Kinematic Coupling Type

3-ball kinematic seat (ISO 10360-2 compliant), Hexapod (6-DOF), or magnetic coupling

Product Description

Coordinate Measuring Machine Probe Head utilizes low thermal expansion materials like Invar or titanium alloys, combined with passive damping systems to reduce thermal gradient-induced drift. Integrated temperature sensors feed real-time compensation to maintain positional accuracy during fluctuating thermal loads.

Indexing Angles/Steps

7.5° or 15° increments (manual), 5°–90° (motorized, ±0.5 arc-sec resolution)

Electrical Connection Type

Lemo/TNC connectors, wireless (RF/RFID), or integrated Ethernet (for real-time data)

Environmental Operating Range

Temperature – 15–25°C (±1°C/hr), Humidity – 30–70% RH (non-condensing)

CMM Controller Compatibility

Supports UCC/UC2 (Renishaw), I++ (Zeiss/Leitz), or OEM-specific protocols (e.g., Mitutoyo)

Certification Standard

ISO 10360-2 (CMM performance), ISO 9001, VDI/VDE 2617 (German metrology standards)

Technical Advantages

Coordinate Measuring Machine Probe Head supports mixed-sensor configurations through standardized kinematic autojoint platforms. Electrical pinout and mechanical interfaces are compliant with multi-vendor protocols, enabling seamless switching between tactile, optical, and scanning probes without system-side requalification. 

Coordinate Measuring Machine Probe Head maintains signal integrity at scanning velocities exceeding 300 mm/s via high-bandwidth analog signal conditioning circuits. Low-inertia drive assemblies and damped resonance structures allow dynamic probing without phase distortion or tip bounce under acceleration loads.

Industry Applications

Aerospace Structural Part Inspection

Coordinate Measuring Machine Probe Head validates complex airframe components with tight tolerances on multi-axis geometries and composite-metal assemblies. 

Automotive Powertrain Dimensional Analysis

Used to measure cylinder heads, crankshafts, and engine blocks requiring micron-level flatness, roundness, and position tolerances. 

Precision Mold and Die Validation

Verifies critical mold cavity dimensions, core alignment, and electrode wear in high-accuracy tooling environments. 

Orthopedic Implant Dimensional Verification

Ensures form accuracy in femoral stems, acetabular cups, and spinal cages produced from titanium and cobalt-chrome alloys. 

Semiconductor Equipment Part Inspection

Measures precision components like reticle stages and wafer chucks with sub-micron accuracy requirements in vacuum-compatible assemblies. 

Turbomachinery Blade Profiling

Captures 3D surface contours of turbine blades and vanes for aerodynamic profile validation and wear tracking. 

 

Angular Indexing Precision in Articulated Setups

Coordinate Measuring Machine Probe Head delivers angular positioning accuracy of ±0.1 arcsec via direct-drive motors with encoder feedback. Preloaded anti-backlash gear sets ensure rigid angular hold during articulation, critical for feature re-probing at compound vector orientations. 

Coordinate Measuring Machine Probe Head enables automatic probe module exchange via repeatable magnetic coupling and micro-alignment pins. Interface flatness and coaxiality are maintained within 1 μm, eliminating the need for Z-axis recalibration post tool swap.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure long-term mechanical stability in its Coordinate Measuring Machine Probe Head?

Frigate uses preloaded kinematic joints with hardened steel contact surfaces to eliminate positional drift over extended use. All mating interfaces are precision-lapped to below 1 μm flatness tolerance. Multi-axis preload conditions are tested for cyclic fatigue endurance. This ensures consistent mechanical response during repeated indexing and high-cycle probing. 

 

What kind of probe deflection compensation is implemented in Frigate’s probe heads?

Frigate applies real-time deflection maps calibrated using standard gauge blocks across all articulation angles. These maps are stored in the controller memory for automatic compensation. The system adjusts trigger points based on stylus length, tip force, and vector orientation. This reduces uncertainty in offset-corrected measurements on flexible probes.

 

How does Frigate address signal degradation over long probe head cable paths?

Frigate probe heads use impedance-matched, low-capacitance cables with differential signaling to prevent attenuation. Internal PCB layouts are shielded and grounded to reduce crosstalk. Connectors are high-density and EMI-filtered for industrial environments. Signal integrity is validated with time-domain reflectometry before shipment. 

Can Frigate probe heads support high-speed scanning on complex geometries?

Frigate probe heads are designed with low-inertia moving elements to reduce dynamic error at high accelerations. Internal sensors support analog data acquisition at rates above 1 kHz. Scanning speeds up to 400 mm/s are achievable with low phase lag. This enables accurate surface tracking on freeform and contoured parts.

How does Frigate maintain calibration integrity during automated probe changes?

Each Frigate Coordinate Measuring Machine Probe Head features a magnetic kinematic coupling with repeatability below 1 μm. Calibration values are linked to unique probe IDs stored in the system. During auto-change operations, the controller reloads the correct compensation data. This avoids the need for manual recalibration or requalification steps.
