Our CNC Machining Capabilities
CNC Milling
CNC milling shapes solid plastic and metal materials into high-precision parts through multi-axis cutting processes. Kingco provides 3, 4, and 5-axis milling services for simple and complex geometries.
CNC Turning
CNC turning process is another machining method to remove material from a rotating workpiece, ideal for producing parts with round, cylindrical shapes, threads, and internal bores.
EDM Machining
EDM (Electrical Discharge Machining) uses controlled electrical sparks to erode electrically conductive materials, allowing design for sharp corners, deep pockets, intricate contours, and machining of extremely hard metals.
Types of CNC Machining
3-Axis CNC Machining
As the most fundamental and widely used machining method, 3-axis CNC operates by controlling the cutting tool's movement along three linear axes: X, Y, and Z. It excels in manufacturing simple parts with features on one main face.
4-Axis CNC Machining
4-axis CNC machining unlocks the ability to machine complex sides and cylindrical surfaces in one continuous operation, by adding a rotary A-axis that spins the workpiece. This eliminates multiple setups, streamlining production for parts with rotational symmetry.
5-Axis CNC Machining
5-axis CNC integrates X, Y, and Z axes with two rotary axes (A-axis & B-axis) for simultaneous movement, enabling highly intricate shapes in one setup, ideal for aerospace, medical parts, and impellers, requiring advanced programming but offering maximum flexibility and precision.
CNC Machining Tolerances
Our standard CNC machining tolerances adhere to ISO 2768 (medium) for machined plastics and ISO 2768 (fine) for machined metals.
If your design has critical dimensions or requires higher precision than these standards, please clearly indicate them on your drawings or reach out to our sales.
Actual achievable tolerances may vary based on part size, geometry, material, and complexity. Our engineering team then will give you feedback after evaluating.

CNC Machining FAQs
What is CNC Machining?
CNC (Computer Numerical Control) machining is a precision manufacturing process that uses automated cutting tools to shape metal or plastic components. Based on part complexity, we employ 3-axis, 4-axis, or 5-axis milling machines, or lathes. After receiving your 3D CAD model, our experienced machinists program optimized tool paths to minimize costs and maintain tight tolerances.
What are the advantages of CNC Machining?
CNC machining consistently produce parts with extremely tight tolerances (often within ±0.025 mm or better) and smooth surface finishes down to Ra 0.8. It also handle a wide range of engineering materials, part size, and complex geometries. Ensuring the consistent quality for your prototype parts and production end-use parts.
Do you have a MOQ (minimum order quantity)?
No, we can handle your orders in on-demand quantity. Kingco provides machining services from rapid prototyping to medium-run production.
What type of design files does Kingco accept for quoting and production?
For optimal processing, we prefer 3D drawings in STEP, IGES, or X_T format, and 2D drawings in PDF, or DWG format with dimensional tolerances where applicable.
What general tolerances can Kingco machining achieve?
We typically adhere to ISO 2768 (medium) for plastics machined parts and ISO 2768 (fine) for metals machined parts, unless otherwise specified.
What precision tolerances can Kingco machining achieve?
CNC Precision Machining Tolerances down to ±0.003mm. Kingco can machine and inspect to tight tolerances per your drawing specifications.
What’s your standard lead time for CNC machined parts?
Typically, simple CNC machined parts can be done within 2 days, while it might take 15+ days to make complex or big CNC machined parts. Quantity is another matter to be considered.
