Given the results of numerous studies with the help of specially designed and made quick ultrasonic devices. As a result of studies it is established that the application of the forced tool of ultrasonic oscillations allows you to significantly increase the efficiency of the process threads. When this failed to achieve increase of productivity of process and durability of the cutting tool.</p>Threadultrasound devicetapvibrationsthreadingРезьбаультразвуковое устройствометчикколебаниярезьбонарезание
