What Is Milling, And Why Is It So Important In Industry?

Milling is a surface processing method performed to obtain a result with a particular form in the chosen material. It’s a process that does this by cutting the material with a rotating tool that combines multiple movements to get the required part design.

To machine the part with a milling machine (เครื่อง มิ ล ลิ่ ง which is the term in Thai), depending on the design of the machine, it can have different movements. Movement of the turning tool, movement of the worktable in which the material is arranged, or the two movements. The main feature of the grinding process is the elimination of excess material, turning it into a chip that is thrown away.

The Milling Types

The three basic milling operations are cylindrical milling, face milling, and finish milling. Each of them is a way of working aimed at a specific result.

What is milling, and why is it so important to the industry?

Cylindrical Milling

In this procedure, the drill is covered with teeth on its entire circumference; each tooth serves as a tool for cutting the material. This is arranged on the cutter axis of rotation, placed parallel to the material ready to make this cut. These types of milling cutters can make orthogonal or oblique cuts.

Face Milling

In this type of machining, cutting edges are arranged on the circumference and in front of the knife, and it is in a. arranged perpendicular to the surface. In this case, the milling cutter is placed in a tool holder or the machine’s spindle with the axis of rotation perpendicular to the table.

Finish Milling

Similar to face milling in the arrangement of the milling cutter and the part to be modeled, the difference is that the milling cutter can also be placed at an angle together with the axis of rotation. This type of milling is often used to create conical-shaped surfaces. The cutter’s teeth are located on the front and circumference of the cutter.
