What is milling?

Milling is one of the common machining processes in which, unlike the turning process, the part is fixed (or moves linearly) and the multi-edged cutting tool or the milling blade rotates (with the help of the spindle of the milling machine) and He scrapes on it. One of the defining characteristics of the milling process is the multi-edge of the tool. A diverse set of machining devices based on the milling process (fixed part, moving tool) has been designed and manufactured, each of which is called a milling machine. These machines can be used for various operations such as face milling, grooving, drilling, cutting parts, creating gears, creating inclined surfaces, etc.

In all milling machines, there is a spindle axis to rotate the tool, based on its alignment, milling machines are classified into three general groups. Devices with a horizontal rotation axis are called horizontal milling machines, and devices with a vertical rotation axis are called vertical milling machines. Devices that have the ability to rotate and be placed in both vertical and horizontal positions are called universal milling machines. The general structure of all milling machines is similar to each other to a large extent, and we will refer to them in the following headings. Column and Base or Column and Base Car knee or Knee sack table main table Spindle Milling rod or drain or arbor Upper arm or Overhanging Arm in horizontal mills Circulating arm or RAM in vertical mills

General milling machines are divided into three types: horizontal, vertical and universal. In addition to general milling machines, different types of milling machines have been made for special applications, which are called special milling machines. Many examples of these devices are released every year, and we will discuss the most common ones below. Gate milling machines: these types of machines are mostly used in industrial production and series turning. The special application of these devices is milling of large parts, and it is possible to perform the machining process simultaneously on different surfaces (top and side). Copy lathe milling machine: In this type of machine, a part is considered as a template and with the help of different mechanisms, the movement of the furnace blade is adjusted and the workpiece is machined according to the template. Copiers can be designed for two-dimensional or three-dimensional modeling or both.

In milling machines, the machining tool is called a milling blade. These blades have different types in terms of shape, geometry, and material, which we will refer to below in a title-wise manner. Milling machines are one of the most widely used machine tools used in the industry. The reason for the popularity of this device is its ability to perform a wide range of machining processes. Obviously, performing processes such as grooving or gear cutting requires a different tool than face turning or threading, and the strength of milling machines is the presence of many types of tools for different functions. The types of burr blades are: The blade of roller mills The blade of the front roller milling cutters The blade of finger mills Flake or disk milling blade Forming milling cutters Headboring or crank drill The blade of angle cutters
