    Which laser source for stainless steel sheet (1-3mm)

    Does anyone have experience with RECI fiber lasers? I was in contact with them and their 1kW unit seems to be interesting (also from a price point of view). Those additional parts shouldn't be a big issue. Height control could be done with some panasonic distance sensor, not a big deal.

    Which laser source for stainless steel sheet (1-3mm)

    Hi, I'm sure there are some people who know a lot about lasers. I was reading through co2 lasers, fiber lasers and diode lasers (last ones seem to be very interesting too but too weak at the moment). Could someone give me some more information how much a laser source would cost which can cut...

    Which pulley type is that?

    Hi, does anyone know which pulley type that is? MXL is close but it's not.

    Threaded/tapped inserts for aluminium plate?

    I can mill pockets quicker than I can order and get any insert. When drilling the holes I can also mill the pockets with no overhead I'm doing all that in the CNC anyway, the pocket operation is not worth to mention it. M3/M4/M6 nuts I have lots of them here. Being too young would be an...

    Threaded/tapped inserts for aluminium plate?

    when I started this thread I was looking for something like timeserts (I didn't know about them until you mentioned them). But aren't they getting loose after some time as well? The hex milling part is quick and easy I wonder why that isn't used more commonly, I made hex pockets for M5, M4 and...

    Threaded/tapped inserts for aluminium plate?

    Hmm? The answers are all useful for me. Some of them divert more than others - different solutions for different use-cases. And it's also useful to know what's available right now and how other people solve those problems. Most of the special solutions were not available in the 1960s though :-)

    Threaded/tapped inserts for aluminium plate?

    did you ever do it that way? it works well and it didn't take too long. The CNC machine is cutting it so I don't care much. In case the nut is worn out I can just replace it easily. All I had to do is to draw the hex nut in CAD, and that's quick too since there's a hexagon drawing function...

    Threaded/tapped inserts for aluminium plate?

    Quite a lot for me, it's a fixture which helps saving a lot more time on the other side.

    Threaded/tapped inserts for aluminium plate?

    https://i.snipboard.io/6cQ7Vv.jpg Here a picture of the result, the last open pocket is not milled with a fine endmill yet, it's currently milling the other pockets.

    Threaded/tapped inserts for aluminium plate?

    hammered some small sticks around the hex-nut into the stock to lock the hex-nut in place. I glued the small sticks in place so they cannot fall out. But anyway I end up milling a hex pocket into the stock that makes it really easy to change worn out hex nuts, certainly a square which matches...

    Threaded/tapped inserts for aluminium plate?

    Today I have milled the hex inserts - it worked better than expected. 1. I drilled the hole 2. I did some roughing with a 3mm endmill 3. I did some fine tuning with a 0.5mm endmill (well I just had that one lying around so I took that one for the sharp corners)

    Threaded/tapped inserts for aluminium plate?

    I'm using 6060 aluminium, the cost for the first item seems to be a bit too expensive (+time until it will arrive). I think I'll just go with cnc milling a hex pocket and put a regular nut inside, I have not tried that yet. I need inserts for M3 and M5. Previously I milled a bigger hole and put...

    Threaded/tapped inserts for aluminium plate?

    Hi, can anyone recommend a threaded / tapped insert for an aluminium plate? The aluminium plate will at least be 10mm thick, it should be a fixture for some other parts but I don't really want to tap the aluminium itself because it will wear out sooner or later. How about rivetnuts or wood...

    Securing tapered roller bearings

    how luxury, my nut only had 1 slot on the side but two screw holes so I guess they just skipped the second slot. Also initially it did not even came with a screw it was just loose (I have added that myself when I figured it out but it's still too weak).

    Securing tapered roller bearings

    Hi, I have a chinese mini mill here, which I have converted to CNC. Now every now and then the fastener for the tapered roller bearing is getting loose. I have fastened that part around 3 times so far. https://snipboard.io/dSLXFp.jpg (please admins fix the picture upload, I cannot select a...

    How to manufacture / bend small copper u-channel // Tape Cover

    I also succeeded with the 120mm u-channel, I will make some better jigs for bending it next week. For now I finally squeezed it into a vise and it folded it just nicely. Double sided bending for sure is easier than single sided. Maybe I should also heat up the material before pushing it into...

    How to manufacture / bend small copper u-channel // Tape Cover

    ok the 20mm U-channel worked with a fairly good accuracy and reproducibility (as I was hoping to..) Dual side bending seems to work well, single side bending maybe if I'd do some v-grooving otherwise I'd have no faith in that with my amateur tools. Next would be the 120mm U-Channel, I also did...

    How to manufacture / bend small copper u-channel // Tape Cover

    I have no particular equipment yet for it (in terms of a press), however I have a small CNC machine as mentioned earlier and some tools which I'd like to abuse for that task. - I'd first try to hammer it in (prototype) - secondly I might try to press it in with some big screws on the side. The...

    How to manufacture / bend small copper u-channel // Tape Cover

    Thank you for following up. The u-channel which I'm working on is only 3cm long and 0.8mm thick. I need to bend 2 u-channel parts in total; First I'll give the smaller one a try. There will be some overhang outside of the die which should allow to remove the part easily. The longer u-channel...

    How to manufacture / bend small copper u-channel // Tape Cover

    I'm focussing on the u-channel first. I have another part which needs a 7.5mm bent u-channel, goose necks seem to be difficult to handle especially since all the sidewalls need to be equal in size to match some drilled holes. How about something like that? the blank will be screwed with a...
