Where do you get thin metal cut? Sendcutsend only cuts aluminum down to 1mm. Need .30mm cut.
get 1.2mm thickness and then cut it in half twice.
you buy the material and give it to a local laser cutter and ask them to cut it
>>2975277This. Find someone local with a laser or water jet cutter. If you want to mass produce you may be able to convince a machine shop to stack the plates for cutting multiple at once as well.
>>2975277I mean unless it's super precise shit op could just use tin snips for something this thin.
>>2975240Is pic rel the actual part you need cut out? How precise does it need to be? How many of them do you need?
>>2975240I'm having a similar dilemma. I want to do some small, precisely cut thin brass stuff (numerals for a clock etc.), and annoyingly I have access to a laser but it can't do metal, plasma is overkill, don't have a waterjet, etc. We're about to upgrade to a more powerful laser that COULD do it but won't have it in time for what I want to do either.
>>2975287I hope a laser can cut through this stuff. Waterjetting would work but I think all the places in the area would tell me to get fucked. For mass production if needed I think these could be stamped. The sheet just rolls over a cutting die and should be thin enough to do tons of them extremely fast. Much faster than a laser.>>2975523Yeah pic related is the actual part. It needs to be pretty decently precise as its a part of a rotor that will probably be moving at like 20-30k rpm. Will take some balancing in the post processing, but if its too far off I don't think it would ever really be balanced. Probably need like 20-30. They are about 3.5" disks i believe and theres also spacers that go between these discs that need to be cut as well.
>>2975240There are 3d printers that can create metal products.
>>2975613>For mass production if needed I think these could be stamped.Yes, this would definitely be the way for mass production. The interior slots are going to be a pain in the ass to do with any other process than a CNC waterjet or laser... the 20-30 part count makes it more than one would ever want to finish by hand, and not enough to warrant a quantity discount for mass production...
>>2975631Ohh you could try someone with a small CNC engraver, or desktop CNC mill. using a small engraving bit could allow you to cut through such a thin piece of material. Of course cut the inner parts out first and then finish by cutting the outer diameter so your work stays supported during the entire operation. Cut your blanks oversize and put a few screws through them into a sacrificial aluminum or plastic backing plate to hold the work down.
>>2975610use the old printed circuit board method, laser printer toner transfer sheets and a ferric chloride etching bath
>>2975669I thought about something like that. I may be able to skip the masks and just spray stuff on the metal and then laser it away before etching too.
I ended up swapping the metal discs for carbon fiber. $70 total landed cost for 66 discs from a factory in China. Were I to do this with aluminum just the raw materials alone would probably be $30. From a production standpoint the discs could be made quicker with stamping but the aluminum comes in rolls so there would probably be some warping unless it went through a roller. The aluminum is also I think like 40-50% more heavier than carbon fiber by density. So looks like I will be doing these with CNC for now and potentially maybe stacked in a waterjet in the future should my prototypes work. If anyone needs the email for the carbon fiber cutting just let me know. Will hopefully have the parts soon to see how the quality is.
>>2975240Go to a Photo/Chemical Etch place.
>>2975613You can just go ask local machine shops.i got something similar done by a local shop and he charged me a flat rate of $40 and said he could do up to X quantity for that price. Laser cutting, not as thin as yours. Only paid for the (scrap) material of his choice and about 15 minutes of his time. I had asked 2 other shops. One said no and the other quoted me $500+. Different shops have different flexibility and friendliness. My shapes were simpler than your pic also
