Why Is the Rainbow U Type End Mill Recommended for Aluminum Machining?

In CNC aluminum alloy parts processing, customers often encounter problems such as "sticking to the tool", "chip accumulation", and "rough machining surface", which are closely related to the selected tool. The aluminum rainbow U-shaped knife launched by AMG, with its low friction coating and large U-shaped groove structure, effectively solves these problems and has become the first choice for many processing manufacturers.

The following are the four core questions most commonly raised by customers:

1.Why is aluminum easy to stick to knives?

Aluminum alloy material is relatively soft and has high toughness, which easily generates high temperatures during cutting, causing chips to adhere to the tool surface, thereby affecting chip removal and cutting efficiency.

2.Is the rainbow coating really useful?
yes. The AMG colorful U-shaped knife adopts low friction coefficient coatings such as TiB ₂, which can effectively reduce aluminum chip adhesion, improve the surface smoothness of machining, and extend the tool life.

3.What is U-shaped groove design and what are its advantages?
U-shaped groove is a deepened and widened chip removal structure that can quickly remove chips, avoid chip accumulation and repeated cutting, especially suitable for high-speed milling of aluminum parts.

4.Can the high requirement for processing smoothness be met?
of course. This cutting tool adopts sharp cutting edges designed specifically for aluminum materials, with light cutting and low vibration, which can greatly improve the surface quality of machining. It is suitable for precision machining scenarios such as fine contours, shells, and mold cavities.

If your factory is facing chip removal, sticking or smoothness challenges in aluminum alloy processing, the AMG Colorful U-shaped knife may be an efficient solution worth trying.a
