Micro Precision Insulating Sleeve is a key component in the MWD system, it is a key non-metallic miniature functional component in the MWD measurement system, used for insulation and precise positioning of electronic and signal modules. The part is small in overall size and thin in wall thickness, with highly consistent miniature window structures on the side walls, requiring extremely high geometric tolerances and surface integrity. Our company utilizes mature micro-machining technology and specialized miniature fixtures to achieve stable machining at such minute dimensions, ensuring reliable performance of the part in high-temperature, high-vibration downhole environments.
Key Technical Challenges
★ Very small overall size and high aspect ratio.
★ Locally ventilated/thin-walled structure, with the thinnest area only a few hundred micrometers.
★ Multi-step shape + micro-irregular profile.
★ Non-metallic or engineering materials, extremely sensitive to the stress and heat effects on the cutting toolmachining. Advanced clamping techniques and control methods are needed to prevent deformation caused by thermal expansion or external forces during machining.
