HSD Spindle Bearing Guide
HSD spindle bearings: when to replace them and how it’s done right. Atlanta Precision Spindles supplies and installs precision angular contact ceramic hybrid bearings for HSD ES, AT, MT, and MTR series spindles. Bearing replacement is performed as part of a full rebuild in our Class 10K clean room — because at 18,000–24,000 RPM, how…
Read MoreHaas UMC 5-Axis Spindle Repair for Aerospace Machining Applications
Modern aerospace manufacturers frequently rely on 5-axis platforms like the Haas UMC-750 and other UMC-series machines to produce high-tolerance aluminum and titanium components. These machines are powerful, flexible, and efficient. But in aerospace environments, spindle stress is significantly higher than many shops realize. And when a spindle drifts out of spec, it rarely announces itself.…
