wear. Can you guys talk about how you track and measure tool wear and breakage? I know the functions in my tools to do it. I just don't have a refined process for doing it Like, how often do you use the function? How do you test and measure wear on new tools you add to your inventory. Do you just have technicians on every machine with their thumb on the button? Help us, Obiwan CNCobi! You're our only hope!
On the part shown at 0:24, the safety wires are going thru the bolt heads on some, and also thru something like a washer on others. Does the washer-looking part have a thru hex? If not, how does that method compare to the thru hole method?..just wondering if anyone has more insight...don't wanna screw up when I start designing aircrafts now. Also, have anyone ever noticed better tool life and/or higher chip loads with using HSS or Cobalt rather than carbide in some materials on tiny holes?
@@brandons9138 I'm not sure what you mean by LFV, but we machine a lot of plastic, the machine can feed in a way were it breaks the plastic swarf up, so it don't go stingy and rap round everything. I stopping working on the shop floor as a CNC turner, because a get in pain standing up all day now. So I've gone over to the dark side of inspection, but I do miss being on a Mill Turn Puma lathe.
@@mw8580 It has to come equipped from the factory with it. The ball screws are specially designed and treated for the extra abuse the LFV puts on them. It's not some thing that can be added later.
Probably been asked before, what software are you using? Titan seems attached to mastercam and we are looking to program a tornos dt38 with mastercam. Would be great to know your thoughts.
Or you could use a Crazy Cross Pilot from Mikron and repeatably pilot on the hex angle, come back in with a crazy drill into EVERY aero space material, and run this lights out through every shift. Crazy Drills FTW
Thanks for the tip. You guys amazing! Can anyone recommend a good .5 inch tool for axial circle milling on a lathe? I have different diameter holes and they have to be chamfered too but my lathe only has one axial station right now so I have to do some multitasking. Can I do this with only one tool. Must be at least 2 inch loc.
