SPINDLE REFURBISHMENT CASE STUDY | MAG BOEHRINGER HEADSTOCK
A Spindle’s performance directly impacts machining accuracy, productivity, and overall machine reliability. Here’s a recent refurbishment case where our team addressed abnormal noise and vibration in a high-speed Spindle used for Machining SS and Cast iron components.
Customer: Leading manufacturer of Windmill Gearboxes & Housings
Spindle Make: MAG BOEHRINGER Headstock
Operating Speed: 300 RPM
Machining Application: Stainless Steel (SS) & Cast Iron
Reported Issue: Abnormal Noise & Vibration
Root Cause Analysis:
During inspection, our team identified coolant ingress from the front side of the spindle, resulting in bearing corrosion/rusting.
This highlighted the importance of proper sealing and bearing condition in maintaining spindle performance and reliability.
Refurbishment Work Carried Out:
Our team performed a comprehensive refurbishment, including:
• Refurbishment of the shaft front and rear end faces
• Refurbishment of the brake drum
• Manufacturing of new NN bearing spacers
• Replacement of O-rings
• Assembly of new bearings with the required pre-load
• Final inspection and verification of spindle parameters as per OEM specifications
Quality & Performance Focus:
The spindle was thoroughly inspected and its critical parameters were verified against OEM specifications to ensure reliable operation after refurbishment.
This case demonstrates our capability to diagnose spindle failures, identify root causes, restore critical components, and rebuild spindles to required performance standards.
