Inspection-Grade Precision
Understanding Precision CNC Machining
Material removed, to a number you can measure
Precision machining removes material from a workpiece or blank to create a high-accuracy component with extremely controlled dimensional requirements. It relies on Computer Numerical Control (CNC) — an automated machining technology that creates consistent, dimensionally accurate components driven by g-code.
Our CNC machines are configured for holding 0.005 in, achieving tolerances where traditional machining simply fails. It describes the workflow of choice for dimensionally dimensionally controlled components in aerospace and electronic manufacturing, where every thousandth of an inch matters.
Nelotiv applies the most advanced production tools — CAD to interpret your detailed drawings, and CAM to sequence the CNC operations in the most efficient and cost-effective way possible.

Nelotiv CNC turning service specifically caters to any cylindrical component and round workpiece with controlled dimensional specifications. Our turning house crafts feature-rich geometries with speed and efficiency.
Multi-Axis (4 & 5)
Multi-Axis: 4 & 5-Axis Milling
Contours on a single workpiece, no re-fixturing
For rapid prototyping and elevated-dimensional control machining, our machine inventory holds multi-axis CNC machines that create contours and features on a single workpiece without changing fixtures. 5-axis milling reduces waste and is highly sought for prototype development.
