Application Fields
Precision machined parts, with their micrometer-level precision and the ability to process complex geometries, play a crucial role in multiple high-tech fields. The core applications of these parts are as follows:
💡
(1) Electronic and Semiconductor Equipment
🔬
Lithography machine components: The silicon wafer carrier needs a flatness of ≤ 0.1 μm/100mm, and it is processed using a precision grinding method on a granite base.
📡
5G base station filter: Cavity processing accuracy ±0.01mm, complex internal cavity structure is achieved through slow wire electrical discharge machining.
🏥
(2) Medical Devices and Biotechnology Engineering
🦾
Surgical robot joint: Made of 316L stainless steel, precisely processed, with a mating clearance of ≤ 10 μm, ensuring smooth movement.
🦴
Implantable device: The surface of the artificial joint needs to be mirror-polished (Ra ≤ 0.2 μm) to reduce tissue friction. The material is cobalt-chromium alloy.
🚗
(3) Automobile and New Energy Field
⚡
Electric drive system: The motor shaft is made of carburized steel 20CrMnTi, with gear shape accuracy reaching DIN 6 level, reducing transmission noise.
🔋
Hydrogen fuel cell bipolar plate: Flow channel depth tolerance ±0.02mm, achieved through ultra-precise stamping for micrometer-level sealing.
🚀
(4) Aerospace and Defense Industry
✈️
Aircraft engine components: Such as turbine blades and fuel nozzles need to meet geometric tolerances of ≤ 5 μm, surface roughness of Ra ≤ 0.4 μm. Complex curved surfaces are formed through five-axis CNC processing.
🎯
Missile guidance system: The inertial navigation components (such as gyroscope mounts) need to ensure micrometer-level coaxiality through precise turning. The materials are mostly titanium alloy TC4.
