The ZPS Swiss series from ZPS America covers the range from 11-mm to 32-mm bar diameter. The European-built Swiss-type machine is designed for continuous or series production of precision turned parts. Solid base casting ensures maximum rigidity and stability, the company says. The machines are equipped with the GE Fanuc control systems and drives that are capable of handling as many as 12 controlled axes, including main and counterspindle.

The specially developed programming software, Swing Plus, simplifies the programming so the programmer takes into consideration only the X, Y and Z axes during programming just as on typical two-axis CNC lathes.

The software operates with Windows and offers user-friendly programming specially adapted for simultaneous operations. Each machining operation is individually programmed in ISO code with a graphic interface and tool library. The software generates the part program by taking into consideration the machine kinematics and machine requirements.

It's possible to machine a part with as many as four tools cutting simultaneously. The sliding headstock provides as many as 250-mm stroke that enables part machining in succession at one collet clamping as well as the machining of long parts with small diameters.

There are 23 tool stations and 14 stations can be driven, so the machine can finish the most complex parts that are otherwise machined, in several operations. The use of two identical spindles increases machining capacity in rear slide operations and enables evacuation of long parts through the subspindle.
