Tungsten carbide milling cutters are generally mainly used for CNC machining centers and CNC engraving machines. It can also be installed into an ordinary milling machine, and it is also suitable for high-speed machining, tungsten carbide milling cutter is a tool made of tungsten steel, and the hardness is also leveraged, so how to use tungsten carbide milling cutter correctly?

 When the tungsten carbide milling cutter is performing climb milling (also known as co-milling), the feed direction of the workpiece is the same as the rotation direction of the tungsten carbide milling cutter in the cutting area.  

The chip thickness is gradually reduced from the beginning until the end of the cut is lowered during perimeter milling; In conventional milling (also known as reverse milling), the workpiece is fed in the opposite direction to the direction of rotation of the cutter in the cutting area. The chip thickness can start with 0 plus and then gradually increase as the cutting process progresses. This is conventional milling, where the tungsten carbide cutter insert starts cutting at zero chip thickness, which creates a high cutting force that pushes the gap between the tungsten carbide cutter and the workpiece to increase more and more.  

The tool material (carbide, coating, etc.) is selected according to the material to be machined (e.g. steel, aluminum), the cutting edge profile and parameters (number of edges, helix angle) are determined by process (roughing/finishing), and the machine performance is matched (spindle power, shank type), and finally the cutting speed, feed and depth of cut are optimized.

When using tungsten carbide milling cutters, it is necessary to select the appropriate speed, feed and depth of cut according to the material to be processed (such as steel, aluminum), keep sufficient cooling (preferably internal coolant or spray), avoid overload and vibration, and regularly check tool wear to ensure machining accuracy and life.

According to the characteristics of the material to be machined (hardness, toughness, etc.), the type of machining (rough/finishing) and the performance of the machine, the appropriate tool material (HSS/cemented carbide/ceramic, etc.), geometric parameters (number of edges, angle) and coating are selected, and the cutting parameters (speed, feed, depth of cut) are optimized.
