Description

Technical Field

[0001] The invention relates to the technical field of horizontal machine tools, in particular to a horizontal numerical control machining machine tool. Background Art

[0002] When engraving large-diameter flower rollers or printing rollers, horizontal roller engraving machines are generally used for processing. When the weight of the roller to be processed is small, the roller is generally clamped between the top shaft and the drive seat, and the roller is in a suspended state. When the weight of the roller to be processed is large, the top shaft and the drive seat are difficult to effectively support the roller, and additional support is required for the bottom of the roller, such as support wheels or rollers. However, debris will adhere to the outer surface of the roller during processing. The debris is transferred with the roller to between the roller and the support, which will lift the roller or squeeze and damage the surface of the roller, which is easy to affect the stable operation of the roller. Although the existing horizontal processing machine tools can also clean the iron filings on the surface of the roller, they mostly use flushing or blowing cleaning methods.
