Yumei offers 3-axis, 4-axis, and 5-axis CNC milling to meet a wide range of manufacturing needs,This multi-axis CNC machining capability allows us to produce precision parts with tight tolerances and superior surface finishes, supporting prototypes, small batches, and mass production.
We provide high-precision CNC turning for simple medical parts, including bone screws & orthopedic fasteners,surgical instrument shafts & handles,fluid control components,implant components,dental tool parts.Our CNC turning capabilities support aluminum, stainless steel, titanium and medical-grade plastics
Mill-turn machining provides an integrated solution for producing complex rotational-plus-milled components in a single setup. This technology is ideal for parts requiring both precision turning and multi-surface milling, such as surgical instrument & orthopedic implant components and dental implant hardware.
By combining milling and turning cycles, mill-turn machining improves tolerance stability, geometric accuracy, surface finish, and reduces cycle time—supporting both high-performance and cost-efficient OEM production.
Swiss CNC machining is ideal for producing small, high-precision rotational components that require ultra-tight tolerances and excellent concentricity.
Swiss turning excels in machining long, slender, micro-sized, and complex geometry parts while maintaining micron-level accuracy.
Our sheet metal fabrication capabilities include laser cutting, CNC bending, TIG/MIG welding,assembly and surface treatments for steel,aluminum and stainless steel materials,we deliver high quality sheet metal parts for medical industry. Ideal for prototypes, small batches, and scalable mass production.
