Machining and Surface Treatment of Display Micro Screws

2026,07,30
Machining: Cutting temperature for Display Micro Screws must be controlled to prevent overheating and material softening.

Surface Treatment: Nitriding (increasing surface hardness to HV800-1000) and PVD coating (such as TiN/TiAlN, hardness HV1500-2000) can significantly extend the lifespan of Display Micro Screws.
Strict control of processing parameters (temperature, time, gas composition) is required to ensure the depth and hardness of the treated layer meet standards.
100% hardness testing of key components is required before Display Micro Screws leave the factory; data must be recorded and archived.
Sampling inspection can be conducted during mass production to ensure compliance with design requirements.
Any abnormal data must be traced back to its cause (e.g., deviations in heat treatment parameters, material defects) and adjustments made promptly.
