How We Inspect Turned Parts
Incoming Quality Control (IQC) reviews received material information. Later checks follow the approved drawing, functional interfaces and documentation requirements.
First Article Inspection
FAI checks the first completed part against approved critical requirements.
In-Process Inspection
IPQC checks selected diameters and interfaces while machining 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, tolerance and inspection plan.
Inspection planningMethods are matched to the feature, datum and drawing requirement.
Reports by projectDocumentation requirements are confirmed during quotation review.
Confirmed equipmentCMM, Height Gauge, Micrometer and Caliper.

CNC Turning FAQs
Direct answers for engineering and purchasing teams preparing a CNC turning request.
Which parts are best suited to CNC turning?
CNC turning is well suited to rotational parts such as shafts, sleeves, bushings, pins, rings, couplings, pulleys and flanges. Drawing review confirms feature access, workholding and any secondary milling needs.
What tolerances can CNC turning 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.
Can threads and grooves be included?
Yes. Internal and external threads, relief grooves and functional grooves can be reviewed with the mating interface, tool access, edge condition and inspection requirements.
What materials can HongKe CNC turn?
HongKe CNC reviews aluminum, stainless steel, steel, brass and engineering plastics against the part geometry, quantity, finish and inspection requirements.
How are turned parts inspected?
Inspection follows the approved drawing and project plan. CMM, Height Gauge, Micrometer and Caliper are selected according to the feature, tolerance and documentation requirements.
What information is needed for a CNC turning quote?
Send the 3D model or dimensioned drawing, material, quantity, surface finish, critical tolerances, inspection requirements and delivery destination. The form accepts DWG, DXF, STEP, STP, STL, IGES, IGS, PDF and ZIP files up to 20 MB.
