Portable machine for removal of wear edges in cylinder liners

The VKS Wear edge milling machine is a pneumatically driven, portable machine designed to remove wear edges in cylinder liners. It is easily adjustable for different wear edge positions and due to its wheel-mounted design highly accurate, minimising the risk of accidental damage of liners, a frequent occurrence with manual grinding methods. The removal of wear edges minimizes piston pulling time and saves piston rings and liners, increasing engine efficiency. With the VKS the complete removal of a wear edge takes no more than 25 minutes and in most cases less, depending on diameter.

  • Applicable for liners 280 – 980 mm diameter
  • Down to 250 mm diameter depending on engine type.
  • Perfect wear edge removal in 15 – 25 minutes depending on diameter
  • Shortens piston pulling time and saves piston rings and liners
  • Easily adjustable for different wear edge positions
  • Air driven
  • Workshop and onboard versions available

Available for several engine makers, such as: Bergen, Caterpillar, MAN DIESEL, Sulzer, Wärtsilä, etc.
