4 Flute Corner Radius End Mill in the actual processing
 Mar 25, 2021|View:1130

4 Flute Corner Radius End Mill is a very common type of milling cutter in CNC milling, the structure of the product, the cutting edge on the cylindrical surface is the main cutting edge, the end face is distributed with a secondary cutting edge, the main cutting edge is generally spiral teeth, which can increase the cutting smoothness and improve machining accuracy. The main cutting edge is generally designed as spiral teeth, which can effectively increase the cutting smoothness and improve the machining accuracy of the machine. The endface edge is mainly used to process the bottom plane perpendicular to the side. It is mainly used for flat milling, groove milling, step surface milling and profiling milling.


4 Flute Corner Radius End Mill


4 Flute Corner Radius End Mill has four edges with back angle, sharp edge and light cutting. 4 Flute Corner Radius End Mill, can be divided into straight four-sided edge and staggered four-sided edge. It is mainly used in horizontal milling machine to process the step surface and shallow groove through one or both ends. In addition to the main cutting edge on the circumference of the milling cutter, there are also secondary cutting edges on both sides, which improves the cutting conditions, increases the cutting efficiency and reduces the surface roughness value.

For 4 Flute Corner Radius End Mill, generally speaking, if the number of edges of the end mill is small and the chip holding slot is large, the chip discharge can be smoother, the cross-sectional area of 4 Flute Corner Radius End Mill is smaller, the rigidity of the tool body is lower, and the tool body is prone to bending during cutting. If the number of edges increases and the cross-sectional area of the workpiece increases, the rigidity of the tool body will be improved, but the chip holding tank will become smaller and the chip holding force will be reduced, which will easily lead to chip blockage and reduce the surface finish of the workpiece. The shorter the cutting edge, the greater the rigidity of the tool body and the better the cutting performance.4 The rigidity of the Flute Corner Radius End Mill is inversely proportional to the third power of the edge length. Therefore, if the edge length is doubled, the rigidity of the 4 Flute Corner Radius End Mill will be reduced to 1/8 of the original.


Role of End Mills


In the actual company processing, most of the customers use 4 Flute Corner Radius End Mill to process flat surfaces, steps, etc. The 4 Flute Corner Radius End Mill uses a right-handed, right-cutting spiral tooth, so that chips are discharged from the front end of the cutter when processing the material, and the four-flute end mill has a better chip removal effect. The 4 Flute Corner Radius End Mill has a better chip removal effect and increases the cutting front angle to reduce the amount of chips and make it easier to cut the material, so the 4 Flute Corner Radius End Mill is used in more industrial fields such as mold processing, machine tool processing and parts production.
