Ceramic end mill
Milling cutter is a rotary cutter with one or more teeth for milling. When working, each cutter tooth intermittently cuts the residual amount of the workpiece. The milling cutter is mainly used for processing planes, steps, grooves, forming surfaces and cutting off workpieces on a milling machine. The SiAlON material further improves the chemical stability based on the high strength and high toughness of silicon nitride. Therefore, it is especially suitable for high-speed cutting of nickel-based heat-resistant alloys (superalloys).
In turning and milling, the high temperature brought by the high-speed cutting of difficult-to-machine materials makes cemented carbide no longer meet the production and processing requirements. Therefore, the silicon nitride ceramic material with a hardness between the super hard material and the ordinary hard alloy has become one of the important metal processing tool materials.
In addition, silicon nitride ceramics have good high temperature strength, high temperature hardness, thermal shock resistance and very competitive prices, making silicon nitride materials the first choice for cutting tools.
