Custom CNC Machining for OEM Metal Parts
IN-HOUSE MACHINING
Custom CNC machining for build-to-print OEM metal parts, prototypes, production components and projects that combine machined parts with sheet metal fabrication or complete assembly.

Best-Fit CNC Projects
OEM Precision Parts
Build-to-print components for automation equipment, industrial machines, fixtures and mounting systems.
Turned & Shaft Components
Shafts, bushings, spacers, threaded parts and other rotational components defined by the customer drawing.
Mixed-Process Assemblies
Machined parts combined with fabricated sheet metal, welding, hardware, finishing and final assembly.
CNC Milling & Turning
Features can include holes, slots, threads, faces, bores and geometry defined by customer drawings. Common materials reviewed include aluminum, stainless steel, carbon steel, copper and brass.
What We Need to Quote
Drawing & Revision
2D/3D drawing with revision level and any datum, thread or fit requirements that are critical.
Material & Quantity
Material grade and prototype, pilot or repeat-production quantity.
Tolerance & Inspection
Identify critical tolerances, surface finish and any inspection record requirements before production.
Common In-House Size Range
Common in-house machining size is approximately 850 mm. Larger or special parts are reviewed by material, geometry, tolerance and quantity for in-house, partner-supported or hybrid manufacturing rather than being accepted automatically.
Inspection
Available inspection tools include calipers, micrometers, height gauges, thread and plug gauges, optical measurement, hardness testing and roughness testing. LIUMAI does not claim an in-house CMM; special inspection requirements should be stated on the RFQ.
Sheet Metal + CNC in One Project
LIUMAI can combine precision machined components with fabricated sheet metal, welding, hardware, finishing and final assembly, reducing supplier handoffs for equipment manufacturers and OEM procurement teams.
Typical Products & Applications
Mounting & Interface Parts
Adapters, shafts, spacers, threaded parts, mounting plates and precision interfaces for OEM equipment.
Lighting & Equipment Components
Machined housing features and structural components for professional lighting and industrial equipment programs.
Mixed-Process Assemblies
CNC parts combined with sheet metal, welding and hardware for automation, automotive and other OEM applications.
PROCUREMENT FAQ
Questions Buyers Commonly Ask
What CNC equipment is available in-house?
LIUMAI currently has 10 CNC machining centers or milling machines, 10 CNC lathes, one wire cutting machine, plus drilling and tapping equipment.
What is the common in-house machining size range?
