What is CNC Milling ?CNC milling involves cutting solid plastic or metal materials to precision using various axis milling techniques. Unlike CNC lathes, mills shape workpieces by rotating and maneuvering a cutting tool like a milling cutter, positioning the workpiece accurately to achieve a final or semi-finished shape. Multi-axis milling machines enable versatile, precise, and consistent CNC milling for producing diverse features and intricate geometries such as channels, holes, curves, and corners. Additionally, milling serves as an ideal method for crafting tooling essential for die casting and injection molding processes.

CNC Milling Tolerances
Hongsinn offers a range of CNC machining tolerances to meet your unique design requirements, including GD&T callouts. Depending on your part geometry and selected material, we can provide standard thread sizes, machine custom threads, and achieve tolerances up to ±0.001”. Our standard tolerances for CNC milled metals are ISO 2768-m and our standard tolerances for plastics are ISO 2768-c.

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.
