Method of operation of the PZSE

The knife ring with dull knives is placed onto mounting cylinders which hydraulically transport it to the carrier disc inside the robot. The fully automatic process is started after clamping the knife ring to the carrier disc and closing the housing door.
Electronically controlled torque wrenches loosen the knife clamping bolts. Pushers move the dull knife forward against stops. Then the knife clamping bolts are re-tightened with the required torque. The knife ring moves forward into the next knife carrier position until all knives have been moved forward and the automatic sharpening program is started.

The Sharpening Process

The knives installed in the rotating knife ring are resharpened in a wet grinding process. The advancement of the grinding disc is electronically controlled with utmost precision. After all knives have been resharpened to the predetermined knife protrusion, the knife ring is cleaned inside the robot by means of a special cleaning system.
The resharpening and resetting is completed after approximately 45 minutes!
