I recently picked up a little CNC router. Its got decent (not perfect, but
decent) ballscrews and decent linear rails. I am taking apart the stuff I
don't like, upgrading the motors, spindle, controller etc.
One thing I would like to upgrade is the table itself. Its got a 20x20
style extruded t-slot table, but its awfully soft and not very uniform. My
Taig and my MaxNC mills both have aluminum tables, but they are a lot more
rigid than this hollow extrusion. To get something decent at a good price
am I going to have to just wait until I get the big mill going (been working
on it for a long time) and just make my own table?
Suggestions? Ideas?
I did consider just going with a couple pieces of mill rolled aluminum plate
with drilled and tapped wherever I need a hold down. Surface as needed.

Re: T-Slot Plate
Maybe drill a large blank plate for pins, and drill / counterbore up =
through it from the bottom so that you can then attach a row of =
"tee-shaped strips" onto it's top.
Then, once the strips have been attached and the whole mess is installed =
onto the machine, you can lightly fly cut across the tops of your "tee =
shaped strips" in order to true it in....
Re: T-Slot Plate
I have a very nice T slot table for sale.

Re: T-Slot Plate - Looking At
machined. Not extruded.

Now I could find that in cast iron instead of aluminum for a smoking
price...
Re: T-Slot Plate - Looking At
Hmmm... never saw that. Still thank you. The claim the bottom is good
enough to seal up to their vacuum plates. Either they have some impressive
gaskets or they had to atleast surface the bottom.
Makes me really really wish I could get inspired to finish the Hurco. with
its 24 by 14 working envelope I could use it to make every part except the
screws and electronics for machines this size.
Re: T-Slot Plate - Looking At
Its gotta be better than the extrusion used as a table on this machine now.
This is going on a small router so clearance is an issue as well.
Its one reason I considered just throwing some mill rolled flat bar stock on
there and then drilling and tapping for mounting stuff as needed.
