I like to have things done precisely how i want them. So i decided to make my own vacuum fixture plate and custom gasket. Which has to work exactly as i want it to work.
I think the Idea is good and worth sharing
In this video i will show the entire process of:
mould making - cnc milled out of 10mm thick acrylic.
casting your own gaskets.
milling your own custom vacuum fixture.
laser cutting part blanks for vacuum plate.
demonstration and explanation.
cutting final part.
This what i like most about this process is speed in which you can have custom gasket made, without wait on shipping.
Another benefit is that you can have any shape you want and it will cost you almost nothing.
silicone manufacturer info:
Mold Star® silicone (32$ for 1 liter) cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage. rubber is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys.
shop.smooth-on...
Another benefit is ability to have those gaskets taller than rounded ones which allows to suck down even badly bowed parts.
I'm not getting paid to sell silicones, i just use to use them a lot.
And i will always share information about good products if i find one.

You have done a really good job of building your mill. A lot of new ideas that work great. It may be the best mill design I've ever seen.

@neatpleats11 6 лет назад

I just started watching your video's and I am always on the edge of my seat. The most I ever cut on my CNC machine is wood so watching you cut aluminum is enjoyable. I feel like you are actually teaching me. Thanks so much.

@PiotrFoxWysocki 6 лет назад

I'm glad you like those videos. I would never expect that they are so edgy :) I'm sorry if you find me trying to teach people. this is the last thing i wanted to do, I just want to explain particular problem so everyone understand my motives of solving it. I just want to share some ideas and perhaps different approach. Or maybe I'm just scared of a word teacher :)

Next level or madness? An interesting question that requires perspective. Business perspective.........minimum cost and time necessary to get the job done. Anything else is ....waste. There are other perspectives. Consider your perspective and do your thing. Good video as always and good question. Yeah, I know it's an old vid but interesting nevertheless.

Interesting application of a vacuum plate. More like fixturing. And a good application of that to! I like the results of that new spindle. Top quality milling. And thankfully not a screamer like so many other lesser quality spindles. Mark

@miodragstanojevic4100 4 года назад

Nice one, what are the rules for the groove dimension and the gasket for that groove? If the width of the groove is 6mm, what would be the depth? And thickness the gasket would use? Tnx

@PiotrFoxWysocki 4 года назад

it all depend of the gasket you use. if its a hard gasket than on the grove 6mm wide i would make depth of 5mm. if its softer maybe 4.5 so you will have 1.5mm stick out. i would recommend to test gasket compression and than make grooves accordingly.

@dmitribovski1292 6 лет назад

Cool thanks. If you are going to be producing lot's of those plates using the perspex to block of one side then the other seems a waste of time. You need 2 programs for this job one to produce the first side. The second produces the first and second sides in one operation when you have the chamfer tool in for the first side you may as well clean up the pocket on the second side.

@PiotrFoxWysocki 6 лет назад

I like to have flexibility, if i want to make just one at the time.I will use 2 programs. if i want to make more of them, then i will use one program and 2 plates on both sides. I didn't mentioned about it on the video because i thought it is obvious ;)

@CassioVA 5 лет назад

Man, this is an stupid volume of coolant, its like a waterfall... I like it!

@jamieclarke321 6 лет назад

could you use a silicon gun and just inject normal silicon into the mold to make more gaskets?

@PiotrFoxWysocki 6 лет назад

I like the way you think :) in this particular mould with cover it wont work because regular silicone need air to cure. inside closed mould it will be just like inside the tube you squeezed it from. but perhaps you could experiment with open mould (no cover) and try to see if you can smear it so its flat or perhaps put more and cut excess with a razor. if your idea will work, it could be even easier/ more available for everyone to make their own gaskets.

@jamieclarke321 6 лет назад

Ahh didnt think of that, good point

@randomname3894 5 лет назад

@PiotrFoxWysocki 5 лет назад

@kentvandervelden 6 лет назад

Very interesting next-level madness Fox :) In the mold making, will the silicone naturally level out without needing to be pushed or a vacuum to help out gas? With your final cover plate, do you punch out the milled area by hand and debur?

