Introduction
Theory is useful, but real-world examples show the true impact of advanced workholding. This case study highlights how a mid-sized manufacturer transformed its CNC shop by adopting self centering vise and zero point systems.
Company Profile
- Industry: Industrial machinery components
- Size: 120 employees, 20 CNC machines
- Challenge: High setup times, scrap rates around 10%, frequent small-batch orders
Problems Before Workholding Upgrade
- Setup Time: Average 25 minutes per batch
- Scrap Rate: 1 in 10 parts out of tolerance
- Limited Automation: Manual alignment prevented robotic loading
Solution Implemented
- Installed hydraulic vise on all vertical machining centers
- Integrated zero point clamping systems for pallets
- Trained operators on rapid reconfiguration and fixture maintenance
Results Achieved
- Setup Time Reduction: From 25 minutes to 6 minutes (76% faster)
- Scrap Rate: Reduced from 10% to 2%
- Machine Utilization: Increased spindle uptime by 22%
- ROI: Investment paid off in under 9 months
Long-Term Benefits
- Flexibility to accept more small-batch, high-margin jobs
- Increased confidence in meeting tight delivery deadlines
- Stronger competitiveness against larger rivals
Conclusion
For mid-sized manufacturers, advanced workholding is not a luxury but a necessity. This case proves that even modest investments in vises and clamp systems can yield exponential gains in productivity, profitability, and customer satisfaction.
