Technical description

The sharpening process is carried out in three stages: phase 1 - endless abrasive tape; phase 2 - upper wheel; phase 3 - movable sisal smoothing disk

General description of the machine:
The W70K machine is used for sharpening cutter knives, but you can also sharpen other knives with the help of additional accessories. We recommend using appropriate equipment for sharpening knives.
The convenient knife attachment system ensures quick, accurate and simple operation during machine operation. Slow rotation of the upperwheel excludes the risk of injury. On the contrary, water cools and prevents overheating of the blade and the blade of the knife. Compared to conventional manual grinding and sharpening methods, the machine and accessories provide more precise sharpening. The equipment of the W70K machine allows you to individually adjust the angle and allows you to sharpen the long edge of the knife. The machine was carefully and reliably manufactured, so all parts have a long service life, and maintenance and care are very simple.
