정밀 밀링 커터,모든 재료를 가공하는 CNC용 절삭 공구
What Are CNC Boring Tools?
CNC boring tools are high-precision cutting instruments engineered for CNC machining centers and lathes. These specialized tools refine hole dimensions, roundness, and surface finish through rotational cutting – critical for aerospace components, automotive engines, and other tight-tolerance applications. Primary types include roughing boring bars, finishing heads, and adjustable boring systems.
주요 장점
1. 미크론 수준의 정밀도
Featuring carbide shanks with precision adjustment mechanisms, our tools consistently achieve ±0.005mm tolerances – essential for jet engine parts and transmission housings.
2. Extended Tool Longevity
Nano-coatings (TiAlN/AlCrN) combined with optimized edge geometry reduce cutting forces, increasing tool life by 30% versus standard boring bars.
3. Rapid Changeover System
Modular quick-change inserts and boring bars enable instant diameter adjustments, slashing setup time by up to 70% during batch production.
4. Vibration Suppression
Anti-vibration carbide shanks eliminate chatter during deep-hole boring (Depth/Diameter >8:1), ensuring superior surface finishes up to Ra0.8μm.
5. Thermal Management
Internal coolant channels prevent heat buildup during continuous operation, improving chip evacuation and preventing workpiece deformation.
