Unlike other Macro systems, in MacroJunior the chuck, not the electrode holder, has positioning tongues. A design which means that the electrode holders can be supplied at a very attractive price.The design with three reference points in the X-, Y- and Z-directions means that, despite any tolerance variations in the holder, the coupling repeats very accurately when it is locked with its screw connection.Tests and calculations done by independent researchers and institutes have established that MacroJunior, despite its small size, offers greater torsional rigidity than other significantly larger and costlier systems on the market.- More compact than any other system - Inexpensive electrode holders for good economy - Movable drawbar eliminates bending forcesFacts - Repetition accuracy: 0.002 mm - Recommended tightening torque, manual chucks: 4 Nm. - Permitted torque for 25 mm holder: 10 Nm - Permitted torque for 30 mm holder: 25 Nm - Maximum flushing pressure: 15 bar - Clamping force: 5 000 N
