Just take a look at our detail-oriented and industry-leading inspection process

  • Evaluation & Teardown

    We meticulously disassemble and log each part to adhere to the original manufacturing guidelines.

  • Geometric Inspection

    Each component is chemically cleaned and checked for flaws. At this stage we also start a digital photo record of the inspection to ensure that all quotes are as accurate as possible.

  • Machining & Balancing

    This step is done on our top-of-the-line equipment. Our expert technicians follow the Kaizen continuous improvement program and receive ongoing education. We’re proud to have the most knowledgeable engineers in the industry working for us and creating optimal performance parts for you. All spindles are balanced to
    ISO 21940-11:2016 specifications.

  • Cleanroom Testing & Assembly

    Never heard of this before? We’re not surprised. Most repair shops don’t offer this. Our facility hosts 2 Class 10,000 HEPA climate-controlled cleanrooms for inspection and assembly purposes. This keeps containments from affecting your spindles, retaining the quality of your equipment throughout the entire process.

  • Complete Run-in Test

    All functions are fully documented and tested. Fine tune balancing is set and recorded at your operating speed. Full analyses and final runoff data is sent with every repair and remanufacture we handle.

  • Final Reporting

    A detailed chart of verified dimensions and performance characteristics documents each step in the repair and remanufacturing process. This ensures that your spindle conditions exceed the typical industry standards.
