Euromac, a global specialist in the design and manufacture of punching and bending machines, is benefitting from NSK ball screws, linear guides and bearings in a new punching machine: the latest-generation XT with 1500 x 3000 mm capacity and new reinforced frame.
Euromac says that the XT sets the bar for innovation in the punching machine arena by being available in hydraulic, hybrid and electric variants. In each type, Euromac uses a different way of moving the main punching axis. In the electric version, for example, the technology holds its own patent. Here, acceleration of 90 m/s2 and stroke of sometimes less than 10 mm, means that impact load is a constant issue. With this thought in mind, there is a clear need for high-performance, robust and reliable linear motion products.
For the main punching axis on the electric Euromac XT, NSK therefore proposed its HTF SRD series ball screw with S1 ball spacers featuring grease-retaining attributes. These ball screws also make use of a special material named Tough Steel. Complementing the HTF SRD ball screw is the RA series linear guide with high acceleration capability.
HTF SRD ball screws take advantage of a novel end deflector recirculation system to achieve ultra-high speeds of up to 3 m/s, offering shorter cycle times and higher productivity. Importantly, this high-load ball screw ensures good rotational balance. NSK’s RA series of low-friction, high-load capacity roller guides provide high rigidity to deliver the traverse and repeat accuracy necessary in machine tools such as the Euromac XT.
After a year of comprehensive and successful testing, Euromac recently commenced volume production of its XT punching machines.
