New standards in CNC tool grinding The ISOG 22 complies with all requirements of the EU Machinery Directive. The maximum tool length for automatic machining has grown significantly – to over 300 mm, whereas previously it was a maximum of 180 mm HIGHLIGHTS OF ISOG 22 Vertical system The special feature of the ISOG 22: It works according to the patented vertical system, and its tool spindle is perpendicular. This means: The tool is optimally accessible from all sides. Its repeatability in the μ range is also incomparable. The extremely high flexibility also benefits from this machine concept. Stable and compact A solid base is the stable cast mineral machine stand made of polymer concrete. With its large mass, it ensures good damping. Highest radius accuracy The very small distance from the grinding point to the pivot point of the C-axis guarantees the highest radius accuracy.

The ISOG 24 is breaking new ground here: For the first time, the airflow is directed downwards – physically convincing, as gravity goes in the same direction. Thanks to the controlled airflow, there is less fogging, which gives the operator a much better view of the grinding process. The supply air flows into the machine through a long opening at the top of the cabin. The airflows are smooth and straight, with low flow velocity. The airflow and the extraction are continuously monitored in real time and the real values are displayed in the machine data. These are compared with the minimum and maximum specifications of ISOG and displayed to the operator on the screen via a message as soon as the limit range has been reached. In addition, the exhaust air system has a fire protection flap as standard.

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
