CNC router vs panel saw: which suits your cabinet shop
Nesting CNC router or panel saw for cabinets and furniture? Compare yield, labour, drilling, edge quality on melamine and when a shop needs both machines.
For custom frameless cabinets where most parts need holes, grooves or shapes, a nesting CNC router does more work with fewer people. For large runs of plain rectangles, solid wood and stack cutting, a panel saw is faster and simpler. Many growing shops end up with both: the router for machined parts, the saw for the rest.
Two ways to turn a sheet into parts
A nesting CNC router holds a full sheet on a vacuum table and cuts every part out of it in one program, drilling shelf-pin and hinge holes and cutting grooves on the way. The Holz-Her DYNESTIC 7532 carries a 15-spindle drilling head and a grooving saw next to its router spindle for exactly this. The Laguna SmartShop 2 Pro does the same job at a smaller scale, with an 8-position tool changer and a 6-zone vacuum table.
A panel saw cuts sheets into rectangles with straight through cuts. On a sliding table saw the operator moves the panel; on a beam saw such as the SCM gabbiani s a program fence pushes single panels or stacks under a pressure beam and follows an optimized cutting list. Drilling and grooving then happen on other machines. For the difference between the two saw types, see sliding table saw vs beam saw.
Router vs saw at a glance
| Point | Nesting CNC router | Panel saw (sliding or beam) |
|---|---|---|
| Material yield | High on mixed sizes and shaped parts, which can go anywhere on the sheet | High on repeated rectangles with optimization; limited to straight through cuts |
| Labour per job | Low: load, run, label, unload | Higher: cut, sort, then drill and groove elsewhere |
| Drilling and grooving | In the same program | Separate boring machine, jigs or router |
| Curved and shaped parts | Yes | No |
| Edge quality on melamine | Clean with compression bits and good hold-down; small parts need care | Clean with a scoring blade; very straight edges |
| Identical rectangles in quantity | Slower, one sheet at a time | Faster, especially stack cutting on a beam saw |
| Solid wood | Limited | A sliding saw rips and crosscuts it well |
| Skills | CAD, CAM and nesting software | Saw operation; optimization software on beam saws |
| Downtime risk | Every part goes through one machine | Other saws or the router can cover |
| Comes out best for | Custom frameless cabinets and mixed jobs | High volume of standard parts and mixed materials |
Material yield
Nesting software places parts anywhere on the sheet and can rotate them, so small and odd-shaped parts fill gaps between big ones. HOMAG describes nesting as especially suited to small parts of different shapes, with waste kept down by the layout. A saw is limited to cuts that run right across the panel or strip, so its layouts are more constrained, but a beam saw with optimization software is very efficient on repeated rectangles. One experienced shop owner on WOODWEB reports 4 to 5 percent better yield from a beam saw with optimization than from a sliding saw.
Two details narrow the gap. A router bit removes more material than a saw kerf, so tightly packed nests lose some of their edge, and grain direction on veneer or textured melamine limits rotation on both machines. On a typical kitchen with mixed part sizes, yields are often close, with nesting ahead when there are many small or shaped parts.
Labour and throughput
The router's main advantage is labour. One operator loads a sheet, the machine cuts and drills every part, and parts come off labelled and ready for the edge bander. HOMAG lists fewer staff, fewer errors and less part damage among the benefits of nesting. A WOODWEB contributor weighing the two estimated that a panel saw would save 1 to 2 hours per kitchen, while a CNC router would save 1 to 2 days, because drilling and dados come off the same machine.
The saw wins on repetition. For large quantities of the same part a beam saw outruns a router, especially when it cuts stacks; WOODWEB contributors put the crossover somewhere between 20 and 100 identical parts. Below that, the router's lack of setup time takes over.
Drilling and machining
Vertical drilling, grooves for backs and drawer bottoms, and hardware cut-outs all happen on the router in the same program. Horizontal holes in panel edges, for dowels or some connectors, need either a separate machine or extra equipment: Biesse's Rover Multi Go N G, for example, holds vacuum pods on its table for edge profiling and horizontal boring. A saw-based shop needs a boring machine or jigs for all of it, which adds a handling step and a place for mistakes.
Edge quality
On melamine, a panel saw with a scoring blade gives straight, chip-free edges on both faces, and beam saws such as the HOMAG SAWTEQ S-100 adjust the scoring saw from the control. A router gets clean edges with compression spiral bits, which cut downward at the top face and upward at the bottom. One cabinet shop on WOODWEB reports about 80 sheets per compression bit, which made its router tooling cheaper than its panel saw tooling.
The router's weak point is small parts, which can shift on the vacuum once they are cut free. Onion-skin passes, tabs or a slower final pass solve it at a cost in time. Either way, a premilling unit on the edge bander, standard on the Felder G 383, trims a fresh edge before gluing and evens out small differences between the two methods.
When to have both
Once the router is busy, cutting plain backs, shelves, fillers and toe kicks on it wastes machine time. A panel saw takes those parts, handles solid wood and oversize panels, and keeps cutting when the router is down for service. That is why many shops add a saw before a second router. Our cabinet shop machine guide covers buying order and edge banders.
What each needs in the plant
- Router: a vacuum pump, dust extraction sized for full-sheet cutting, three-phase power (600 V in many Canadian plants), a loading area for full sheets, and someone who can run the design and nesting software. A WOODWEB contributor advises spending 6 months to a year learning the software before the machine arrives.
- Panel saw: dust extraction and clear floor length. A sliding saw needs room for the carriage stroke on both sides of the blade; a beam saw needs space for its air tables and for feeding full sheets.
How to decide
- Most parts need drilling or shaping, sizes vary job to job, and skilled saw operators are hard to find: nesting router first.
- Standard boxes in volume, face-frame parts or a lot of solid wood: panel saw first, with a boring machine.
- Router already full: add a saw for the rectangles.

Questions and answers
Is a CNC router or a panel saw better for a cabinet shop?
It depends on the parts. A nesting router is better when most parts need drilling, grooves or shapes and labour is short; a panel saw is better for high volumes of plain rectangles and solid wood. Many shops use both.
Does nesting on a CNC router waste more material than a panel saw?
Usually not. Nesting fills gaps with small and shaped parts, which offsets the wider cut of a router bit, while a beam saw with optimization software is very efficient on repeated rectangles. Yields are often close.
Can a CNC router cut melamine without chipping?
Yes, with compression spiral bits, correct feeds and speeds and good vacuum hold-down. Small parts need onion-skin passes or tabs so they do not move once they are cut free.
When should a cabinet shop add a panel saw to its CNC router?
When the router spends much of its time cutting plain rectangles such as backs, shelves and fillers. A saw frees router time for machined parts and keeps cutting when the router is down.
