Expanding Mandrels
Product Introduction
Mongtec Hydraulic Expansion Mandrels utilize advanced hydrostatic expansion technology to achieve 360° uniform clamping, perfectly balancing high-precision positioning with powerful torque transmission. Featuring quick-clamping and flexible sizing, this solution effectively enhances production efficiency, reduces manufacturing costs, and maximizes machine performance to ensure superior product consistency.
Product Description
Product trial model
Mongtec Expanding Mandrels utilize a hydrostatic expansion mechanism, in which internal fluid pressure
activates an expansion element to achieve uniform 360° elastic deformation. This ensures precise and stable
clamping of workpiece bores or shafts.
Engineered for both accurate positioning and secure torque transmission, the system delivers exceptional
reliability and operational safety in demanding machining environments.
Key features include:
- Interchangeable sleeves for a wide range of workpiece diameters, enabling flexible and efficient production setups.
- A built-in elastic adjustment mechanism and quick-change design that minimize fixture setup time and enhance machine utilization.
- Optimized for reducing manufacturing costs while maximizing machining precision and consistency
By adopting Mongtec’s hydraulic mandrel solutions, manufacturers can unlock the full potential of their machine
tools—boosting productivity and ensuring consistent, high-quality output.
Relationship Between Expansion Range and Clamping Diameter
- The maximum allowable expansion of a hydraulic mandrel must not exceed 3% of the clamping diameter.
- To ensure optimal clamping accuracy and extended service life, the clamping section of the workpiece should have a dimensional tolerance of IT7 grade or better.
