In the realm of precision machining, every minute of "Spindle Downtime" represents lost revenue. For operations utilizing 4th-axis rotary tables, the setup—aligning fixtures and calibrating center heights—is often the most time-consuming bottleneck.
HER-BERT’s BLS Series 4th Axis Quick Change System is engineered to transform this challenge into a competitive advantage.
1. Engineered for Ultimate Rigidity
Leveraging our expertise in material science, the BLS system utilizes the same high-standard FCD60 casting found in our world-renowned power vises. This ensures that even under maximum clamping force or heavy-duty milling, deformation is kept to an absolute minimum.
2. Revolutionary Changeover Efficiency
The BLS series (models BLS-2520 to BLS-6330) allows for Off-Machine Setup. By preparing workpieces on the pallet outside the machine, operators can swap the entire bridge in seconds.
- Reduces setup and fixture changeover time by over 50%.
- Increases machine "Green Light Time."
- Maximizes the ROI of your rotary table investments.
3. Seamless Ecosystem Integration
Our 4th Axis Quick Change System is designed to be the core of your workholding strategy. It integrates perfectly with:
- HER-BERT 5-Axis Self-Centering Vises: For high-precision multi-sided machining.
- Zero-Point Clamping Systems: For sub-second, highly repeatable pallet positioning.
- Pneumatic & Hydraulic Solutions: Catering to both manual and automated production lines.
Applications in Modern Manufacturing
Whether it is for Aerospace, Medical components, or High-Mix/Low-Volume (HMLV) production, the BLS series provides the stability and flexibility required for complex geometries. The high repeatability of our system ensures that your first part is as accurate as your last.
