How to Determine Which Parts Are Best Made by CNC Turning?

Symmetry and Geometry - CNC turning is particularly advantageous for parts with symmetrical geometries due to its rotational nature. Parts with rotational symmetry, such as shafts, cylinders, and discs, are ideally suited for CNC turning to ensure uniformity and precision.

Cylindrical & Round Shapes - Turned parts are inherently cylindrical or round, and either solid or hollow, primarily due to the nature of the turning process. This cylindrical form is well-suited for a wide range of applications across various industries, including automotive, aerospace, and manufacturing. Solid cylindrical parts, such as shafts and pins, provide structural support and transmit motion or power efficiently. Hollow cylindrical parts, like tubes and sleeves, offer lightweight construction and fluid passage capabilities

For less complex parts, CNC turning can efficiently produce features such as outer diameters, inner bores, and facing operations using standard turning tooling and techniques. For more complex parts requiring additional features or secondary operations, CNC turning machines equipped with live tooling, sub-spindles, and multi-axis capabilities can perform drilling, milling, tapping, and thread-cutting operations directly on the turning center.

CNC turning can accommodate a wide range of materials, including metals, plastics, and composites. Common materials used in CNC turning include aluminum, brass, stainless steel, carbon steel, titanium, copper, and various engineering plastics such as nylon, acetal, and polycarbonate. CNC turning can also machine specialty materials like ceramics, fiberglass, and certain types of wood, depending on their machinability characteristics and application requirements.
