To achieve automatic cutting of cast stainless steel risers, a brazed diamond saw blade is developed, and cutting 304 stainless steel tests are performed on the CNC machine tool. The temperature of the blade-debris contact zone for both dry and wet cutting is measured. The vibration signal during cutting is collected and analyzed. Wear characteristics and mechanism of diamond grinding particles and processed surface quality are studied. The results indicate that the cutting temperature was low, the vibration amplitude of the system was small and the surface quality of the cut was high during wet automatic cutting of 304 stainless steel. Low cutting temperature suppressed chemical wear of diamond abrasive grains, and small vibration improved the surface quality of the cut. However, poor results were achieved when dry cutting stainless steel. It is feasible that 304 stainless steel was wet cut using brazed diamond saw blades on CNC machine tool.
