Efficient precision machining method and special tools for accelerometer coil framework

The invention relates to an efficient precision machining method and special tools for an accelerometer coil framework. A five-axis numerical control rotary ultrasound method is applied to the machining of the high-precision hard and brittle material blind hole thin-walled accelerometer coil framework, an existing technological process is optimized, the original machining process of adopting two times of clamping to sequentially form an inner hole and an annular groove is optimized to be the machining process of adopting one time of clamping to sequentially machine the annular groove and the inner hole of the part, a special leveling and machining tool is designed, the bonding method is selected as the part clamping method, and a special bonding tool is designed. By the adoption of the efficient precision machining method and the special tools for the accelerometer coil framework, the machining difficulty is lowered, the manufacturing cost is lowered, and the machining efficiency, the machining precision and product percent of pass are improved.
