Laser Ceramic Ring D21.4 M8 H13 OSPRI FC-40 Double Holes Spare Parts
The D21.4 M8 H13 Laser Ceramic Ring is a high-sensitivity, specialized sensing component designed for the latest generation of OSPRI fiber laser cutting heads, specifically the FC-40 series. It serves as a critical insulator and signal transmitter within the capacitive height control system, maintaining the essential gap between the nozzle and the workpiece.
Manufactured by Jinan Allwin CNC Machinery Co., Ltd. (FWINCNC), this spare part features the updated double-hole design, which is engineered for superior signal stability and improved thermal management during high-power cutting operations.
Key Specifications:
- Outer Diameter (D): 21.4mm
- Thread (M): M8
- Height (H): 13mm
- Design: Double Holes (New Version)
- Compatible Model: OSPRI FC-40
Technical Excellence & Features
- Double-Hole Stability: The advanced double-hole architecture of the FC-40 version optimizes air cooling around the sensor and minimizes signal interference, ensuring consistent capacitance feedback even during high-speed, long-duration cuts.
- Exceptional Signal Sensitivity: Utilizing high-purity gold-plated contact pins and premium conductive silver paste, this ring ensures zero-latency communication with the OSPRI height controller, significantly reducing the risk of nozzle-to-plate collisions.
- Industrial Zirconia Ceramic: The body is constructed from high-grade zirconia ceramic, providing excellent heat insulation and mechanical toughness. It remains structurally sound under the intense thermal stress and high-pressure gas environments characteristic of fiber laser cutting.
- Precision M8 Threading: The M8 thread is machined to tight tolerances for an airtight seal, preventing auxiliary gas leakage and ensuring a stable, concentrated jet for high-quality dross-free edges.
Compatibility Guide
This D21.4 M8 H13 specification is the standard for the newest OSPRI autofocus cutting heads:
- OSPRI FC-40: Purpose-built as the primary replacement ceramic for FC-40 laser heads.
- High-Power Fiber Systems: Widely integrated into industrial laser machines that require the specific 21.4mm footprint for compact, high-precision head assemblies.
- OEM Replacement: Ideal for manufacturers and end-users who utilize OSPRI technology in their sheet metal or tube processing lines.
Maintenance & Replacement Tips
To ensure the high-speed tracking performance of your OSPRI system:
- Verify Dimensions: Ensure your current laser head requires the 21.4mm diameter and 13mm height, as these dimensions are specific to the newer FC-40 standard.
- Regular Cleaning: Periodically clean the gold-plated pins and the M8 thread with isopropyl alcohol to remove carbon deposits and maintain high electrical conductivity.
- Inspect for Cracks: Even microscopic cracks in the zirconia body can lead to signal drifting or sensor alarms. Replace the ring immediately if any physical damage is visible.
- Reliable Sourcing: FWINCNC provides factory-direct FC-40 double-hole ceramic rings from our Jinan facility, ensuring peak performance and immediate global availability.
