Our CNC Spindle Rebuild Process

Every rebuild follows a rigorous, multi-step process performed by factory-trained engineers in a controlled environment.

  • Thorough Inspection and Cleaning: Each spindle undergoes a meticulous examination to identify wear and damage before any work begins.
  • Component Replacement: We replace all bearings, preload collars, and O-rings with components that meet or exceed OEM standards.
  • Precision Assembly: Spindles are assembled in a clean room environment, ensuring optimal performance and contamination-free results.
  • Drawbar Service: Where applicable, the drawbar is cleaned, greased, and tested for secure tool retention.
  • Quality Assurance: Final inspections and performance tests guarantee your spindle operates at peak efficiency before it leaves our facility.

Our Documentation Standard: Full Transparency at Every Step

This is where Ellison’s spindle rebuild process stands apart from the competition. Every single rebuild is thoroughly photographed and documented at every stage — from the moment your spindle arrives to the moment it ships back to you.

Our documentation includes:

  • Arrival condition photos — visual record of the spindle as received
  • Disassembly documentation — each component catalogued before removal
  • Inspection findings — detailed notes on wear, damage, and measurements
  • Performance measurements — pre- and post-rebuild data on tolerances and specs
  • Reassembly photos — step-by-step visual record of the rebuild
  • Final packaging documentation — confirmation of packaging standards before shipment

You receive a complete record with your rebuild — no guesswork, full accountability. It’s the standard we hold ourselves to on every job, every time.

I've been working with Kim on a spindle rebuild for my NT4250 and I wanted to let you know it was a pleasure working with her. She was very prompt with replies to any questions I had, she's very pleasant to work with, thanks.
