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 240 – 1000 mm diameter
  • Down to 240 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

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

Adjustable VKS wear edge milling machine

The VKS-A is the latest addition to our air-driven range of wear edge milling machines. The VKS- A is a workshop version of the traditional VKS unit which covers all 2-stroke engines from 32 to 98 cm bore. The VKS-A consists of one main unit and a range of adjustable arms which are easy to change in-situ, as needed.

The VKS-A is easy to adjust to fit the size of 2-stroke engine liners, thus removing the previous need for workshops to have one VKS per liner diameter.
