Brilliant, I’m going to buy one of these soon. Another tip for vacuuming. When making tiny parts, we’ve gone as small as 7mm x 18mm, stick your stock, using double sided tap, to a sacrificial board. We use 2mm foam. This also means you don’t have to create these custom tops. This method is great when you have MQL.
Who doesn't like a quickie? I for one wouldn't mind twice the length, show some footage (I love how we still call it footage without feet of tape) of your awesome machines throwing chips! Thanks for sharing.
It'd be great to see how you design your custom plates like this in CAD, do you have a template, or general rules of thumb (like the .050" depth you mentioned)?
I designed one in real time in under 12 minutes here: ua-cam.com/video/GxgN30mGXSU/v-deo.html Tabs technique still requires some type of clamping fixture that would need to be designed and there's secondary processing of breaking off the tabs. Vacuum parts come off 100% complete.
Mr Pierson, I'm sure you're very smart and doing fine, but if I could, as a true admirer of yours, give an opinion, in your shop labels, charts and all the lean stuff, when you get the time, make it big, maybe like a child would like to see and understand. Greetings from Brazil!
Never used a vac chuck or machined something thin enough to really need one but I can for sure see its advantages and how it can be the right tool for the job.
How do you deal with the deflection in the part through the pressure and the gasket? When the part needs to be very flat i can see this becoming a problem..
Just the opposite... vacuum chucking is the BEST solution when parts need to be flat because the part is firmly pulled fully flush with the fixture surface. The gasket easily compresses into the groove it sits in. Here's a quick look: ua-cam.com/video/tHSnB5Z_MQc/v-deo.html
Hi, I am woodworker with Cnc and i tried to deal with vaccum table like you do. I have some questions : Do I need to continuslylet run my vaccum pump ? (I have a 9 liter ballast + membrane pump) -How can I make / find customs gasket to fit with a cutom design shape (like you do) -Which gasket is best to use ? How do you deal with top of your vacuumtable paraleism ? Best and Thanks

I use a similar fixture approach with a part I am making. My stock is 0.175 thick and 8” x 8” area under vacuum. How hard can you drive the cut to separate the scrap from the finished part?
You have almost 900 lbs of vacuum force. I'd rough machine the perimeter of the part first but leave .015" of material left at the bottom to keep the scrap and part connected. Then take a finish pass at full depth to separate the two. This allows you to push harder and use the surface area of both pieces to increase holding power during the rough.
Good video Jay. This would be awesome for a small production run. For a one off, super glue technique is probably the way to go. I'll have to keep this in mind for larger runs :)
Yes, for 1 piece I would not recommend spending money on a customizable top plate, but here's a technique for 1 off parts: ua-cam.com/video/Ol_EGDYyogM/v-deo.html
Our gasket material can easily turn a sharp corner, as it does in the grid pattern of our chucks, but a radius of 0.100" (2.5mm) will help extend the life of the gasket.
What i would do is send the drawing to someone who has a waterjet of laser cutting machine Cheaper in every way BUT, it is a realy nice solution with the vacuum plate!
@@PiersonWorkholding when did lasers or water jets get to the point where they can machine the top surface smooth, create beveled and contoured features, and give it a precise thickness? I haven't seen them on UA-cam yet!

Awesome information in each episode. Maybe in a future one you do more of a tutorial on how to use the different mitee bite clamps.

How much time would you say it takes on average to build a custom vacuum fixture? And how does this compare vs machining and leaving tabs?

Wait you did not demonstrate the fixture making the part! Not even holding it. I would want to see that.
Yes we did! Here's the video: ua-cam.com/video/-hFzE1Qkb3g/v-deo.html
For plates, datron style vacuum plate is probably the go to. You don't need to make any custom fixtures.
Yes, Datron is a fantastic $200,000 solution!
@@PiersonWorkholding You can buy just the vacuum plate and mount on any machine, or better yet make your own and just stock up on vacucards.

you don use rubber as a shere hold on to keep part in place

What's the smallest radius on a corner for the gasket? Can it go around a sharp inside edge in the groove or is there a min. radius requirement?

Haha! Especially those waterjets that can tap holes holes and leave a machined edge.

electromagnets work well also
not on aluminum
