Edge Milling

Tecoi is a Spanish Company that design , manufacturers metal processing machines for various applications from Cutting to Plate machining to Edge Preparation for Welding.  

The Edge Milling machines from Tecoi, the model TRF is a flagship model from Tecoi, offering exclusive CBM technology.. Featuring a robust and efficient design, this exclusive TECOI model allows high-speed production of quality bevels even in large thicknesses. 

Despite its robust and innovative design, the truly differential feature of the TRF range is its unique milling system, the Cold Bevel Milling (CBM) technology. This TECOI-exclusive development allows both edges of the plate to be prepared for high-responsibility welding processes completely by mechanical means, without thermal input nor chemical alterations. The CBM system manages to remove the surface layers of the plate by applying a milling tool specifically designed with the shape of the bevel to be achieved and connected to a high-power motorized head.  

In this sense, one of the main advantages of CBM technology is that, unlike traditional edge preparation systems like oxyfuel cutting, its use, as based on mechanical chip removal, does not generate heat or add temperature to the processed material, making subsequent welding processes easier and resulting in safer joints and higher quality assemblies 

The TRF models find application in Oil and gas industries, Ship building , Wind Power, tanks and Pressure vessel fabrication.  

The TRF machines consists of a self-supporting TRF gantry features a rigid electro-welded structure that moves horizontally on a guide system along the X-axis. Able to incorporate one or two machining heads, it is based on two feet at both its ends that house the motor system, and has been specifically strengthened to neutralize any vibration during the milling process. The TRF performs an innovative double-channel structure that allows the incorporation of milling heads at both ends of the gantry to simultaneously process the two sides of the plate. This design has been precisely conceived so that these simultaneous operations do not result in any loss of quality or efficiency in either of the two bevels. 

Equipped with high power motors able to generate the optimum amount of revolutions required for a fast, clean milling, these machining heads also incorporate state-of-the-art positioning technologies that allow the distance between them in the Y-axis to be modified in real time according to the width of the processed plate. Exclusively manufactured for TECOI, these tools feature several different angles & shapes to make I, K, V, X and J bevels in one single pass. TECOI also offers the possibility of custom their design, tailoring it to each project requirements. The flexibility in the design of TRF tools also makes it suitable for narrow gap welding preparation. 

To carry out jobs that require to produce different shapes and bevels, TRF machines can incorporate an automatic tool magazine per machining head at the ends of the gantry. Able to automatically perform quick and autonomous changes between tools, these magazines can also feature up to 5 different positions.  A manual version is available as well. 

Instead of the reinforced cutting tables equipped in TECOI thermal cutting machines, TRF features a high-resistance magnetic bench. This element consists of a magnet grouping system of 16 double units for each 12 m (39 ft.) of the plate to be processed that ensures its maximum stability and avoids vibrations during the milling process. 

TRF machines are equipped with one or two control cabins, depending on the number of heads they feature. These cabins host the numerical control, specifically designed by worldwide leading manufacturer FANUC for this range of machines. Similar to TECOI cutting machines, these CNCs ensure a fast execution of all processing commands. 

The TECOI TRF offers an operational of 4200 mm in width to a max length of 45,000 mm , with a max operating thickness of 200 mm, with spindle motor power from 30 to 100 KW depending on the application.  

The model TRF 4000 in common applications, can bevel 70 mm thickness in one pass and 100 mm in 2 passes. Beveling shapes can be K, Y and V shapes.  

The model TRF 5000 in common applications, can bevel 120 mm thickness in one pass and 200 mm in multiple passes. Beveling shapes can be K, Y, J and V shapes.  

TECOI  also have the TRF PowerDrive, the high-end version of its prestigious TRF. Designed to offer an unmatched machining capacity and the best efficiency ratios on the market, this new model manages to feature 115 kW milling power on each of its heads, which means up to 300 mm thickness milled at maximum speed in even less time.  

Although the new TRF PowerDrive keeps the differential features of the TRF range, such as its double-channel structure for simultaneous milling of both sides of the plate, it adds a renewed system of dynamic dumpers that enhances its significant power jump by neutralizing vibrations and providing an excellent dimensional stability.
