I'm getting well into my build now and need to choose a bed that the job will be mounted to. I have looked at aluminium box extrusions but find it really pricey for the runs I would need to make.
Where did any Aussie guys find their beds?
I was considering getting a 6mm stainless plate with 12mm holes drilled spaced every 150mm in a grid.
What do you guys suggest?
Australia or the North pole, all is more or less the same. Please take a look at my thoughts on the subject #165 with detailed price comparison . It's in Euro but even in $ preces are similar and relations between them also. My personal choice is 140 UPN profile for a serious machine.
How about tooling plate?
I'm currently building a router with a 30mm bed.
Not sure about the grid for the holes yet, but the machine will make them by itself.
I would never choose stainless though, too difficult and expensive.
http://www.actionaluminium.com.au/index.html They have interstate branches! QLD has the bigest stock/range.
Give them a call and see what they can do for you. In Melb they are quite friendly.
Here is the trick.. If you are thinking of making production run parts think about making jigs and the attachment of those jigs.
If on the other hand you intend to have a big plate with dowels and threads then it is a lot of money and rarely used to its full capacity.
I did a similar design that had a series of pedestals that supported a number of plates.
At the end of the day we ran a dial mic over the jig and adjusted the jig so as to have finished parts within tolerance.
Moral of the story .. figure out what you want to do and design to meet those needs. bolt it on so as to have flexibility if the goals move or change. example " oh dear a plasma cutter would be nice"
Now we need a fume extraction or water bath as a bed.
I don't mean to confuse the issue, a good plan and a set of goals is more that half the work.
Thanks for the heads up.
