Automatic Sharpening and Polishing Machine B 600

The B 600 sharpens, polishes and deburrs cutter knives up to a size of 1000 l fully automatically. The knife changer picks up the knife from the magazine and moves it to the grinding position. The sharpening program is started. After the grinding process is finished, the knife is returned to the magazine and the next knife is picked up. The machine processes up to 16 cutter knives in unmanned operation.

The output is approx. 80 cutter knives (500-750 l) per 8-hour shift with 1-2 hours of personnel deployment. With each regrinding the complete blade profile is processed. The average process time per knife runs from 3 to 5 minutes, depending on the blade size. There is very little material removal from the knife. A 500 l cutter knife can be reground up to 40 times.

Sickle-shaped knives as well as linear-shaped knives can be ground. The maximum knife size is 600 x 400 mm (23.6 in x 15.7 in), that equals a cutter knife of around 1000 l.

The B 600 is very easy to control. The operator determines the most important functions, such as the number of the grinding and polishing cycles and the crowning of the knife, via touch panel. This means that with every re-sharpening, the blade is given a cutting edge, tailored exactly to the product.

The created grinding programs are stored in the data memory of the machine. The number of grinding programs is unlimited. Updates and new ­programs are loaded onto the B 600 online.

The advantages at a glance

Knife holding fixture SP 114

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

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

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

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

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.
