LG Balakrishnan & Bros
Flagged spindle vibration faults 14 days prior to breakdown, raising line balancing OEE by 22%.
Operational Context & Background
LG Balakrishnan & Bros (LGB) operates high-speed automotive chain and precision component manufacturing lines. Maintaining peak spindle health and machine balancing across 24/7 shifts is essential to meet strict Tier-1 automotive delivery windows.
The Core Challenge
Manual operator paper logs were delayed and inaccurate, leading to unpredicted spindle faults, line imbalance, and costly unplanned downtime during peak production shifts.
Identified Plant Floor Gaps:
- ✕Paper-based operator logs suffered from human recording latency and missed micro-stoppages.
- ✕Spindle bearing wear occurred silently until sudden mechanical failure damaged workpieces.
- ✕Line balancing was reactive, forcing supervisors to re-allocate jobs manually after bottlenecks formed.
Calypsion Solution & Deployment
Connected existing machine PLCs directly to LinkEdge gateways and deployed LinkVision for continuous live OEE telemetry, vibration FFT spectrum analysis, and automated alarm triggers.
Deployment Milestones:
- 01Installed non-intrusive LinkEdge sensor nodes on CNC spindle housings and motor drives.
- 02Integrated PROFINET & MTConnect protocol streams from existing Fanuc and Siemens PLCs.
- 03Configured live FFT frequency thresholds on LinkVision to alert maintenance before acoustic failure.
- 04Automated live OEE dashboards accessible across plant floor screens and management consoles.
Verified Plant Outcome
Flagged critical spindle vibration anomalies 14 days prior to cataclysmic breakdown, saving thousands in unplanned maintenance and boosting line balancing efficiency by 22%.
"Automated vibration telemetry caught spindle bearing wear 14 days before acoustic failure, eliminating unexpected line shutdowns and maintaining strict automotive delivery windows."
— VP of Plant Maintenance, LG Balakrishnan & BrosFrequently Asked Technical Questions
How does non-intrusive vibration monitoring work on CNC spindles?
External high-frequency accelerometers and LinkEdge sensor nodes connect to existing Fanuc and Siemens PLCs without interrupting control logic, analyzing live FFT frequency peaks for early bearing degradation.
How does vibration analysis improve line balancing?
By preventing micro-stoppages and unplanned spindle failures, machines operate at predictable cycle times, eliminating bottleneck accumulation across downstream stations.
