miniature screws of medical implants

In the era of Industry 4.0, CNC precision parts have become the "hidden champion" of high-end manufacturing. From the turbine blades of space engines to the miniature screws of medical implants, from the metal shells of smartphones to the battery components of new energy vehicles, behind these seemingly tiny parts is the ultimate pursuit of precision, efficiency and reliability in computer numerical control (CNC) technology. 1. What are CNC precision parts?   CNC (Computer Numerical Control), that is, computer numerical control technology, is a method of controlling machine tool processing through digital programming. Unlike traditional manual or semi-automatic machining, CNC technology is able to convert complex design drawings into precise machining instructions, drive the tool to cut the material with micron precision, and finally create a part that meets exacting standards. 2. Application fields of CNC precision parts 1. Aerospace:      - Turbine blades and fuel nozzles need to withstand extreme temperatures and pressures, and CNC machining ensures aerodynamic performance and structural strength.      - Example: Boeing 787 titanium alloy fuselage frame, error less than 0.025mm.     2. Medical Devices      - Artificial joints and surgical instruments require biocompatible and sterile surfaces, and CNC is mirror-grade polished.      - Case in point: Porous structure of orthopedic implants that promote bone growth.     3. Automotive Industry      - Engine block and gearbox gears rely on high-precision meshing, and CNC reduces frictional losses.      - Case study: CNC machined positioning holes in a Tesla integrated die-cast body.     4. Consumer Electronics:      - The middle frame and lens mount of mobile phones need to be lightweight and strong, and CNC milling aluminum alloy has become the mainstream process.        - Example: The Unibody body of the iPhone, which is CNC engraved from a single piece of aluminum.
