High-speed coil winding requires the use of a tensioner between the feed coil and the receiving coil (end product). Fine control and the trend towards using larger-diameter wires to meet the high demand for electrical equipment such as transformers means that tension control solutions are required which offer high torque density as well as easy torque control. ALTIC, inventor of the modern tensioner and a benchmark for the sector, has selected EMP electromagnetic brakes from MEROBEL for its entire electrical and electronic range.

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.
