How to grind the end milling cutter correctly?


The end milling cutter is a machine tool tool, which is usually used in horizontal milling. Its outer circle and the two end faces close to the outer circle have cutting edges, so it is called a three sided edge. The one with inserted teeth has an integral one. W18Cr4V is commonly used as the material, and there are nearly 100 kinds of specifications according to the diameter and width (thickness). When in use, the cutter is installed on the cutter bar of horizontal milling, and of course, it can also be installed on other machine tools, generally used for milling grooves and steps.
The end milling cutter has three cutting edges with back corners, which are sharp and easy to cut. Its shape is like eating "there is a round hole in the middle of the pancake". Its outer circle and the two end faces close to the outer circle have cutting edges, so it is called three sided edge. The main cutting edge of the three side milling cutter is distributed on the cylindrical surface of the milling cutter, and the auxiliary cutting edge is distributed on both ends of the cutter. When in use, the cutter is installed on the cutter bar of horizontal milling, which can also be installed on other machine tools, generally used for milling grooves and steps.
The shape and use conditions of the end mill are quite different. The three side milling cutter is called end milling cutter. The carbide three side milling cutter can be grinded with a grinder. Our company uses a tool grinder of Tuol Machinery, and the grinding effect is very good. The disc milling cutter is like a saw tooth at the outer diameter of the disc. The reason why it is called a three sided edge is that both the front and back sides of the cutter teeth and the front face of the cutter teeth have cutting edges, in addition to the application of processing steps and grooves.
Improve the dynamic balance of end milling cutter: it can greatly help to improve the stability of three side milling cutter. Because the unbalance of the tool will generate an additional radial load on the spindle system, which is proportional to the square of the speed. Increasing the dynamic balance of the tool can significantly reduce the centrifugal force.
