Spindle Repair Process
Quote & Scheduling
Assembly & Delivery
- Upon arrival, we log every spindle into our production tracking software system and any issues associated with transit are noted.
- Our technicians then carefully break down the spindle into its component parts, note their general condition as well as specific damage, and perform a full dimensional inspection to identify excessive wear.
- Our production manager performs a second evaluation, during which he/she will try to identify the cause of failure, consult with the head of our grinding and machining departments, and determine any recommendations for preventative measures.
- Our purchasing department sources all replacement part costs, determines lead times, and generates a quote.
- Our team gives the quote a final check and communicates it to the customer for approval.
- Following the customer’s approval, we schedule production and order any parts needed for the repair.
- We carefully clean all parts of the spindle and complete any necessary grinding or machining operations.
- Our highly trained technicians then assemble all spindle components and perform a rigorous break-in process. This includes dynamic balancing and thermal/vibration analysis.
- After our inspectors perform a final quality control check, our shipping department carefully boxes the spindle and returns it to the customer.
