11.3. Lathe output utilization (Fig.11.1)
In Fig. 11.1 there are mutual relations between:
• spindle revolutons per minute and power output transmitted by work spindle.
• cutting speed for diameter range 50 to 1050 mm and cutting speed.
• power output of electric motor and spindle speed.
• max. spindle torque and spindle revolutions per minute.
• accessible chip cross section in full lathe utilization and spindle
revolutions per minute on turned workpiece.(Assumption:max. cutting
force 50000 N ).
• max. mass of chips in kg per hour.
The departure of carriage from emergency switch and emergency stop.
The position of carriage when is in the extreme position (safety switch is on the emergency stop - contacts disclosed) on the
screen the signal is displayed:
