安装说明 Assembly Instruction | 安装方式采用焊接方法，如果使用一、二、三轮式工程钻头，则需要一、二、三轮配合使用，形成全断面切削，掌背相对筒体的倾斜角度3~5°,安装时注意内外圈钻头的同心度、高低差，焊接时建议牙轮浸入水中，注意焊接温度，避免损坏密封圈。 Welding type,one,two and three rounds are used together to make the full section cutting the angle of inclination of the palm back relative to the cylinder is 3~5 degrees. Pay more attentionto the concentric degree and the height difference of the inner and outer ring bit during installation.It is suggested that the roller bit should be immersed in water and be careful the welding temperature when doing to avoid damage to the sealing. |
