Sharpness, cutting angle, shape, and profile of the cutting blade have a significant impact on the quality of the produced products. High cutting speeds up to 180 m per second (equivalent to 650 km per hour) and lateral pressures impose significant mechanical load on the cutting blades. Therefore, a polished cutting edge directly influences its resistance to cracking. Manual grinders have versatile applications for all popular cutting blades as well as circular, hand, and other cutting tools. During the grinding process, the cutting tools are securely and precisely held in the attachments, ensuring safe and accurate operations. The result is a long lifespan of the cutting edges. Automatic sharpeners provide precise and accurately curved edges while maintaining the cutting profile and original blade shape throughout the lifespan of the cutting blades. The grinding processes, depending on the machine type, can be performed with minimal manual intervention, ensuring consistently high quality of the cutting blades.
Cup grinding wheel
The cup grinding wheel removes a lot of material very quickly. It is used to easily repair badly damaged cutting tools. Chamfered edges, e.g. on circular knives, are ground on the cup grinding wheel. The required grinding angle is continuously adjustable.
Wet-grinding belt
The wet-grinding belt ensures a very fine cutting tool surface. The profiled rubber contact wheel applies the exact amount of grinding resistance to the knife.
Finned brush
Deburring and polishing of the knives is carried out on the finned brush. The precisely adjusted peripheral speed and the ideally coordinated brush resistance compensate handling errors.
Function disk
Thanks to the patented function disk, the machine is converted in seconds from sharpening sickle shaped cutter knives to linear shaped cutter knives. When changing the knife, a locking mechanism prevents the knife from slewing out unintentionally. It can be changed absolute safe.
Sharpen hand knives
Hand knives are sharpened manually on the wet-grinding belt and deburred and polished on the finned brush.
Grinding circular knives
Circular knives with diameters from 150 – 480 mm are sharpened and deburred on the optionally available circular knife grinding unit.
Grinding belt replacement
When the belt protection cover is opened, the drives are stopped. The tension on the grinding belt is relieved and it can be replaced.
The Universal Wet-Sharpening Machine S 20 is a universal grinding machine for all conventional cutter knives as well as circular knives, hand knives and other cutting tools. Whether for grinding, polishing or deburring – the cutter knives are clamped in attachments at all times and are therefore guided safely and precisely. The result is a long service life of the cutting edges. For the operators, this means: a high degree of safety with minimum effort. The innovative knife guiding carriage enables sharpening, polishing and deburring of cutter knives in one clamping setup. A coolant pump supplies the individual grinding stations with water. The cutting edges cannot overheat when grinding.
