Why do aluminum materials have burrs when cut?

1. Incorrect tool selection directly leads to burrs
Aluminum belongs to plastic materials and is prone to sticking during cutting. However, many companies still use ordinary steel cutting tools, which is a common cause of burrs:

*Unreasonable number of teeth on the cutting tool: Excessive number of teeth can lead to poor chip removal, and aluminum chips melted from the aluminum material will adhere to the blade, forming chip lumps. During cutting, the surface of the work-piece is constantly scraped, resulting in continuous burrs; If the number of teeth is too small, it will lead to excessive cutting per tooth, intensified tool vibration, and the formation of irregular burrs.

*Mismatched tool material: Ordinary high-speed steel cutting tools have insufficient hardness, and wear out quickly when cutting aluminum materials. The blade quickly becomes dull, and blunt cutting will forcefully tear the surface of the aluminum material, forming severe tearing burrs; Uncoated cutting tools are also prone to bonding with aluminum materials, exacerbating the problem of sticking.

Chuda Solution:
For aluminum cutting, we recommend using a special aluminum saw blade made of hard alloy. This type of saw blade features a large rake angle and a large chip groove design, with teeth that are suitable for aluminum cutting needs. Combined with a special coating, it can effectively reduce the occurrence of sticking and chip buildup. The special aluminum saw blade that comes standard with the Chuda fully automatic aluminum cutting machine has been repeatedly tested and optimized, resulting in significantly improved blade sharpness and chip removal performance, reducing the risk of burrs from the source of the tool.
