FIELD: machine building.;SUBSTANCE: device contains a casing, acoustic system comprising converter connected with waveguide, at its end ultrasound emitter is installed. The acoustic system is secured coaxially in the internal socket of the hollow piston-rod having two support external cylindrical surfaces with large and small diameters. The support surface of the piston-rod with large diameter is adjoined with the internal cylindrical surface of the casing, and support surface of the piston-rod with small diameter is connected with the internal cylindrical surface of the guide bushing. The guide bushing is installed in the casing and is intended to set force of machining using the pressure transmitter installed in the casing by length adjustment of the closed hydraulic cavity created by the work end of the piston-rod, end of guide bushing, internal cylindrical surface of casing, and external surface of piston-rod with small diameter. On the support surface of the piston-rod with small diameter the compression spring is installed, its one end touches the work end of the piston-rod, and other end touches the4 end of the guide bushing. Rigidity of the specified compression spring k is selected from ratio where p is pressure in closed hydraulic cavity, S is area of work end of the piston-rod, Δ is displacement of the piston-rod under force from side of the machined part surface.;EFFECT: stability of parts batch machining at NC machine.;1 dwg
