The cutting characteristics of aluminum alloy : lower strength and hardness than copper, good cutting process; easy to stick to the knife during processing, forming built-up edge; the structure is not dense enough, it is difficult to obtain a small surface roughness value; It is easy to cause deformation during processing, and the surface of the workpiece is also easy to be scratched or scratched; the coefficient of linear expansion is larger than that of copper, which affects dimensional accuracy.
Compared with other difficult-to-machine materials, the processing efficiency is higher in actual production.
Walter offers solutions for machining aluminum alloys: Walter PrototypSky·tec TM (pictured below) is a high performance, high efficiency tool. Compared to general tools, this series of tools can increase the processing efficiency by twice, especially in the processing of aluminum alloy cavity.
Walter PrototypSky·tec TM cutter
The knife has a 25° or 30° helix angle; the polishing edge reduces the possibility of chip formation, even with a reliable chip removal rate when machining deep pockets; CRN coating with optional cutting edge; special RAPAX roughing form; The system, axial and radial bore design, can be supplied with a moderate amount of cutting fluid; the treated smooth surface makes machining more reliable and has high torque. Walter Prototyp Sky·tec TM is particularly suitable for processing soft metals with axial and radial cooling channels, making it ideal for machining deep cavities.
