Laser Ceramic Ring D31.8 M8 H32 TRUMPF 254493 260432 Cutting Spare Parts Original OEM
This specialized sensor serves as the critical insulation and signal transmission bridge within the capacitive height control system, ensuring the cutting head maintains a constant distance from complex 3D workpieces.
Manufactured by Jinan Allwin CNC Machinery Co., Ltd. (FWINCNC), this ceramic ring is built to withstand the high-speed multi-axis motion and tight-clearance environments typical of 3D pipe and sheet metal fabrication.
As a critical part of the height sensing assembly, this ceramic ring ensures the insulation and stable transmission of capacitance signals between the nozzle and the laser head, allowing for precise tracking of the metal sheet surface.
Manufactured by Jinan Allwin CNC Machinery Co., Ltd. (FWINCNC), this component is designed to be a high-quality replacement for TRUMPF original parts with part numbers 254493 and 260432.
Key Specifications:
- Outer Diameter (D): 31.8mm
- Thread (M): M8
- Height (H): 32mm
- Core Material: Industrial Zirconia Ceramic & Gold-Plated Copper
Technical Excellence & Features
- OEM Compatibility: This ceramic ring is meticulously crafted to match the exact dimensions and electrical impedance of TRUMPF original specifications (254493/260432), ensuring a seamless fit and immediate restoration of cutting accuracy.
- Ultra-Sensitive Signal Response: Utilizing gold-plated contact pins and high-purity silver paste, the ceramic ring provides zero-latency transmission of the capacitance signal, effectively preventing nozzle collisions during high-speed cutting.
- Exceptional Thermal Stability: The high-grade zirconia material used in this component offers superior heat resistance and a low thermal expansion coefficient, maintaining signal consistency even during high-power industrial operations.
- Precision M8 Threading: The M8 thread is precision-machined to provide an airtight seal, preventing auxiliary gas leakage and maintaining the focus of the gas jet for clean, dross-free cuts.
Ceramic Ring Compatibility Guide
The D31.8 M8 H32 specification is a specialized industrial part primarily compatible with:
- TRUMPF: Specifically designed for TRUMPF TruLaser series and other models utilizing the 254493 or 260432 part numbers.
- High-Power Fiber Laser Systems: Ideal for heavy-duty metal processing environments where TRUMPF cutting technology is the standard.
