HIGH SPEED HEADS FOR PLANETARY GRINDING OPERATIONS
High speed heads for planetary grinding operations. It is a range of accessories of high precision to grind holes ( from Ø 2 till to Ø 300 and more if they are used together with platform U-TRONIC D’ANDREA.), profiles, cams ecc with manual or automatic radial movement according to the models. Of simple project, they are self cooled and the hybrid ceramic bearings are greased by permanent grease without any kind of maintenance for a life of about 6.000 working hours. The grindstone’ s speed is controlled in changeable and progressive mode by an apposite frequency electric converter with microprocessor very compact which can be ruled directly by the CN of the machine tool where the spindles are working.
