Theta High-Speed Grinding Spindle Repairs

Theta Precision Co., Ltd. logo

Theta Precision specializes in manufacturing reliable grinding spindles for high-speed applications. Although Theta is known for producing high-quality spindles and sourcing their components from trusted manufacturing partners, including FANUC, NSK, and GMN, it’s not uncommon for them to undergo wear and tear. Because Theta spindles are exclusively used in high-speed applications, they’re more susceptible to bearing degradation, thermal stress, imbalances, and material fatigue.

If you’ve noticed increased vibration levels, overheating, unusual sounds, runout, or other issues with your Theta spindle, you can turn to Superior Spindle for factory-authorized repairs.
