Typical sharpness measurements from this machine
  • Requires only semi-skiilled labour with minimal training
  • Consistent, but adjustable knife edge angle between 20° and 60°
  • Optional “Gothic Arch” edge profile can be produced
  • Use of Cubic Boron Nitride abrasive avoids the need for both a grinding and honing operation, eliminated the need to redress the wheels
  • Low heat generation, which doesn’t need coolant, making a more comfortable operational environment without the loss of blade hardness. This allows the edge to remain fully hardened and not become softened giving maximum blade edge life, thisi as much as 50more than many other sharpeners
  • Easy to maintain as the grinding wheels do not need redressing or regular adjustment
  • Safe operation – grinding wheels do not break as they are of coated steel construction
  • Higher grinding speeds means fast operation without edge burning giving improoved cutting edge life
  • Recoatable grinding wheels keep consumable costs low
  • Can be automated by use of robotic manipulation system
  • Low noise level
  • A range of abrasive grit sizes are available to suit different knife uses
  • Optional variable speed on V 100 and variable speed as standard on V 140

The double spiral interlock grinding wheel sharpening system is used in the machine, which is designed for sharpening in either the knife manufacturing plants of high volume re-sharpening units

In the knife re-sharpening environment, the equipment can easily be adjusted to provide a hollow grinding process for well used blades where the edge has become too thick or if the user prefers that type of blade edge.
