New Installation for Manufacturing Hard-Machine Details by Electropulse, Electro-Erosion and Electrochemical Processing


Universal installation "Elekta-2" is designed for manufacturing hard-machine details, mostly from tempered alloyed steels and hard alloys by a consequence of electricall methods. Processing is conducted with a single setting up of a detail in a machine and its processing by a chain of methods mentioned below, electrodes-tools and working liquids. The typical sequence of processing is the following: an electro-pulse technology for maximum material removal; electro-erosion technology for the removal of a defective layer and the reduction of the surface roughness; electrochemical technology for the finishing accurate processing and high-quality surface.

Innovative Aspect and Main Advantages

Innovative aspect consists in a chain of electrical methods for mechanical tools processing and their integration in a single universal installation. The main advantages of the proposed installation are the following:

  • Universality and high quality and accuracy of processing
  • Reduction, up to 3-4 times, of the time and cost of details manufacturing and processing
  • Smaller dimensions of the installation and its working space
  • Reduce operating personnel.

The installation is ecologically friendly due to the optimal processing methods that allow less chemical working liquids consumption.

Areas of Application

  • Mechanical tools processing, mostly from tempered alloyed steels and hard alloys.
  • Die-mold and die manufacturing
  • Extrusion form tools
