Description

Technical Field

[0001] The utility model belongs to the technical field of milling cutter spindles, and particularly relates to a liftable milling cutter spindle. Background Art

[0002] In many machines with rotating spindles, in addition to rotating, the spindle also needs to move axially to change its horizontal position or height position. For example, in a sheet grinding and polishing machine, during the production and processing of stone sheets, in addition to the front side that needs to be ground and polished, the bottom side also needs to be ground and polished. When grinding and polishing the bottom side, in the existing grinding and polishing machines, the grinding and polishing blocks for grinding and polishing the bottom side are arranged on the spindle at a fixed height. After the grinding and polishing blocks are worn out after a period of use, they cannot make good contact with the stone sheets, which directly affects the grinding and polishing effect, and it is even impossible to adjust according to the required roughness of grinding and polishing.