@PiotrFoxWysocki 6 лет назад

there are 3 ways you can deal with silicone. 1) natural way mix it and hope there won't be too many bubbles. if you using slow curing silicone most of trapped bubbles should escape before it will cure. 2) after mixing you degass it in a vacuum chamber. 3) after mixing you cast it in a pressure pot with high pressure like 80 psi to shrink any bubbles in to nothing pretty much. There are as well plenty of variations of those 3 methods. silicone will level out by it self, it depends on the curing time and the the distance it has to flow through. with the cover plate this milles area is for bottom of the joystick which is inside the case. to make the case as compact as possible i have to mill out this bit. It won't be punched but i guess i could put a chamfer on it. Im still dialing all the details. but if i would have to mill a hole in it i would put a round gasket outside of the hole. i can't deal with clamps anymore. I had to run a big batch of parts and clamping and unclamping was taking more time than milling..

@jamieclarke321 5 лет назад

More videos please fox. This machine is amazing and I’d love to more of it running

@PiotrFoxWysocki 5 лет назад

watching it running is a bit disappointing because flood cooling is covering everything. when i turn it off then chips are flying everywhere and running it without coolant might damage endmill and whatever i'm milling. if you have any suggestions, you are most wellcome.

@jamieclarke321 5 лет назад

Check out edge precision’s RU-vid channel. There’s always lots of coolant and chips flying there but it is all the processes of machining that is so interesting and the fact you are using a granite CNC with high end Chinese spindle, there is no one on RU-vid doing that

@PiotrFoxWysocki 5 лет назад

ok, next time if i will be milling something and its not a "top secret" part i will try to make a video. (recently i have very limited amount of time, even for sleeping. so please forgive me my absence in making videos)

@michaelpilliod1039 6 лет назад

I don't know how much power you have available, but I often run a 2" face mill at 120ipm .02 on my vacuum plate without any issues. The plate will hold as long as you have area to grab on to. Even with much less power you can probably deck it off faster with a wider tool and deeper cut. I would look at datron's tool. They have an insert tool they run and their spindles are pretty low power if I recall.... You might even try a single flute indexable end mill with a PCD insert.

@PiotrFoxWysocki 6 лет назад

i was a bit concerned about the speed outside of the gasket. but thank you for the advice on speeds. Also naturally i start thinking about Datron's tooling. don't have any experience with them but now with the new spindle it seem to be a logical step forward. are those single flute ain't more fragile ?

@TheEppicJr 6 лет назад

I have a similarly spec'd cnc mill to you, i have tried Micro 100's single flute endmills (these are cheeper and in theory not as good as the datron ones) and they are pretty good at the higher rpm's, I am able to take similar cuts to the ones you made in this video and I haven't even tried to push it yet. In theory you get much higher material removal rates in high rpm spindles because for every rotation you only have one cut instead of 3. In terms of Datrons other offerings like their PCD facemill and normal facemill they only come in HSK E25 so we cant use them.

@michaelpilliod1039 6 лет назад

I've never tried a single flute or a Datron, but when I saw your machine that's what I was reminded of. I'm using a Haas TM2P. So the cutting forces on my machine are much higher. That being said, I won't hog out material with a large end mill (say 16mm) unless I'm covering most of the surface area of the 13.5" x 20" vacuum chuck. For smaller parts say 6" x 10" I still face it at 120 ipm with a 5 insert Sandvik 245 or a 3" 590, and .010" DOC. Then for material removal I use a 1/4" 3 flute end mill. For you machine you may not be able to run a ton of flutes due to power and rigidity, and the face mill would definitely not be an option, but it's an example of what you can get away with on vacuum. I would look at PCD tooling because the surface footage is insane and would let you get the RPM's up on the spindle. BTW I looked and the Datron tool is only an HSK taper. You may want to look at a Sandvik 390 with 1 or 2 inserts. I think they make PCD for that tool.

Nice fixture, the fit of that plate when you flipped it was very satisfying! Have you considered drilling some holes through the fixture into your base plate for some dowel pins so you can realign more easily in the future?

@gabibalsanu1558 6 лет назад

How do you calculate feeds and speeds?

@PiotrFoxWysocki 6 лет назад

by a hunch :) every machine is different and even if you change one part it will affect feeds and speeds. so you have to test how machine behaves and size of the chips. and over the time you will get the idea what speeds are working for you.
