Page 4: Safety
• only allow trained expert staff (specialised in metal) or CNC lathe oper- ® ators to work with the INOZet pendulum bridges. They have to be fa- miliar with the functioning of the pendulum bridges themselves as well as the functioning of the machine tool and its safety- and emergency systems and they need to know how to handle them reliably. -
Page 5: Technical Description
The pendulum bridges can be installed on the base jaws of any current chuck. ® the INOZet -clamping system must only be used with CAUTION clamping jaws of HWR Spanntechnik GmbH (see. chapter „6“ Technical Data). ® INOZ VERVIEW OF THE ENDULUM BRIDGES 2.2.1... - Page 6 Due to the doubling of the clamping points the clamping pressure is intro- duced into the workpiece more evenly and thus reduces the chance of de- formation. ® Adhere to the max. speed of the INOZet pendulum CAUTION bridges and of the chuck of the machine tool.

Page 7: Installation
LAMPING SYSTEM TRANSPORT WITH EYEBOLTS ® Depending on the size and weight of the INOZet - clamping system the pendulum bridges have to be installed on the chuck by using appropriate hoisting gear. -
Page 8: Installation On The Chuck
Step 2 Clean the reference area of the chuck of the machine tool and the reference area of the INOZet® pendulum bridges. There may not be any dirt or chippings in these areas. Make sure that all bore holes are clean and deburred. -
Page 9: Operation
Installation Step 4 For finding the ideal clamping position (3, Fig. 3-2) adhere to ®“ the chuck specific „instructions for INOZet (separate sheet in- cluded in the shipment). Usually the clamping position of the pendulum bridges will be found at half the travel of the base jaw. Deviations may be pos- sible due to the serration for example. -

Page 11: Maintenance
Maintenance AINTENANCE ® In order to guarantee failure-free operation the INOZet pendulum bridges and the machine tool have to undergo regular service and maintenance. Switch off the machine tool prior to the service and maintenance operation and secure the machine from restarting (see operating manual of the ma- chine tool). -
