ROMI, the market leader in the Brazilian machinery and equipment industry, is renowned worldwide for its high-tech products, and demands from its suppliers high technical performance, quality and solutions with the best price-performance ratio. The motion plastics® specialist igus® has been a reliable partner for 15 years.
Currently, ROMI's portfolio is composed of various machine tools, such as turning centres, CNC machining centres and milling machines. The customers come from the most diverse areas such as aviation technology, agricultural machinery and automotive industry as well as consumer goods production.
ROMI has been relying on energy chain systems and chainflex® cables from igus® for almost all machine and plant lines, which have to withstand demanding movements, high accelerations and a high number of cycles, as well as exposure to shocks and friction on various surfaces.
With the new ROMI DCM 620-5X Hybrid Vertical Machining Centre, which was first presented in Brazil in 2017, the company aims to meet the constant demand of the Brazilian industry for solutions that increase productivity and efficiency. The plant combines machining operations and additive manufacturing (3D metal printing) and allows the addition of various materials in complex profiles.
A multi-axis triflex® R chain is used to enable head movement in different directions.
Two e-chains® from igus® are used in the machining and coating area of the plant. There they come into contact with oils and abrasive powders and are also exposed to high temperatures. The chains made of high-performance plastics always work reliably under these conditions and safely guide the chainflex® cables specifically designed for mobile applications.
In the ROMI GL240 gantry loader, igus® e-chain systems® also ensure reliable cable management. This application is an automation system for loading and unloading workpieces in ROMI machining centres. By using the gantry loader, loading and unloading time can be reduced by up to 80%, which means significantly increased production.
Due to the high travel speeds in combination with the limited installation space, the designers at ROMI needed an energy supply for this application that copes with these loads safely and reliably over a long period of time. "We are known around the world for cutting-edge technology that characterises all our products," says Douglas Pedro de Alcântara, product development manager at ROMI. As a result, e-chains® from the E2/000 series from igus® are now being used in the gantry loaders. They have a high strength and crossbars openable on both sides. This makes it easier to insert or replace the cables, which considerably simplifies and shortens installation or maintenance.
Thanks to ROMI's GL240 gantry loader, loading and unloading times at machining centres can be reduced by up to 80%.
The e-chains® of the E2/000 series have crossbars openable on both sides, which makes assembly much easier.
The Brazilian machine tool manufacturer ROMI uses igus® energy chains in the latest generation of its vertical machining centres, ROMI D, as well. "The new generation of this product line has integrated new technologies that are even better aligned to the specific needs of customers," explains Douglas Pedro de Alcântara of ROMI. "The precision as well as the robustness and durability of the machines, continue to be recognised differentials of the ROMI brand." "
The e-chains® from igus® are also used here for the movement of the X, Y and Z axes. In the X and Y axis of the systems, different energy chains of the E2 family guide cables and hoses. In addition, an E4.1L series chain is used on the Z axis. It combines strength and easy accessibility. The rounded edges of the crossbars and separators of the chain also ensure a long service life of hoses and cables. In addition, the crossbars can be easily opened, which significantly shortens the assembly time.
