Learn more about universal holding fixtures and how MICADO's innovative solutions make it a global leader in the aerospace and automotive industries.
What are universal holding fixtures (UHF)?
In the modern manufacturing of complex components for aerospace and automotive, the industry faces a unique challenge:
How can different component geometries be clamped efficiently and precisely without having to manufacture a specific fixture for each individual part? The answer lies in universal holding fixtures.
Unlike conventional holding fixtures that secure the component over its entire surface, universal holding fixtures rely on an intelligent system of vacuum suction cups. These adapt actively or passively to the local curvature of the component and are raised to the appropriate height in one dimension by actuators. The surface of the component to be clamped is thus replicated at specific points, typically at grid intervals of 200mm to 500mm.
The key feature: A single such fixture can be used for an entire family of components, which is why it is referred to as "universal".
The advantages of MICADO's universal holding fixtures
MICADO is one of the world's leading providers of universal holding fixtures and has made a name for itself in the industry through continuous innovation. The advantages of our solutions are numerous:
Flexibility and Cost-Effectiveness
- Customizable table size and individually positionable actuators
- One fixture for multiple component geometries
- Significant cost reduction compared to component-specific solutions
Robustness and Precision
- High rigidity for demanding drilling and milling operations
- Accuracy up to 0.1mm
- Sealed for wet machining
- Low maintenance due to high-quality components
Technological flexibility
- Stroke length up to 2 meters possible
- Multi-end effector systems
- Swiveling suction cups
- Quick and easy actuator replacement
Active or Passive: The right solution for every requirement
Depending on the specific requirements and the underlying production process, MICADO offers two system variants:
Passive Systems: Cost-efficient and robust
Passive universal clamping devices rely on pneumatically driven actuators and are characterized by their robustness:
- The actuators move sequentially, with the milling machine defining the end position as a stopper
- Direct integration into the CNC machine possible without a separate control system
- Very robust and reliable, even in high-moisture environments
- Cost-effective solution while maintaining very high accuracy
- Control is directly managed by the CNC machine
Active Systems: Fast and flexible
Active systems with servo drive and BECKHOFF control offer maximum flexibility:
- All actuators operate synchronously and minimize setup time
- Retracts can be performed during milling to prevent collisions with the milling head
- Active forming: The actuators can pull or push the component into the desired shape
- Intuitive operation via HMI (Human Machine Interface)
- Ideal for complex machining cycles and frequent part changes

Individual actuator positions for optimal results
A key advantage of MICADO systems is the flexibility in actuator positioning. If the components are known at the start of the project, the actuators can be perfectly adapted to their shape and requirements.
The result is compelling:
- Reduced number of suction cups required
- Maximum clamping quality
- Precise, collision-free positioning close to the milling tool
- Quick and efficient implementation of simple grid positioning, if needed
A wide range of end effectors for maximum adaptability
The versatility of MICADO clamping devices is particularly evident in the selection of end effectors. As an alternative to the proven round suction cups, an individual hard tool can be attached at any position:
MICADO Vacuum Suction Cups
- Freely movable
- Various sizes available
- Ideal for curved surfaces
- Even force distribution
Hard Tools
- For surface support
- Precise component alignment
- Improved component support in the monolithic area
- Preventing vibrations during machining
This combination makes component positioning particularly easy while ensuring optimal stability during machining.
The importance of professional consultation
"Especially for universal vacuum clamping fixtures, professional consultation is crucial for project success," emphasizes Ing. Markus Rath, Head of Tool & Fixture Construction at MICADO.
The selection of the right solution depends on numerous factors:
- Component geometry and family
- Machining type and process
- Cycle time and production volume
- Environmental conditions
- Budget and ROI requirements
Through years of collaboration with renowned Tier 1 suppliers in the aerospace industry, MICADO possesses extensive expertise. Tool design always takes place in close coordination with the customers' technicians.
