Custom CNC Milling
Services
Plan pockets, holes, flat faces and multi-face access from the drawing outward.
Our CNC milling service is suited to prismatic parts such as housings, brackets, plates, fixtures and heat sinks. We review the relationship between pockets, holes, flat surfaces, thin walls and datums before choosing the machining sequence. The stated maximum milling envelope is 1200 × 850 × 600 mm; final feasibility remains dependent on material, fixturing, wall stiffness and feature access.

MANUFACTURING CAPABILITIES
CNC Milling
for Drawn Geometry
A good milling plan begins with the locating faces and functional datums. It then selects the axis configuration and setup sequence that give the cutter access to pockets, holes and side features while protecting thin walls and critical relationships.
Our Full Capabilities →
4-Axis CNC Milling Service
Rotary-axis positioning can expose features around a part with fewer re-clamps. It is considered when indexed side access improves alignment between holes, flats and other multi-face details.

5-Axis CNC Milling Service
Used when compound angles, difficult access or multiple critical faces make an indexed or simultaneous multi-axis strategy more suitable. The process is selected from the drawing, not assumed for every complex part.

Choose the Right
Material for Your Part.
For milled parts, material rigidity, thin-wall behavior, pocket depth, thermal behavior, fixture strategy and finish requirements all affect the machining sequence and the features that need protection.

SURFACE FINISHES
The Finish That
Fits Your Application.
Identify flat mounting faces, critical holes, threads and surfaces that must remain as machined before selecting a cosmetic or protective finish. Specify any masking or downstream assembly requirement in the drawing.
As Machined
A precise, cost-effective finish straight from the CNC process for functional features and tight tolerances.
View MoreAnodizing
Improves corrosion and wear resistance on aluminum, with clear, black and custom color options.
View MorePolishing
Reduces surface roughness to create a smooth, refined appearance for visible precision components.
View MoreSandblasting
Creates a uniform matte texture and can reduce visible machining marks on suitable parts.
View MorePowder Coating
A durable, protective coating with a broad range of colors and textures.
View MoreElectroplating
Adds a protective or decorative metal layer for performance and appearance.
View MoreBlack Oxide
A dark conversion finish for steel parts requiring a low-reflective, corrosion-resistant surface.

CNC Milling
for Real-World Applications
Suitable for housings, brackets, plates, fixtures, heat sinks and other prismatic parts that need controlled pockets, holes, flat faces or multi-face relationships. The relevant question is feature access and datum strategy, not industry label.

BUILT FOR DEMANDING PROJECTS
Milling Inputs That
Shape the Plan
The drawing review focuses on the locating faces, accessible features and fixture approach that determine whether 3-, 4- or 5-axis access is appropriate.
Datum Review
Identify the locating faces and functional datums that control the part’s critical relationships.
Feature Access
Review pockets, holes, side features and multi-face details before selecting the axis configuration.
Wall & Fixture Strategy
Thin walls, open pockets and material stiffness affect clamping and machining sequence.
Surface Requirements
Separate functional faces from cosmetic surfaces and identify areas that must remain as machined.
Inspection Inputs
Call out critical holes, flatness-related relationships and documentation requirements in the drawing.
A CLEARER PATH TO YOUR PARTS
From Drawing to Delivery
The milling plan is built around datums, feature access, wall condition and finish keep-out areas before any axis configuration is selected.
01
Send Drawings
Provide 2D/3D drawings with material, quantity, datums, critical holes, wall conditions, tolerance and finish requirements.
02
DFM Review
Review datum strategy, tool access, pockets, thin walls, fixture approach and finish keep-out areas.
03
CNC Milling
3-, 4- or 5-axis milling is selected for the required pockets, holes, faces, feature access and datum relationships—not simply by part size.
04
Quality Inspection
Drawing-defined checks for datum-related features, pockets, holes, flat faces and agreed documentation.
05
Delivery Planning
Production and shipment planning based on the agreed schedule, approved drawing, finish and shipping terms.
QUALITY ASSURANCE
Quality Built In.
Confidence Delivered.
Inspection is planned from the locating faces, functional datums and features that affect assembly. T-One applies 100% inspection against the drawing and agreed inspection requirements; dimensional, CMM, FAI and material documentation can be provided when specified.

ItemSpecification
Datum-related featuresPockets, holes, flat faces and multi-face relationships are checked against the drawing. Standard CNC tolerance is ±0.01 mm; critical features may be reviewed to ±0.005 mm subject to material, structure and drawing requirements.
Inspection ApproachProcess-appropriate visual, dimensional and functional checks.
Inspection StandardsBased on customer drawings and agreed specifications.
DocumentationInspection information and material documentation available when specified.
Quality PlanningRequirements reviewed before production and monitored through delivery.
FROM PROTOTYPE TO PRODUCTION
Flexible Volumes.
Consistent Quality.
Timing is planned after the drawing is frozen and the fixture, material, quantity, finish and inspection requirements are understood.
Prototypes
Typically 3–7 days after requirements are confirmed · Validate datum strategy, wall condition and critical features
Low-Volume Production
Plan fixture approach, material and finish before scheduling · Confirm inspection requirements
High-Volume Production
Typically 25 days after drawing freeze · Timing depends on part geometry, quantity, secondary operations and inspection scope
