II. Core Capabilities for Micro Precision Machining
1️⃣ Equipment & Machine Configuration
To ensure stability and repeatability for micro parts, Yong Yi Technology is equipped with:
- High-speed CNC machining centers (spindle speed 20,000–40,000 rpm)
- High-rigidity linear guides and roller ball screws
- Dedicated micro-tool holders (Shrink Fit / Hydraulic Chuck)
- 5-axis machining capability to minimize repositioning errors
Core Objective:
Complete machining in a single setup to eliminate cumulative tolerances.
2️⃣ Dedicated Process Design for Micro Parts
In micro machining, Yong Yi Technology prioritizes stability and repeatability rather than speed:
- Optimized machining sequence (rigidity first, precision later)
- Low cutting force strategies (micro depth of cut / micro feed rate)
- Thermal compensation and machine temperature stability control
- Dedicated fixtures and vacuum clamping systems
Key Focus Areas:
- Deformation control
- Burr management
- Edge quality and surface integrity
3️⃣ Material Processing Capability
Yong Yi Technology supports a wide range of materials for micro precision components:
Metals
- Stainless steel (SUS304 / 316 / 420)
- Aluminum alloys (6061 / 7075)
- Copper alloys and brass
- Titanium (small batch, high precision)
Engineering Plastics
- PEEK
- POM
- PET
- PTFE (special fixtures and applications)
III. Quality Control & Inspection
Measurement & Inspection Systems
To meet European and semiconductor equipment standards, Yong Yi Technology implements:
- Optical / micro vision measurement systems
- High-precision Coordinate Measuring Machines (CMM)
- Surface roughness (Ra) inspection
- First Article Inspection (FAI) and In-Process Quality Control (IPQC)
Documentation Available

✔ Ideal for European equipment manufacturers with established designs
2️⃣ DFM / DFA Co-Development Support
- Manufacturability analysis for micro precision parts
- Optimization of:
- Tolerance allocation
- Machining strategy
- Cost and yield
✔ Allowing customers to focus on core technologies while Yong Yi handles manufacturing execution
3️⃣ Module & Sub-System OEM
- Multi-part integrated machining
- Surface treatments (Anodizing / Passivation / PVD)
- Pre-assembly and functional testing
✔ Delivered ready for direct equipment integration
4️⃣ Long-Term Serial Production & Export OEM
- Prototype → small batch → stable mid-volume production
- Batch control and revision management
- Export support for Europe, USA, and Japan
