Repairs of spindles spindles BHI

No matter whether you have a belt spindle, milling spindle or motor spindle, our highly qualified and motivated employees will bring it to the highest performance level – irrespective of manufacturer. We work systematically, efficiently and in a results-oriented way.

As a first step, our experienced employees determine the actual state of the spindle and document it. If the customer awards us the contract to rehaul or repair the spindle, it is time for our actual work to begin. All individual parts are cleaned carefully and defective parts are replaced. After this, all parts with rotary loads at high rpms are balanced according to DIN ISO 1940.

Assembly of the individual parts is carried out with adjustment to all relevant components such as bearing pre-load, longitudinal alignment, non-locating and locating bearings in our fully air-conditioned clean-room production.

Following this, electrical adjustment of all components is carried out. This includes setting the spindle sensors as well as adjusting the spindle to existing drives. Before the spindle can be used, we naturally subject it to a thorough quality inspection. We are also happy to carry out start up and the kinematics setting, as replacing a spindle often requires optimizing the pivoting cycles G7, cycle 19 and cycle 800 again. We measure deviations during pivoting and readjust the parameters.

If a spindle has a fault, our Spindle Service deals with the problem rapidly and efficiently. But why wait so long if problems can be eliminated in advance?

Our Spindle Diagnosis does not start with a fault but with a fully functional spindle. In our eyes, it is better to carry out diagnostics during running operation and to identify possible weak points. In our experience, 30 to 40 percent of all spindle defects arise due to insufficient or no maintenance.

With the Spindle Diagnosis you save money and do not require costly repairs or a replacement spindle. Naturally, our diagnostic work can be planned precisely in advance to avoid downtime on your machine tool.

Spindle Diagnosis means that we scrutinize the state of the anti-friction bearings and the geometry of your spindle, for example. In some cases, we can detect minimum deviations here which, over time, can become a serious issue. We also check the interface to the tools used as well as the clamping state of the spindle.

Our Spindle Service specializes in products from the manufacturers DMG, Franz Kessler, StepTec and GMN. If required, we would naturally also be pleased to assist with products from other manufacturers, too.

Through regular spindle diagnostics and spindle maintenance, you achieve
• an extended service life
• an increase in machine availability
• a rise in productivity and quality
• early recognition of spindle damage
• optimization of the machining process
