CNC Turning Anodized Aluminum

2) Selection of hole machining tools. CNC machine tools generally do not have a drilling die. Due to the rigidity of the drill and poor cutting conditions, the diameter D of the drill should meet the condition of L/D≤5 (L is the drilling depth); before drilling, use the center drill to locate, To ensure the positioning accuracy of hole processing; a floating reamer can be used before fine reaming, and the hole should be chamfered before reaming; when boring, a symmetrical multi-blade boring head should be used for cutting to balance the boring vibration; Coarse and shorter shank to reduce cutting vibration. In economical CNC machining, since the sharpening measurement and replacement of the tools are mostly performed manually, the occupancy is relatively long. Therefore, the arrangement order of the tools must be reasonably arranged.
