Automatic loader for 10 lame up to 1500 mm

Loading of blades on the automatic loader and the entering of program number and the blade Length.

Start-up cycle:

• The carriage positions itself at a default position with respect to the zero point of the machine;
• The loader places the blade on the magnetic chuck;
• Magnetic chuck magnetizes;
• Rotation of chuck to -35 °;
• Demagnetization of chuck followed by alignment the blade by pneumatic actuator;
• Actuator moves back and the chuck magnetizes;
• Rotation of chuck to the angle set in the desired program;
• Start grinding wheel, coolant pump and carriage movement;
• Fast approach of the grinding wheel to the blade followed by slow descent;
• When the grinding wheel touches the work-piece the automatic working cycle for roughing, finishing and spark-out begins;
• At the end of the automatic cycle the carriage stops at the right inversion point;
• The chuck rotates to zero degrees and demagnetizes;
• A blade washing cycles follows between the two inversions points;
• At the end the grinding wheel moves to the zero position point and the carriage moves to the cycle start point;
• Demagnetization of the chuck;
• Blade is unloaded;
• Rotation of chuck to -10 °;
• Washing and drying cycle along length of chuck;
• Afterwards the carriage moves to the working cycle starting point;
• The magnetic chuck returns to zero degrees;
• Begin a new working cycle.
