FIELD: process engineering.
SUBSTANCE: invention relates to instrument making and can be used for production of resilient suspensions of sensors incorporated with DAGs. First, suspension barrel-like blank is made and subjected to thermal cyclic processing. Said blank is machined to get a spider section and hardened in dispersion process. This blanks is subjected to stabilizing ageing at 160-170°C for 6-8 hours and to spark-erosion processing for removal of material from spider bores to ensure depth of required stiffness. Note here that prior to stabilizing ageing, cyclic dispersion hardening is executed. Note also that in first cycle the blank is heated to 745-755°C, held for 15 minutes and water-cooled to 20°C. In second cycle, it is heated to 695-705°C, held for 15 minutes and water-cooled to 20°C. In third cycle, it is heated to 595-605°C, held for 15 minutes and water-cooled to 20°C.
EFFECT: higher fatigue strength.
