Control system makes CNC milling easy to use
Thanks to a powerful, user-friendly two-axis control system and precision glass linear encoders, a miller is able to play a key role in EDM electrode production.
For milling operations, the working range is 13m in the X-axis, 4.5m in the Y-axis, and 2m in the Z-axis.
The maximum turning diameter is 5m.
The cableway manufacturer intends to take delivery of the machining centre in Autumn 2008 at their manufacturing facilities in Wolfurt, Austria.

Competance in manual machining is essential
Joanne Naylor believes that it is very important for trainee production engineers and machine operators to be competent manual machinists before they are allowed anywhere near a CNC machine tool.
Doppelmayr was seeking a multifunctional machining centre essentially to carry out precision machining of large components for cableways, such as the large cable pulleys and cable supports.
The company expects to machine even bigger components, so the machining centre specification also included a requirement to mill parts 12m long and 2m high.
Also the machining centre had to be able to turn a diameter of 5m.
In its specification, Doppelmayr stressed the value of a good ratio between machine working area and the amount of floorspace required.
The production engineers anticipated a machining accuracy with an average spread of maximum 15 micron over the entire X-axis, 7 micron on the Y-axis, 4 micron on the Z-axis, and 4 arsec on the A-, B- and C-axis.
Following a visit to DST's Droop+Rein product plant in Bielefeld, Germany, and after holding technical consultations with other users, Doppelmayr's production manager, Karl-Heinz Zuendel, and his colleagues were convinced of the high availability rate provided by the FOGS series of machining centres.
Zuendel also placed importance on a comprehensive customer service, he said: "We believe that the total cost of ownership is more crucial than the actual cost of the investment.
This is why we place value on high quality, a comprehensive diagnostic system, and a qualified teleservice".
The machine is sub-divided into two working areas as standard.
However the partition wall is removable so that large pieces can be machined on the floor plate.
The basic design of the machine is the Droop+Rein upper gantry design FOGS D40C milling centre.
The Z-Ram unit accepts fork type milling heads, angular or face milling heads as required.
Its driving power is 40kW, torque is 1,800Nm and spindle speeds range from 20 to 6,000 rev/min.
When blocked, i e, when the spindle is without load, the milling head can also be used for turning operation.
The machining cente incorporates a turning table manufactured by the Doerries product range based in Moenchengladbach, Germany.
In this way the client is benefiting from machine tool synergies and from the expertise provided by both divisions.
The machining centre contains an automatic 120 pockets toolchanger.
The Siemens Sinumerik 840D control system handles all the CNC functions.
"By investing in this expansion we are very much looking forward to being able to offer our customers even greater benefits," said Zuendel.
