Spindle regeneration

Regeneration of spindles and electric spindles, on the other hand, involves the replacement of mechanical components of CNC machines that have failed. Restoring the efficiency of cutting machine components is an effective way to improve the parameters of a milling machine, grinder or lathe.

Restoring the original parts of the numerically controlled equipment will save time and keep the initial indicators. The repair of the equipment is preceded by a mechanical audit, which will also show whether the precision bearing needs to be replaced.

We will also restore worn windings, repair clamps with defects, renovate sensory, pneumatic systems and hydraulic or cooling systems. In this case, service and repair include on replacing the seals of individual components.

However, the main and the most important activity improving the equipment will be balancing. First, we test the static restoration of forces in the rotating element, then proceed to perform the same action already in dynamic conditions.

Repair of electric spindles

Equipment used for cutting and forming various types of metal, wooden and artificial materials is an important element of the equipment of every machine park. The smooth and trouble-free operation of CNC equipment speeds up production, while the failure of one of the components can slow down the process and generate serious losses.

In this case, the quick service of spindles and electric spindles, parts responsible for the torque of milling machines, lathes or plotters, is crucial for resuming work. Our experienced specialists in the repair of machining components will inspect the malfunctioning mechanism, propose a method of removing the defect, and after acceptance by the customer, they will immediately start working. The element that most often fails is the machine's bearing. Excessive noise and heating may indicate that the most important high speed segment of the machine tool needs urgent repair. The handle mechanism or encoder may also be damaged - then you will also need a quick overhaul of worn parts.

After removing the irregularities, we always proceed to balancing the main part and rotors in the body - thanks to this we make sure that the structure works perfectly. In addition, we guarantee every repair of numerical machines. In addition to work eliminating apparatus defects, we also deal with the regeneration of machine tools.
