Manual jaw box SMW-AUTOBLOK standard mounting dimensions
Manual jaw box with semi-finished body
Application/customer benefits • JBX: Standard mounting dimensions for SMW-AUTOBLOK chucks
• JBX-2G: Semifinished body and radial reference key to be adapted by customer • Manual radial setting and clamping of large components on large plates or chuck • Added to chucks there is more gripping force to apply a higher torque on the workpiece • Added to chucks there are more contact points with the workpiece to better distribute the gripping force thus reducing distortion • Very powerful and accurate clamping allowed by strong design • Suitable for vertical machines thanks to the fully protected body • Use of standard hard or soft jaw on top of the master jaw or special frontal jaws on the front side of the master jaw • TONGUE & GROOVE master jaws (type “American Standard”) Technical features • Manual gripping force applied by a strong and protected screw on a strong and rigid master jaw • Manual and fine setting of master jaws for workpiece centering

Maximum protection
Flexibility of use
Master jaw protected on each side by steel profiles. Maximum protection from the penetration of chips, swarf, rubber and coolant allows less maintenance, working in bad environments and for a longer operative life.
The jaw box can carry both standard or special, hard or soft jaws mounted on the upper side of the master jaw or special jaws mounted on the front side of the master jaw. The jaws on the front side allow optimal clamping in the same axis of the master jaws thus reducing deformation of the jaw and the jaw box. This allows a more rigid and accurate clamping. Also the frontal jaw option increases the flexibility allowing the customer to clamp the component in a very low area where it would be impossible to clamp with traditional jaws mounted on the upper side of the master jaw.
