MARTA SYSTEM is a CNC integrated resistance welding cell, manufactured by the italian Company GEM. This equipment provides unique technical specifications and for the first time joins togheter the advanced technologies of: - electric drive of all the welding heads, replacing the traditional pneumatic cylinders - Medium Frequency transformers. The inverter technology provides several advantages:
· remarkable improvement of the welding quality · extreme precision of the welding time and current · higher productivity joint leading to costs reduction.
The machine frame consists of two cartesian interpolated axes, which the BIG GUN is installed on. The main axis is made by an electro-welded frame, the second one is an aluminium structural section, very light and rigid, able to bear external stresses. The maximum working range 2300 x 1250 mm (larger working ranges available on Customers demand). The upper and lower welding heads are servo-controlled: they run up and down, so that it is possible to assemble workpieces having different work levels; furthermore, they may rotate at 360° around their own axis, in order to follow irregular shapes. On the side of the big Gun, a smaller scissor Gun is fitted with three axes so it can slide vertically (max. working range 200 mm) and rotate around its own axis; these arms are also servooperated. The 2 stations turntable, located in front of the gun, is of the electrical-mechanic cam type, ensuring high repeatability and reliability. A powerful robotic numerical control provides all the features for programming motion and integrates a constant current welding control, which allows to select the most suitable welding parameters. MARTA SYSTEM 10AX GUN is especially suitable for the assembling of wire and steel products, in 2 and 3 dimensions.
Gem S.r.l. , located near Turin, is a leading designer and manufacturer of components and machines for resistance welding.
The Company was born in 1986 making profit from two founders and two employees. The company began to operate primarily in Piemonte, now, in addition to covering the domestic market, it exports its solutions in most developed countries through a network of resellers or direct agents.
Today the group works with 35 employees and 4 external professionals, as well as various supplier partners. The design, development and production are carried out inside the Company or by controlled Companies. Actually GEM occupies an area of approximately 8,000 square meters ( of which 4,000 covered and 1,000 to be builded).
The Company has been operating since 2000 according to the norm UNI EN ISO 9001, constantly renewed and updated in order to better satisfy the Customers needs.
