CNC Machining Services
CNC machining remains one of the most reliable methods for producing precise, repeatable metal and plastic components. Sourcima connects your engineering or procurement team with verified machining partners worldwide, offering consistent part quality, tight tolerances, and scalable production capacity.
Whether you're validating a prototype, preparing for EVT/DVT/PVT, or scaling into production, our network supports every stage of hardware development.
CNC Machining Capabilities
Comprehensive machining services for any complexity
3-Axis CNC Machining
3-axis CNC milling is the most widely used machining method and is ideal for producing flat surfaces, pockets, drilled or tapped holes, and general prismatic geometries. It offers reliable accuracy for straightforward mechanical parts with standard tolerances around ±0.1 mm, while precision suppliers can achieve ±0.05 mm for features that require tighter control. This makes 3-axis milling suitable for brackets, plates, housings, fixtures, and everyday functional components used throughout hardware development and production.
4-Axis CNC Machining
4-axis CNC milling introduces a rotational axis, allowing the part to be machined around multiple faces without manual repositioning. This reduces tolerance stack-up and improves alignment between critical surfaces, giving it a standard tolerance capability of around ±0.05 mm, with precision shops achieving ±0.02–0.03 mm depending on geometry. It is commonly used for housings with side features, alignment-critical components, parts with indexed or radial patterns, and medium-complexity production components where cross-face accuracy matters.
5-Axis CNC Machining
5-axis CNC milling enables machining of complex shapes, steep angles, deep pockets, and multi-surface geometries in a single setup, offering the most advanced capability of the three processes. Standard achievable tolerances typically fall within ±0.02–0.05 mm, while high-end suppliers can hold ±0.005–0.01 mm for precision-critical parts. This process is used extensively for aerospace brackets, medical and surgical components, robotics assemblies, and complex prototypes or production parts requiring tight tolerances and exceptional repeatability
