Double Side-Tap to hold down Plate

[Bill Sutton@Accurate Machine]

Hello,

Looking for the best double sided tape to hold down Aluminum. Machining a big plate that has some .06 floors left lift to give a liitle support.

 

I know 3m makes all kinds. Just looking to see if some has use a particular kind.

 

Thanks

Bill

We somtimes use carpet tape, it's a little thicker and holds more than regular tape. we get ours just at a hardware store, just any old brand.

The thicker carpet tape has thickness variation issues. There is also a thin carpet tape that does not have the thickness variation issue.

 

3M makes an awesome tape, 667 I think, very good adhesion, good coolant resistance, and much easier removal than lots of em.

Mitee-Bite sells some heat acvtivated adhesive in sheets that works better than any double sided tape I've used. Kind of expensive but holds better, closer tolerance and easier release and clean up.

We use 3M #410 tape for this kind of stuff

Double sided tape has gone by the wayside in our shop.

John,

We have a 5' X 12' router and forever are cutting thermoform tools that easily cover 95% of the table. As you would expect I have to machine one side flat before fliping and cutting surf geo. I have tried many things to try and just let the part sit in a normal state, push clamps always seem to pull down on the part and when I release the clamp that corner or side raises up and I'm back to a non flat piece of material. I am very interested in the Wafer Grip. Is it expensive and if it is how do you think it would work if I just put in 4 or 6 places just ot keep the part from moving around the table while facing at 350 IPM @ 9500 RPM.

 

email me [email protected] with any info you might have that would persuade my boss to give this a try.

Thanks

Terry

We use double faced tape from 3M

 

It is .004 thick, 1" wide PAPER backed. I say this because they also make the same tape in plastic back and it just doesnt work at all.

 

I dont know where our purchasers buy it. Perhaps Newark electronics or Graingers.

I've used this tape since forever. It is about .006 thick and very consistant. Sometimes with warped plates you have to put on 2 or 3 layers in a 3 point patern. Or 1 strip and 1 small spot to keep the plate from "wobbling". Test it by hand before hitting the plate with a cutter, if you can move the plate by hand it's not safe!! Take small cuts (.002 - .005) until you have enough clean-up to flip the plate over. Tape to a good, flat machined surf and you can take .020 cuts with a flycutter.

Terry,

 

I don't think you'd be able to use it in that application, it is heat activated, so you h ave have to place that entire part into and oven or at least onto to localized hot plates to get the activation from the strips.

 

Ath e sppeds and feeds you quoted I don't think double sided tape will do you much good either, unless it is just a dust cut.

[BernieT]

Terry, check out this stuff. It's not an adhesive but can be molded under and around the edges of your plate to hold it. It's reusable too.
