In the last issue of《Dimensional classroom》Li，Xiaowei took us to learn the rear door lifting speed regulation mode of the two-meter milling drum.，Have you learned?？Today, Xiaowei will introduce new knowledge to you.。You know that when the device is working，Is the milling drum divided into two different modes of upper cutting and lower cutting according to the different cutting directions?？So what are the advantages of these two different modes in application?？Click on the video to increase your knowledge together.！

As a core component in cutting material，The milling drum has a great influence on the construction quality and efficiency of the equipment.，The milling drum can be divided into two working modes of upper cutting and lower cutting according to the different cutting directions of the road surface.。Upcut mode，Generally speaking, the milling drum cuts the road surface from bottom to top.，The advantage is that this mode consumes relatively little fuel and bit wear；

Undercut mode，The milling drum cuts the pavement from top to bottom，Like inCRA series of recycling machines adopt this mode when carrying out recycling operations.。Its advantage is that it can effectively avoid the appearance of large materials.，Control the particle size of the milling material，So that that gradation of the regenerate material is effectively controlled。

《Dimensional classroom》It is a video column produced by Wittgen China Technology and Training Center to introduce equipment operation and precautions.，Launch on a regular basis，I hope you will continue to pay attention.。In addition，If you have any questions you want to know, you can also send us a bullet screen or leave a message.。
