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:
01 Electronic and Semiconductor Equipment
Lithography Machine Components
Flatness ≤ 0.1 μm/100mm

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 Accuracy ±0.01mm

Cavity processing accuracy ±0.01mm, complex internal cavity structure is achieved through slow wire electrical discharge machining.

02 Medical Devices and Biotechnology Engineering
Surgical Robot Joint
Mating Clearance ≤ 10 μm

Made of 316L stainless steel, precisely processed, with a mating clearance of ≤ 10 μm, ensuring smooth movement.

Implantable Device
Surface Ra ≤ 0.2 μm

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.

03 Automobile and New Energy Field
Electric Drive System
Gear Accuracy DIN 6 Level

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 Tolerance ±0.02mm

Flow channel depth tolerance ±0.02mm, achieved through ultra-precise stamping for micrometer-level sealing.

04 Aerospace and Defense Industry
Aircraft Engine Components
Geometric Tolerance ≤ 5 μm

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
Titanium Alloy TC4

The inertial navigation components (such as gyroscope mounts) need to ensure micrometer-level coaxiality through precise turning. The materials are mostly titanium alloy TC4.
