To complement our machining capabilities, we have integrated high precision Talyrond 385 roundness testers from Taylor Hobson and CMM systems. These tools verify critical Geometric Dimensioning and Tolerancing (GD&T) parameters, such as concentricity and face runout.
Our Indian technicians undergo specialized training at Setco Taiwan, ensuring that global technical expertise is directly applied to our local manufacturing and repair processes. Every manufactured or rebuilt spindle undergoes extensive dynamic testing across multiple RPM ranges to confirm vibration control, thermal stability, and mechanical reliability. This performance data is documented in a quality report for every unit.
Q. How does your ISO-driven quality framework and testing methodology help deliver consistency across both new spindle manufacturing and rebuild services?
Setcoquality policy enables to standardize performance benchmarks, ensuring that every rebuilt spindle is restored to “like-new” performance. This framework bridges the gap between new manufacturing and rebuilds services by applying identical rigorous testing methodologies and quality checkpoints to both.
Every spindle, whether new or rebuilt, must pass a comprehensive inspection process to verify it meets micron-level precision and OEM specifications. All units undergo a comprehensive run-in procedure under controlled conditions. This includes testing for clamping force, vibration, and thermal stability at maximum operating speeds until fully stabilized.
This standardized document serves as a final quality gate, outlining the specific baseline vibration and testing data for the unit. This data is stored by serial number for future reference and comparison during subsequent service cycles. The framework enforces strict Geometric Dimensioning and Tolerancing (GD&T), maintaining critical parameters like circularity and runout within 0.002mm to ensure consistent reliability.
Global engineering resources and skilled technicians in facilities like Pune and Chennai apply these standardized precision processes locally, backed by the same one-year warranty for both new products and rebuilds.
