CNC Machining Services
overview
What are precision machining services?
NIG’s Machining Services provide specialized outsourcing for your manufacturing needs. Leveraging cutting-edge CNC technology, we deliver precise, high-quality parts while expertly managing and optimizing every step of the production process.
We offer high-precision CNC metal processing based on your drawings or samples, delivering customized prototypes and products. Our services include CNC turning, milling, grinding, electrical discharge machining, wire EDM, laser engraving, and more. We work with a range of materials, including stainless steel, titanium alloys, aluminum alloys, and zirconium, and are equipped to handle all types of surface treatments.
- 3-axis and 4-axis Milling
- 2-axis Turning
- Wire-cutting and Die-sinking (EDM)
We handle a wide range of post-processing tasks, from surface finishing to assembly. Our aim is to offer comprehensive, integrated manufacturing services that minimize overhead costs while enhancing quality control and reducing lead times.
- Anodizing
- Alodine Coating
- Powder Coating and Spray Painting
- Plating
- Heat Treatment
(outsourcing to outside partners.)
