Differences between machining and turning

In the metal parts manufacturing industry, it is common to come across the terms turning and machining, but how are these two techniques different? Although both processes are used to manufacture components from raw materials, they have different approaches and applications

Turning is a manufacturing process that focuses mainly on the production of cylindrical parts by removing chips. It is characterized by the use of automatic lathes, whether conventional or numerically controlled (CNC). Using long metal bars, such as steel, aluminium or brass, bar turning allows you to machine components such as screws, bolts, axles, bushings and other small elements.

One of the main advantages of bar turning is its high efficiency in the production of pieces in large volumes. Furthermore, its ability to work with small diameters makes it an ideal option for sectors such as electronics and plumbing, where very precise components with guaranteed repeatability are needed

Machining is a broader term that encompasses various techniques for cutting, moulding and shaping a material, including milling, turning and drilling. Unlike bar turning, machining is not limited to cylindrical parts or bars of material. It can be made in a wide variety of shapes and materials, making it more versatile for manufacturing larger, complex parts.

Machining also uses computer-controlled (CNC) tooling to ensure precision, but is especially useful for producing custom parts or shorter runs in a variety of industries, from aeronautics to heavy machinery.

In summary, both processes are fundamental in the modern manufacturing of components and parts, but while turning stands out in the mass production of cylindrical parts, machining offers more flexibility in terms of part shapes and sizes.
