Advantages
Knife holding fixture SP 114
The knives are clamped on the knife holding fixture by a vacuum. Multiple knife shapes and sizes are assembled in groups and can be ground with only one knife holding fixture. In less than 1 minute the machine is changed to a different knife shape.
Knife magazine
The knife magazine has space for 8 knives. It can optionally be extended to 16 knives.
Abrasives
For the sharpening process water resistant wet-grinding belts are used. Up to 40 cutter knives (500-750 l) can be ground with one belt. The operator controls the grinding pressure via touchscreen.
Polishing drives
The polishing brushes are provided with polishing paste in freely programmable cycles. The polishing pressure can be regulated individually.
Sharpening principle
After pressing the start button, the knife changer removes the first knife from the magazine and transports it to the grinding position. An approach check detects the wear of the knife and starts the grinding program. After grinding, the machine first polishes the knife surface. Then the cutting tool is quickly and gently deburred. Meanwhile the knife changer restacks the magazine so that the following knife is ready for sharpening.
Belt filter coolant unit
The belt filter coolant unit prevents the cutting tools from overheating during the grinding process. If cooling is insufficient, the coolant monitor shuts the machine off. The coolant unit has a volume of 140 l. A filter fleece removes the grinding abrasion completely from the coolant circuit. The removed material is collected on the filter fleece and can be easily disposed of in an environmentally friendly way.
Suction unit
The integrated suction unit removes floating particles from the workroom. This enables visibility during the grinding process. Moreover, it protects the operator’s respiratory system.
