What is CNC Milling

CNC milling is the process of shaping solid plastic or metal materials with precision through different axis milling methods. Unlike CNC lathes, milling machines cut by rotating and moving a cutting tool like a milling cutter, accurately positioning the workpiece to achieve a final or semi-finished shape. Multi-axis milling machines offer versatility, precision, and consistency in creating a variety of features and complex geometries like channels, holes, curves, and corners. Moreover, milling is crucial for producing tooling needed in die casting and injection molding processes.

CNC Milling Tolerances
At Hongsinn, we provide a variety of CNC machining tolerances tailored to your specific design needs, incorporating GD&T callouts. Depending on your part's geometry and material, we offer standard thread sizes, can machine custom threads, and achieve tolerances as tight as ±0.001 inches. Our standard tolerance levels for CNC milled metals adhere to ISO 2768-m, while for plastics, we follow ISO 2768-c standards.

Feature
Description
Maximum Part Size
Milled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm). Lathe parts up to 62” (1,575 mm) length and 32” (813 mm) diameter.
Standard Lead Time
3 business days
General Tolerances
Tolerances on metals will be held to +/- 0.005"(+/- 0.127 mm) in accordance with ISO 2768 unless otherwise specified. Plastics
and composites will be +/- 0.010”.
Precision Tolerances
We can manufacture and inspect to tight tolerances per your drawing specifications including GD&T callouts.
Minimum Feature Size
0.020” (0.50 mm). This may vary depending on part geometry and chosen material.
Threads and Tapped Holes
We can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review.
Edge Condition
Sharp edges are broken and deburred by default
Surface Finish
The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote.
 
Features
Description
Internal corner fillets
Design internal corner fillets to be 0.020” - 0.050” greater than a standard drill size for the radii. Follow a drill diameter to
depth ratio of 1:6 (1:4 recommended) as a guideline for internal corner radii.
Floor fillets
Design floor fillets smaller than corner fillets to allow the same tool to clear material from the interior.
Undercuts
Always design undercuts to standard sizes and away from corners so they are accessible by the cutting tool.
Tapped/threaded hole depth
Provide tool clearance slightly beyond the tapped hole depth to ensure complete threads.
Complexity
Keep the number of small cuts to a minimum to reduce CNC machining costs; only design in the necessary features to balance
function with aesthetic.
