The difference between turning insert and milling insert

Turning insert and milling insert are two different cutting tools, which are used for cutting operations in metal processing and machining. They have obvious differences in structure, application scenarios and working methods.

Working mode:

Turning insert: Turning is a rotary cutting process, which removes the outer surface of the workpiece by rotating the workpiece and moving the tool along the axial direction of the workpiece. The turning insert is installed on the tool rest of the lathe, which can remove metal along the axial direction of the workpiece, thus obtaining the required shape and size.

Milling insert: Milling is a rotary cutting process, which cuts the surface of the workpiece by moving the tool in the horizontal or vertical direction. The milling insert is installed on the milling machine, which can cut the workpiece in horizontal, vertical or multi-axis directions to form planes, concave-convex surfaces, grooves and other complex shapes.

Cutting principle:

Turning insert: the turning insert rotates along the axial direction of the workpiece on the lathe, and uses the cutting edge of the cutting blade to cut off the metal material. The cutting mode of turning insert is similar to milling, but it mainly cuts in the radial direction.

Milling insert: the milling insert cuts off the material on the workpiece by rotating the cutting tool. The cutting mode of milling insert is mainly in radial and circumferential direction, so it can realize cutting of various shapes.

Application scenario:

Turning insert: turning is mainly used to process cylindrical workpieces, such as shafts, holes and discs. It can realize high-precision machining and is suitable for rough machining and finish machining.

Milling insert: Milling is mainly used for machining planar and complex workpieces, such as planes, grooves, gears, etc. It is suitable for mass production and processing of workpieces requiring various shapes.

Tool structure:

Turning insert: Turning insert generally has single edge or multiple edges, and the cutting edge is usually straight.

Milling inserts: Milling inserts usually have a multi-blade structure, and the cutting edges are straight, spiral, spherical and so on, which are used to achieve different cutting effects.

Generally speaking, turning insert and milling insert are important cutting tools, and they have their own advantages and application scenarios in the field of metal processing. Choosing the right tool depends on the specific machining requirements and the shape of the workpiece.
