What don't you know about milling cutter

The characteristics of milling cutter, milling cutter used in milling, with one or more cutter teeth of the rotating tool. Each cutter tooth is equivalent to a turning tool fixed on the rotary surface of the milling cutter. In milling, the cutting edge of cutting at the same time is longer, and the empty stroke is higher, so the productivity is higher.

There are many kinds of milling cutters with different structures and a wide range of applications, which can be divided into three categories: milling cutters for machining plane, milling cutters for machining groove and milling cutters for machining forming surface.

Most of the cylindrical milling cutters are made of high-speed steel as a whole. The spiral cutting edge is distributed on the surface of the cylinder, and there is no auxiliary cutting edge. The spiral cutter teeth are gradually cut and separated from the workpiece when cutting, so the cutting process is relatively stable. Most of them are used in horizontal milling machine to process long and narrow plane whose width is less than the length of milling cutter.

Most of the face milling cutters are used in vertical milling machine or horizontal milling machine for machining step surface and plane, especially for machining larger plane. The Face Milling Cutter with main deflection angle of 90 ° can mill wide step surface at the bottom. When a face milling cutter is used to process a plane, more cutter teeth are involved in the cutting, and the polishing effect of the auxiliary cutting edge is also provided, so that the surface roughness value is small. Therefore, a larger cutting amount can be used, the productivity is higher, and the application is wide.

End milling cutter is a kind of conventional milling cutter in numerical control milling. Its shape, the cutting edge on the cylindrical surface is the main cutting edge, and the end surface is scattered with auxiliary cutting edges. The main cutting edge is generally spiral teeth, which can improve the cutting stability and increase the machining accuracy. Because there is no cutting edge in the center of the end face of the ordinary end milling cutter, the end face edge is mainly used to process the bottom plane perpendicular to the side.

It is used for machining all kinds of groove and step surface. There are cutter teeth on both sides and circumference.

Angle milling cutter, used for milling groove into a certain angle, there are two kinds of single angle milling cutter and double angle milling cutter.

Saw blade milling cutter is used to process deep groove and cut workpiece, and there are many cutter teeth on its circumference. In order to reduce the friction during milling, there are 15 ′ ~ 1 ° offset angles on both sides of the cutter teeth. In addition, there are keyway milling cutter, dovetail groove milling cutter, T-shaped groove milling cutter and various forming milling cutters.

Features of milling cutter
1. Each tooth of milling cutter participates in intermittent cutting periodically.
2. The cutting thickness of each cutter tooth changes during the cutting process.
3. The feed rate of each tooth α f (mm / tooth) represents the relative displacement of the workpiece during each tooth rotation of the milling cutter.

The above is the brief introduction, features, types and types of milling cutters introduced by shenganbei. In the actual production and application, when the milling cutter is passivated, we should stop in time to check the wear of the milling cutter. If the wear is slight, the cutting edge can be polished with oilstone, and then it can be used again. If the wear is heavy, the milling cutter must be grinded to prevent excessive wear,
