Patent Status: 

Patent Filed

Indian Patent Applicaton No: 

2082/DEl/2008

Patent Category: 

Overview: 

This invention the dry and near dry operation electric discharge machining.

Key Features: 

  • A new machine unit which is used to enable performing the dry EDM process on existing EDM machines (which were originally designed for liquid dielectric only).
  • High pressure gas flow is achieved by maintaining a gas flow path from the pressure line to tool through the rotating shaft.
  • The tool holding part is designed so that tools of different sizes can fit without much leakage of gas at the junction between the tool and the spindle-shaft.
  • The motor side -mounted on spindle for continuous feed motion of tool.

Applications: 

The invention can be used as an accessory on an existing EDM (electric Discharge machine) to implement the dry EDM process.
