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

  • Qual é a diferença entre uma fresadora CNC e uma fresadora CNC?
    As fresadoras CNC são projetadas para velocidades de corte baixas a moderadas e são comumente usadas para materiais mais macios, como madeira, plástico, espuma e metais não ferrosos, como alumínio. Em contraste, as fresadoras CNC apresentam fusos mais robustos e maior potência, permitindo-lhes cortar materiais mais duros, incluindo aço inoxidável, titânio e compósitos, bem como materiais mais macios. Embora os roteadores CNC sejam normalmente usados ​​para tarefas de usinagem menos precisas e mais simples e possam trabalhar em peças grandes, tornando-os populares em indústrias como marcenaria e sinalização, as fresadoras CNC são adeptas da usinagem de peças complexas e da produção de componentes de alta precisão com tolerâncias restritas. . Eles são comumente empregados nas indústrias aeroespacial, automotiva e de fabricação médica.
  • Qual é a diferença entre corte CNC e fresamento?
    O corte CNC, por meio de métodos como laser, jato de água e corte a plasma, é projetado para fatiar materiais para formar formas ou contornos externos. Este método é especialmente valioso para manusear rapidamente folhas grandes, proporcionando bordas de alta qualidade com rapidez. É uma etapa comum na fabricação de chapas metálicas. Por outro lado, a fresagem CNC é um método mais focado de remoção de material por dentro, removendo material com precisão com ferramentas rotativas para criar formas 3D complexas e recursos detalhados em peças, adequadas para componentes de alta precisão.
  • Quais tipos de ferramentas de corte para fresamento?
    Existem muitos tipos diferentes de ferramentas de corte que podem ser usadas com fresas CNC. As fresas de topo são as ferramentas de fresamento mais comuns. Eles podem cortar ao longo do eixo da ferramenta (axialmente) e ao longo do diâmetro da ferramenta (lateralmente), com vários formatos de extremidade, como quadrado, ponta esférica e raio de canto, para produzir diferentes geometrias. Outras ferramentas de fresamento comuns incluem fresas de facear, que são usadas para criar superfícies planas; cortadores de ponta esférica, ideais para contornos 3D; fresas de chanfro, para fazer bordas chanfradas; e cortadores de cauda de andorinha, usados ​​para cortar ranhuras precisas em cauda de andorinha.
  • O que é fresamento CNC?
    A fresagem CNC é um processo de fabricação subtrativo que emprega máquinas controladas por computador. Envolve o uso de uma ferramenta de corte montada em um fuso giratório para remover material de um bloco, moldando-o na forma desejada.
