ST-20 CNC Swiss-type Automatic Lathe

ST-20 CNC Swiss-type Automatic Lathe

Machining with the highest specifications and functions that deliver high productivity and profitability

  • Simultaneous machining capability such as turning and milling by opposing twin turret tool posts drastically reduces machining time
  • Main and sub spindles are both capable of the same level of machining which enables complex parts to be machined with incredibly short cycle times and to a high standard of quality
  • Equipped with 3 turrets for ultra-high speed flexible machining
  • Elaborate array of turret posts allow for a wide range of tooling configurations for seamless multi-processing
