Тhe accuracy of the holes in the electro - mechanical processing with a high-temperature strip tool is achieved by the development of original tooling. The article presents technical solutions of tool and technological equipment to ensure the accuracy of holes in the implementation of processes of electromechanical processing with a high-temperature strip source. The results of measurements on cylindricality of the hole of the sleeve bearing of the upper head of the connecting rod of the Yaroslavl Engine Plant engine after volumetric electromechanical mandrel are presented, confirming the effectiveness of using the developed tooling.

This paper addresses problems connected with machine engineering for compaction of powder materials by vibration. The authors present an engineering solution of disperse granular material compaction in pone operating cycle of a compacting equipment. The structural layout of a vibratory compactor involves a polyharmonic oscillation exciter. Some research findings on the compaction process of granular material with the proposed facility are given, and its efficiency is compared with a compacter with a harmonic oscillation exciter. The research shows the promising nature of this method, while the polyharmonic oscillation exciter expands the application range of vibratory equipment in many industries.
