CNC milling machine operation matters needing attention
When milling complex workpieces, the use of CNC milling cutters should pay attention to the following issues. 1. Clamping of the end mill If water-insoluble cutting oil is used during cutting, a layer of misty oil film will be attached to the inner hole of the tool holder. When there is an oil film on both the tool holder and the tool holder, it is difficult for the tool holder to firmly clamp the tool holder. It is easy to loosen and fall. Therefore, before the end mill is installed, the shank of the end mill and the inner hole of the tool holder should be cleaned with cleaning fluid, and then the installation should be carried out after drying. 2. Vibration of the end mill Due to the tiny gap between the end mill and the tool holder, the tool may vibrate during the machining process. Vibration will cause uneven cutting of the circumferential edge of the end mill, and the cutting and spreading amount will be larger than the original value, which will affect the machining accuracy
