Oficina de fresagem CNC · CNC de 5 eixos
Um centro de maquinação industrial de 5 eixos com troca automática de ferramenta: fachadas de móveis (3D e curvas), produtos esculpidos, portas, escadas, sinalética. Barreira de entrada elevada — um nicho premium.
Um projeto da Gravity LLC.
O trabalho complexo vai para as oficinas com 5 eixos e automação. Sem isso, uma oficina desliza para a subcontratação de baixa margem.
Premium walks away
Curved and 3D fronts and complex millwork — the highest-margin work — go to whoever has 5-axis.
Outsourcing won't last
Today shops without 5-axis send the hard work out. Tomorrow the shop they send it to takes the simple jobs too.
The window is closing
Few such machines exist in Sacramento and the Bay Area. Whoever installs first owns the niche; the rest pay them.
Qualquer concorrente pode instalar esta máquina. A questão é se será o primeiro — então o trabalho complexo e a subcontratação fluem para si, e não para longe de si.

Como funciona
1 · CAD/CAM
Program the facade or pattern (woodWOP / Maestro / bSolid + Aspire for relief).
2 · Work-holding
Pod-and-rail consoles or a vacuum table — hold the part with no re-fixturing.
3 · 5-axis machining
ATC and aggregates: 3D/curved facades, undercuts, angled boring, carving on contoured surfaces.
4 · Finish
Sand, paint/stain, accent the relief.
5 · QC & packing
Label parts, check geometry, assemble the order.
Gama de produção
O centro de 5 eixos não é uma aposta num único produto. As frentes de móveis criam a carga de base, enquanto a marcenaria, os moldes, a sinalética e o trabalho por encomenda suavizam a sazonalidade e os tempos de inatividade.
Cabinet fronts and facades
3D and curved fronts, ribbed/fluted surfaces, classic raised-panel doors, shallow relief in MDF and solid wood.
Doors, windows, stairs
Arched rails, curved handrails, volutes, stringers, balusters, posts and complex joinery with minimal re-fixturing.
Panels, fences and decor
Carved wall/fence panels, acoustic and geometric surfaces, decor for restaurants, wineries, HOAs and parks.
Sculptural furniture
Chairs, tabletops, bases, curved laminated parts and organic forms where 3-axis machining is not enough.
Patterns, molds, prototypes
MDF/model-board/foam plugs for vacuum forming, composites, concrete, exhibit pieces and product prototypes.
Signage and retail fixtures
Dimensional sign blanks, exhibit pieces, counters, display bases and acrylic/solid-surface/wood components.
Jigs and job-shop work
Fixtures, templates, angled boring, short runs and outsourced work from shops without true 5-axis capacity.
Product
Cabinet facades (kitchen doors/fronts, incl. 3D and curved) for the B2B cabinet-shop market; plus carved panels/fences, doors/windows/stairs, signage and 3D decor.
Differentiator
True 5-axis + ATC is a high barrier: few local shops make curved/3D facades and complex millwork. A premium niche with outsourced demand.
Market
Sacramento ~2.4M + Bay Area ~7.7M — a large kitchen, furniture and millwork market; shops without 5-axis outsource the complex work.
Unit economics
Machining gross margin ~75% ($13.5/ft²). A kitchen facade set (~120 ft²): ~$2,160 revenue, ~$1,620 gross profit, ~$324 gross profit per machine-hour.
Risk & damper
The main risk is sales/utilization, not cost. Damper: start on a proven used machine (CapEx a third of new), diversify (facades + fences + jobbing).
