Milling works

Milling (milling processing) is a process of machining treatment, in which the cutting tool (milling cutter) makes rotary motion (with a speed of V), and the work piece– progressive one (with the inning speed of S). Classification of milling can occur in different ways, depending on what you want to highlight as the most meaningful: Depending on the location of the spindle of the machine and the convenience of securing the work piece - vertical, horizontal.

In production, to a greater extent universal milling machinesare used, which allow horizontal and vertical milling, as well as milling with different tools at different angles.

Depending on the type of tool (milling cutter) - end, face, peripheral, shaped, etc. End milling - grooves, channels, undercuts; wells (through grooves), pockets (grooves, which sides extend more than 1 surface), windows (grooves that extend only on one surface).

Face milling - milling of large surfaces. Shaped milling - profilesmilling.

Examples of profile surfaces are gears, worms, etc. There are also specialized cutters intended for cutting (disk cutters). Depending on the direction of rotation of the mill with respect to the direction of its movement (or the movement of the workpiece) - following "to the tooth", when the mill "kneads" the workpiece, a very clean surface is obtained, but there is also a great risk of workpiece breakage with a large material removal; and counter "on the tooth", when the movement of the cutting edge occurs towards the workpiece. The surface turns out to be worse, but productivity increases. In practice, both types of milling are used, "on the tooth" with the preliminary (rough) and "under the tooth" with finishing (clean) processing.
