CK 300TH
Twin head PLC controlled grinding machine for circular knives
The CK 300 TH machine is equipped with a double grinding head, for the simultaneous grinding of the bevels on both sides of the circular knife, reducing the processing times of this type of knife, and for a burr-free finish on the cutting edge.
The machine can also grinds knives with a bevel on only one side of the knife.
Grinding with emulsion coolant or neat oil, for sharpening of carbon steel, stainless steel, HSS, solid carbide, knives.
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 operations of the processing.
The CK 300 TH machine is able to sharpen batches of knives of the same diameter.
The control system shows on the display the load current of the grinding wheel spindle motors, the time remaining at the end of the automatic cycle and the total time of the knife grinding process.
The CK 300 TH machine can be equipped with the teleservice program, if required.

Saving of 5000 working programs, and ability to export the saved working programs in a USB device, and to import working programs from a USB device
Working cycle for the grinding of bilateral or unilateral bevel knives, with free programming of total stock removal, roughing and finishing in-feeds, sparking out cycle, rotation speeds of the circular knife
Automatic cycle repetition, with automatic fast engagement, circular knife/ grinding wheel, and automatic starts of all motors, for grinding batches of unilateral bevel circular knives at a same diameter, bilateral bevel knives with the cutting edge centered with the knife body and at a same diameter if necessary, bottom knives at a same thickness
Rotation speed of the circular knife digitally programmable from 10 to 50 rpm for the removal cycle, and from 5 to 65 rpm for the sparking out cycle, and digitally controlled
User-defined calculation of the grinding slide stroke (total grinding removal), by the interactive graphic system, in the case of grinding of new bevels on a blank blade
Digital continuous control of grinding wheel spindle motors load current, with interactive ammeters, and selection of intervention if the maximum load current threshold is reached
All machine functions (start/stop motors, knife rotation speeds, alarms, etc.) are controlled by the PLC and the panel PC with touch screen display
Programming of a new working cycle during the automatic cycle
Indication of the time remaining to the end of the automatic cycle, and the total time of the automatic cycle
Automatic shutdown of all motors on completion of automatic cycle
