Typical sharpness measurements from this machine

• - Requires only semi-skilled labour with minimal training
• - 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.
• - Recoatable grinding wheels keep 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.
