CNC Machining Services for Custom Metal Parts
Likai Metal is a custom CNC machining manufacturer in Yancheng, China, serving industrial OEMs across North America and Europe. We run 3-, 4-, and 5-axis machining centers and CNC lathes to produce precision metal parts directly from your drawings, samples, or 3D files.
Ready to request a CNC machining quote? Send us your STEP or PDF drawings, material grade, quantity, tolerance requirements, surface finish notes, and any critical inspection points. Our team can review your files, confirm machining feasibility, and reply with a practical quotation. Contact Likai Metal to send your drawings.
Likai Metal provides CNC machining services for custom OEM metal parts, including machined components, shafts, housings, brackets, flanges, mounting blocks, and precision machinery parts. We support drawing-based manufacturing with attention to material selection, tolerance requirements, surface finish, inspection, and repeatable batch production.
For CNC machining projects, buyers can provide 2D drawings, STEP files, material grade, tolerance notes, surface finish requirements, expected quantity, and critical inspection points. Clear technical information helps us review machining feasibility, choose the right process, estimate production difficulty, and prepare a more accurate quotation. Send us your drawings and requirements to review CNC machining feasibility before production.
From prototypes to production runs, we machine aluminum, stainless steel, carbon steel, brass, copper, and engineering plastics, holding the tolerances specified on your drawings, with inspection on every order.
Our CNC Machining Capabilities
- 3, 4, and 5-axis CNC milling for housings, brackets, and complex parts
- CNC turning for shafts, flanges, bushings, fittings, and threaded components
- Prototype machining and full production runs
- In-house secondary operations: drilling, tapping, deburring, threading
- Surface finishing: anodizing, powder coating, plating, and polishing
Materials We Machine
Aluminum, stainless steel, carbon steel, brass, copper, and engineering plastics such as POM, nylon, and ABS. Other materials available on request.
Quality & Inspection
We machine to the tolerances and specifications on your drawings and focus on consistent quality. New parts can be supplied with an inspection report, and we provide first-article inspection for new production where required.
Typical Applications
Industrial equipment housings and brackets, fittings, automation components, machinery parts, fitness equipment hardware, and custom OEM components for build-to-print manufacturers.
Lead Times
Lead times depend on part complexity, quantity, and finishing requirements. We confirm a delivery schedule for your specific order together with every quotation.
Common CNC Machined Parts
Our CNC machining service is used for precision metal parts such as shafts, bushings, spacers, housings, plates, brackets, flanges, mounting blocks, fittings, fixtures, and small mechanical components. Many OEM projects require CNC machining together with laser cutting, bending, welding, surface finishing, and final inspection.
If your project needs multiple processes, you can review our full manufacturing capabilities to see how CNC machining fits with sheet metal fabrication, robotic welding, and finishing.
Files and Information Needed for Quotation
For a faster CNC machining quotation, please send STEP, IGES, or SolidWorks files for 3D geometry, plus PDF or DWG drawings for critical dimensions and tolerances. It also helps to include material grade, quantity, surface finish, heat treatment or coating requirements, threads, and any inspection points that are important to your assembly.
If you are comparing suppliers or preparing a new project budget, our guides on CNC machining cost and sourcing CNC parts from China explain the main factors that affect price, lead time, and supplier selection.
Tolerances and Quality Control
For suitable materials and part geometry, CNC machining can achieve tight tolerances such as +/-0.01 mm, but the practical tolerance depends on feature size, material, tool access, surface finish, and inspection method. We review drawings before production so critical dimensions, threads, fits, and appearance requirements are clear before machining starts.
Inspection can include dimensional checks, first-article review for new parts, and final quality control before packing. For production orders, we focus on repeatability from batch to batch as well as clean edges, proper deburring, and reliable surface finishing.
CNC Machining FAQ
What materials can you machine?
We commonly machine aluminum, stainless steel, carbon steel, brass, copper, and engineering plastics. If your project uses a special grade, send the drawing and material requirement so we can confirm machinability and sourcing.
What tolerances can CNC machining achieve?
Typical tolerances depend on the drawing, material, feature size, and part structure. Tight tolerances such as +/-0.01 mm may be possible on suitable features, while larger or more complex parts may need practical tolerances confirmed during engineering review.
Can you support prototypes and production runs?
Yes. We support prototype machining, small batches, and production runs for OEM metal parts. For repeat orders, we can keep process notes and inspection requirements to improve consistency over time.
What files should I send for a CNC machining quote?
Please send 3D files such as STEP or IGES together with 2D drawings that show tolerances, thread details, surface finish, material, and quantity. Photos or samples can also help when replacing an existing part.
Get a Quote
Send us your drawings, material requirements, tolerances, surface finish, and quantity. Our team will review your project and provide a quotation within 24 hours.
If you already have finished drawings, tolerances, and CAD files, our CNC machining team can also support build-to-print manufacturing for repeat OEM metal parts.
Not sure whether your CNC project should be quoted as build-to-print or build-to-spec? Read our comparison of build to print vs build to spec before sending RFQ files.
