But modern machining, has no strict distinction between the T and G class, but in different types of processed materials and processing conditions, different ways such as the use of different materials, and with appropriate coating, to reduce the cost requirements.Cutting parameters need to be selected according to different cutting occasions and different materials to be machined.
In general, T alloys are mainly used to process ferrous metals, because T alloys contain Ti elements (solid solutions), which can effectively reduce the flank wear and wear resistance of the crater, thereby increasing the tool life;G alloy is mainly used to process non-ferrous metals and non metals, because the G alloy can achieve more sharp tool tip and reduce the cutting force effectively.
YT for steel, steel castings, aluminum parts, not shock resistance. YG is used for rough cast iron parts, cast iron parts, shock resistance and high temperature resistance.
