Plant general view before modernization.
Definition of a project
The technology of the plant was obsolete and the spare parts are not available. The target was the complete modernization of the total plant for hardening of drive shafts in shortest downtimes.
Mechanical modernization
The equipment was deconstructed in all single parts and all wear parts of the plant (journals, connectors, sealing gaskets, gear rings and guiding shafts) were replaced. By using new cylinders, valves and supply units the pneumatic and hydraulic systems were modernized all around. A higher plant dynamic was achieved by using servo drives.
High voltage and converter
The high voltage transformer as well as the converter plant of the hardening processor in transistor technology were replaced. The existing supply racks were revised, the water cooling system was modernized.
Electrical modernization
It becomes necessary to replace the electrical plant installation including switchboard cabinet, operating, sensor technology and cabling completely. All safety functions were realized by the use of safety control and corresponding drive controllers. Via industrial PC as well as and mobile panels operating was realized.
Process optimization and Visualization
Via visualization tailored to the plant an operator guided control as well as an optimal process supervision of all plant conditions were realized.
CE and documentation
Based on the new conformity declaration of the plant it becomes necessary to prepare an extensive documentation including risk evaluation according to appendix VII of the EC machinery directive.

Our philosophy
Only if our systems are integrated at the customer completely they develop their entire performance potential. Therefore it is important for us that our customers are integrated in the process from the very first day of the project carry out. Communication is about it the most important connecting part between us and our customers.
Customer targets
- Maximum production efficiency and quality
- Stable industrial processes
- Well trained personal
- Low service costs
- Most favourable conditions
