2025년 정밀 가공에 힘을 실어주는 새로운 품질 생산성, 국산 HSSE 코발트 탭은 고급 의존도를 깨뜨립니다.

1. 전략적 필수 요소: 새로운 품질 생산력(NQPF)

2025년 이후 중국의 산업 전략의 중심인 '신품질 생산력'(NQPF) 개념은 혁신 주도, 고효율, 지속 가능한 발전을 강조한다. 정밀 가공의 영역에서 이는 점점 더 복잡해지는 재료와 더 엄격한 공차를 처리할 수 있는 고성능 절삭 도구에 대한 수요로 직결됩니다. 역사적으로 고급 나사산 작업, 특히 스테인리스강, 티타늄 합금 및 고강도강과 같은 까다로운 재료는 수입에 크게 의존해 왔습니다.

2. 국내 HSS-Co 탭의 기술적 혁신

최근 국내 제조업체가 세계적인 HSS-Co 탭 개발에 성공한 것은 NQPF가 재료 과학 및 도구 기하학에 투자한 직접적인 결과입니다.

재료 및 구성

핵심 혁신은 M35 및 M42 코발트 고속 강철의 야금학을 마스터하는 데 있습니다. 코발트 함량(일반적으로 5%~8%)을 정밀하게 제어하고 열처리 과정을 최적화함으로써 가정용 탭은 이제 표준 HSS 공구에 비해 우수한 경도, 고온 경도 및 내마모성을 달성합니다 [2]. 이를 통해 특히 고온 절단 환경에서 더 높은 절삭 속도와 연장 공구 수명을

 

고급 기하학 및 코팅

현대적인 가정용 HSS-Co 탭은 최적화된 나선형 플루트 및 나선형 포인트 기하학을 특징으로 하며, 우수한 칩 배출과 절삭 토크 감소를 위해 설계되었습니다. 또한 TiAlN(질화 티타늄 알루미늄) 또는 TiCN(탄화 티타늄)과 같은 고급 PVD 코팅의 적용은 열과 마모에 대한 중요한 장벽을 제공하여 건조 또는 최소 수량 윤활(MQL) 가공의 성능을 크게 향상시킵니다 [3].

3. 고급 정밀 가공 애플리케이션 강화

이러한 고성능 국내 HSS-Co 탭을 제조 생태계에 통합함으로써 핵심 정밀 부문에 직접적인 힘을 실어주고 있습니다.

 

• 
항공우주:
 고강도 내열성 슈퍼 합금에서 나사산을 두드리는 데는 탁월한 강도와 열 안정성을 갖춘 도구가 필요합니다. 국내 HSS-Co 탭은 이제 이러한 엄격한 요구 사항을 충족하여 중요한 구성 요소의 위치 지정을 지원하고 있습니다.

• 
자동차:
 전기 자동차(EV) 및 경량화로의 전환에는 알루미늄 및 복합 재료의 정밀한 나사산이 필요합니다. 새 탭의 최적화된 형상은 탭 파손 위험을 최소화하면서 깨끗하고 정확한 나사산을 보장합니다 [4].

• 
몰드 및 다이 메이킹:
 경화 공구 강철의 딥 홀 탭핑의 경우 M35/M42 탭의 우수한 고온 경도를 통해 치수 정확도와 표면 마감을 보장하여 재작업 및 생산 시간을 단축합니다.

4. 하이엔드 의존성과 글로벌 전망 돌파

국내 HSS-Co 탭의 성공은 중요한 이정표를 나타냅니다.
고급 수입 의존성의 산산조각
 중요한 산업 부문에서. 중국 제조업체는 국제 업체의 성능에 맞거나 그 이상의 경쟁력 있는 대안을 제시함으로써 국내 공급망을 확보하는 것은 물론 글로벌 절삭공구 시장의 주요 업체로 자리매김하고 있다. 이러한 변화는 NQPF 전략의 실천을 가시적으로 보여주는 것으로, 산업 자립을 견인하고 혁신을 통해 글로벌 제조 우수성을 촉진합니다.
