Precision Surfacing Solutions

Precise and flexible processing of large workpieces

Our gantryLine models can process large, wide and heavy workpieces up to lengths of 5000 mm and widths up to 2000 mm with high precision. Special designs are also available to process wider and longer workpieces. This machine line with its variety of available features is suitable for surface grinding applications all the way through complex CNC manufacturing cells.

The sturdy gantry-style machine design features a modern vibration-free mechanical table drive, linear guideways in all axes, an over-sized spindle drive as well as ball screws and linear scales in vertical and cross axes. These features guarantee that today’s expectations in the precision machining of large surfaces are met for rough machining and high precision machining as well. The gantryLine achieves highest workpiece precision and surface quality.

Benefit Overview

  • Highest precision through gantry design
  • High thermal stability
  • Modular design
  • Modern table drive system
  • Multi-axes operation

Design Characteristics

Sturdy Gantry Design

  • Welded machine construction is tempered several times to achieve highest precision

Features

The machine system can be equipped with various options to meet application requirements and customer requests.

  • Table mounted or head mounted dressing devices
  • Various drive systems for grinding spindle
  • Electro-permanent magnet chucks
  • Coolant filtration system
  • Second sliding door (with second operator pendant) in rear of machine

Machine Concept

Three Controls Packages

  • xpressCube (surface grinding)
  • xpressCube Pro (simple profile grinding)
  • Sinumerik 840D (full CNC)

Modular Design

The modular design of our gantryLine enables the addition of a second universal support (e.g. for tilting grinding spindle).  The universal supports are controlled independently and can be positioned automatically. The programming of both supports allows the complete grinding of a workpiece in the same set-up. Special designs of this model can utilize up to four supports and can be equipped for other machining operations like boring, milling and turning. Different spindles and tools can be stored in an automatic tool changer. CNC indexers, CNC trunnion tables and measuring systems can be integrated as well.
