【Product Description in English】
The focusing barrel, as a core component of precision optical instruments and measuring equipment, plays a vital role in achieving accurate focal adjustment and maintaining image clarity in telescopes, microscopes, and theodolites. Manufactured from high-purity aluminum alloy through CNC machining centers, this product combines lightweight design with structural stability, meeting rigorous requirements for high-precision mechanical components in scientific research, industrial inspection, and professional measurement applications.
The aluminum alloy material offers exceptional strength-to-weight ratio and corrosion resistance, ensuring long-term operational reliability while reducing overall equipment weight. Utilizing advanced CNC machining techniques, the product achieves surface roughness below Ra0.8μm, with dimensional tolerances of critical mating surfaces strictly controlled within ±0.01mm. This precision guarantees seamless integration with optical assemblies and mechanical transmission systems. The multi-layer anti-glare thread design effectively minimizes stray light interference, and the modular structure enables quick disassembly for maintenance.
Available in customizable specifications, the product supports inner diameter sizes ranging from Φ28mm to Φ60mm and travel distances from 10mm to 50mm. Specialized surface treatments enhance wear resistance and oxidation protection, making it suitable for challenging environments with high humidity or temperature fluctuations. In medical microscopy applications, its oil-free lubrication design prevents sample contamination, while the all-metal construction withstands repetitive mechanical stress in engineering surveying equipment.
Through optimized transmission ratio design, the focusing knob torque is precisely regulated between 0.2-0.5N·m, ensuring smooth operation while preventing accuracy deviation caused by external forces. The product has undergone rigorous environmental simulation tests, demonstrating stable mechanical performance across temperatures from -20℃ to +80℃. The proprietary anti-backlash locking mechanism effectively eliminates play issues common in conventional focusing mechanisms.
Both versions maintain technical consistency while complying with specified content requirements, avoiding restricted terminology and focusing on product characteristics and application value.
