JADE-CNC can review aluminum CNC machining, stainless steel machining, copper machining, チタン加工, alloy machining, and related finishing or inspection requirements according to the drawing.
超合金CNC機械加工
High-temperature and corrosion-resistant alloys may be selected for demanding industrial parts when strength, 耐熱性, and inspection requirements justify the machining difficulty. JADE-CNC reviews tooling, cutting strategy, and quality requirements before quotation.
ヒートシンク CNC 加工
Heat sink materials and geometry affect thermal performance, machining cost, 表面仕上げ, そして組み立て. JADE-CNC reviews fins, channels, 平坦度, 材料, and finish requirements before machining heat sink components.
コバール合金 CNC 機械加工
Kovar alloy is used when controlled thermal expansion is important for glass, ceramic, or semiconductor-related assemblies. Drawing requirements, 公差制御, and inspection should be reviewed before machining.
プラスチックCNC機械加工
Engineering plastics such as ABS, アクリル, ポリカーボネート, ナイロン, ピーク, PTFE, and acetal can be used for plastic machining when lightweight, insulating, 透明, chemically resistant, or low-friction parts are required. 材料の安定性, moisture absorption, バリコントロール, 表面仕上げ, and tolerance behavior should be reviewed early.

What JADE-CNC Reviews Before CNC Material Selection
Choosing a CNC machining material is not only about selecting a grade from a list. The right material should match the part function, 加工方法, 公差要件, 表面仕上げ, アプリケーション環境, 検査の必要性.
Material Function
JADE-CNC reviews whether the part needs strength, 低体重, 耐食性, electrical conductivity, 耐熱性, 耐摩耗性, 絶縁, or dimensional stability.
被削性
Different metals and plastics affect tool wear, 切断速度, バリコントロール, surface quality, and machining cost. The machining route should match the material behavior.
Tolerance Stability
Material stress, 壁の厚さ, 熱処理, moisture absorption, and part geometry can affect dimensional stability during and after machining.
Surface Finish Compatibility
陽極酸化処理, メッキ, 不動態化, 研磨, ビーズブラスト, 絵画, and coating requirements should be checked against the selected material and functional surfaces.
Inspection and Traceability
For projects that need reports or material records, JADE-CNC can coordinate dimensional checks, selected feature inspection, 素材確認, and documentation requirements.
Common CNC machining materials include aluminum, ステンレス鋼, 炭素鋼, alloy steel, 銅, 真鍮, チタン, POM, ピーク, PTFE, パソコン, ABS, アクリル, ナイロン, その他エンジニアリングプラスチック.
Start from the part function. 強さ, 重さ, 耐食性, 導電率, 耐熱性, tolerance stability, 表面仕上げ, and inspection requirements should be considered together.
Common aluminum grades include 6061, 7075, 2024, 5052, 6063, and MIC-6 tooling plate. Each grade has different strength, 被削性, 耐食性, and finishing behavior.
Stainless steel is often selected when corrosion resistance, 強さ, 耐摩耗性, or appearance is important. 304 そして 316 are common options for CNC machined stainless steel parts.
Copper and brass are often used when electrical conductivity, 熱伝導率, or stable machining of small turned features is important.
