CNC Machining Services
CNC Milling
From rapid prototyping to custom production runs, take advantage of quality 3-axis, 4-axis, and full 5-axis CNC milling for highly accurate and quality CNC milling products. LN offers quality CNC milling services to help transform your designs into complex geometric shapes.
CNC Turning
Our precision CNC turning lathes provide low-cost parts for simple and complex cylindrical geometries. We also use Live tooling to create precise, complex geometries for features like axial and radial holes, grooves, slots, and flats,which makes us can easily and efficiently produce tight tolerance parts.
Our CNC Machining Standards
| CNC Machining Tolerances and Standards | ||
|---|---|---|
| With precision CNC machining services, LN-Machining is your ideal partner to create precision machined prototypes and parts. Our standard CNC machining tolerances for metals is ISO 2768-f and for plastics is ISO 2768-m. We can also achieve special tolerances as long as you indicate your requirements on your drawing. | ||
