ISO 9001:2015 Certified CNC Manufacturer
Custom CNC Milling Services
Get precision parts in metals, engineering plastics, composites and ceramics with 3-, 4- and 5-axis CNC milling. Weldo supports prototypes, small batches and bulk production with engineering review and controlled inspection.
Select the Right Machining Route
3-, 4- and 5-Axis CNC Milling
The suitable axis configuration depends on feature access, part geometry, datum relationships, surface requirements and production volume.
3-Axis CNC Milling
A practical choice for plates, brackets, housings, pockets, holes and features accessible from one primary direction.

4-Axis CNC Milling
Rotary positioning supports circumferential features and machining on multiple sides with fewer manual reorientations.
Explore 4-Axis CNC Milling →
5-Axis CNC Milling
3+2 positioning and simultaneous 5-axis machining support compound angles, complex surfaces and multi-face parts with fewer setups.

CNC Milling From Prototype to Production
Use one controlled manufacturing route from design validation through stable production.
Functional Prototypes
Representative parts for fit, assembly, material and functional testing.
Low-Volume Production
Controlled tooling, programs, inspection points and finishing for small batches.
Bulk Production
Controlled programs and inspection plans support consistent volume production.
Engineering Reference
CNC Milling Capabilities
Final capacity and tolerance depend on material, geometry, setup, feature location and inspection requirements. Critical dimensions are confirmed after drawing review.
Metals and Engineering Plastics
Materials for CNC Milling
Material selection considers strength, weight, corrosion, temperature, dimensional stability, machinability and cost. Exact grades and conditions are confirmed for each project.
Aluminum
Lightweight, corrosion-resistant and easy to machine. Used for housings, brackets, heat sinks and structural parts.
Materials are sourced and evaluated according to the project specification. Availability and certification requirements are confirmed during quotation.
Appearance and Performance
Surface Finishes for CNC-Milled Parts
Select a finish according to material, corrosion exposure, wear, appearance and dimensional requirements.
Machined Finish
Retains controlled tool marks after machining and requires no additional coating.
Anodizing
Improves corrosion and wear resistance and supports colored protective finishes on aluminum.
Sandblasting
Creates a uniform matte texture and can prepare the surface for subsequent finishing.
Electroplating
Adds a metallic coating for corrosion protection, wear performance, conductivity or appearance.
Design for Machinability
CNC Milling Design Guidelines
Practical radii, wall thicknesses, hole depths and thread details help reduce tool deflection, vibration and unnecessary machining cost.
Internal Radii
Use practical corner radii that allow a suitable end mill and reduce tool load.
Threads
Specify thread size, depth and critical engagement; avoid unnecessary full-depth threading.
Wall Thickness
Balance stiffness, material behavior and tool access to reduce vibration or distortion.
Engraved Text
Use open, readable geometry and confirm the required depth and visual priority.
Holes
Define diameter, depth, tolerance and whether the hole is blind, through, reamed or threaded.
Final recommendations follow drawing review.
From CAD to Shipment
Controlled CNC Milling Workflow
Inspection is planned around drawing requirements and critical features.
File and Requirement Review
Check CAD, drawings, material, quantity, finish and inspection requirements.
DFM and CAM Programming
Confirm setup strategy, tool access and the required milling route.
Setup and Program Verification
Verify fixtures, datums, tools and critical program movements.
CNC Milling and In-Process Checks
Monitor key features during machining to control variation.
Final Inspection, Finishing and Delivery
Inspect drawing requirements, complete finishing and prepare protected shipment.

Manufacturing Evidence
Why Work With Weldo Machining
Engineering review, controlled machining and inspection support reliable project delivery.
What files should I provide for a CNC milling quote?
Send 3D CAD files and a 2D drawing when available. Include material, quantity, tolerances, finish and inspection requirements.
How do you choose between 3-, 4- and 5-axis milling?
The route depends on feature access, geometry, datum relationships, setup count and tolerance requirements.
What tolerances can CNC milling achieve?
Weldo uses ±0.001 in as the standard dimensional tolerance. Selected precision features can reach ±0.0002 in after drawing, material and inspection review.
Which metals and plastics can you mill?
Common choices include aluminum, stainless steel, steel, copper alloys, titanium and a broad range of engineering plastics.
Can you provide finishing and inspection reports?
Finishing and inspection are planned to the drawing. Report and certification requirements should be stated during quotation.
Do you support prototypes and bulk production?
Yes. Weldo supports functional prototypes, low-volume batches and bulk production with controlled programs and inspection plans.
