Our CNC milling capabilities support complex custom parts with tolerances down to ±0.01 mm, delivering precise features and consistent quality from prototypes to production runs.
Multi-axis CNC milling — JeaSnn provides 3-axis, 4-axis, and 5-axis CNC milling for custom metal and plastic parts. We select the appropriate machining method according to your part geometry, critical features, tolerance requirements, material, and production quantity.
3-axis CNC milling is suitable for parts with accessible features on a single face or a limited number of sides. It efficiently produces flat surfaces, holes, slots, pockets, threads, and standard mechanical features for prototypes and production parts.
4-axis CNC milling adds controlled workpiece rotation, allowing features on multiple sides to be machined with fewer setups. It is well suited for parts with holes, slots, flats, grooves, or repeated features positioned around the component.
5-axis CNC milling is used for complex parts with multiple machined faces, angled surfaces, deep features, and critical geometric relationships. Machining more features in fewer setups helps maintain alignment between surfaces and reduces errors caused by repeated repositioning.
Quality control is integrated throughout our CNC machining process, from incoming material inspection and in-process checks to final verification before shipment. Our 15-person QC team uses CMMs, 2.5D vision measuring systems, hardness testers, and other precision measuring tools to inspect critical dimensions and verify that finished parts meet customer drawings and technical specifications before delivery.
CNC milling is widely used in the aerospace industry to manufacture components such as engine parts, turbine blades, brackets, and structural components with complex geometries and tight tolerances.
In the automotive industry, CNC milling is used for producing engine components, transmission parts, suspension components, and custom prototypes with precise dimensions and high-quality finishes.
CNC milling is used to produce printed circuit boards (PCB), connectors, housings, and other electronic components with precise features, tight tolerances, and high-quality finishes.
CNC milling is ideal for rapid prototyping and product development, allowing designers and engineers to quickly create prototypes of new products and iterate designs based on testing and feedback.
CNC milling is used in custom fabrication shops to produce one-off or small-batch parts, components, and assemblies for various industries, including architectural, artistic, and decorative applications.
