Commonly used cutter heads for gantry milling machines include high-precision cutter heads, high-speed cutter heads, and heavy-duty cutter heads; corresponding inserts include copper alloy inserts, carbide inserts, and ceramic inserts.
High-Precision Cutter Heads
High-precision cutter heads are typically cast from high-quality cast iron, featuring high surface hardness and a certain degree of wear resistance. They are suitable for high-precision milling operations, such as the machining of mold components and marine parts.
High-Speed Cutter Heads
High-speed cutter heads are manufactured using high-speed steel, possessing high hardness. They are suitable for machining applications involving high cutting speeds, such as in the aerospace, automotive parts, and mold manufacturing sectors.
Heavy-Duty Cutter Heads
Heavy-duty cutter heads are designed for machining workpieces requiring substantial material removal-such as large castings and forgings. These cutter heads typically possess robust deburring capabilities, enabling them to quickly and accurately remove burrs and protrusions from the workpiece surface to achieve superior surface quality.
Copper Alloy Inserts
Copper alloy inserts feature relatively low hardness and low cost. They are typically used for machining parts made of materials such as cast iron, copper, and aluminum, making them suitable for general milling and turning applications.
Carbide Inserts
Carbide inserts possess high hardness and are frequently used for machining high-hardness workpieces, such as mold components. Furthermore, carbide inserts exhibit excellent wear resistance, allowing them to maintain the sharpness of their cutting edges over extended periods of use.
Ceramic Inserts
Ceramic inserts are characterized by ultra-high hardness and an ultra-fine grain structure, which effectively enhances milling precision and surface quality. However, ceramic inserts are relatively expensive and are susceptible to damage caused by torsional forces.
