Title:

A Fixture for Honing of Epitrochoidal Profile Components and Honing Process thereof
Value Proposition:

Elements of Invention
Crescent-shaped fixture is capable of producing cross-hatch marks on the cylinder
surface to achieve Ra values of about 0.3 microns for retaining sufficient lubricant oil in
the engine cylinder.
Summary Application:

CRESCENT-SHAPED FIXTURE FOR HONING OF EPITROCHOIDAL PROFILE COMPONENTS
Technical Problem Addressed

  • Solution to honing of complex geometry like wankel engine
  • Avoids skilled Man-power
  • Reduces honing time and overcomes cumbersome honing operations requiring high operating costs
  • The lightweight aviation sector UAV's
  • Automobile sector
  • Compressors and pumps Industries
Advantages:
  • Fixture converts the epitrochoidal shape into a circular one making honing simple
  • Invention provides simple, adaptive, cost effective and faster honing for the wankel
    engine
  • User friendly Fixture with compact design
  • Eliminates the need for a special purpose machine
