Models
MADT chucks series are self-centering. Jaw clamping is automatic through a draw rod and a rear cylinder, with a manual indexing system. Standard with 4×90° + 1×45° indexing; special positions (8×45°, 6×60°) available on request.
Advantages
- Self-centering clamping.
- Big clamping capacity.
- Versions with long jaws for workpieces that need a big radius of revolution.
- Quick and easy installation to the machine — only the connection to the hydraulic cylinder on the lathe is required.
- Suited to manufacturing different pieces and small series.
- Handles workpieces with big radius of revolution and flanges with big diameter.
- Can be applied in the same machine with a conventional 3-jaw power chuck thanks to quick retooling, increasing flexibility and productivity.
- Indexing device allows a quick change between multiple working axes.
- Good tool accessibility thanks to the chuck shape.
