ROBOEdge Fully Automated Sharpening System

Creates the perfect sharp edge, every time!

Take the guesswork out of grinding, honing, and polishing all hand knives with the fully automated ROBOEdge knife sharpening system from PRIMEdge.

The ROBOEdge increases efficiency of processing operations while achieving a low total cost of ownership. The robotic sharpening system uses minimal parts and durable, long-lasting materials—and requires only one operator.

Capable of sharpening at least 65 knives an hour, operators can simultaneously refurbish other dull tools or conduct other tasks. The system also eliminates downtime with dual retractable drawers that allow one tray to be loaded while the other tray is being sharpened. In less than 50 seconds, each knife is hollow ground, honed, polished, and returned to the tray as the next knife is selected.

The ROBOEdge achieves accurate blade thinning, precision honing, and edge polishing in four simple steps:

Knife Recognition
An automated four-axis knife clamping system selects and holds the knife while the knife recognition system identifies the blade profile, thickness, and any bends which controls the sharpening process based on the information detected.

Hollow Grinding
Blades are hollow ground under a constant flow of coolant with proprietary synthetic cup stone wheels that ensure the proper grind in a single pass. The stones self-adjust when needed to maintain consistent spacing between stones for an accurate grind on both sides of the blade.

Honing/Edging
The blade is then edged and honed with PRIMEdge’s proprietary spiral stones, made to sharpen at angles from 22 to 45 degrees. Two spiral honing wheels automatically adjust and are timed to perfectly sharpen a cutting edge.

Polishing
Any burrs or grind striations are removed as both the hollow grind and cutting areas are polished at the same time guaranteeing a smooth cut and reducing resistance for all types of applications.
