The ZPS Swiss series covers the range from 3- to 32-mm bar diameter and is designed for continuous or series production of precision turned parts. The Swiss-type turning centers provide outstanding accuracy and quality surface finish conditions for precision parts, the company says. The machines are equipped with the GE Fanuc 160i control systems and drives that are capable of handling as many as 12 controlled axes.

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

Swiss Plus operates with Windows and offers user-friendly programming specially adapted for simultaneous operations. Each machining operation is individually programmed in ISO code with graphic interface and tool library. Swiss Plus generates the part program by taking into consideration the machine kinematics and machine requirements. The Swiss Plus, integrated in the Fanuc 18i controls, or programmed off line, ensures the full benefit from ZPS Swiss’ performance.

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

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 (more than 250 mm) through the subspindle.

Three live spindles may be fitted on the rear tool rack for cross drilling and tapping as well as milling with the Y axis. Multiple live spindles also enable high-speed drilling, polygon
turning or thread and slot milling. Two axial and three transversal live spindles may be fitted on the rear machining unit in order to work via the subspindle. Out of the 24 tools available, at least 16 can be driven.

A range of optional equipment, including NC drive of the pick-up spindle, barstock feeding and clamping, attachments for high-speed drilling, reaming, tapping and broaching, and multi-spindle drilling heads on the frontal slides.
