CNC Surfacing & Slab Flattening

Dead flat. Up to 5 × 10 feet.

Bring us your slab, glue-up, or epoxy pour and take home a surface that's flat, parallel, and ready for finish sanding. Our 5' × 10' CNC and 2.5" insert surfacing bit handle work most shops have to turn away.

Big bed. Big bit. Better surface.

Our 5' × 10' bed takes conference tables, bar tops, and door-size slabs in one setup — no flipping, no seams, no piecing together passes from a smaller machine.

The 2.5" surfacing cutter means wider passes and fewer of them. That's less machine time on your job and, more importantly, fewer transition lines — so the surface comes off the machine smoother and needs far less sanding.

A belt sander can make wood shiny while leaving it cupped or twisted. CNC surfacing removes cup, bow, and twist so both faces end up truly flat and parallel to each other. And our insert carbide cutter handles cured epoxy cleanly, making it one of the fastest ways to level a river table after the pour.

What we surface

Live-edge slabs, epoxy and river tables, glue-ups and panels too wide for a planer, end-grain cutting boards, workbench tops that need re-flattening, and reclaimed or odd stock — barn wood, crotch pieces, burls. If it fits the bed, we can flatten it. (We check for metal first.)

How it works

1. Bring us the piece. Call or send photos and rough dimensions for a quote, then drop off your slab. We'll check it for metal, note any cracks, and confirm your target thickness.

2. We surface both faces. The piece is secured to the bed and surfaced with our 2.5" cutter — first face flattened, then flipped and machined parallel. You keep as much thickness as the material allows.

3. Pick it up flat. You get back a uniform surface that typically needs only light sanding before finish. Most jobs are ready within three business days. Depending on our workload.

Pricing

$80 per hour, with a one hour minimum. Epoxy, end grain, and heavily cupped or twisted stock may quote slightly higher due to extra passes. We always confirm the price before cutting.

Common questions

How much thickness will I lose? It depends on how much cup, bow, or twist the piece has. A fairly flat slab may only lose 1/8" per face; a badly twisted one loses more. We measure at drop-off and tell you what final thickness to expect before we cut.

Does my slab need to be dry? Ideally, yes — wood surfaced wet can move again as it dries. We recommend air- or kiln-dried stock. Not sure? Bring it by and we'll check it with a moisture meter.

Can you flatten just one face? Absolutely. Single-face jobs are common for workbench tops and pieces already flat on one side.

What's the largest piece you can handle? Anything up to 60" wide by 120" long fits on the bed.

Will there be tool marks? Our 2.5" bit leaves a very fine, uniform scallop that light sanding removes quickly — far less cleanup than router-sled flattening. Most customers start at 120-grit and are ready for finish shortly after.
