Step-by-step repair and rebuild
The spindle is the heart of modern machine tool
When it stops, so does production and profitability. Which is why SKF applies a rigid, step-by-step process for every job. We keep a laser-focus on quality – and keep your spindle downtime minimal.
We use ABEC-7 and ABEC-9 precision bearings, equal to or better than the originals, and, when the application demands, ceramic hybrid bearings. Quality control is built into every phase of repair, and every step is completed on-site in our state-of-the-art repair and manufacturing facilities. Our process includes:
Our technical staff checks every spindle that arrives for repair. Each unit is visually inspected prior to disassembly for signs of external damage that might have caused failure. Every unit is logged in, and a work order opened. This work order will follow your spindle through each step of the repair process, detailing the work that is needed and completed.
In a dedicated area designed to maintain quality control, our technicians carefully disassemble your unit, looking for signs of contamination, lack of oil, misuse, or other apparent signs of failure. Once the spindle is completely disassembled, each component is polished to remove surface rust or damaged high spots. Each component is then solvent-washed and air-dried.
MachiningVirtually any component can be machined, remanufactured, or manufactured new in our fully outfitted, state-of-the-art machine shops. Experienced SKF machinists will rebuild or reproduce any part you need. This in-house SKF capability assures quality control and your timely return to productivity.
GrindingSKF operates a modern, climate-controlled grinding area equipped with new state-of-the-art grinding machines. These machines are capable of grinding to very precise tolerances, including ODs, IDs, and internal and external tapers to .000025" or less TIR. We also have center hole, surface, rotary and jig grinding capability to tolerances of .000010". Again, this in-house capability assists in quality control and your timely return to productivity.
Unbalanced components will seriously reduce bearing life and cause a poor finish on the final product. Correcting an imbalance requires removing or adding weight to the component. Proper balancing will significantly improve a spindle's performance and extend the life of its bearings, in addition to maintaining improved quality on all work.
Using the latest computer-controlled balancing equipment, SKF performs the balancing process in steps. When all the components are assembled, the unit's balance is rechecked and corrected as necessary.
