The grinding table is arranged inclined towards the user. The integrated teflon glides reduce the friction between the grinding table and the copy grinding plate to a minimum. The interaction of these ergonomically optimized components enables fatigue-free working and makes the operation simple and safe.
For a comfortable operation, the handles of the copy grinding plate are designed and arranged according to the contour of the cutting edge.
The advantages at a glance
Operation
When sharpening, the sickle-shaped knives are manually guided on a defined path along the grinding wheels. This path is predetermined by the copy grinding plate and matches the knife contour. This ensures retention of the original knife shape.
Copy grinding plate
For grinding the sickle-shaped knives are mounted on a tailor-made copy grinding plate.
Cutting edge angle
The cutting edge angle can be set continuously from 25° – 35°. This is performed by using an angle gauge.
Dressing
Grinding wheels which have become untrue are fast and easily dressed with the HV 146 Truing Device.
Overheating protection
The grinding wheels move through a water bath, preventing the cutting tools from overheating.
