CMM
Coordinate measurement of critical dimensions with GD&T evaluation.
Capabilities: Tolerances, Materials and Finishes
The full specification sheet our engineering team works to — including the numbers we promise in production and the inspection evidence that ships with each lot.
Machining capabilities
Imported 3, 4 and 5-axis machining centers from Germany and Japan, plus turning centers with live tooling and EDM for the features milling cannot reach.
Milling
- 3-axis vertical machining centers
- 4-axis with rotary table
- 5-axis simultaneous and 3+2 indexed
- Pocket depth up to 4× cutter diameter
Turning
- CNC lathes with live tooling and bar feed
- Cross-drilling, milling flats, slots
- Thread milling and single-point threading
EDM and grinding
- Wire EDM for hardened and thin sections
- Sinker EDM for sharp internal corners
- Surface grinding for flatness and finish
Secondary operations
- Heat treatment and stress relief
- Surface finishing and plating
- Laser marking and assembly
Tolerance and quality performance
| Parameter | Standard | Precision |
|---|---|---|
| Linear tolerance | ±0.02 mm | ±0.005 mm |
| Angular tolerance | ±0.5° | ±0.1° |
| Surface roughness | Ra 1.6 µm | Ra 0.4 µm |
| Concentricity | 0.02 mm | 0.01 mm |
| Perpendicularity | 0.02 mm | 0.005 mm |

Surface finishes
Finishes are applied through qualified partners in Shenzhen and inspected before packing. Certification is supplied with each lot on request.
| Finish | Typical materials | Purpose |
|---|---|---|
| Anodizing (Type II / III) | Aluminum | Corrosion resistance, color, wear surface |
| Bead blasting | Aluminum, stainless, titanium | Uniform matte appearance, burr removal |
| Passivation | Stainless steel | Removes free iron, improves corrosion resistance |
| Zinc / nickel plating | Steel, brass | Sacrificial corrosion protection |
| Powder coating | Steel, aluminum | Thick, durable color finish |
| Laser marking | All metals | Part numbers, QR and traceability codes |
Inspection and documentation
The reason buyers in regulated industries stay with us: the paperwork is not an afterthought.
FAI
First article inspection report against a ballooned drawing before batch approval.
Material certs
Mill certificates traceable to the heat and lot number.
Process control
In-process checks plus AQL sampling on finished lots, 99.8% pass rate.
