Surface Finishes for CNC Milled Parts

While milling achieves high precision, it can leave behind tool marks. Opting for our high-quality surface finishing can effectively remove these imperfections, significantly improving the visual appeal of the components. Furthermore, these finishes may provide enhanced durability and additional resistance for your CNC milled parts.

Name Applicable Materials Color Surface Feature Tolerances
As-machined Metals, Plastics Tool marks visible Tolerances are not affected
Bead blastingMetals, Plastics Uniform, matte, or satin Typically not affected except for specific features
Polishing  Metals Smooth and often reflective Met after polishing
Brushing Metals Unidirectional satin Met after brushing
Powder coating  Primarily metals such as Steel, Stainless steel, Aluminum, Brass, and Copper Custom Smooth, matte to high gloss texture Met after powder coating
Painting Metals, Plastics Custom Smooth to textured for anti-slip or aesthetic properties Met after painting
Chromate conversion coating Aluminum Clear, gold, olive drab, black Slight roughness or maintain the pre-treatment texture Met after coating
Black oxide Stainless steel, Alloy steel, Tool steel, Mild steel,Copper Black Maintains the original surface texture with a matte black finish Met after black oxide
Electroless nickel plating Metals, Plastics SilverySmooth with uniform thickness Met after electroless nickel plating
Electroplating Primarily for metallic substrates Characteristic color depending on plating metals Smooth to textured Met after electropolishing
Anodizing type II Aluminum Clear, black, blue, red, gold or any RAL code or Pantone number Changes are minimal, remains very close to the pre-anodized texture Met after anodizing
Anodized type III Aluminum Nature, dark grey , black or other colors Smooth to textured Met after anodizing
Passivation Stainless steel and other corrosion-resistant alloys Maintains the original surface texture Met after passivation

The details provided here are typical characteristics of these surface finishing processes. However, actual tolerances and results may vary based on the specific procedures, equipment used, and material conditions. For custom surface finishes, please contact Chiggo.

Tolerances of CNC Milling

At Chiggo, we're equipped to produce milled parts that meet your specific tolerance requirements, even tight tolerances down to ±0.01mm. If these are not detailed in your drawings, we will follow the ISO 2768 standards for both machined plastic and metal parts. Moreover, we will recommend the most appropriate tolerances for your  particular application, optimizing cost for the desired quality.

CNC Machining FAQs

  • ¿Cuál es la diferencia entre una fresadora CNC y una fresadora CNC?
    Las enrutadores CNC están diseñadas para velocidades de corte de bajas a moderadas y se usan comúnmente para materiales más blandos como madera, plástico, espuma y metales no ferrosos como el aluminio. Por el contrario, las fresadoras CNC cuentan con husillos más robustos y mayor potencia, lo que les permite cortar materiales más duros, incluidos acero inoxidable, titanio y compuestos, así como otros más blandos. Mientras que las fresadoras CNC se utilizan normalmente para tareas de mecanizado más simples y menos precisas y pueden funcionar en piezas de trabajo grandes, lo que las hace populares en industrias como la carpintería y la rotulación, las fresadoras CNC son expertas en mecanizar piezas complejas y producir componentes de alta precisión con tolerancias estrictas. . Se emplean comúnmente en las industrias de fabricación aeroespacial, automotriz y médica.
  • ¿Cuál es la diferencia entre corte y fresado CNC?
    El corte CNC, mediante métodos como el corte por láser, chorro de agua y plasma, está diseñado para cortar materiales para formar formas o contornos externos. Este método es especialmente valioso para manipular rápidamente hojas grandes y generar bordes de alta calidad con rapidez. Es un paso común en la fabricación de chapa. Por otro lado, el fresado CNC es un método más centrado en la eliminación de material desde dentro, eliminando material con precisión con herramientas giratorias para crear formas 3D complejas y características detalladas en piezas, adecuadas para componentes de alta precisión.
  • ¿Qué tipos de herramientas de corte para fresar?
    Existen muchos tipos diferentes de herramientas de corte que se pueden utilizar con fresadoras CNC. Las fresas finales son las herramientas de fresado más comunes. Pueden cortar a lo largo del eje de la herramienta (axialmente) y a lo largo del diámetro de la herramienta (lateralmente), con varias formas de extremo, como cuadrado, punta esférica y radio de esquina, para producir diferentes geometrías. Otras herramientas de fresado comunes incluyen fresas frontales, que se utilizan para crear superficies planas; cortadores de punta esférica, ideales para contornear en 3D; fresas de chaflán, para hacer bordes biselados; y cortadores de cola de milano, utilizados para cortar ranuras de cola de milano precisas.
  • ¿Qué es el fresado CNC?
    El fresado CNC es un proceso de fabricación sustractivo que emplea máquinas controladas por computadora. Implica el uso de una herramienta de corte montada en un eje giratorio para extraer material de un bloque y darle la forma deseada.
