Milling & turning spindle

 

 

Depending on the type of application, the adapter spindle can be designed with or without shaft clamps.  In this context, milling spindles without clamping function are limited to mere milling operations at the workpiece while turning operations are also possible with adapter spindles using shaft clamps. The major advantage of this additional function is mainly the fact that no additional tool holder is required for turning tools, which reduces machine costs.

Bearings

The bearing of the spindle is individually adjusted to the type of applications. For this purpose, we use spindle bearings that ensure the highest speeds thanks to elastic pre-stressing. For design and dimensioning of the bearing, we draw on our considerable experience in this field and our standardized bearing concepts.

Performance

In addition to lifetime grease lubrication, oil-air lubrication may also be implemented despite the complex installation of media pipes. This enables all typical power values, torque, and speeds of our milling spindles to be used with an adapter spindle.

Tool interface

The tool interfaces used correspond to the typical milling spindle interfaces, such as HSK or Capto. However, with lathe & milling spindles, mainly HSK-T (T= turning) interfaces with limited width tolerances in the area of the drivers, or Capto interfaces are used for support of the turning tools.

Clamping system

The system for clamping and/or arresting the spindle shaft also comprises radially acting clamping sleeves for infinitely variable clamping and/or Hirth serrations (defined segmentation) for very high holding torques of up to 1400 Nm.

Thanks to its low axial space requirements, the Hirth serration can be installed in front of the bearing on the operating side and thus guarantees the highest rigidity rates and permitted load ranges. In addition, in the design with turning operation, the spindle bearings are protected by this, which has a positive impact on the service life of the spindle bearings.
