- Solid Carbide
- 0.118" Diameter
|
 |
The 0.118" diameter endmill is used to cut slots for the vacuum gasket. The smaller slot width puts just enough compression on the gasket to hold it snugly in place.
SV2-Endmill - $16.00

- Two Double Clamps
- Two Bolts
- One T-Fitting
|
 |
Whenever operating multiple Bases from one VCU, use the set of double sided toe clamps in this kit to mount the Bases as close as possible. The T-fitting is used to daisy-chain the air line to both Bases.
SV2-Twin - $35.00

The short answer - Multiply a part's surface area by 14 to find the downward holding force in pounds.
The long answer - The holding power of any vacuum chuck system is measured by the amount of air it can remove from under a part. You'll see this air pressure measured as "Inches of Mercury" or "Hg and measures about 30" Hg at sea level. A perfect vacuum is when all the air pressure equals 0" Hg.
It is nearly impossible to create a perfect vacuum on Earth however the SmartVac II vacuum chuck draws a 94% or 28" Hg vacuum. This is equal to 14 psi. This means a 6" x 6" part (36" of surface area) will be held with a force of 504 pounds (36sq.in. x 14psi = 504lbs).
The perfect part has a large surface area and with a small thickness cross section. Materials can range from plastics to metals. Harder materials can increase side loads during cutting which can slide a part off the chuck so lighter feedrates and depths of cut should be observed. One tip to overcome part movement is to sandwich a piece of 220 grit sandpaper between the chuck and the part to increase friction.
The SmartVac II VCU draws a vacuum equal to or greater than convential vacuum pumps. Plus, the system is low maintenance since it does NOT require particle filters or coolant traps. Other systems require an electrically powered pump where the SmartVac II runs off a small amount of compressed air. The chuck portion of the system has nine vacuum inlets allowing up to nine individual parts to be held simultaneously where other systems only hold one part at a time. Pricewise, the system is far less expensive to purchase AND maintain than traditional systems.
This is easily done by attaching a Top Plate to the vacuum chuck surface and milling a gasket groove just inside the part's perimeter. Any through holes in the part need to have gaskets around them so the vacuum isn't lost when a cutter breaks through the bottom surface of the part. If the finished part has very thin features (imagine cutting out the letter O), consider leaving .002" to .005" of material at the bottom (the inside of the O) to maintain a larger vacuum area. Depending on the material, you should be able to easily pop out the center section by hand.
Yes! The SmartVac II is perfectly suited to handle large parts. Multiple bases can be setup adjacent to each other using a Twin Base Kit. This kit contains everything needed to chain multiple bases together and operated by one VCU.
