Ergo 850 G

Ideal for turning and grinding parts sized up to 850mm, the Ergo 850 G features a turret flanged at the bedframe, enabling shear stress to be subdivided evenly during heavy machining operations. The machine can be developed for various power feeds, as required, giving it unbeatable production autonomy and flexibility.

Advantages:

  • Turning and grinding in a single set-up on the one machine, enabling major capex savings.
  • Superior quality and high output levels, thanks to machining in a single set-up.
  • Extreme precision thanks to the thermal stability and vibration absorption of the bedframe.
  • The quality standards delivered in turning operations means grinding is necessary only for superior quality finishes, where micrometric precision is required.
  • Minimal wear of the grinding wheel reduces dressing frequency and significantly reduces cycle time.
  • Diamond wheels can be dressed with a stationary dresser, roll dresser, or high-speed crush roll.
  • The design of the work area and the pick-up spindle ensures that swarf and filings fall away freely.
  • Minimal loading/unloading times thanks to extremely short strokes.
  • Linear guides and control guards shield the work area to prevent swarf and filings interfering with loading or causing wear and tear to machine components.
