For over 50 years, Gefran has specialized in the design and production of drives and control applications, such as sensors, installable on metal working machines. Gefran is one of the few players in the metal sector that can offer a complete package in terms of product lines and control technologies.
This section contains:
Discover the world of metal!
Find out how to control the compression roller in rolling mill
Find out how to achieve real-time position control of the blade for tie rods and metal profiles in the cutting machine by updating the position every 1 ms with a linearity error ≤ ± 0.02% FS and gaging repeatability of 0.01 mm .
Learn how to achieve 0.1 mm repeatability for high speed bending tools in spring making machines.
The best automation and control technologies for electric motors: these are the demands of the metal sector, one of the biggest energy consumers on the entire industrial scene.
Gefran provides this sector with engineering know-how, proposing drives to control AC and brushless motors as well as armature converters for DC motors.
Communication in industrial automation is now the real strategic tool for increasing a company’s productivity and efficiency because it provides an effective way to transmit quality data between different automation systems, to control machines and synchronization, monitor production lines, etc.
How was this achieved? And what will tomorrow’s trends be?
SAG uses roll forming machines with flying shear system. The production speed creates various design problems regarding mechanics and movement control. Gefran studied for SAG a highly dynamic control system.
