• intros：{"brand_intro":"株洲钻石切削刀具股份有限公司（ZCC）是中国硬质合金刀具行业的领军企业，前身为株洲硬质合金厂，始建于1954年。公司拥有国家级企业技术中心和博士后科研工作站，在深孔钻领域拥有30多项发明专利。其核心技术优势在于梯度硬质合金基体技术，使钻头芯部韧性高、表面硬度高。品控理念强调'精益制造'，每批次产品均经过三坐标测量仪抽检。","product_intro":"该产品定位中高端深孔加工市场，主打'高性价比+稳定寿命'。核心卖点：采用梯度烧结工艺，钻头芯部抗扭强度提升40%；刃口采用微负倒棱设计，减少崩刃风险。适用于普通钢、铸铁、铝合金等材料的深孔加工，尤其适合大批量生产场景（如汽车零部件）。与厦门金鹭相比，价格更低，但在加工不锈钢时寿命略短。","key_specs":{"直径范围":"4.0-16.0mm","涂层类型":"TiAlN多层涂层，耐磨性优异","内冷孔数":"单内冷孔，适配标准冷却系统","刃口角度":"118°标准顶角，通用性强","适用材料":"硬度HRC25-45的钢材及铸铁"}}
