¿Qué es el Fresado CNC?
El fresado CNC es un proceso de mecanizado sustractivo donde herramientas de corte rotativas controladas por computadora eliminan material de una pieza sólida. Unlike turning — which spins the part — milling spins the tool and moves it across a stationary or indexed workpiece along multiple linear and rotational axes.
3-axis milling moves the cutter in X, Y and Z — sufficient for the majority of prismatic features: flat surfaces, pockets, slots and drilled holes. It is the most cost-effective approach for parts where all features are accessible from one face or a small number of setups.
5-axis simultaneous milling adds two rotational axes (A and B, or A and C), letting the spindle approach the workpiece from virtually any angle in a single clamping. This eliminates repositioning errors and is essential for compound-curve aerospace surfaces, medical bone plates, and turbomachinery components. Learn more on our dedicated 5-axis page.
Choose 3-axis for flat or simply stepped geometry. Choose 4- or 5-axis when your part has compound angles, undercuts, or when you need to minimize setups to hit tight positional tolerances across multiple faces.
Tipos de Fresado CNC
Operamos centros de fresado CNC de 3, 4 y 5 ejes. La elección correcta depende de la geometría de la pieza, el tamaño del lote y la tolerancia requerida.
Fresado 3 Ejes
The workhorse of CNC milling. Three linear axes (X, Y, Z) handle the vast majority of prismatic parts — housings, brackets, plates, and blocks with flat or gently contoured surfaces.
- Standard tolerance ±0.01mm
- Flat & contoured surfaces
- Pockets, slots & through-holes
- Max part 600 × 400 × 300 mm
Ideal for: brackets, enclosures, plates, jigs and fixtures
Fresado 4 Ejes
A rotary A-axis added to 3-axis movement. Parts can be indexed or continuously rotated during cutting, eliminating secondary setups for features around a cylindrical or complex profile.
- Rotational features in one setup
- Complex profiles & cams
- Reduced fixturing cost
- Excellent for shaft-style parts
Ideal for: cams, impeller blanks, manifolds with radial features
Fresado 5 Ejes
Simultaneous 5-axis movement lets the cutter approach from any direction. Complex compound curves, undercuts, and tight cavities are cut in a single setup — reducing errors and cycle time.
- Achievable tolerance ±0.001mm
- Aerospace & medical geometry
- Single-setup complex parts
- Undercuts & compound curves
Ideal for: turbine blades, medical implants, aerospace structural parts

Materiales que Mecanizamos
Tenemos en stock y mecanizamos 50+ metales y plásticos de ingeniería. Materiales de fresado CNC comunes:
Acabados Superficiales
Todos los acabados superficiales disponibles internamente. El tiempo de entrega y el costo dependen del proceso.
Tal como Mecanizado
Ra 1.6–3.2 μm direct off the machine. Clean, functional surfaces with visible tool marks.
Anodizado (Tipo II y III)
Electrochemical oxide layer on aluminum. Type II decorative; Type III hard for wear resistance.
Anodizado Duro
Type III anodizing to 25–125 μm. Excellent hardness (60–70 HRC equivalent) and dielectric properties.
Granallado
Uniform matte texture, Ra 0.8–2.0 μm. Removes machining marks and improves aesthetics.
Pintura en Polvo
Durable polymer finish in any RAL/Pantone color. Impact and corrosion resistant.
Electropulido
Electrochemical surface smoothing. Reduces Ra by 50%, ideal for stainless steel medical parts.
Niquelado
Electroless or electrolytic nickel. Corrosion resistance, solderability, or as undercoat for chrome.
Grabado Láser
Permanent part marking — serial numbers, logos, QR codes. No mask or ink required.
Pautas de Diseño para Fresado CNC
Seguir estas pautas le ayuda a obtener presupuestos precisos y garantiza que sus piezas sean fabricables.
- Minimum wall thickness 0.5 mm for metals, 1.0 mm for plastics — thinner walls vibrate during cutting and can deflect.
- Inside corner radius ≥ 1/3 of cavity depth — end mill diameter must fit the corner radius; design accordingly.
- Avoid deep narrow slots (depth > 6× width) — tool deflection and chip evacuation become critical beyond this ratio.
- Specify surface finish Ra only where functionally required — unnecessary finishing callouts add cost and lead time.
- Add draft to vertical walls only if needed for function — draft is for molding, not machining; omit unless necessary.
- Provide a 2D drawing for GD&T callouts and tight tolerances — model alone cannot convey datum references or geometric tolerances.

Need turning too? If your part has both milled features (pockets, flats, cross-holes) AND a turned diameter or threaded shaft, run it through our combined milling-and-turning shop instead — one quote, one setup, tighter inter-feature tolerance.
