Models
Chucks series MADV are self-centering. In the MADV version, jaw clamping is manual thanks to an operating key, 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.
- Can be used on every machine tool (lathe, milling machine, etc.).
- The big jaw stroke enables clamping of complex profiles that couldn’t be clamped well with an automatic chuck.
- Suited to realization of prototypes, samples and series, also of big pieces.
- A central screw supported by an axial sliding bearing transmits the clamping force to the jaws.
