How much do you know about corn milling inserts?

Latest company news about How much do you know about corn milling inserts?

To understand the milling cutter, you must first understand the knowledge of milling. When optimizing the milling effect, the insert of the milling cutter is another important factor. In any milling, it is an advantage if there are more than one inserts participating in the cutting at the same time, but the inserts participating in the cutting at the same time are advantageous. Too many numbers are a disadvantage. It is impossible for each cutting edge to cut at the same time during cutting. The required power is related to the number of cutting edges participating in the cutting. In terms of the chip formation process, cutting edge load and processing results, the milling cutter is relative to the workpiece. location plays an important role. In face milling, with a cutter that is about 30% larger than the cutting width and positioned close to the center of the workpiece, the chip thickness does not change much. The chip thickness in the plunge and exit is slightly thinner than that in the center cut.

The radial cutting force and the axial direction of the milling cutter with a leading angle of 45 degrees are roughly equal, so the pressure generated is relatively balanced, and the requirements for the power of the machine tool are also relatively low, especially suitable for milling short-chip materials that produce chipping chips artifact. A milling cutter with round inserts means that the entering angle varies continuously from 0 to 90 degrees, depending on the depth of cut. The strength of the cutting edge of this kind of insert is very high. Since the chips generated along the long cutting edge are relatively thin, it is suitable for large feeds. The direction of the cutting force along the radial direction of the insert is constantly changing, and the pressure generated during the machining process. Will depend on the depth of cut. The development of modern insert geometry makes the circular insert have the advantages of smooth cutting effect, low power requirement of the machine tool, and good stability. Today, it is no longer an effective roughing cutter and is used in a wide range of face and end milling applications.

Related to the chip thickness of milling is the main declination angle of the face milling cutter. The main declination angle is the angle between the main cutting edge of the insert and the surface of the workpiece. There are mainly 45-degree, 90-degree angles and circular inserts. The change of direction will vary greatly with the different entering angle: a milling cutter with a entering angle of 90 degrees mainly generates radial force, which acts in the feed direction, which means that the machined surface will not be subjected to excessive pressure , It is more reliable for milling workpieces with weak structure.
