Custom CNC machining services
Custom CNC machining services for precision CNC parts.
Bring CNC milling, turning, multi-axis machining, inspection and surface finishing into one drawing-led workflow for prototypes, bridge production and repeat orders. Our precision CNC machining services begin with the controlled model and drawing—not a generic part description.

CNC machining capabilities
Choose the process route around the custom CNC part.
Choose the closest route or upload the drawing and let geometry, datum relationships, quantity and inspection needs guide the process.
CNC Turning
For shafts, sleeves, bushings, threaded fittings and other rotational components.
Explore CNC Turning5-Axis Machining
For complex surfaces and features that benefit from fewer setups and multi-directional access.
Explore 5-Axis MachiningCNC Routing
For panels, sheet parts, large profiles, cutouts and suitable plastic or aluminum plate.

Prototype to repeat production
Plan the production route before volume increases.
Prototype feedback is more useful when the intended material, finish, inspection scope and repeat quantity are already visible. That lets the team review workholding, setup reduction and revision control earlier.
Drawing and requirement review
Upload the 3D model and controlled drawing with material, quantity, finish and critical inspection requirements.
DFM and process planning
We review feature access, setups, datum strategy, tool reach, tolerance relationships and secondary operations.
Machining and in-process control
The approved route combines appropriate milling, turning or multi-axis operations with process checks.
Inspection, finishing and delivery
Specified dimensions, finish requirements, documentation and packaging are confirmed against the order.
CNC machining materials
Specify the exact grade—not only the material family.
Strength, corrosion behavior, thermal performance, stability, chip formation and finishing compatibility can change by grade. Final availability and process suitability are confirmed against the drawing.

CNC machined part examples
Complex aluminum housings shown in one clean visual system.
Each example highlights a different combination of cavities, bores, threads, ribs, sealing faces and mounting features—useful references when preparing a comparable RFQ.
Multi-face bearing housing
Bearing seats, intersecting bores and mounting faces are planned around a consistent datum structure so fit and assembly relationships can be inspected clearly.

Multi-port machined housing
Threaded ports, internal cavities and sealing faces require coordinated tool access, deburring and post-machining inspection.

Structural equipment housing
Ribs, mounting ears and a large precision opening combine structural geometry with functional interfaces that must be controlled in the same setup plan.

Precision engine housing
Large bores, bolt patterns and smaller fluid or fastening features are reviewed together for concentricity, positional control and practical inspection access.

Connect every critical feature to a datum and inspection method.
A useful inspection plan begins with the controlled drawing. Mark functional dimensions, fits, cosmetic zones and documentation needs so machining and inspection teams evaluate the same requirements.

Explore quality control CNC machining design guide
Design decisions that make machining clearer and more controllable.
These are review topics, not universal limits. Your drawing, material and functional requirements determine the final recommendation.
Internal radii
Allow realistic cutter radii in pockets and internal corners instead of specifying perfectly sharp internal geometry.
Wall and floor stability
Very thin sections can move during cutting or finishing; identify which surfaces control fit and appearance.
Deep features
Deep cavities and small-diameter holes need tool-reach, chip-removal and inspection review.
Threads and inserts
State thread standard, engagement requirement, insert type and any post-finish gauging needs.
Tolerance priorities
Apply tight tolerances to functional relationships and use practical general tolerances elsewhere.
Datums and inspection
Define a datum structure that reflects assembly function and provides a repeatable inspection setup.
Surface finishing after machining
Define color, texture, masking and dimensions after finish.
Anodizing, plating, passivation, powder coating, painting, polishing and other treatments interact differently with each substrate. Put cosmetic zones and post-finish dimensional requirements on the drawing.

Answers for engineering and procurement teams.
When tolerance, material or process suitability depends on geometry, upload the controlled drawing for review.
What files should I send for a CNC machining quote?+
Send a STEP or STP model whenever possible together with a controlled PDF drawing. Include material grade, quantity, surface finish, critical tolerances, inspection needs and the required delivery location.
How do you choose between CNC milling, turning and 5-axis machining?+
The decision depends on part geometry, feature access, datum relationships, quantity and inspection requirements. Rotational parts often suit turning, prismatic parts suit milling, and complex multi-face geometry may benefit from 5-axis machining.
Can one project combine turning and milling?+
Yes. Parts with both rotational and off-axis features may require a combined route. The model and drawing are reviewed before the process is confirmed.
Which metals and plastics can be CNC machined?+
Common projects use aluminum, stainless steel, steel, brass, copper and engineering plastics. Titanium and other specified materials can be reviewed by project. Always state the exact grade rather than only the material family.
Can you provide surface finishing after machining?+
Surface finishing can be included in the project review. Options depend on the substrate and requirements, including anodizing, plating, powder coating, painting, passivation, polishing and other specified treatments.
What information affects CNC machining cost?+
Material, stock size, machining time, setup count, tool access, tolerance, surface finish, inspection scope, quantity and secondary processes all influence quotation.
How should critical tolerances be shown?+
Identify functional dimensions and datum relationships on the drawing. Avoid applying the tightest tolerance to every feature; use fit, function and inspection needs to define what is truly critical.
Can you support prototypes and repeat orders?+
Projects can be reviewed from prototype through repeat production. Revision control, inspection planning, finishing and packaging should be defined early when repeatability is important.
