The Spindle Repair Process
The spindle repair process consists of the inspection, analysis, repair, balancing, assembly and testing of your spindle all focused on detail and quality. Quality control is built into each phase of repair, and every step is completed in a state-of-the-art repair and manufacturing facility. If your spindle has failed, the “Fastest Way Back to Maximum Productivity” is a timely and high quality repair in our facility. We will rebuild a complete spindle, or a partial spindle of only a few components. We can manufacture new components.
Inspection and Analyzing
- Technical staff check each spindle that arrives for repair. Each unit is logged in, and a work order is opened. This report follows your spindle along the repair process, detailing all the work that is needed and completed. Each unit is visually inspected prior to disassembly for signs of external damage that may have caused failure.
- Technicians carefully disassemble your unit, paying close attention for signs of contamination, lack of oil, misuse or other signs of failure. Each component is polished to remove any surface rust or damaged high spots. Each component is solvent-washed and air-dried. This all takes place in a dedicated area, so quality control will be maintained.
- In the inspection area, trained technicians inspect and analyze each component. Using state-of-the-art analysis methods, each critical component is then checked for size, run out, alignment and parallelism. After careful inspection, a written report of probable root causes for the spindle’s failure and a method for failure prevention is created.
- Virtually any component can be machined, re-manufactured, or manufactured new in our fully outfitted, state-of-the-art machine shop. Experienced machinists will rebuild or reproduce any part needed. This in-house capability assures quality control and timely return to productivity.
- A fully modernized, climate-controlled grinding area equipped with new state-of-the-art CNC grinding machines operated by skilled machinists, is capable of grinding OD’s, ID’s, and internal and external tapers to 0.000025″ or less TIR. Center hole, surface, rotary and jig grinding capability to tolerances of .000010″ compliment in-house capability to assure quality control.
- Unbalanced components will seriously reduce bearing life and cause a poor finish on your product. Correcting an imbalance problem requires removing or adding weight to the component. Proper spindle balancing improves a spindle’s performance and extends the life of its bearings, in addition to retaining improved quality control on all work. Using the very latest in high-tech computer-controlled balancing equipment, the spindle balancing process is completed first, on all individual rotating components, then on the assembled unit.
- Trained assembly specialists carefully assemble spindles in a dedicated clean room. Using all new bearings, with correct and filtered lubricants, your spindle is assembled. Our team of assembly specialist has over a century of hands-on experience in Spindle Repair. They are trained in all phases of machining, boring, grinding, jig grinding, lathe and CNC machining operations.
- During run-in, your spindle will be brought incrementally up to operating speed in a dedicated clean testing area. Your spindle will be tested to verify speed, vibration, temperature and critical runouts. All critical operating parameters are monitored to ensure that your spindle operates to or exceeds original specifications.
- Stringent standards for quality control are maintained even through the shipping process. If your spindle requires paint, an appropriate color is carefully applied. Your spindle is wrapped in non-reactive material and encased in foam. High-strength shipping cartons are used for added protection during your spindle’s trip back to you. Spindles weighing 125 lbs. or more are shipped in custom-built wooden crates.
