The trapezoidal machine bed with high resistance to deformation and the unique, wide flat guides in all axes are primarily responsible for the highly rigid structure of the NZX 4000.With Y-axis and BMT turret (tool direct drive via servo motor), the turning centre achieves a milling performance with the top turret which can be compared to that of an SK 40 machining centre. For this purpose, the Y-axis provides a path of +/- 70 mm in the respective variant.
The main spindle with beltless gear drive already provides a performance of 37/30 kW (30 minutes/constant) as standard. The servo motor integrated into the turret disk decreases frictional heat, minimises vibrations, improves the efficiency and increases the milling performance with regard to speed, accuracy and surface quality.
By default, the NZX 4000 has a direct travel measuring system from Magnescale, which enables highest positioning and repeat accuracies in the two X-axes. Optionally, this solution is also available for the other axes.
The selection of several spindle boring diameters enables configuration of the NZX 4000 for the respective machining requirement. Depending on the task or workpiece requirements, the following spindle designs are available for the turning centre:
NZX 4000 A with ø145 mm spindle boring
NZX 4000 B with ø185 mm spindle boring
NZX 4000 C with ø285 mm spindle boring
A special feature is provided by the stable turret adaption for long boring bars up to 1000 mm. Various steady rests are also available as manual or NC-controlled version. In order to optimally use the large spindle bores, there are the additional so-called front and rear chucks, which are given priority particularly for pipe machining. For this reason, various necessary options, like workpiece limit stops, chucks or mandrels in the tailstock are available for supporting pipes.
