With the model of the type 6245/4, we can offer a HSC spindle, which is easy and quick to install in your conventional milling machine. With the rear adapter, which is 63/80 available in popular formats SK / BT or HSK 40/50, the HSC spindle can be used in a jiffy. You benefit from the advantages of our spindles like highest concentricity, speeds up to 60,000 U / m and excellent stability

Of course, you get the right equipment (frequency, cooling compressor system, etc.) from our company. As a particularly convenient solution we would like to point to the system cabinet FXK3. Here, we have combined all components for operating the HSC spindle in a compact housing.
