Cutting solid surface3/19
I am considering cutting solid surface countertops for our cabinets. I have an omnitech selexx pal CNC. I have no experience with cutting solid surface tops or installing. I ordered a miter fold bit for HPL that states it can also be used for solid surface. How difficult is it to design? I currently use Mozaik and love the program. I have heard that the material is hard on the machine because the dust is abrasive. How much of the cutting can be done on the CNC like undermount sinks?
If you are talking about Corian or similar products, no problem. I've done it for years. Not with the type of router you have, but with a CNC. I usually cut at 50 ipm. With a good bit your joints will fit perfectly. I have done miter folds but usually I do a double layer build-up. Depends on the top.
I have a big table, 80" x 144" and if I can get the entire top on my table, I cut my sizes to be jointed a touch larger, glue the pieces together and cut the whole top on my table.
I am doing a top know that is 122" x 42", an 'L' shape. I cut two pieces to be glued together. After they are glued, I will apply the edge build-up. Then I will re-position the top on the table, up-side down. To position the top, I will run the completed shape into the top of my spoil board. I will glue the top down with hot melt glue.
Once I have positioned the top, I will cut out for the sink first, then, I will cut my outside edge. I cut this edge which is 1 1/2" thick in three passes. For my step for my cuts, I use .625 which leaves about a quarter of an inch for my last cut. I know it takes longer but with a very shallow cut, I have less concern of my top moving.
If you are not aware most sink manufacturers have templates for their sinks on their web sites. I usually check these. We are now doing some stainless steel sinks by Karran and these are really tight. We have to route the finished edge anyway, so I offset the shape in about 1/16".
