What is the reason for the damage of the cutter head of the milling machine?

The manufacturer of XCMG accessories learned that the cutter head of the milling machine belongs to the vulnerable part of the milling machine accessories, so how is the accessory damaged and how to prolong its service life? Let's follow the manufacturers of XCMG accessories to analyze.
In one case, the user saves the cutter head and uses the cutter head to the limit, resulting in accelerated wear of the cutter base. The other is that the tool holder continues to be used after reaching the wear limit. This practice will cause the normal working condition of the tool head to be damaged, resulting in abnormal damage such as eccentric wear and fracture of the tool head.
1. Abnormal damage caused by bottom cleaning
During the bridge bottom cleaning operation, due to the different depth of the reinforcement laid on the bridge deck, it is easy to mill the reinforcement during milling, resulting in the collapse of the tool tip, the fracture of the tool tip from the tool handle or the falling off of the tool base. In serious cases, after the steel bar is rolled on the milling drum for one week, the milling drum may be entangled, causing the milling drum to be stuck, so that the engine will be overloaded and automatically shut down or other parts will be damaged.
2. Abnormal damage during urban road operation
When paving asphalt on earlier urban roads, some well covers were not lifted and were still buried under the asphalt pavement. During the pavement maintenance milling operation, because the asphalt layer of this kind of pavement is not thick, usually 4cm, it is very easy to have the milling drum planing the well cover, which directly leads to the breakage of some cutter heads, and in serious cases, the cutter base will fall off, and the clinker belt will also be cut.
