Machining techniques, milling and turning
Milling and turning are commonly used for machining mechanical parts, mechanical assemblies and sub-assemblies as well as wear and safety parts. These complementary processes participate in the production of high precision mechanical parts in a wide variety of industries: energy, food processing, aeronautics, etc.
The difference between milling and turning
Milling and turning are two similar and complementary machining techniques. They allow you to trim material on a part in order to give it the desired shape. These techniques are used to shape all types of hollow shapes such as a cylindrical hole or a groove in a mechanical part for example, but also to obtain solid cylinders. The difference between milling and turning is in the movements made by the machine tool.
Milling is carried out using a milling cutter mounted on the milling machine. This machine makes it possible both to remove material and to advance the part as the trimming progresses. To increase productivity and precision, most machining centers now use CNC milling machines.
Milling combines two movements: the cutting rotation of a tool with several edges and the rectilinear feed of a part known as the feed movement. However, it is customary to move the tool relative to the workpiece, which can be done in virtually any direction.
Generally, milling is used to obtain flat surfaces, shoulders and grooves. It can be performed on a wide range of machine tools, from classic milling machines to the new generation CNC (Computerized Numerical Control) machines developed with multiple axes.
The choice of milling tool and the type of operation will depend on the part drawing and production requirements. The advantages of milling are multiple: in addition to its high performance, it allows an excellent surface finish, great precision and increased flexibility in its shapes.
Turning is carried out with a single rotary movement. Unlike milling, it does not advance the part. The latter is immobilized in a mandrel or by a clamp. The cutting tool can trim the inside and outside of the workpiece with a precise feed motion. Besides shaping cylindrical shapes, this technique is mainly used for turning screws, bolts and other fasteners.
