概述

您的图纸决定孔径,其余部分由我们加工匹配。这是一款20型方孔弹簧夹头,专为要求同心夹持和可重复释放的自动车床设计。我们从实心棒料切割加工,经热处理赋予弹簧记忆效应,并在出货前验证方孔几何精度。

没有猜测,没有现成标准件的妥协。您提供图纸,我们保证公差。

概览: 孔径尺寸公差±0.005 mm,交期10-15个工作日,无最小起订量,每批附带材质证书。

定制CNC夹头卡盘自动车床六角内孔夹头套装 15-52mm

所有夹头在粗加工后、最终磨削前均进行去应力处理。这可以防止夹头在每班数千次夹紧和释放过程中发生变形。


客户选择将图纸交给我们的三大理由

1. 批次可追溯的质量,而非一次性样品。 每只夹头都有唯一的批次编号。我们将材料炉号、热处理炉记录和最终检验数据与该编号对应存档。如果您的生产线出现需要追溯的问题,可以精确回溯到对应批次和对应机加工周期。当您24/7运行自动车床时,一只不良夹头就可能导致整条产线停机,这一点至关重要。

2. 每批附检验报告,免费提供。 我们发出的每一批货物都附带尺寸报告,列明方孔宽度、圆角半径、同心度、硬度和表面粗糙度。我们不要求您盲目信任,我们提供数据。如果尺寸超出规格,我们会在包装前发现,而不是等您装到主轴上之后才发现。

3. 同一工厂完成CNC加工、冲压、弹簧和散热器。 您的夹头不是孤立的零件。它工作在卡盘内部,而卡盘可能同时使用弹簧、冲压保持架或用于热稳定性的散热器。我们在同一工厂内制造所有这些部件。您只需提交一套图纸,对接一个质量团队,收到一次整合发货。更少的供应商,更少的交接失误,更短的总交期。


应用场景

20型方孔弹簧夹头并非通用工具,而是专为自动车床和走心式机床设计的,用于送进方形或矩形棒料。典型应用包括:

  • 方形铜棒和铝棒送料,用于大批量自动车床加工电气端子及连接器。
  • 六角钢和方钢棒料,用于螺丝机生产紧固件、接头和阀门零件。
  • 旧式凸轮自动车床的卡盘改造,当原装夹头已无法采购时。
  • CNC车床的二次加工,方孔夹头夹持预加工好的方形零件进行钻孔、攻丝或铣削。

方孔结构可防止工件在切削扭矩下发生旋转。与带紧定螺钉的圆孔夹头不同,方形几何结构通过夹头本体直接传递扭矩,从而减少夹头磨损,并提高横向钻孔或铣削特征的定位重复精度。


客户下单前常见问题

问:真的没有最小起订量吗? 答:是的,没有最小起订量。我们可以按您的图纸加工单件原型夹头,也可以生产5,000件。单价随数量递减,但首件检验标准始终相同。许多客户先订购一件,在实际主轴上验证配合和同心度。

问:方孔能达到什么公差? 答:方孔宽度和圆角半径为±0.005 mm。孔径与锥度之间的同心度控制在≤0.01 mm TIR。如果您的图纸要求更严格的公差,我们可以讨论磨削工艺,但±0.005 mm是我们20型夹头的标准精度。

问:多久能收到零件? 答:标准弹簧钢或合金钢为10-15个工作日。不锈钢增加5天。如果因产线停机需要加急,请致电我们。我们有时可以拆分批次,先空运首批零件。

问:你们提供材质证书吗? 答:是的,每批出货都附带原材料钢厂证书和我们自己的热处理报告。记录保存10年。如果您的客户要求完整可追溯性,我们可以提供PDF或纸质版本。
