FANUC CNC Helps Turn Pipe Dream Into Reality

To produce an application-specific five-axis laser pipe cutter for its customer Metz Művek, a specialist in the manufacture of tape fastening systems, machine builder Unique Method sided with FANUC as its partner for automation solutions. Based on its experience, Unique Method only adopts the products of market-leading suppliers to ensure high quality and longevity. The company knew that choosing FANUC would mean reliability, productivity, spare parts support and comprehensive maintenance services. 

Adam Horvath, Managing Director of Unique Method, says: “The idea of developing a laser tube-cutting machine came up during discussions with representatives from Metz Művek, who presented their specific needs. Once we had matched these requirements with the possibilities we agreed to design and develop the machine, which we called the UMET UniTube 6000.” 

For the CNC system, a Windows-based display was a prime request of the customer as it would offer the potential to create custom screens. As a result of this and several other application demands, FANUC recommended its 31𝑖-LB CNC system, a control solution that is ideal for complex machines. Here, functionality such as contour stitching offers specific benefits. 

“The customer’s production utilises a special function provided by FANUC that stitches complex contours together, halving the cutting time and decreasing overall cycle times dramatically,” explains Horvath. “With this feature we managed to deliver cycle times equal to those provided by more expensive machines with much higher output capabilities.”  

Important functions of the UMET UniTube 6000, which provides rapid traverse speeds of up to 90 m/min and positioning accuracy of 0.05 mm, include surface tracking calibration and automatic bar feeding with length measurement, ensuring both minimal cut waste and safe operation. Moreover, accurate tracking of the workpiece arrives courtesy of the ‘3D gap control’ function. The FANUC 31𝑖-LB provides the level of control necessary for such an advanced machine.
