产品名称:淬硬钢圆柱销、定位销
执行标准:DIN EN ISO 8734 - 2019
产品概述:圆柱销也可以叫定位销,平行销,这类标准整合了国际、欧洲和德国的技术要求,让圆柱销的尺寸、公差、材料和硬度在全球范围内有了统一的验收依据,消除了不同国家和厂商之间的技术壁垒 ,标准的通用性让不同厂商生产的圆柱销可以直接互换,大幅降低了采购、库存和维修的成本。淬硬钢又分为整体淬硬与表面淬硬,整体淬硬的硬度为550-650HV30,表面淬硬的硬度为:600-700HV1,渗碳层厚度为0.25-0.4mm。DIN EN ISO 8734这个标准替代了之前的DIN 6325 是旧版德标,取消 A/B 型端部区分,允许冷镦成型。通过严格的直径公差,表面粗糙度要求(Ra≤0.8μm),确保圆柱销与配合孔的间隙极小,从而实现零件间的精准定位,保证设备的运行精度。
产品表面:表面多以磨削本色为主,如需电镀表面时,需要及时驱氢处理,以防其他部门处理产生氢脆现象。
产品直径:φ1-φ20mm 直径公差参考:ISO268-2轴公差上下限值
