Aluminum Milling Cutter

Cemented carbide is a commonly used tool material in China Zhongyeda aluminum milling cutter factory. It is made of refractory metal carbides (such as tungsten carbide, titanium carbide, etc.) and metal binders (such as cobalt) through powder metallurgy. It has the advantages of high hardness, strong wear resistance, and good hot hardness, and can efficiently process aluminum and aluminum alloys at high cutting speeds. For example, in the milling of aluminum alloy cylinder blocks of automobile engines, cemented carbide aluminum milling cutters can maintain a sharp edge for a long time, stably complete milling tasks, and greatly improve production efficiency.

In order to further improve the performance of cemented carbide milling cutters, coating treatment is often performed on their surfaces. Common coatings include titanium nitride (TiN), titanium aluminum nitride (TiAlN), titanium carbonitride (TiCN), etc. These coatings can significantly improve the wear resistance, corrosion resistance and lubricity of the tool. Taking aluminum titanium nitride coating as an example, it has extremely high hardness and oxidation resistance, which can effectively reduce the friction between the tool and the aluminum material, reduce chip adhesion, thereby improving the quality of the processed surface and extending the service life of the tool. In the processing of thin-walled aluminum alloy parts in the aerospace field, coated carbide aluminum milling cutters can better ensure the dimensional accuracy and surface finish of the parts.

Cermet is a new type of tool material that combines the high hardness and high wear resistance of ceramics with the toughness of metals. For the processing of aluminum and aluminum alloys, cermet aluminum milling cutters have good cutting performance, can achieve high-speed cutting, and generate less cutting heat during the processing, which is conducive to maintaining the dimensional accuracy of the workpiece. In the processing of aluminum alloy housings of some electronic equipment with extremely high processing accuracy requirements, cermet aluminum milling cutters perform well.

Popular introduction to milling cutter types

End milling cutter: End milling cutter is one of the commonly used milling cutter types in aluminum processing. It has cutting edges on the end face and circumference, and can perform a variety of processing operations such as plane milling and step milling. When processing large-area flat surfaces of aluminum plates, end mills can achieve efficient material removal through fast cutting, and the surface quality of the processing is good.

End mills: End mills are mainly used for milling grooves, keyways, and contour processing. The cutting edge on its cylindrical surface can accurately cut aluminum materials and is widely used in the internal structure processing of aluminum alloy parts. For example, when processing heat dissipation grooves on aluminum alloy parts, end mills can rely on their good rigidity and cutting performance to process grooves with precise dimensions and smooth surfaces.

Ball head milling cutter: The end of the ball head milling cutter is spherical and is often used in mold manufacturing, complex surface processing and other fields. In the processing of aluminum alloy molds, ball head milling cutters can accurately mill various complex surface shapes to meet the high precision requirements of molds.

Number of blades and helix angle

Number of blades: The number of blades for aluminum milling cutters has different options such as single blade, double blade, and multi-blade. Single-blade milling cutters have good chip removal performance and are suitable for processing thin-walled aluminum parts or occasions with high chip removal requirements. They can effectively avoid the influence of chip blockage on processing quality. Multi-edge milling cutters have higher cutting efficiency. In mass production, multi-edge milling cutters can improve production efficiency through faster cutting speeds and feed rates.

Helix angle: The size of the helix angle has an important influence on the cutting performance of the milling cutter. A larger helix angle can make the cutting edge cut into the aluminum material more smoothly, reduce cutting force and vibration, improve the surface quality of the processing, and is suitable for fine processing. A smaller helix angle has better chip removal performance, and can quickly discharge a large amount of chips in rough processing to prevent chip accumulation.
