FLEX-BALL is a switchable permanent magnet for flexible clamping of magnetic workpieces and is suitable for use on milling machines, grinders and particularly to laser welding systems. In any rotating and swiveling ball receiving a switchable permanent magnet is mounted, which serves for clamping of the workpiece. This ball receiving is stored in a switchable permanent magnet shell. This patented arrangement allows hitherto unrealizable degrees of freedom.  So angles >90° can also be adjusted and securely fixed. Owing to limited angle workpiece weights can be spanned up to 100kg. For clamping of the non-magnetic workpieces, a vice or a jaw chuck also can be clamped on the magnetic chuck.
