CNC Machining parts are used in the following fields

I. Automotive Manufacturing Industry

Key Part Examples:

Engine System: Cylinder heads, crankshafts, camshafts, fuel injector bases.

Chassis System: Steering knuckles, control arms, brake calipers, wheel hub bearing seats.

New Energy Vehicle (NEV)-Specific Parts: Motor rotors/stator cores, battery pack brackets (aluminum alloy lightweight structure), internal conductive terminals of charging piles.

II. Aerospace and National Defense Industry

Key Part Examples:

Aero-Engine: Turbine blades (complex curved surfaces, superalloy material), combustion chamber casings, fuel control system valves.

Airframe and Avionics: Aircraft frame connectors (titanium alloy thin-walled parts), radar radome brackets, satellite attitude adjustment mechanism parts.

National Defense Equipment: Precision gears for missile guidance systems, parts of tank gun recoil mechanisms, UAV airframe frames (carbon fiber composite material processing).

III. Industrial Equipment and Automation Industry

Key Part Examples:

Machine Tools Themselves: Spindle sleeves, guideway sliders, ball screw nuts (high-precision transmission parts).

Automated Robots: Robot arm joint bearing seats, reducer gears (core parts of RV reducers), end effector clamps.

General Equipment: Water pump/compressor impellers, hydraulic valve cores, printing machine roller shafts.

IV. Medical Device Industry

Key Part Examples:

Surgical Instruments: Orthopedic surgical drills (titanium alloy material, to avoid allergies), laparoscopic forceps tips.

Diagnostic Equipment: Rotating brackets for CT/MRI scanners (processed from low magnetic interference materials), sample detection chambers for hematology analyzers.

Implantable Devices: Artificial joint prostheses (processed from titanium alloy/ceramic composite materials, requiring conformity to the curved surface of human bones), heart stent connectors (ultra-thin-walled tube processing).

V. Electronics and Consumer Electronics Industry

Key Part Examples:

Consumer Electronics: Mobile phone middle frames (precision milling of aluminum alloy/stainless steel), laptop cooling fan blades, metal grilles for wireless earphones.

Industrial Electronics: Sensor housings (processed from waterproof and anti-electromagnetic interference materials), PCB board fixing brackets, connector pins (precision turning of brass).

Technical Requirements: Parts are small in size (usually ranging from a few millimeters to tens of millimeters), with a precision requirement of ±0.01~0.03mm, and appearance requirements (e.g., no scratches, high-gloss chamfers) must also be met.

VI. New Energy and Clean Energy Industry

Key Part Examples:

Photovoltaics (PV): Heat sinks for PV inverters (precision milling of aluminum alloy to enhance heat dissipation efficiency), solar bracket connectors.

Wind Power: Wind turbine main shaft bearing seats (CNC boring and milling of large cast steel parts), gearbox parts inside nacelles.

Energy Storage: Energy storage battery module brackets (processed from high-strength plastic or aluminum alloy), internal copper bars of charging piles (high-precision cutting and bending).

VII. Other Industries

Mold Manufacturing: Mold cores and cavities for injection molds and stamping molds (high-precision CNC milling + EDM machining to ensure mold precision).

Translation Notes:

Industry Terminology Accuracy: Core terms follow international industrial standards (e.g., “RV reducer” for “RV reducer”, “EDM machining” for “EDM processing” (Electrical Discharge Machining), “superalloy” for “high-temperature alloys”).

Structural Consistency: Maintained the hierarchical structure of the original Chinese (industry → key parts → supplementary details) using headings and bullet points for readability, consistent with English technical documentation norms.

Material & Process Clarity: Supplementary descriptions in parentheses (e.g., “aluminum alloy lightweight structure”, “low magnetic interference materials”) are directly translated to retain technical context, avoiding ambiguity for professional readers.
