Kovar alloy CNC machining material for precision 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.

Plastic CNC machining materials for custom parts

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.

One-stop CNC machining material and finishing support

ワンストップ CNC 加工ソリューション

For projects that need machining, 仕上げ, 検査, および組み立てサポート, JADE-CNC coordinates the manufacturing workflow so drawings, 材料要件, 表面仕上げ, quality checks, and delivery expectations stay aligned.

Material Selection Reference

CNC加工材料選択ガイド

Material selection affects machining cost, 寸法安定性, 表面仕上げ, 強さ, 重さ, 耐食性, 導電率, そして最終検査. JADE-CNC can review material options based on the drawing, part function, production quantity, 仕上げ要件, and application environment.

The values below are typical references for early material comparison. Final material choice, equivalent grade, finish compatibility, and inspection requirements should be confirmed during RFQ and engineering review.

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.

CNC material function review for machined parts

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.

CNC material machinability review for custom parts

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 review for CNC machining materials

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 review for CNC materials

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 review for CNC machined materials

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.

はい. POM, ピーク, PTFE, パソコン, ABS, アクリル, ナイロン, and other plastics can be CNC machined, but material movement, バリコントロール, moisture absorption, and tolerance behavior should be reviewed.

はい. 材料費, 被削性, 工具の摩耗, setup difficulty, 仕上げ要件, and inspection needs all affect CNC machining cost.

はい. 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 results depend on material grade, 表面状態, 幾何学, およびマスキング要件.

Customer-supplied materials can be reviewed when material grade, ストックフォーム, 認証の必要性, 取り代, and handling requirements are clear.

Please send 3D CAD files, 2D図面, material grade or preferred options, アプリケーション環境, 公差メモ, 表面仕上げ要件, 量, 検査の必要性.
