CNC slab surfacing near Knoxville, Tennessee
Flatten and machine your wood slab for a more accurate final build.
CNC flattening, thickness surfacing, trimming, edge profiling, epoxy-channel machining and hardware preparation for customer-supplied live-edge slabs, hardwood countertops and table tops.
Customer-supplied wood
One-off slabs and matching sets
Powell and greater Knoxville area
Customer-supplied slabs
Bring your live-edge slab, table top or hardwood countertop.
Flatten and thickness
Remove material to create flatter, more parallel faces.
Additional CNC prep
Add trimming, profiles, holes, recesses or epoxy channels.
Local project review
Submit dimensions and photos before transporting the slab.
CNC wood slab milling
Prepare a slab for a table, countertop, desk or architectural installation.
Wide slabs and glued hardwood panels may contain bow, twist, cupping or uneven thickness that makes joinery, sanding and installation more difficult.
CNC surfacing removes material using a controlled tool path to establish a flatter reference face. The opposite face can then be machined toward a more consistent thickness.
Preserve natural live-edge character while machining the working faces.
Prepare the slab for sanding, finishing, hardware installation and assembly.
Coordinate surfacing, trimming, profiling and hardware preparation within one project.
Wood slab milling services
Select only the machining operations your project requires.
The exact scope depends on slab condition, available thickness, geometry, final dimensions and intended use.
Thickness surfacing
Machine the opposing face toward a more consistent final thickness.
Final trimming
Square or trim selected ends and edges to approved dimensions where geometry allows.
Edge profiling
Add compatible chamfers, radii or project-specific CNC edge profiles.
Epoxy-channel machining
Machine selected channels, pockets or cavities for suitable river-table projects.
Hardware preparation
Add mounting holes, inserts, recesses and leg-plate pockets from approved dimensions.
Countertop resurfacing
Review removable hardwood countertops and butcher-block panels for flattening and correction.
Matching slab preparation
Surface multiple pieces toward coordinated thicknesses for paired or grouped projects.
Finishing coordination
Discuss sanding or finishing separately when the project requires more than CNC machining.
Slab eligibility and preparation
Confirm the slab condition before transporting it to the shop.
Photos, dimensions and drying information help determine feasibility and how much material may need to be removed.
Helpful before machining
- Slab has been properly dried and acclimated
- Length, width and thickness are known
- Both faces and all edges are photographed
- Loose bark, dirt and debris are removed
- Known metal or fasteners are identified
- Desired finished dimensions are documented
- Hardware details are available
- The slab can be handled safely
Conditions requiring review
- Severe twist, bow, cupping or cracking
- Limited thickness available for correction
- Unknown moisture condition
- Embedded metal or reclaimed-wood history
- Loose inclusions or unstable voids
- Oversized dimensions or unusual handling
- Existing finish, coating or contamination
- Critical features near the cut surface
Important:
865FabLab machines customer-supplied wood and does not sell
live-edge slabs. Submit project information before delivery.
CNC slab-machining guide
Understand what each operation changes before requesting a quote.
| Operation | Primary purpose | What to provide | What happens next |
|---|---|---|---|
| Face flattening | Establish a flatter first reference surface | Slab dimensions, face photos and condition details | The opposite face may then be surfaced |
| Thickness surfacing | Create more parallel faces and approach final thickness | Required minimum or target thickness | Slab normally proceeds to sanding and finishing |
| Final trimming | Establish approved length, width or square edges | Final dimensions and preservation requirements | Edges may receive sanding or profiling |
| Edge profiling | Add a chamfer, radius or compatible contour | Profile dimensions or an approved reference | Profiled surfaces usually require finish sanding |
| Hardware machining | Prepare holes, recesses and mounting locations | Hardware drawings, dimensions or physical hardware | Hardware can be test-fitted before finishing |
| Epoxy preparation | Create or clean a suitable channel or pocket | Channel geometry, depth and epoxy layout | Epoxy work and final leveling are coordinated separately |

Wood slab milling FAQs
Common questions before bringing a slab to the shop.
Feasibility depends on size, condition, moisture, thickness, embedded material and requested operations.
Discuss Your SlabDo you sell live-edge wood slabs?
No. 865FabLab provides CNC milling and surfacing for
customer-supplied slabs, table tops and countertops.
Can CNC surfacing correct a warped or cupped slab?
CNC flattening can correct many forms of bow, twist and
cupping by removing high areas. Feasibility depends on the
severity and remaining thickness.
Can you surface butcher-block or hardwood countertops?
Yes. Removable countertops and butcher-block-style
workpieces can be reviewed for flattening, surfacing,
trimming and hardware preparation.
Can you preserve the natural live edge?
Often, yes. Mark the edges that must remain untouched and
include photographs before delivery.
Can you machine channels for an epoxy river table?
Suitable slabs can be reviewed for epoxy channels,
pockets and selected leveling operations.
Can you drill holes or recesses for table legs?
Mounting holes, leg-plate recesses and selected underside
features can be added from approved dimensions or hardware.
Does the slab need to be dry?
The slab should be properly dried and acclimated before
final machining. Wood may move again as moisture changes.
How do I know whether my slab fits your equipment?
Send maximum length, width and thickness with clear
photographs. Confirm capacity before transporting the slab.
Will the slab be ready for finish after CNC surfacing?
CNC machining normally leaves tool marks that require
progressive sanding before final finish.
Can you surface several slabs to matching thicknesses?
Matching pieces can be reviewed together. Provide the
dimensions and target thickness for every piece.
