  • Consistent, but adjustable knife edge angle between 20° and 60°.
  • The double spiral interlock grinding wheel sharpening system is used in the machine, which is designed for sharpening in either the knife manufacturing plants or high volume re-sharpening units.
  • This system, coupled with the high tech abrasive Cubic Boron Nitride (CBN) gives the machine many advantages.
  • Use of CBN abrasive avoids the need for both a grinding and honing operation.
  • Low heat generation, which does not need coolant, making a more comfortable operational environment.
  • 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, low noise level.
  • Higher grinding speeds means fast operation without edge burning. No loss of blade hardness at the tip of the cutting edge, thereby maintaining high edge life.
  • Grinding wheels can be recoated, keeping costs low.
  • A range of abrasive grit sizes are available to suit different knife uses.
  • Dual operation allows both sharpener and hollow grinder in one machine.
  • Can sharpen a wide range of curved and straight machine blades with either single or double bevel edges.

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. Adjustment between sharpening and hollow grinding takes less than 10 seconds and a typical hollow grind time is less than 2 minutes.
