Modernization & Retrofitting

Retrofit and service

Especially in the segment of XXL machines the area of retrofit and service is a very important field. When buying a new XXL machine, one has to consider the costs for the machine as well as those for the periphery (foundation, media connections, etc.) By having the machine retrofitted, the customer saves this effort and receives a nearly-new machine at a lower cost. Furthermore, this machine suits the existing layout and fulfills all current technical requirements.

Our worldwide retrofit is independent of manufacturer and machining processes and involves overhauling of machine tools and machine tool components. To facilitate this, not only the required Schiess assembly team but also the capacities of Purchasing, Manufacturing and Quality Management, Electrical Commissioning and Documentation are available. This means that these projects also benefit from the same quality and service that you get when buying a new machine.

We offer you a worldwide service for the machine tool, provided by our service teams. This is not only independent of the manufacturer but also independent of machine type and involves everything including setting up, alignment, commissioning, troubleshooting, test machining and customer specific requests.The service by Schiess is independent of the manufacturer and the machining processes and provides worldwide support for machine tools and machine tool components.In addition to service, we also offer preventive measures to guard against machine failures/downtimes e.g. in the form of service/maintenance contracts. These are negotiated and adjusted on a customer-specific basis.

We offer:

    • General overhauls of machines of various manufacturers
    • Retrofitting of conventional machine tools with CNC-control incl. all necessary mechanical modernization work
    • Partial overhauls
    • Relocation of machines
    • Geometrical inspection of machines and adjustment, if required
    • Provision and delivery of spare parts
