FIELD: process engineering.
SUBSTANCE: invention relates to instrument making and can be used for production of resilient suspensions of sensors incorporated with DAGs. To up the fatigue strength of DAG suspension, its barrel-like blank is, first, made. Said blank is subjected to heat processing and machining. Then, it is subjected to dispersion hardening at 680-700°C for 3-4 hours and stabilisation ageing at 160-170°C for 6-8 hours. Now, it is subjected to EDM processing to remove material from spider holes with ensure the required depth of spiders. Note here that heat processing comprises thermocyclic quenching performed at three steps. Note also that every cycle comprises heating to 900-920°C for 2 minutes and cooling in water 20°C.
EFFECT: higher fatigue strength.
