Machines of series PFS are specially designed for machining of steel blocks and components. The very rigid design and high power rates ensure that an outstanding machining performance can be achieved.

Design of columns and cross rail are based on the high forces during steel machining. Therefore we provided an enhanced and rigid design. For optimized damping both columns are provided in a stable ribbed design.

The machine table is guided hydrostatically on two guide ways. Thus a high damping effect during machining is guaranteed. Table drive is performed by an electronically trussed rack and pinion.

To reach a high level of automation the machines can be, based on customer requirements, equipped with an automatic tool changer and automatic head changing unit. An integration of chip conveyor, coolant filtration unit and table clamping system is part of our standard service program.

Machining of aluminum parts requires different machine performance than machining of steel. Therefore we have developed the machines of series PFA. They are based on our modular system and can be modified economically and easy depending on specific machining requirements.

The machine consists of the following main sub-assemblies:
 fixed columns and vertically adjustable or fixed cross rail
 shuttle table with two separate clamping surfaces on the machine table
 head stock with integrated vertical slide, main spindle drive and work spindle drive

As a standard also this series is provided with columns in steel-welding design. A special ripped design guarantees very good damping performance. The shuttle table consists of two parts, a cast iron bed and a cast iron clamping plate. It is provided with a high performance feed drive.

The modular design of the machine simplifies service and maintenance of the machine. Thus the non-productive time is minimized. Sevice work can be performed almost without loss in production.

The gantry type milling machine PFGA X-32 for example, was developed for the high-speed aluminum machining as it is important for the aviation and astronautics industries. Machines of this series can be provided with up to 8 separate headstocks. Each spindle is provided with a power of 32 kW in continuous operation. Thus 8 work pieces can be machined simultaneously. Two separate clamping surfaces on the machine table guarantee clamping of the work piece during primary processing time whereby the non-productive times are reduced.

The machine is completed with a high dynamic tool changer, either traveling with the portal or installed fixed at one end of the table. In total the machine is provided with 27 NC-axes.
