Rotating tools for machining of materials, consisting of a series of teeth and cutting edges, usually arranged symmetrically around an axis. The teeth and cutting edges remove material from the workpiece intermittently, turning it into a finished piece with the shape and dimensions desired.
The classification of milling may be performed according several criteria, as follows:
The method of milling
Peripheral milling cutters, also called tangential
Milling Cutters Front
Regarding the type of construction of the mills
Body type or block only - solid
Body with teeth welded
Body with replaceable teeth fixed with clamps and / or screws
As the geometric shape of the cutters
Cylindrical body with large width or length (mill cylindrical)
Cylindrical body with a small width (disc cutter)
Cylindrical body with a small width (saw)
Body cylindrical rod suitable for mounting (mill rod)
Conical body, with or without stem itself to setting (Angle)
Body with special or particular manner (with Profile constant)
Regarding the type of edge or surface of incidence of cutters
Milled surface with incidence
Relief grinding surface with incidence
As the shape of the teeth of the cutters and the channels between teeth
With teeth and straight channels
With helical teeth and channels (right or helical left)
With teeth and channels bi-helical
The direction of cutting cutters
Cutter with the cutting direction to the left
Cutter with the cutting direction at right
As for mounting or fixing the milling machine (Milling machine)
Mounting on an auxiliary shaft (about chuck)
Assembly through its own stem
With mounting bolts and cotter pin (cutters front)
Regarding the implementation of the cutters
For machining of various channels and tears
For machining recesses for braces
Guides for drilling machines
For machining of gears
For thread cutting
To accomplish recesses in surfaces
