Material Selection for Milling Cutters

Highspeed steel (HSS) is suitable for softer materials (such as aluminum and lowcarbon steel) and lowspeed processing. Carbide cutters are better for harder materials, offering greater wear resistance. Ceramic milling cutters are ideal for hightemperature environments and superhard materials. Selecting the right material should consider the workpiece hardness, temperature requirements, and cutting conditions.

Controlling cutting speed and feed rate can reduce tool wear. Using the appropriate coolant can lower processing temperatures and remove chips effectively. Regularly inspect the cutting edges and regrind when necessary to extend tool life.

TiAlN coating is suitable for highhardness materials and hightemperature cutting. TiCN coating offers excellent wear resistance, ideal for stainless steel and highhardness steels. DLC coating reduces friction and is suitable for highadhesion materials like aluminum and copper. Choose the appropriate coating based on material and processing conditions to improve tool performance.

Flatend milling cutters are suited for flat and side milling. Ballend cutters are ideal for 3D surface machining, such as molds and grooves. Roundnose cutters combine the benefits of flat and ballend cutters, making them ideal for corner cutting and effectively reducing edge chipping.

Certain carbide and ceramic milling cutters are suitable for highfeed and highspeed machining. Properly set the feed rate and cutting depth, and ensure stable machining conditions to prevent excessive wear or chipping of the tool.

For aluminum alloys, use high speed and low feed to improve efficiency. For materials like stainless steel, reduce cutting speed to avoid overheating. For die steel, increase cutting speed and cooling to ensure stable processing.

Milling cutters can be reground to extend their life, but this should be done by professionals to maintain the tool’s precision and durability. If the cutting edge is severely worn, it is recommended to replace the tool.

Many manufacturers offer custom tool services, typically tailoring tool materials, sizes, and edge shapes based on customer needs. Pricing depends on tool size, material, and design complexity.

Chipping of the cutting edge may be caused by excessive feed or cutting depth; it is recommended to adjust the cutting parameters. Poor surface roughness may result from tool wear or high cutting speed. Consider regrinding the tool or lowering the cutting speed.

Manufacturers typically offer aftersales services, including technical consultation and tool issue analysis. To prolong tool life, it is recommended to clean tools regularly, check the condition of the edges, and maintain them based on usage. Some manufacturers also provide recoating or regrinding services.
