Custom CNC Machining Services for Precision OEM Parts
SZCROWN provides custom CNC machining services for OEM precision parts, including milling, turning, EDM, grinding, prototypes and production components.

CNC Machining
Precision milling and turning support for custom metal parts, complex housings, prototypes and production runs. Tolerance discussion depends on geometry, material and process requirements.
What This Service Is
CNC machining is used to manufacture custom metal components from engineering drawings, 3D models and defined tolerance requirements. SZCROWN supports prototype validation, DFM review and scalable production for OEM projects.
Custom Metal Parts
SZCROWN supports precision CNC parts, hardware components, custom metal parts, sheet metal parts and non-standard fasteners based on customer drawings.
Stock & Fast Dispatch Notes
Selected sheet metal press-fit hardware and standard hardware may be available from stock for faster dispatch depending on specification and order requirements.
CNC Machining Capability Cards
Built for buyers comparing process fit, material choices and production risk before sending drawings.
CNC Milling
Pockets, slots, complex surfaces, housings and precision plates.
CNC Turning
Shafts, sleeves, pins, threaded parts and round components.
