This tool is recommended for the roughing of additive manufacturing and mold overlay surfaces. 2.Please use machines and holders that are rigid and highly accurate. 3. The values listed above are for reference. Please set the cutting condition in accordance with the actual machining environment.
4.Please reduce the feed rate when the depth of cut is greater than specified. 5. Please adjust the cutting condition when the overhang length is longer. 6. Please use a suitable fluid with high smoke retardant properties.
7. During dry (no fluid) milling, please use air blow to remove disposable chips from the milling area and to eliminate chip packing. 8. Please use water-soluble coolant when machining stainless steel, cobalt-chromiumalloy, titanium alloy, and Ni-based alloy. 9.Tool runout should be kept to a minimum for maximum accuracy. 10. When the cutting load fluctuates in areas such as the corners, please reduce the rotational speed. 11. If Ar is greater than 0.5Dc, there may be a cusp in the machined surface.
