CK 500

Grinding machine with PLC control for circular knives and bottom knives

The CK 500 sharpener is very versatile, operation with very short setup times, for the grinding of carbon steel, stainless steel, HSS, solid carbide, knives, and bottom knives, Grinding with emulsion coolant or neat oil. The programming of the machine is extremely simple, by panel PC with touch screen display, and operator interface with guided menu, for entering the working parameters and the operation of the processing.
The CK 500 machine is able to grind batches of knives with unilateral bevel at the same diameter, bottom knives at the same thickness, knives with bilateral bevel and cutting edge centered with the knife body, even at the same diameter if necessary. The control system shows on the display the load current of the grinding wheel spindle motor, the time remaining at the end of the automatic cycle and the total time of the automatic cycle. The CK 500 machine can be equipped with the teleservice program, if required.
