Machine bed

  • Heavy ribbing of the 45° inclined bed with wide box ways ensures excellent vibration damping, especially during continuous cutting operations.
  • This design is very spacious, featuring a large work space for tools and improved chip removal
  • A wide support saddle with maximum guide length will result in significantly more stability and much less vibration
  • The preloaded ball screws connect to powerful drives via a zero-loss transmission clutch, and extensive bilateral bearings ensure high axial and radial rigidity and minimize deviations caused by heating and preloading of spindle

Main spindle and headstock

  • Excellent rigidity and minimum influence of fluctuating operating temperatures are possible due to an innovative and massive spindle head design
  • Thermal stability is achieved by strictly symmetrical builds and cooling structures that ensure consistent cooling air circulation around the entire spindle
  • The main spindle is designed for demanding loads and lasting accuracy, it includes precision dual cylinder roller bearings on both sides, plus additional angular ball bearings on both sides of the front bearings

Tailstock

  • The rigid tailstock for shaft machining provides additional flexibility in production operations
  • The design with 2 additional box ways ensures collision-free tailstock movements. Extra long guideways, superior rigidity and precision of guides result in excellent vibration damping even during heavy machining operations
  • Automatic tailstock is available as an option.

Equipment

  • Servo-turret for quick and precise tool changes
  • Solid structure and powerful clamping virtually eliminate vibrations completely resulting in a significantly longer tool life.
  • High tool changing dynamics are achieved via high-torque servo motor
  • L models offer an additional center width for even more capacity
  • Perfectly organized layout and well-designed details ensure maximum operator comfort and a comfortable work environment
  • Optionally, a hydraulically self-centering rest from SMW can be used, and the included tailstock allows machining of long workpieces

Fanuc 0i TF control

  • Easy programming and operation, short learning curve
  • User-friendly graphics display for visual verification of parts programs
  • Use of existing programs without reprogramming requirements
  • High-speed machining and standard nano-interpolation
  • Fixed cycles and custom macro B for simplified parts programming
  • State-of-the-Art functionality, like jerk limitation, nano smoothing, and Al Contour Control ll - compatibile with previous version series 0 and series 0i models A, B, C and D
  • Series 0i Model F are the successor models of the Series 0 and Series 0i, which are the most popular CNC controls worldwide with over 700,000 installations. STAHLWERK also features the latest FANUC drive technology.
  • With up to 4 controlled axes, the CNC Series 0i provides the best controls to meet the high demands of STAHLWERK Premium Line machine tools.

Alternatively available with a Siemens Sinumerik 828D.

  • Compact, robust, maintenance-free control panel-based CNC
  • comfortable program and parameter input via QWERTY keyboard
  • 100 adjustable zero offsets
  • Synchronous actions, and quick output of help functions
  • Maximum machining precision
