这款夹头是什么,为何能缩短您的装夹时间

这是一款专为高速棒料送料和二次加工工序设计的CNC加工自动车床25型圆孔弹簧夹头。我们保证总指示跳动(TIR)为0.005 mm,硬度为HRC 58-60,这意味着您的刀具或工件在数千次循环中始终保持同心。标准交期为图纸确认后5个工作日,我们从东莞工厂发货至全球。

25型圆孔设计如何消除振刀

25型指的是前锥角和本体几何形状,用于安装到您的自动车床主轴上。圆孔在热处理后进行磨削,而非之前,因此内径公差可保持在+0.005 / -0.000 mm以内。这消除了廉价先磨后淬火夹头常见的“喇叭口”效应。弹簧夹头动作将夹紧力均匀分布在360度范围内,可防止薄壁零件变形,并在高达8,000 RPM的主轴转速下消除刀具振刀。

可承受1,000,000次循环的材料选择与热处理

我们采用20CrMnTi合金钢制造本体,65Mn弹簧钢制造夹头瓣片。本体经过渗碳处理,渗碳层深度为0.8 - 1.2 mm,然后淬硬至HRC 58-60。弹簧槽在淬火后采用线切割加工,以避免应力集中。随后,每个产品在-120°C下进行4小时深冷处理,以转化残余奥氏体,这就是我们的夹头在100万次开合循环后夹紧力保持率仍在5%以内的原因。内孔和锥面的表面粗糙度为Ra 0.4 µm,外表面采用发黑处理以提高耐腐蚀性。

东莞工厂每批发货前的检验流程

我们不进行抽检。每一只夹头都经过3道质量关卡。首先,三坐标测量机(CMM)检测锥角及内孔同心度。其次,我们将夹头安装到实际测试主轴上,使用激光干涉仪测量TIR——您将在QC报告中看到实际的跳动读数。第三,我们在气压下对夹头进行500次循环测试,以验证弹簧回弹力和槽体完整性。任何一件不合格品都将报废,绝不返修。这就是我们能够提供0.3%现场故障率保证的原因。

直接改装到您的25型自动车床上,无需任何改动

这款夹头采用标准的25型后拉锥度设计,可直接安装到大多数日本和韩国自动车床(Citizen、Star、Tsugami、Hanwha)上,无需任何转接板。圆孔可夹持Ø3 mm至Ø25 mm的圆棒料。如果您的主轴使用不同的拉杆螺纹,我们可以免费加工后部螺纹(M16、M18、M20或5/8"-18)。只需将您的拉杆图纸发送给我们,我们将精确匹配螺纹螺距。

为什么我们的CNC加工自动车床25型圆孔弹簧夹头优于铸造或铣削版本

铸造夹头存在气孔,在循环载荷下会导致微裂纹。铣削夹头会留下刀具痕迹,容易滞留切削液并导致腐蚀。我们的夹头完全由实心棒料CNC加工而成,然后进行线切割和磨削。这是中国制造的精密加工,但工艺控制水平与瑞士工厂相当。结果是夹头在至少300,000次循环内无需重新磨削即可保持额定TIR。而且因为我们是工厂而非贸易公司,您能以直接成本获得这种品质——通常比美国或欧洲同类产品低20-30%。

这款夹头真的没有起订量吗?

是的,没有起订量——您可以订购单个CNC加工自动车床25型圆孔弹簧夹头用于打样或产线试运行,我们将以与1,000件订单相同的检验标准对待。

能否根据我的特定车床定制孔径和螺纹?

可以,我们可以磨削Ø3 mm至Ø25 mm之间的任意圆孔,并且可以在收到您的图纸后24小时内加工任何后部螺纹(公制或英制)以匹配您的拉杆。

每批货物随附哪些质量控制文件?

每批货物均包含材料证书、硬度测试报告、CMM尺寸报告,以及带有您夹头序列号的实际运行TIR测量表。

定制25型夹头的实际交期是多少?

标准尺寸5个工作日内发货;定制孔径或螺纹增加2-3天,因此从图纸确认到从东莞发货最长不超过8个工作日。
