Large bearings for wind turbines

The modular PV series enables the configuration of multi-technology machines and the complete machining of rotary components with diameters from 350 mm to 4,000 mm.

The series includes single-spindle machines, machines with two separate work areas, each with a tool carrier as well as pendulum slide machines to optimally balance non-productive and productive time.

The product range is designed to ensure that all applications such as turning, grinding, drilling or milling can be carried out on the machines. The individual models can also be fitted with a Y-axis to enable PITTLER SKIVING.

Find out just how extraordinary flexible the series and its equipment options is.

The machine type with horizontally arranged spindles is a box frame welded construction made of steel with two coaxial, opposite grinding spindles. The main drives of these directly driven, liquid-cooled motor spindles each have an output of 24 kW to 100 kW.

Transporting the workpieces is possible with the widest variety of designs. Depending on its geometry, a linear feed can also be used. With this type of setup, the workpieces are fed and guided to the grinding tools using guide rails. A proprietary Diskus IONIC measurement control ensures a 100% measurement at the discharge.

The measurement results of this post-process measurement control are transmitted to the machine control, a SIEMENS 840D sl, and used for automatic correction, if necessary.
