Introduction of milling cutter

Introduction of milling cutter
A milling cutter is a rotating tool with one or more teeth used for milling. It is mainly used in milling machines for machining flat surfaces, steps, grooves, formed surfaces and cutting off workpieces.
The milling cutter is a multi-tooth rotary tool, each tooth of which is equivalent to a turning tool fixed on the rotary surface of the milling cutter. When milling, the cutting edges are longer, and there is no empty stroke, and the Vc is higher, so the productivity is higher. There are many types of milling cutters with different structures and a wide range of applications, which can be divided into three categories according to their uses: milling cutters for processing planes, milling cutters for processing grooves and milling cutters for processing forming surfaces.

Milling cutter is the use of rotary multi-flute tool cutting workpiece, is a highly efficient processing method. When working, the tool rotates (for the main motion), the workpiece moves (for the feed motion), the workpiece can also be fixed, but then the rotating tool must also move (while completing the main motion and feed motion). Milling machine tools are horizontal milling machines or vertical milling machines, but also large gantry milling machines. These machines can be normal machines or CNC machines. The cutting process with a rotating milling cutter as a tool. Milling is generally carried out on the milling machine or boring machine, suitable for processing flat surfaces, grooves, a variety of forming surfaces (such as flower milling keys, gears and threads) and special shaped surfaces of the mold.

Characteristics of milling cutter

1、Each tooth of the milling cutter is periodically involved in intermittent cutting.

2、The cutting thickness of each tooth in the cutting process is changed.

3、The feed per tooth αf (mm/tooth) indicates the relative displacement of the workpiece in the time of each tooth revolution of the milling cutter.
