A four-edge coated milling cutter is a common type of milling cutter with four cutting edges, usually used for milling machining. The cutting edge of the coated milling cutter is coated with one or more layers of wear-resistant material to improve cutting efficiency and extend service life.

The four-edge coated milling cutter is suitable for machining various materials, such as steel, cast iron, non-ferrous metals, etc., especially for machining various complex parts and surfaces. Due to its fast cutting speed and large cutting depth, the processing efficiency can be greatly improved.

When using a four-edge coated milling cutter, it is necessary to pay attention to the installation and adjustment of the tool to ensure that the concentricity, perpendicularity and rigidity of the tool and the machine spindle meet the requirements. At the same time, it is also necessary to select the appropriate cutting parameters according to different processing materials and process requirements, such as cutting speed, cutting depth and feed speed.

In short, the four-edge coated milling cutter is an efficient, high-precision, high-reliability milling tool, which is widely used in the field of machining.
