这款方孔夹头适用于夹持什么材料

这是一款CNC加工的自动车床42型方孔弹簧夹头,用于在走心式及固定主轴式自动车床上夹持方形、矩形或六角形棒料。内孔经过精密磨削,与您的精确方形尺寸匹配,典型对边尺寸范围为4 mm至32 mm。鼻端总跳动量为0.005 mm,即使在8,000 RPM主轴转速下,您的车削零件也能保持在公差范围内。标准规格交期15天,定制内孔交期20天。

42型夹头在方形棒料上失效的原因

圆形夹头会压碎方形棒料。它们仅接触四个角,造成夹持力不均和振动。我们的42型方孔夹头采用全接触设计。内孔经线切割后手工研磨,以匹配您的精确方形尺寸,从而将夹持力均匀分布到四个平面上。我们保证内孔与42 mm锥面之间的同心度在0.003 mm以内。这一数值可确保在重切削时棒料不会后退。

我们使用的材料与热处理工艺

我们采用20CrMnTi合金钢作为原材料,这是高磨损夹头本体的标准材料,因其渗碳性能优异。我们在同一装夹中加工内孔和42 mm锥面,以确保几何精度。随后进行渗碳处理,渗碳层深度为0.8至1.2 mm。夹持表面最终硬度为HRC 58-60,而弹簧槽区域硬度保持在HRC 40-45。这种软背设计使夹头具备所需的弹性,在50,000次循环后槽部也不会开裂。

我们的弹簧槽切割并非直线

大多数夹头在槽根处失效。我们将弹簧槽根部切割为0.3 mm圆角,而非尖角,从而分散应力,使用寿命比标准尖角切割槽延长约40%。槽宽为1.5 mm ± 0.05 mm。在热处理前,我们使用塞规对每个槽进行测量。如果塞规不能以特定阻力滑过,该夹头即被报废,绝无例外。

每次发货前的检验流程

每只夹头均经过三步检验。首先,使用气动量仪验证内孔尺寸——重复精度为0.001 mm。其次,将夹头安装到测试心轴上,使用千分表测量距鼻端10 mm处的跳动量,超过0.005 mm即判定不合格。第三,使用精密比较仪检查锥角。42型锥度为1:10,我们在全长范围内控制在± 0.005 mm以内。每笔订单均附带书面检验报告。

如何订购定制方孔尺寸

我们常备36种标准方形规格,范围从4 mm至32 mm。如果您的方形尺寸为非标规格,请将精确的对边尺寸和圆角半径发送给我们。我们将根据您的图纸进行线切割,并手工研磨至最终尺寸。定制内孔交期为图纸确认后20天。50件以下的定制内孔不收取刀具费用。超过50件,刀具费用完全免除。需要检查您的方形棒料公差?请先阅读我们的CNC加工公差指南,再发送图纸。

出口包装与运输

每只夹头均单独使用VCI防锈纸包裹,并密封于塑料管内,防止海运过程中生锈。每箱装20件,内置泡沫隔层,确保夹头互不接触。纸箱尺寸为40x30x25 cm,重量为12 kg。空运时采用真空密封袋以减小体积。我们从东莞通过DHL、FedEx或海运发货至您的港口。大多数美国和欧盟客户选择空运,因为15天生产加5天运输比本地采购更具优势。
