Optional mechanical pressure monitor with inductive
proximity switch
If the chuck is ordered with the optional mechanical pressure
monitoring (SCHUNK ID no. 0818205), this option is already
integrated in the chuck.
The monitoring function has been set to the working pressure of 6
bar.
If the working pressure has to be changed, refer to the
chapter “Mounting of the optional mechanical pressure
monitoring system”
Pressure monitoring is possible only if the chuck is in a specified
position within the lathe. The pressure can be monitored only for
O.D. clamping setups.
After attaching the chuck and the distributor ring the mechanical
pressure monitoring system should be put into operation.
Insert the switch cam (93) into the rod (99) and tighten the set
screw (107).
Pressurize the chuck to the working pressure (6 bar) so that the
jaws move radially inward. The switch cam moves to the right.
Adjust the inductive proximity switch mounted on the machine so
that it is triggered by a 1 mm leftward movement of the switch
cam
–
this corresponds to a pressure loss of 1 bar (see Fig. 7
“Mechanical monitoring”). Mechanical pressure monitoring is
possible only for O.D. clamping.
DANGER
Potential danger of death for operating personnel due to loss of
workpiece and objects flying off.
If the inductive proximity switch responds there is a loss of
clamping force in the chuck.
•
If the inductive proximity switch responds, do not operate
the machine!
