Wear-Edge Groove Grinding

Using DAN Wear-Edge Groove Grinding Machine, we will remove the wear-edge in way of the top piston ring TDC and produce a groove in order to prevent the buildup of carbon residues and subsequent damage to the piston rings.

The benefits of Wear-Edge Groove Grinding

  • Produce a groove in way of the top piston ring TDC. As the liners wear down increases, a sharp edge will develop at the TDC of the top piston ring, especially in the P-S direction. This edge is removed and a groove milled deep enough to avoid an edge to develop in the future running of the engine.
  • Prohibit the occurrence of built-up carbon deposits in way of the top ring TDC, which may cause damage to piston rings and ring grooves in the piston crown.
