What Are Micro‑precision Metal Parts?
Micro‑precision metal parts are miniature metal components engineered with exacting tolerances often measured in micrometers (µm). They are significantly smaller than typical machined parts, yet must meet stricter dimensional accuracy and surface quality standards. Such parts are used in applications where even minor inconsistencies could lead to functional failure.
These components range in size, often from fractions of a millimeter up to a few centimeters, and include pins, shafts, gears, connectors, and housings that must perform reliably under high‑stress conditions. Companies like Shenzhen Xincheng Precision Technology Co., Ltd. specialize in delivering consistent micro‑precision parts to global supply chains.
How Are Micro‑precision Metal Parts Made?
The manufacturing processes for micro‑precision parts require advanced machinery, expert programming, and ultra‑stable environments. Below is an overview of major production methods used in this domain:
| Manufacturing Method | Description | Typical Use Scenarios |
|---|---|---|
| Micro CNC Machining | Computer‑controlled machining of metals with cutting tools smaller than 1mm. | High‑precision shafts, slots, and threaded components. |
| Electrical Discharge Machining (EDM) | Using controlled electrical discharges to erode metal with sub‑micron precision. | Intricate shapes in hard metals and alloys. |
| Laser Micro‑machining | Laser ablation to remove material without physical tool contact. | Thin films, tiny holes, and surface texturing. |
| Micro Grinding | Using ultra‑fine abrasives to achieve fine finishes. | Polishing and fine shape adjustments. |
| Precision Stamping | High‑speed die stamping of thin metal sheets. | Mass production of small shims, clips, contacts. |
These processes are selected based on part geometry, material properties, and tolerance requirements. Precision manufacturers like Shenzhen Xincheng Precision Technology Co., Ltd. combine multiple methods to ensure optimal part performance.
Why Do Industries Need Micro‑precision Metal Parts?
