Core Competence Every repaired and rebuilt spindle goes through various tests. When setting the encoder and sensor positions, speeds and rotation angles are checked. On the test stands developed by Diebold, the spindle is subjected to a test run lasting several hours in which the bearing temperature, concentricity, vibration level and pull-in force are measured several times. All data is summarized in a detailed test report and delivered to the customer together with the spindle. We guarantee: „Your spindle runs like new!“

On-site service If an on-site service is requested by customers, our service technicians will come to your factory. They will bring all the tools and parts that are needed for on-site repairs. In advance we clarify which spare parts are required so that there is no delay due to missing spare parts.

Quality & Advice Our well trained service staff repairs your spindles reliably, cost-effectively and, above all, quickly, so that your machines are ready for use again as quickly as possible. Only with professional spindle service your spindle will run like a new spindle. This is not guaranteed with every spindle “doctor”. If an apparently inexpensive repair does not achieve the desired service life of the spindle, it will cost you twice as much. Therefore: go to the specialist right away. Rely on uncompromising quality.

Repair process Incoming spindles that are usually covered with chips and full of oil or coolant are first disassembled in a separate room. The individual parts are then washed to “clinically clean” in the parts cleaning room. After the parts have been checked, the findings report is created. Defective parts are replaced, non-defective parts are reconditioned and reassembled. The ball bearings are measured and paired with the spindle and the rotating parts are prebalanced. All electrical components are tested and replaced if necessary. The spindle is then professionally rebuilt and goes through a several hour test run.

We offer the highest precision: Through our many years of experience as a spindle manufacturer, we offer the best quality. For more than 40 years we have been supplying spindles to the best-known machine manufacturers in Germany, Europe, Asia and the USA for the production, aerospace, mould making and automotive sectors.

Quality: The current capacity is more than 2,000 spindle shafts and components per month. The quality inspection of the parts takes place in the measuring room, quality class 2, which has a temperature constant of +/- 0.2 degrees per metre. Two Hexagon PMMC measuring machines of the highest accuracy level are used there.

500 new High Freuquency Spindles plus 500 spindle repairs go through our spindle department every year. The life cycle file of every spindle manufactured by Diebold or all third-party products that have ever come to us for repair, is kept in the spindle database. In this way, it is always possible to follow up what the report on the spindle was, which parts were installed and what was replaced. Access to the respective measurement protocols from the measurement room is also guaranteed from there. This is a very „lean“ and cost-saving process in which all information about the life cycle of a spindle is available in a matter of seconds.

Express repairs within 5 working days Speed in spindle repairs is crucial when your machine has broken down and no replacement spindle is available. We work in 2 shifts and can react very quickly to your emergency. Several employees are trained for each spindle model so that a repair can start immediately and there are no unnecessary waiting times.

Repairs with warranty A spindle repair includes replacement of the bearings, rework of the spindle taper, sensor checking, the test run, the documentation of the spindle repair and the test report. All parts are checked and, if necessary, renewed or reworked. The repair is done after approval from the customer. Diebold relies on the „one man - one spindle“ principle. This assembly principle means that a spindle is revised and checked by a single specialist. Each spindle receives an acceptance report which the respective engineer signs with his name and therefore guarantees for the professional testing and assembly.Extensive spare parts warehouse We stock spare parts for all spindles we manufacture and for many other brands and offer you an emergency service with repairs within 5 working days. Then you have your spindle back, in mint condition, with test run, documentation and 1 year guarantee!

We also offer on-site spindle service. For Diebold spindles, but also for other makes, for example after a crash, or if the urgency does not allow any downtime of the machine.
