Choose the machining route around part geometry—not only the machine name

Hongming Sheng supports custom CNC components from one-piece prototypes to repeat production. Our capabilities include 3-axis, 4-axis and 5-axis milling, CNC turning and Swiss-type machining.

The process is selected according to geometry, material, tolerance location, surface requirements and quantity.

Processes How to Choose Materials Quality Quote

Core CNC Machining Processes

3-Axis CNC MillingSuitable for plates, housings, pockets, hole patterns and parts machined mainly from one or several accessible directions.

4-Axis CNC MillingAdds controlled rotation for features around a part, reducing some repositioning and supporting more complex geometry.

5-Axis CNC MillingUsed when multiple faces, compound angles or complex contours require coordinated tool access.

CNC TurningSuitable for shafts, sleeves, bushings, rings, threads and other mainly rotational components.

Swiss-Type MachiningUseful for long, slender or small-diameter precision parts with repeated turned and milled features.

Secondary MachiningDrilling, tapping, reaming, countersinking, deburring and finishing may be added as the drawing requires.

How We Select the Manufacturing Route

Read the Drawing

Identify critical dimensions, datum relationships, threads, surface finish and cosmetic areas.

Review the Geometry

Determine tool access, workholding, required axes and whether milling, turning or a combined route is suitable.

Plan Operations

Select stock size, setup sequence, cutting tools and in-process inspection points.

Validate & Produce

Confirm the sample against agreed requirements before repeat production.

Common CNC Materials

Aluminum6061, 7075 and specified grades

Stainless Steel304, 316 and drawing-specified grades

SteelCarbon and alloy steels

Copper / BrassConductive and mechanical parts

TitaniumEvaluated by grade and geometry

Engineering PlasticsPOM, nylon and other specified materials

Material condition can affect machining, dimensional stability and finishing. Please include the full grade and temper where applicable.

Tolerance & Quality Planning

A blanket tolerance is rarely appropriate for every feature. Critical requirements should be identified on the drawing so machining and inspection can be planned accordingly.

Drawing and revision confirmation

Material specification review

First-piece and in-process dimensional checks

Final inspection of agreed critical features

Inspection records or material documents when agreed for the order

For many CNC projects, critical tolerances around ±0.01 mm can be evaluated, but feasibility depends on feature size, material, geometry and measurement method.
