FIELD: process engineering. ^ SUBSTANCE: invention relates to surface plastic deformation, particularly, to breeching and hardening by cold-working of part surface. Part is placed on cutting machine or robot. Impact head is used that is held back in the state of rest by magnetic induction flux B1 with no excitation current I2, and. At least, one coil arranged inside said magnetic flux B1 or the other induction magnetic flux B2. Note here that variable or pulsating current 12 with controlled constant component or without it is fed via windings of, at least, one said coil. Said current I2 provides adjustable frequency and impart head impact frequency to make impact frequency crossing zero from workpiece surface to be variable. ^ EFFECT: possibility to machine 3D surfaces, precision of impact head positioning. ^ 11 cl, 2 dwg |
