Yes. There is no need to add cutting fluid after CNC lathe turning iron parts. The cast iron cutting fluid is a water-soluble fully synthetic cutting fluid with high lubrication and stable biological properties. Zinc alloy turning is not an iron part, so CNC lathe turning zinc alloy requires adding cutting fluid. . CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting internal and external cylindrical surfaces of shaft parts or disk parts, internal and external conical surfaces with any cone angle, complex rotating internal and external curved surfaces, and cylindrical and conical threads. It can also perform grooving, drilling, reaming, and reaming. Holes and borings, etc.
