Various Wittmann machine hoppers can be retrofitted with the pivoting device, using a clamping ring
and an adapter.
The balloon style biaxial failure has had some success when special molded sheets of elastomer are constructed wherein a thick clamping ring
is molded into the elastomer membrane to allow a strain transition at the gripping region.
A clamping ring
protects the sealing around the cable housing and delivers output forces of the value demanded by DIN 0627.
The angle design of the clamping ring
and cylinder shoulder increases the spring force 300 percent.
EACH KIT COMES WITH A CLAMPING RING
, ANTISEIZE COMPOUND FOR THE STUD NUTS, TWO REPLACEMENT STUDS/RETAINERS AND INSTALLATION INSTRUCTIONS.
For finish milling applications, tightening the chuck's clamping ring
until the black area on the toolholder body is no longer visible will achieve high gripping torque and minimum runout.
