这款夹头为您的自动车床带来的优势

这是一款CNC加工的自动车床38型方棒料夹头,专为高速车削过程中牢固夹持方形、矩形和六角形棒料而设计。您可获得鼻端0.005 mm的总指示跳动(TIR),这意味着您的成品零件无需返工即可保持公差。标准尺寸在10个工作日内发货,每个夹头均经过58-60 HRC硬化处理,确保长时间夹持寿命。

为什么方棒料需要专用的38型夹头

圆形夹头会压碎方棒料的边角。38型夹头具有与您的棒料精确匹配的机加工方形内孔,将夹持力均匀分布在四个平面上。这可以防止重切削载荷下棒料旋转,并消除材料表面的压痕。我们的方形内孔采用线切割而非拉削加工,因此边角锋利,平面平行度保持在0.003 mm以内。

我们使用的材料与热处理工艺

我们采用8620合金钢作为原材料,然后进行渗碳并硬化至58-60 HRC。硬化层深度为0.8-1.2 mm,提供耐磨表面,同时芯部保持韧性以承受反复回弹。对于定制订单,我们还提供4140预硬钢或不锈钢17-4PH。所有夹头在硬化后进行深冷处理,以稳定微观组织,防止长期使用中的尺寸漂移。

我们如何加工槽口和弹簧动作

38型夹头具有三个由线切割EDM而非铣削加工的泄压槽。这使得槽宽为0.4 mm,无毛刺且无应力集中点。弹簧动作经过调校,在气动压力下闭合0.2 mm,这是夹持6 mm至38 mm方棒料的最佳点。我们在包装前对每个夹头在0.3 MPa气压下进行开闭力测试。

每次发货前的检验

每个夹头均使用蔡司三坐标测量机进行100%尺寸检测。我们测量每个单元的内孔尺寸、同心度和槽宽。跳动通过精密测试心轴配合0.001 mm千分表进行验证。我们还对鼻端和锥面进行硬度测试。任何不合格的夹头将被报废,绝不会交付给客户。每笔订单均附带可追溯的检验报告。

与您机床的兼容性和安装说明

此夹头匹配Citizen、Star和Tsugami等品牌的38型标准自动车床主轴。锥角为16度,头部直径为38.0 mm,公差为-0.02 mm,确保紧密配合。我们还提供拉回式和死长度式。如果您的机床使用不同的拉杆螺纹,我们可在3天内加工后端以匹配您的拉杆。

定制尺寸订购,无最小起订量限制

我们不强制您购买100件。6 mm至38 mm尺寸的标准起订量为1件。对于定制内孔形状(如六角或键槽),我们要求5件以覆盖设置时间。所有定制夹头均在东莞工厂从实心棒料加工而成,因此您可获得与标准尺寸相同的10天交货期。目录尺寸永不设起订量。

供您图纸审核的硬性数据

| 参数 | 数值 | |---|---| | 材料 | 8620合金钢(表面渗碳) | | 硬度 | 58-60 HRC(硬化层深度0.8-1.2 mm) | | 内孔尺寸范围 | 6 mm - 38 mm方形、六角或圆形 | | 鼻端TIR(跳动) | 最大0.005 mm | | 锥角 | 16度 | | 头部直径 | 38.0 mm(-0.02 mm) | | 表面粗糙度 | 内孔Ra 0.4 µm,锥面Ra 0.8 µm | | 槽宽 | 0.4 mm(线切割EDM) | | 交货期(标准) | 10个工作日 | | 交货期(定制内孔) | 12个工作日 | | 起订量 | 1件(标准),5件(定制形状) |

从原材料棒料到成品夹头的质量控制

我们从具有钢厂检验报告的认证材料开始。CNC车削和线切割EDM开槽后,每个夹头在190°C下进行2小时去应力处理。锥面和内孔的最终磨削在一次装夹中完成,以避免同心度误差。发货前,我们对内孔尺寸进行100%气动量仪检测。如果您的图纸要求比0.005 mm更严格的跳动,我们可通过研磨达到0.003 mm,但这会增加3天交货时间。

此夹头的起订量是多少?

标准尺寸无起订量——您可为原型或维护需求订购一件。

能否为非标准方棒料尺寸制作夹头?

可以,我们可加工6 mm至38 mm范围内的任何方形、六角或矩形定制内孔尺寸,定制形状最低5件起订。

如何验证成品夹头的跳动?

我们将每个夹头安装在精密测试心轴上,使用0.001 mm千分表测量TIR,并将数值记录在您的检验报告中。

定制38型夹头的典型交货期是多久?

标准尺寸在10个工作日内发货;定制内孔形状在图纸批准后12个工作日内交货。

12小时内获得确定报价

将您的图纸或仅提供棒料尺寸和机床型号发送给我们。我们将在12小时内发送确定价格和交货期,而非模糊估算。我们位于中国东莞的团队直接处理您的询价——无销售代理,无加价。将您的图纸发送至sc@bquq.com或通过WhatsApp联系我们:+86 13713157787。如需更多关于将此夹头与您的切削刀具匹配的信息,请阅读我们的CNC切削刀具选择指南。如果您正在为下一个项目设置公差,请查看我们的CNC加工公差指南
