Carbide platen...?

Post removed because my thoughts on the subject apparently bother the OP.

Lots of sweeping assumptions, Stacy. Perhaps portions of this thread have denigrated into a 'group buy', but my query was never intended as such, nor have I implied any such thing.

Your experiences with glass platens are decidedly different from my own, as well as others - some of whom have expressed interest in a carbide platen, in this thread.

There have been several advantages for a carbide platen listed in this thread, as well. If they don't apply to your methods or styles, dandy. However, I think it's imprudent to dismiss the experiences of others.

For the record, I have a friend that's currently using a carbide platen - he only managed to get one of them, but he's asked me to keep him abreast of availability - he says the differences are absolutely worth it. Enough so for him to want two more.
 
Marc, I'm definitely interested in what you find out.

I'm not going to side rail this thread, the people I'm dealing with aren't familiar with these processes, they are the people that make the powders. The actual coating he is suggesting is alumina ceramic that is actually applied by an HVOF spray process and then surface finished. Yes, the coating is in the thousandths of an inch, however they hold up rather well inside gas turbine engines sprayed on critical rotating parts so I think it's worth looking into considering I have direct contacts in the trade and manufacturers. By all means if you can find plates at a decent price, roll with it. I'm not trying to detract from what you're doing. I've been thinking about this since January and this thread has prompted some motivation to move forward. I plan to make an investment, have a few made, put them in the hands of some makers to test drive and see how they perform. If the performance is good enough at a reasonable enough cost I will look into have more manufactured. A couple added benefits to a coating if it performs well enough, it can be re-applied, you can apply it to any shaped object (radius platens), I can think of a few more.

Too many cooks, all trying to use the same grill here! LOL!

I've changed mind on the Carbide. Going a different route. Anyone who wants one of the Tungsten Carbide platen, go here

Call, email, whatever. And look ask for Bill. Explain the size & features you want, & he'll get you a price.

I'm out, peace!

Good guy Bill. I used them when I got my carbide for making file guides.

Edit: One thing I did learn doing business with him, he is just a middle man supplier. Digging deeper to get up the chain closer the mfg and prices could be a lot lower.

Just another option to throw out there, graphite impregnated tool steel.

Might be the ticket for radiused plattens.

I'm very interested on reports from the buyer of these carbide Platens!
The old school trick i was shown 20 years ago was a Graphite Cloth to put on your Steel Platen to cool things down and let the belt slide! It works, still have some in the shop. I just use Pyro Glass these days.

The biggest thing for new people to realize is you will need to flatten that Platen eventually as they get deep scratches and dished out where ever you put the most pressure! I use a 6 x 48" sander. If you or someone you know has a mill? even better...
 
I checked out Alibaba for material cost and its not bad, Asked a mate about getting the finishing part. ITs not good lol

What are some dimensions of a standard platens I can give to my guy so I can get him working on a quote?

Obviously I know the 2" x ??. Mine is 12", larger than Baders, KMG's and the like. Mounting hole dimensions? Basically the whole works. I know some guys like radiused edges, top edge?? Bottom edge??

Me too. Even if solid carbide is the way to go for a flat, I have radius platens I'd like to get coated.

I know you may have a cad drawing of yours.. lol If you happen to have one with all the profiles I can send it to him as well.

Once the coating is sprayed it will have to be finished, and that is the part of the process that is really going to cost. From what he said the coating really is the easy part.
 
The standard KMG is 2"x8", but each machine is different, as you've pointed out.
 
An easy answer to the radiusing the glass platen edges is to get a silicon carbide belt . Very inexpensive by the way.

I just placed an order for some glass platten liners this morning with a local glass shop. Came to $14 each, not bad at all
 
If you really wanted, the lab across the hall from me at my real job is working on super low friction diamond depositotion coatings. I could ask to have a platen coated in the next run they do.
