Swiss Type CNC Automatic Lathe


S20 features a compact rigid machine structure with a slanted dovetail way ensuring accurate, smooth and reliable performance with exceptional dimensional accuracy. The high rigidity and durability results in extended cutting tool life. The Swiss-type sliding head design in combination with an array of customizable cutting tool modules can incorporate up to 30 tools. This machine is especially suited for the machining of high precision complex parts for the medical, aerospace, watch and automotive industries all at extremely fast cycle times.

Machine Features

  • Slanted dovetail way

  • Precision linear guideways & rigid ballscrews on all axes

  • Uniquely designed coolant channels for optimal thermal dissipation

  • +/-40mm of travel on Y2 backworking module & equipped with 8 driven tools

  • Main spindle 10,000rpm, 2.2/3.7kW
    Sub-spindle 8,000rpm, 1.5/2.2kW


Simultaneous Machining,
Double Y-axis for Complex Machining

For complex precision parts this machine has simultaneous machining capability on the main and sub-spindles. There is also +/-40 mm of travel on the Y2 backworking module which is equipped with 8 driven tools. The S20 can accommodate a variety of tools for overlapping and simultaneous operations. Both the main and sub-spindle, feature full C-axis capabilities and can perform fast and accurate backside machining. This Swiss-style design with or without guide bushings delivers versatility, rigidity, and high performance, perfect for short runs of complex parts made complete in a single set-up.
