There are many factors that affect the quality of CNC milling cutter, such as the material, geometry, coating, and wear of the cutter. Here are some general guidelines to help you judge the quality of CNC milling cutter:

Material: The material of the milling cutter should match the material of the workpiece. For example, high-speed steel (HSS) cutters are suitable for low-carbon steel, aluminum, and plastic, while cemented carbide (CC) cutters are suitable for high-carbon steel, stainless steel, and titanium. The material of the cutter should also have high hardness, toughness, and wear resistance. Our QT Tools use imported raw material to produce the high quality carbide end mill.

Geometry: The geometry of the milling cutter includes the number, shape, angle, and helix of the cutting edges. The geometry of the cutter should be optimized for the machining task, such as roughing, finishing, contouring, or pocketing. For example, more cutting edges can increase the feed rate and reduce the cutting force, but they may also increase the heat and vibration. The shape of the cutting edges can affect the chip formation and removal, as well as the surface finish. The angle and helix of the cutting edges can affect the cutting force, torque, and stability.

Coating: The coating of the milling cutter can enhance the performance and extend the life of the cutter. The coating can reduce the friction, heat, and wear of the cutter, as well as improve the corrosion resistance and lubricity. The coating of the cutter should be selected according to the material and condition of the workpiece. For example, titanium nitride (TiN) coating is suitable for general-purpose milling, while titanium carbonitride (TiCN) coating is suitable for high-speed and hard milling. Our QT Tools constantly innovating coatings, determined to find the best coating for your product processing

Wear: The wear of the milling cutter is inevitable during the machining process. The wear of the cutter can affect the accuracy, quality, and efficiency of the machining. The wear of the cutter can be measured by the flank wear, crater wear, notch wear, and chipping of the cutting edges. The wear of the cutter can be reduced by selecting the appropriate cutting parameters, such as the cutting speed, feed rate, depth of cut, and coolant. The wear of the cutter can also be detected by monitoring the cutting force, power, temperature, and sound.
