DN Solutions/Doosan Spindle Repairs

When you turn to Superior Spindle for Doosan spindle repairs, you can expect efficiency every step of the way. Our repair process involves:

• Disassembly (Free):  Our repair process starts with our factory-trained technicians disassembling your spindle in our HEPA Class 10,000 cleanroom to prevent contamination. All components of the spindle are photographed and logged into our quality management system.  

• Evaluation (Free):  Then, our technicians evaluate for signs of internal and external damage, including simple wear and tear, inadequate lubrication, and imbalances. All Doosan spindle inspections are performed using our exclusive ABTech Microform rotary table. These tables are air-bearing, high-precision rotary tables that are optimized for optical analysis and low-speed TIR measurements.  

• Failure Analysis Report & Quote (Free): After inspections are complete, you’ll receive a comprehensive failure analysis report (FAR) and a no-obligation quote. Our FARs include details on which components were damaged, the probable cause of failure, our repair recommendations, and an estimated timeline.

• Repairs: After you accept your quote, we assign your repair to a technician who is specialized in that specific type of repair. If technicians find near-failing or failed components during the evaluation process, they will replace defective parts with OEM parts. Machining and grinding may also be done to ensure spindles meet OEM specifications. After repairs are complete, we thoroughly clean your spindle in our cleanroom before reassembling it. Standard repairs usually take 10 to 14 days, but we do offer expedited services (1 to 3 business days) for emergencies).

• Testing & Balancing: All Doosan spindles are meticulously tested in both extreme and normal operating environments to ensure optimal performance. Spindle tests include, but are not limited to, vibrational testing, thermal analysis, and geometric inspections. All spindle balancing is done to ISO 1940-1:2003(E) specifications.
  
• Quality Assurance (QA) & Free Shipping: Before we ship your Doosan spindle back to you, our technicians will send the spindle to our QA department for a final, definitive inspection. Once our QA team has determined your spindle to be fully functional and operating at its best performance, we send your spindle back to you along with a report that includes a list of all replaced components, maintenance tips, installation recommendations, the probable cause of failure, and the length and results of each test performed by our technicians.
