In the process of CNC machining, various industrial tools are used. These tools need to adapt to the characteristics of high automation, high efficiency and fast speed of CNC machine tools. From the appearance and shape, it can be divided into flat bottom cutter (End Mill), Corner Radius Cutter and Ball Nose Cutter. Of course, you can purchase all these knives from our Kinbolon website.
The Corner Radius End Mill is between the end mill and the ball nose cutter, which is the one with R on the tip. The bull nose end mill itself is most suitable for high-speed machining, because it has the characteristics that the corners are not easy to crack and the stability of the cutting line speed is unmatched by flat cutters and ball cutters. Therefore, the round nose cutter is mainly used for rough machining, plane finishing and side finishing of mold blanks, especially for rough machining of molds with high material hardness.
We need to choose the appropriate tool according to the specific shape of the workpiece. If the workpiece is large, the surface changes less, there are fewer narrow concave areas, and there are more relatively flat areas, it is strongly recommended to use a bull nose end mill for processing, and then use the secondary roughing method to find the area that needs subsequent processing. If the workpiece is small, the surface changes greatly, and there are many narrow concave areas, a ball cutter can still be used.
Features
1. The cutting speed of carbide corner radius end mill is stable. When the carbide bull nose end mill is milling similar workpieces, the four points can maintain a certain cutting speed, so that the processed surface quality is better than that of the ball end milling cutter. Fast milling speed.
When milling 3D molds, the carbide corner radius end mill has another advantage, which is incomparable to the ball nose cutter. The cutter itself will vary greatly with the contact position with the workpiece and the cutting speed, so the quality of the processed surface is unstable. Although the same is true for nose knives, the change in cutting speed is not as large as that of ball knives. Therefore, the quality of workpieces processed with carbide bull nose end mill is of course stable.
2. The machining efficiency of carbide corner radius end mill is high. In addition, round nose cutters have better processing efficiency than ball cutters and end mills, especially in rough machining, because the bottom of round nose cutters is flat, and the horizontal cutter distance of carbide bull nose end mill can be used more than ball cutters. The knife is bigger. In finishing, it also has the same advantages as the ball cutter, so the cutter spacing can also be used with a larger value. Therefore, whether the round nose cutter is used for rough machining or finishing machining, it is a very suitable choice.
The difference between the carbide corner radius end mill and the ball cutter in appearance is that it combines the advantages of the ball cutter and the end mill. The bottom of the cutter head maintains the characteristics of the end mill. This design can make it have better milling quality when processing flat workpieces. Although the processing range is relatively small when processing curved surfaces, it is useful for small-angle curved surface processing. Great advantage. At the same time, it does not have the static grinding situation of the ball cutter, so its wear is relatively small and its service life is relatively long. In some small concave areas, due to the blind area of the edge of the round nose knife, the phenomenon of "top knife" will occur, so that some areas cannot be processed, so it needs to be selected reasonably.
If the workpiece is large, the surface change is small, there are few narrow concave areas, and there are many relatively flat areas, it is strongly recommended to use a carbide bull nose end mill for processing, and then use the secondary roughing method to find the area that needs subsequent processing . If the workpiece is relatively small, the surface changes greatly, and there are many narrow concave areas, a ball end cutter can still be used.
