Our Spindle Reconditioning Process

Superior Spindle is K+S Services’ in-house spindle repair facility with machining, motor rewinding, and feedback repair capabilities. Most repairs can be completed within 14 days, but we offer expedited timelines between 1 and 3 days based on part availability. K+S Services stocks over $5 million worth of spares in-house, but certain obsolete models may require individual components to be remanufactured. Whether your spindle needs reconditioned or entirely rebuilt, our process can be broken down in to five primary steps:

Kessler Spindle repair
Step 1

Evaluation:

Our factory-certified technicians disassemble your spindle, chemically clean components, and inspect them for flaws and damage. Evaluations are free and performed in our Class 10,000 HEPA climate-controlled cleanroom to prevent contamination. Damaged components are photographed and documented.

Step 2

Analysis Report:

You’ll receive a Failure Analysis Report at no additional cost. This report documents what our technicians found during the assessment, any probable causes of failure and recommended solutions, a cost estimate, and a repair timeline.

Step 3

Repair:

Spindles are reconditioned to meet OEM performance specs or rebuilt based on application needs. Any damaged parts are replaced with OEM or OEM-equivalent spares.

Step 4

Diagnostics:

Spindles are recalibrated in our cleanroom, then dynamically balanced and fully tested. Our expert technicians follow the Kaizen continuous improvement program and receive ongoing education.

Step 5

Post-Repair:

You’ll receive your reconditioned or rebuilt spindle, along with a 12-month in-service warranty, maintenance recommendations, final runoff data from our testing, and a detailed report highlighting the work our technicians performed.
