A vacuum chuck is a perfect solution for holding large, thin workpieces, but what about smaller parts where less surface area means lower holding power?

Outstanding video that covers almost all the vacuum tool path and operation tricks I've learned over the years. One other thing about partitioning parts first, leaving a thin floor is that it allows the sheet to become more flexible and better conform to the gasket, pull a better sealing vacuum and hold better for the rest of the run. Another tip is to shut off your air nozzle (secondary coolant) at the end while trimming that 0.010 floor away. You're barely generating any chips from that cut, evacuation is a non issue, but the air stream is surprisingly effective at forcing air under a part and breaking seal. Hopefully the air did it's job earlier and evacuated chips from the slots because the cutter can stuff those under the parts as well. Keep it up, you've proven a very fast learner and an exceptional executor in many facets of the business.

Scope of the vacuum chuck Can it be used on surface grinding machine. Each time need special design for special jobs

@Safiredesignengineer 4 жыл бұрын

Also do you find your part lifts slightly on the seal area due to the seal, or any over hang outside the seal so if you were facing the top face of the parts you will get slight variances in thickness between the edges and the centre of the flat part? A

@Safiredesignengineer 4 жыл бұрын

Hi i see your tooling plate doesn't have any channels under the part for the vacuum only a single small hole? do you not need channels for the vacuum to suck the part down? A

What are the two "set screws" for?

@waaduu6189 3 жыл бұрын

Great explenation, thanks! Is there a need to recess the space inside the gasket in any way to draw a vacuum, especially as there are no channels? Or is everything just in the same plane and the material imperfections or so are enough?

@PiersonWorkholding 3 жыл бұрын

From looking at it, the part and chuck surfaces are smooth, but on a molecular level there is plenty of room for air to move. Keep in mind there is plenty of room between the two right before the vacuum draws them down to full contact.

Anyone done science or something to find minimum weight lb needed to hold down?, as where I am been thinking to put a cnc mill (3040 router) in a slight vacuum to reduce noise when cutting

@carreteFILMSPro 3 жыл бұрын

Impressive although I think milling the pockets instead of going for a straight window cut adds lots of time to the cycle. The cutting tool seems like it wouldn't last long if it wasn't for the blowing gun pointing at it thou, but same as you I would use a str8 o-flt cutter. Well done! It reminded me of a similar job I did once, we used to trim thousands of these lil tabs daily. :)

Its better to deal with chips that wont damage the end mill or work piece rather than huge chunks of material that are cut loose

@CR3DT 4 жыл бұрын

great video. Are the vacuum profiles smaller than the parts being cut?

Yes, slightly smaller by about .020" in from the edge.

A thing to note for your hold down force: The maximum amount of vacuum achieved goes down the higher in elevation you get. Any Venturi pump that will draw 28"Hg (93% efficient) will only draw 25"Hg at around 3000ft. This is important to note when doing your hold down calculations.

@PiersonWorkholding 6 жыл бұрын

Correct! Let's convert that to PSI of holding force. For every 1000 feet of elevation the holding force in psi decreases by a 1/2 lb. So with your numbers, the holding force at 3000 feet is 12.5 lbs per square inch.

So would a vaccum chuck have less holding power at the top of mt everest?

@PiersonWorkholding 4 жыл бұрын

Yes, it would hardly work at all. Maybe 1/2 lb of holding force per square inch.

Are you actually cutting into your vacuum plate slightly?

@PiersonWorkholding 4 жыл бұрын

Yes, by about .010" deep, but only on the first cycle. Sometimes it's a good idea to go deeper the first cycle (~.030") to cut a clearance trough and shallower all the following times just so the endmill has some space under it.

What about the screw holes?

@PiersonWorkholding 5 жыл бұрын

They're also interpolated to leave a flat bottom with 0.010" material at the bottom. The leftover material is easily removed by hand with a countersink which leaves a nice chamfer.

Good video, but it's not a column of air. If air were a solid, it would be a column. But air is a gas, it exerts force from all directions. While the column of air explanation seems fancy, it's 100% scientifically inaccurate.

@PiersonWorkholding 3 жыл бұрын

You're right. The "column of air" is just an easier way to picture it.
