Can We Mill Your Part?
Start with the part type, feature access, material and production requirements.
Complex Features
Pockets, bores, threads, datum surfaces, thin walls and complex contours.
Materials
Aluminum, stainless steel, steel, brass and engineering plastics.
Production Needs
Prototype, pilot quantities and repeat production.
CNC Milling Capabilities
Choose the axis strategy around feature access, datum transfer, setup risk and the required secondary work. Process visuals are representative.
3-Axis CNC Milling
For plates, housings, accessible features, pockets, holes and profiles reached from a stable setup.
Discuss 3-axis work
4-Axis CNC Milling
For multi-side features, rotary indexing and reduced setup changes around a controlled datum strategy.
Review multi-side access
5-Axis CNC Milling
For complex geometry, angled features, multi-face machining and contoured surfaces with fewer transfers.
Review 5-axis needs
Secondary Operations
Tapping, reaming, deburring and surface-finishing coordination after the primary milling route.

Before Machining Starts
Engineering Support Before CNC Milling
The review turns drawing requirements into a machining and inspection plan before material is committed.
Start a drawing reviewTolerance Review
Review critical dimensions and avoid unnecessary tight tolerances on non-functional features.
Datum & Inspection Planning
Review datum relationships and define measurable critical features for inspection.
Tool Access & Geometry
Review deep pockets, internal corners, wall stability and difficult machining areas.
Material & Finish Coordination
Review material condition and finishing requirements before the process route is released.
From Drawing to Production
A five-step path keeps the approved requirements connected to machining, inspection and delivery.

How We Inspect CNC Milled Parts
Incoming Quality Control (IQC) reviews received material information. Later inspection points follow the approved drawing, critical interfaces and project documentation requirements.
First Article Inspection
FAI checks the first completed part against approved critical requirements.
In-Process Inspection
IPQC checks selected features while the machining route is in progress.
Final Inspection
OQC confirms required checks before approved parts move to shipment.
Critical Dimension Measurement
Measurement methods are selected around the feature and inspection plan.
Inspection equipment: CMM, Height Gauge, Micrometer and Caliper, selected according to the feature and inspection plan.
Review inspection planning
CNC Milling Design Considerations
These four drawing decisions can change tool access, workholding, machining stability and inspection planning.
Deep Pockets
Tool reach and rigidity can affect the machining strategy and stable cutting conditions.
Thin Walls
Machining sequence and workholding can affect wall movement and part deformation.
Internal Corner Radius
Tool diameter limits the minimum achievable internal radius and corner access.
Tight Tolerances
Critical tolerances should be applied where part function and interface control require them.

Project Questions
CNC Milling FAQs
Direct answers for engineering and purchasing teams preparing a CNC milling request.
Ask about your partWhat file formats do you accept for a CNC milling quote?
The quotation form accepts DWG, DXF, STEP, STP, STL, IGES, IGS, PDF and ZIP files up to 20 MB.
What tolerances can CNC milling achieve?
HongKe CNC can support tolerances down to plus or minus 0.005 millimetres for reviewed critical features. The achievable result depends on geometry, material, feature size, workholding and inspection method.
What materials can HongKe CNC mill?
HongKe CNC reviews aluminum, stainless steel, steel, brass and engineering plastics against the part geometry, quantity, finish and inspection requirements.
Do you provide DFM feedback before CNC milling?
Yes. The drawing review can cover datum relationships, tool access, deep pockets, internal corners, wall stability, critical tolerances and measurable inspection features before production.
Do you provide inspection reports for CNC milled parts?
Inspection reports are available by project. The drawing review confirms the critical dimensions, measurement method and documentation required for the order.
What information is needed for a CNC milling quote?
Send the 3D model, dimensioned drawing, material, quantity, surface finish, critical tolerances, inspection requirements and delivery destination.
