Complete Machining
Finish OD/ID turning, flats, holes and threads in one process where geometry allows.
ISO 9001 • IATF 16949 precision manufacturing
SinoCMI provides single-setup turn-mill and multi-tasking machining for complex rotary metal and plastic components. We combine turning, milling, drilling and tapping in one process to reduce clamping, protect concentricity and support fast RFQ, DFM and inspection needs from prototype to production.
Turn-mill machining combines CNC turning and multi-axis milling in one machine. It is built for complex rotary parts that need turning, milling, drilling, tapping, C-axis positioning and Y-axis compound features without moving between machines.
Finish OD/ID turning, flats, holes and threads in one process where geometry allows.
Machining for cross holes, side slots, bosses, flats and angular features.
Handle both sides of the part with automatic transfer to reduce re-fixturing.
Virtual process planning helps reduce risk, access issues and scrap.
Application fit
Turn-mill is a strong choice when a part needs both rotary symmetry and off-center features, or when multiple setups would create tolerance stack-up, higher labor cost or longer lead time.
SinoCMI machines custom turn-mill parts for engineers and procurement teams that need one setup, better geometric control and clean documentation from prototype to production.
Complex fluid passages, threaded ports, bores and sealing surfaces.
Precision rotary parts with milled flats, holes, slots and shoulders.
Parts with internal turning, external threads and milled interfaces.
High-value rotary components with clean edges and tight positional control.
End-effectors, couplings, adapters, mounts and precision mechanism parts.
Lightweight fittings, complex connectors, interface parts and mission hardware.
Material strategy affects stability, chip control, tool life and the final finish. We support production-grade metals, high-performance alloys and engineering plastics with common finishing options.
Multi-axis turn-mill parts often depend on roundness, concentricity, runout and feature relationships. We build the process and inspection plan around the critical dimensions that matter to function.
