Precision machining - Import export

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

The Macro-I is one of the largest grinding machines in the compact Macro series. With a dead weight of approx. 9,000kg, it offers efficient vibration damping, in combination with a grinding spindle with up to 37kW, it is the ideal machine for creepfeed grinding with high metal removal rates at constant, high precision. The Macro-I reaches its full potential where small to medium components, with high stock allowance, are to be produced in large series. It can be loaded manually from the front or via an automation interface. Two additional side doors provide ideal access to the interior, making it easier to reach workpieces and tools. The machine is perfectly designed and manufactured by us according to your requirements and commissioned at your site. With process support and individual software adaptations, you get complete first-hand service.
