Industry-Specific Parts Produced by CNC Turning
Aerospace & Aviation
Critical mission components include turbine and jet engine parts, structural fittings, landing gear parts, and complex fluid fittings
Medical & Healthcare
High-precision components such as surgical instruments, orthopedic and dental implants, and connectors for medical devices
Hydraulic & Pneumatic
Essential fluid power system parts like connectors, sockets, pistons, housings, couplings, and flanges
Automotive & New Energy Vehicle (NEV)
Parts for engines (like crankshafts), transmission components, braking and suspension parts. For NEVs, this extends to components for lightweight battery housings and motor systems
Electronics & Semiconductor
Small, high-accuracy micro-structural components like connectors, housings, pins, and shafts for electronic devices
Energy (Wind, Solar, Oil & Gas)
Robust components for harsh environments, including wind rotating mechanisms, turbine blades, solar frames and housings, and durable parts for oil and gas drilling and valve systems
Robotics & Automation Equipment:
Moving and structural parts requiring tight tolerances for smooth operation, such as shafts and pins
Consumer Electronics & Home Appliances
Durable, high-precision components for power tools, camera drones, home appliances, and even beauty devices
Mold & Tooling
While primary mold-making often uses other processes, CNC turning is used to create precision component parts for the injection molds themselves, such as cores, pins, and other cylindrical features
