High speed air precision chuck APC-H

For the usage of a precision air chuck at higher spindle speeds, the chuck can be
modified. A centrifugal force compensation ring will be mounted on the OD of the chuck, to equalize centrifugal force at higher spindle speeds. With this chuck version it is possible, to realize a speed up to 6,000 r.p.m. Standard size, 150 mm
