Multi-axis process fit
Match 3-, 4-, or 5-axis milling to faces, undercuts, and setup count — confirmed in DFM, not a one-size claim.
Precision CNC Milling Service for Complex Geometries & Multi-Axis Parts
3-, 4-, and 5-axis CNC milling for robotics, automation, and industrial assemblies — deep cavities, thin walls, and multi-face parts with DFM before we cut.
Milling proof points
Tolerances confirmed via DFM
Standard delivery ±0.10 mm unless the drawing specifies otherwise. Selected features can reach ±0.01 mm where material and geometry allow.
Inspection you can request
In-house metrology including ZEISS CMM. Pre-shipment scope follows the drawing and agreed plan; FAI and reports on request.
What we provide
CNC milling for prismatic and multi-face metal and engineering-plastic parts — pockets, contours, thin walls, fixture-critical datums, and mating interfaces. We select 3-axis, indexed 4-axis, or 5-axis based on tool access and setup economy, then lock the plan in DFM before quoting. Secondary finishes and hardware assembly are available under the same project when needed.
Process flow
RFQ / CAD review
Upload STEP/IGES and 2D PDF for critical dimensions, GD&T, and finish notes.

We check radii, pocket ratios, thin walls, tool access, and tolerance economy before locking the quote.
Material & process planning
Stock, fixtures, and axis strategy selected for geometry and grade.
Machining
Programmed toolpaths on multi-axis centers with in-process checks at setup changes.
Inspection
Dimensional verification per drawing — CMM and hand tools as required.
Shipping
Protected packaging and documentation aligned to the purchase order.

Multi-face milling evidence
Milled housings and cover plates show pocketed interiors, sealing faces, and side ports typical of enclosure and interface work. Fixturing and tool access are planned so mating faces stay consistent across setups — the same discipline we apply to thin walls and deep cavities.
Fixture plates and interface blocks
Fixture plate
Slotted locating plate with patterned holes for repeatable workholding and multi-face setups.
Interface block
Counterbored ports and front mounting holes for electromechanical and fluid interfaces.
Tolerance and quality
Project limits are always per drawing and confirmed via DFM before we commit a quote. In-house inspection supports ZEISS CMM measurement and calibrated hand tools. Pre-shipment verification follows the agreed inspection plan — not an unconditional promise on every feature of every part. Optional FAI and material documentation (MTR) are available on request.

Applications
Robotics and automation
Housings, brackets, and interface blocks where multi-face accuracy and repeatable fits matter — industry relevance only, not a certification claim.
Industrial equipment
Fixtures, manifolds, and structural milled parts for production machinery.
Electromechanical assemblies
Precision plates, covers, and thermally relevant metal/plastic components.
CNC milling FAQ
When should I choose 5-axis milling over 3-axis or 4-axis?
Use 3-axis for prismatic parts with primary access from one or two setups. Add 4-axis when indexed faces reduce refixturing. Choose 5-axis when undercuts, compound angles, or single-setup multi-face accuracy justify the process — we confirm fit during DFM.
What tolerances do you typically deliver?
Standard delivery is ±0.10 mm on typical milled features unless the drawing specifies otherwise. High-precision ±0.02–0.05 mm and ±0.01 mm on selected features are available where material and geometry allow — confirmed via DFM before quoting.
What does DFM cover before milling starts?
We review CAD for internal corner radii, pocket depth-to-width ratios, thin-wall stability, hole/thread accessibility, and which tolerances are functionally necessary versus costly to hold.
