Product Description

Products Features
🎯 Ultra High Precision

By using multi-axis CNC machines (such as 5-axis machining centers), precise tolerances of ±0.005mm can be achieved. In some cases, the precision even reaches 0.0025mm. A strict quality inspection system ensures key dimensions meet the requirements of high-end fields such as healthcare and aerospace.

🔩 Material Diversity

Supports processing of various materials including stainless steel, aluminum alloy, titanium alloy, copper and engineering plastics. Surface treatment processes (such as passivation) can be selected according to requirements to enhance performance.

⚙️ Complex Structure

By using multi-axis linkage technology, complex geometric shapes can be processed — such as those for medical devices and components of unmanned aerial vehicles.

🏭 Industry Compatibility

Widely applied in fields such as precision instruments, automobiles, communication equipment and automated machinery.

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 Flatness ≤ 0.1 μm/100mm The silicon wafer carrier is processed using a precision grinding method on a granite base.
  • 5G Base Station Filter Cavity Accuracy ±0.01mm Complex internal cavity structure is achieved through slow wire electrical discharge machining.
🏥 (2) Medical Devices and Biotechnology Engineering
  • Surgical Robot Joint Mating Clearance ≤ 10 μm Made of 316L stainless steel, precisely processed, ensuring smooth movement.
  • Implantable Device Ra ≤ 0.2 μm The surface of the artificial joint needs to be mirror-polished to reduce tissue friction. The material is cobalt-chromium alloy.
🚗 (3) Automobile and New Energy Field
  • Electric Drive System DIN 6 Level Accuracy The motor shaft is made of carburized steel 20CrMnTi, with gear shape accuracy reducing transmission noise.
  • Hydrogen Fuel Cell Bipolar Plate Flow Channel Tolerance ±0.02mm Achieved through ultra-precise stamping for micrometer-level sealing.
✈️ (4) Aerospace and Defense Industry
  • Aircraft Engine Components Geometric Tolerance ≤ 5 μm Ra ≤ 0.4 μm Turbine blades and fuel nozzles are formed through five-axis CNC processing.
  • Missile Guidance System Micrometer-Level Coaxiality Inertial navigation components (e.g., gyroscope mounts) are precisely turned. Materials are mostly titanium alloy TC4.
