With the new GGTronic, Italian OEM GIANA decided to position itself on the higher level of machine-tools technology. “It is the only way to survive” explains Giulio Maria Giana, the company manager and technical director. As this milling & turning equipment in one set solution for big mechanical parts, very high rigidity becomes obviously a crucial design feature. Positioning has also to be very precise, reaching values as low as ±0.01mm, with a repeated accuracy of ±0.005 mm. To achieve these performances, GIUSEPPE GIANA went one step ahead by implemented REDEX-ANDANTEX’s TwinDRIVE on the machine, the original rack and pinion drive solution.

This planetary reduction gear for rack and pinion applications offers exceptional rigidity characteristics, in particular through the one-piece output pinion technology invented by REDEX. It provides unrivalled radial rigidity (accounting for up to 60% of overall rigidity).

Could a company specialised in mechanical transmission components be happy with the emergence of low cost countries? This is the case for REDEX-ANDANTEX, which has been able to build successfully on a family shareholder base for several generations, by putting innovation and quality to the fore, and by opening up to international markets at a very early stage in its history; all these key factors of success are usually attributed to the industrial companies on the German side of the Rhine.
