Lathe power chuck
BL-2 E Mario Pinto

These power chucks were developed for the clamping
of bearing rings, but have excelled on turning operations
(roughing out with external or internal clamping;
semi finishing and finishing with internal clamping)
and grinding operations, where a very good roundness
is required.
This 2+2+2 balanced jaws system ensures minimum
workpiece deformation.
Technical features:
- Preparation for double central passage for centralized
lubrification (compulsory) and air (blast cleaning or
workpiece control). 3 rd central passage upon request.
- Centrifugal force compensation
- Internal mechanism offering unique features and
performance (protected by European patent no.
