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. Next to the horizontal grinding spindle a vertical tiltspindle can be mounted for grinding for example machines beds with under grip. 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.

The vertical grinding centres of the KEHREN Ri series have been the optimal combination of production performance and precision for years. These characteristics result from the more than 200 machines delivered worldwide, as well as the know-how and continuous further development at KEHREN. The KEHREN Ri series is characterised by the following features: — Universal application possibilities — Hard turning and milling — Wear-free linear drives in X- and C-axis — Hydrostatic bearings in the X- and C-axis — Concentricity and axial runout less than 1.5 µm — Graduation accuracy ± 1 angular second — Rotary table sizes up to >1,600 mm — Outstanding long-term accuracy and durability — Stable cast iron construction, best damping properties — Optional Y-axis — Optional double table version — Siemens Sinumeric One control — Remote diagnosis via mobile network or direct internet connection — User-defined access authorisations via RFID

Unsere vertikalen Schleifzentren der KEHREN Ri Baureihe bilden seit Jahren das optimale Bindeglied zwischen Produktionsleistung und Genauigkeit. Diese Eigenschaften resultieren, aus den Weltweit mehr als 200 ausgelieferten Maschinen, sowie dem Know how und der stetigen Weiterentwicklung im Hause KEHREN. Die KEHREN Ri Baureihe zeichnet sich besonders durch folgende Eigenschaften aus: —Komplettbearbeitung in einer Aufspannung —Hart Dreh- und Fräsbearbeitung —Verschleißfreie Direktantriebe in X- und C-Achse —Hydrostatische Lagerungen in der X- und C-Achse —Rund- und Planlauffehler unter 1,5 µm —Teilungsgenauigkeit ± 1 Winkelsekunde —Rundtischdurchmessern bis 1.600 mm —Überragende Dauergenauigkeit und Langlebigkeit —Stabile Gusskonstruktion, beste Dämpfungseigenschaften —Opt. Y-Achse im Schleifkopf —Opt. Doppeltischausführung —Siemens Sinumeric One Steuerung —Ferndiagnose via Mobilfunknetz oder direkter Internetleitung —Benutzerdefinierte Zugangsberechtigungen per RFID

The powerLine technology machines are specifically geared towards creep-feed grinding applications. Their mono-base design allows grinding widths (Z-axis) of up to 700 mm with a maximum spindle power of 105 kW. The compact, steel base designed powerLine model is equipped with linear guides in all three axes. All three axes (X, Y, Z) are driven by servo motors via ball screws (KGT). The standard version of the multiLine comes with high-precision linear scales for positioning of the vertical axis. The direct drive of the grinding spindle from 48 kW guarantees optimal torque transfer. Different measuring devices and CD (continuous dressing) units are examples of a wide variety of available options making it easy to customize the powerLine to your individual requirements.
