Dohre AEX Series end mills are developed for aluminum alloy and non-ferrous material machining, including 6061 aluminum, 7075 aluminum, aluminum-silicon alloy, magnesium alloy, copper alloy, and engineering plastics.
For aluminum machining, tool sharpness, flute design, chip evacuation, and anti-adhesion performance directly affect surface finish, burr control, and tool life. AEX Series aluminum end mills are designed to help reduce built-up edge, improve chip flow, and support stable cutting performance in high-speed CNC machining.
As a carbide end mill manufacturer, Dohre provides AEX square end mills, ball nose end mills, corner radius end mills, single flute end mills, and high polished aluminum end mills for different aluminum machining requirements. Custom dimensions, coating options, flute designs, and OEM orders are also available for industrial customers.
AEX Series for Aluminum and Non-Ferrous Machining
Aluminum is soft, ductile, and easy to adhere to the cutting edge during machining. If the tool geometry is not suitable, common problems include chip packing, built-up edge, burrs, poor surface finish, unstable tool life, and excessive cutting heat.
AEX Series end mills are developed for these aluminum machining challenges. The series focuses on sharp cutting performance, smooth flute design, efficient chip removal, and stable cutting quality for aluminum and non-ferrous materials.
AEX aluminum end mills can be used for different aluminum machining needs, including:
• Slotting
• Side milling
• Pocket machining
• Shoulder milling
• 3D contouring
• Curved surface finishing
• High-speed aluminum cutting
• High-gloss aluminum finishing
• CNC router aluminum and soft material machining
Suitable materials include 6061 aluminum, 7075 aluminum, aluminum-silicon alloy, magnesium alloy, copper alloy, engineering plastics, acrylic, PVC, MDF, and other non-ferrous or soft materials.
How to Choose the Right AEX End Mill
Different aluminum machining tasks require different tool geometry. Instead of choosing only by tool name, buyers should select the tool according to cutting method, surface requirement, chip evacuation condition, and workpiece material.
| Machining Requirement | Recommended AEX Tool Type | Best Use |
|---|
| Slotting and flat bottom machining | Square / flat end mill | Slots, pockets, flat surfaces, side walls |
| Curved surface finishing | Ball nose end mill | 3D contouring, curved profiles, mold surfaces |
| Shoulder and side-wall finishing | Corner radius end mill | Stronger corner protection and stable side-wall machining |
| High-speed chip evacuation | Single flute end mill | CNC router cutting, large chip space, soft materials |
| High-gloss aluminum surface | High polished end mill | Appearance parts, low burrs, reduced tool marks |
| Special aluminum parts | Custom AEX tools | Special diameter, flute length, coating, or geometry |
For general slotting and side milling, square or flat end mills are usually the first choice. For 3D surfaces and curved profiles, ball nose tools are more suitable. For shoulder machining and longer tool life at the corner, corner radius end mills offer better edge protection. For high-speed cutting and soft materials, single flute tools provide larger chip space. For appearance parts and high surface quality, high polished aluminum end mills are more suitable.
Key Cutting Problems in Aluminum Machining
AEX Series is designed around the typical problems found in aluminum milling.
Chip Sticking and Built-Up Edge
Aluminum chips can easily stick to the cutting edge or flute surface. A smoother flute surface and suitable cutting geometry help chips leave the cutting area more easily.
Chip Packing in Slots and Pockets
When chips cannot evacuate smoothly, they can be recut or packed inside the pocket. This can cause tool wear, poor surface quality, and unstable cutting.
Burr Formation
Sharp cutting edges and lower cutting resistance are important for reducing burrs on aluminum parts, especially in slotting, side milling, and profile finishing.
Surface Finish Instability
Aluminum parts often require clean surfaces, especially for electronic components, automotive parts, appearance parts, and precision components. Stable geometry and edge consistency help improve finishing quality.
Tool Selection Confusion
A square end mill, ball nose end mill, corner radius end mill, single flute end mill, and high polished end mill are not used for the same purpose. AEX Series helps customers choose according to machining scenario instead of only tool shape.
