The valve body is one of the key parts in the solenoid valve products, which mainly plays the role of seal. Due to the airtight index, the tiny arc structures of the valve port are complicated, which causes the high requirements of dimensional accuracy, geometric tolerance and the surface roughness of the product and difficulty of machining and inspection. Traditional processing method can not meet the demand of batch and rapid production. This paper presented a new method of precision machining and inspection for tiny arc, which realized the precision machining and nondestructive evaluation of Ra0.2 roughness and R0.2mm arc surfaces of valve bodies with GYJ130 soft magnetic alloys. The processing methods greatly reduced the requirements for the skill level of operators. The experimental results showed that the machining efficiency of valve body was increased at least three times, and the qualified rate was increased from 60-70% to more than 96%, while the cost of production and material were reduced proportionally.
