What is CNC Milling?
CNC milling is a subtractive manufacturing process that uses computer-controlled machines to remove material from a workpiece. Rotating cutting tools create precise features like slots, holes, threads, and complex contours. At XTJ, we provide 3-axis, 4-axis, and 5-axis CNC milling to produce parts ranging from simple flat surfaces to intricate 3D geometries, ensuring versatility for your designs.
Types of CNC Milling Operations at XTJ
We offer a range of CNC milling techniques to suit different project requirements:
Face Milling
Creates flat surfaces and smooth finishes, ideal for large, even areas.
End Milling
Produces slots, pockets, and contours using the side and end of the tool.
Slot Milling
Cuts narrow channels or slots into the workpiece for functional or aesthetic purposes.
Profile Milling
Shapes the outer contours of a part, often used for complex geometries.
Thread Milling
Machines internal and external threads with precision for fasteners and fittings.
Angular Milling
Creates angled features like chamfers or dovetails for specialized components.
Materials and Surface Finishes Supported by XTJ Machining
Varies by material type, generally high hardness. Tool selection and cutting parameters should be based on specific composition, with attention to wear resistance and thermal stability.
Aluminum (e.g., 6061, 7075)
特徴：軽量、良好な熱伝導性、加工が容易で、チップが壊れやすい。工具の粘着を引き起こすことがあるため、適切な冷却と潤滑が必要です。高速ミリングに適しています。
Steel (e.g., stainless, carbon)
特性：高硬度、耐摩耗性があり、加工中に高い切削力と熱を発生させる。硬い工具（例：カーバイド）を用いた低速ミリングが必要。ステンレス鋼は加工硬化を示すことがある。
チタン
特性：高強度、低熱伝導性、加工中に熱が集中しやすく、工具の摩耗を引き起こす。低速切削、高性能工具、十分な冷却が必要。
真鍮
特性：柔らかく加工しやすく、良好な加工性を持ち、切りくずが容易に折れる。高い表面仕上げに適し、高速ミリングに適しており、熱の発生も少ない。
銅
特性：高い熱伝導性、延性があり、加工中に工具の粘着が起こりやすい。鋭利な工具と適切な潤滑が必要。切りくずが長くなることがあるため、切りくずの除去が重要。
ABS
特性：良好な靭性、加工が容易だが、熱による軟化が起こりやすい。溶融やバリを防ぐために切削速度と冷却の管理が必要。
POM（ポリアセタール）
特性：中程度の硬さ、耐摩耗性、自己潤滑性、加工中の安定性、良好な表面仕上げ。熱変形に注意が必要。
PEEK
特性：高温耐性、耐薬品性、高硬度。硬い工具が必要で、高い切削力が発生し、変形防止のため温度管理が必要。
ポリカーボネート
特性：透明で高靭性だが、応力割れが起こりやすい。過熱を避けるため低速切削が必要で、鋭利な工具が求められる。
ナイロン
特性：高靭性、耐摩耗性だが吸湿性があり、加工中に変形しやすい。切削速度の管理が必要で、低速フライス加工に適している。
Carbon Fiber
Characteristics: High strength, lightweight, but very hard. Prone to delamination or burrs during machining. Requires diamond or carbide tools, and dust protection is necessary.
ガラス繊維
Characteristics: High hardness, corrosion-resistant, but abrasive to tools and generates dust during machining. Requires efficient dust extraction and hard tools.
Elevate Your Parts with Advanced Surface Finishing
Enhance the durability, functionality, and aesthetics of your components with XTJ’s range of surface finishing options. Each process is tailored to meet specific performance and design requirements, ensuring your parts not only perform exceptionally but also look their best.
Durable and Versatile Coating for Long-Lasting Protection
Powder coating applies a dry powder—typically a mix of resin and pigment—electrostatically to the part, which is then cured under heat to form a tough, protective layer. This finish is known for its durability and resistance to chipping, scratching, and corrosion.

Uniform Matte Finish for Enhanced Aesthetics
Bead blasting uses small glass beads propelled at high pressure to create a consistent, non-reflective matte finish on the surface of parts. This process removes surface imperfections and provides a clean, uniform texture.
Mirror-Like Finish for Premium Applications
Polishing involves mechanically smoothing the surface of a part to achieve a high-gloss, mirror-like finish. This process enhances both the visual appeal and the tactile quality of the component.
Enhanced Corrosion Resistance for Stainless Steel
Passivation is a chemical treatment that removes free iron from the surface of stainless steel parts, forming a passive oxide layer that significantly improves corrosion resistance.
XTJ’s CNC Milling Capabilities
Multi-Axis Options: 3-axis, 4-axis, and 5-axis milling for simple to complex geometries.
