Laser Ceramic Ring D40.8 M11 H34 BOCI Cutting Nozzle Holder Spare Parts
The D40.8 M11 H34 ceramic ring is an industrial-grade, high-sensitivity sensing component designed for high-power BOCI fiber laser cutting heads. Engineered with premium zirconia ceramic and gold-plated copper internals, it ensures stable insulation and reliable capacitance signal feedback to prevent nozzle collisions during high-speed cutting.
Performance Overview of the D40.8 M11 H34 Sensor
The D40.8 M11 H34 specification is a heavy-duty sensor component engineered for industrial fiber laser cutting heads. Operating as a critical nozzle holder spare part, this sensor ensures stable electrical insulation and reliable transmission of high-frequency signals.
Manufactured by Jinan Allwin CNC Machinery Co., Ltd. (FWINCNC), this specialized ceramic ring is optimized for high-power laser configurations and demanding sheet metal fabrication.
Technical Excellence and Core Advantages
- Heavy-Duty Form Factor: The D40.8mm outer diameter provides exceptional structural strength and an optimal balance for high-wattage fiber laser setups (10kW to 20kW+).
- Stable Capacitance Feedback: Featuring gold-plated contact pins, the part delivers real-time, zero-latency feedback to the height controller. This immediate signal transmission allows the CNC controller to adjust Z-axis movement dynamically, preventing costly nozzle collisions.
- Extreme Thermal Durability: The zirconia ceramic ring body exhibits low thermal expansion and outstanding heat resistance, allowing it to withstand extreme operating temperatures without cracking or signal drift.
- Precision M11 Threading: The M11 thread is precision-machined to ensure a secure mechanical connection and an airtight seal, preventing cutting gas leakage and preserving gas jet alignment.
Compatibility and Industrial Application
This robust specification is a specialized ceramic ring primarily compatible with:
- BOCI: Optimized as a replacement sensor for BOCI high-power fiber laser cutting heads used in heavy metal processing.
- High-Power Systems: Designed for medium-to-high wattage fiber laser cutting machines that process thick structural metals.
- Advanced Industries: Widely used in automotive fabrication, structural steel processing, and heavy industrial sheet metal cutting.
