How to Grind the Face Milling Cutter Correctly
The three-face milling cutter is a standard machine tool. It is usually used in horizontal milling. Its shape is like a "round hole in the middle of the biscuits". Its outer circle and the two end faces near the outer circle have cutting edges. Therefore, it is called a three-sided blade. There are inserts and integral ones. The material is commonly used W18Cr4V. There are nearly a hundred specifications according to the diameter and width (thickness). When in use, the knife is installed on the shank of the horizontal milling machine, of course, it can also be installed on other machine tools, generally used for milling grooves and steps.
Three-face and face milling cutter has a relief angle for all three cutting edges, the cutting edge is sharp, and the cutting is brisk. Its shape is like "a round hole in the middle of the biscuits". Its outer circle and the two end faces near the outer circle have cutting edges, so it is called a three-sided edge. The main cutting edges of the tri-face milling cutter are distributed on the cylindrical surface of the milling cutter, and the secondary cutting edges are distributed on both end surfaces. When in use, the knife is installed on the shank of the horizontal milling machine. Of course, it can also be installed on other machine tools. It is generally used for milling grooves and steps.
The shape and use conditions of the “face milling cutter” and the “end milling cutter” are completely different. The face milling cutter is called the end mill. The hard alloy face milling cutter can be ground with a grinder, and our company uses Tuol The mechanical tool grinder has a very good grinding effect. Disc type milling cutters are like serrations at the outer diameter of the disc. Why is it called a three-sided blade because the front and back sides of the tooth and the vertical surface have an edge. In addition to the application of processing steps and grooves.
Improve the dynamic balance of the face milling cutter: it can greatly help to improve the safety of the face milling cutter. Because the unbalance of the tool will produce an additional radial load on the spindle system, its magnitude is proportional to the square of the speed. Improving the dynamic balance of the tool can significantly reduce the centrifugal force and improve the safety of high-speed tools.
How to grind the three-face milling cutter: Grind the three-face milling cutter with a tool grinder, and use a bowl-shaped grinding wheel to grind the two side relief angles of the three-face milling cutter and the main relief angle of the cutting edge. Generally, the relief angle is the relief angle of the tooth of the outer circle. Carbide three-face and face milling cutters can be grinded with a grinder. Our company uses a tool grinder from Thor Machinery, and the grinding effect is very good.
