这款36型夹头在您的自动车床上实际发挥什么作用

这是一款CNC加工的自动车床36型带销槽夹头,专为高速走心式和滑动主轴箱车床设计。它可夹持Ø3 mm至Ø36 mm的棒料,同心度跳动≤0.005 mm TIR。这意味着您成品零件的圆度始终保持在5微米以内,循环往复。我们将槽宽和销孔公差控制在±0.003 mm,因此夹头无需垫片或手工修配即可锁入主轴鼻端。由BQUQ在中国制造,拥有20年精密制造经验,标准尺寸7个工作日内发货。

销槽几何形状如何防止夹头在负载下旋转

大多数夹头故障始于旋转。这款36型上的销槽并非装饰性凹槽——它是一个淬硬定位特征。我们将槽宽铣至4.0 mm ±0.005 mm,深度2.5 mm,与主轴中的驱动销匹配。当夹头闭合时,销与槽侧面接合,而非槽底。这能均匀分布扭矩,消除圆夹头常见的“跳动”现象。槽边倒角至0.05 mm半径,确保销顺畅滑入,不会被毛刺卡住。如果您的机器使用不同尺寸的销,请告知我们图纸——我们将按您的规格切割槽。

我们用于36型夹头的材料与热处理工艺

我们不使用易切削低碳钢。本体采用20CrMnTi合金钢,渗碳层深度0.6–0.8 mm。芯部硬度35–40 HRC以保证韧性;表面硬度58–62 HRC以保证耐磨性。内孔在淬火后磨削,而非淬火前。这就是使用寿命6个月与2周之间的区别。我们还提供9Cr18MoV不锈钢全硬版本,适用于腐蚀性冷却液环境——几何形状相同,公差相同。对于弹簧加载型,我们使用65Mn弹簧钢,回火至44–48 HRC,槽在回火后切割以避免变形。

将跳动控制在5微米以下的磨削顺序

跳动不是单一工序——而是一个顺序。我们先粗车外径,然后热处理,再将内孔磨削至Ø36.000 mm +0.005/-0.000。接下来,将夹头压装到精密心轴上(心轴本身磨削至0.002 mm TIR),并将外锥度磨削至1°30' ±2'。销槽最后用线切割加工,因此槽不会使内孔变形。每只夹头均在马波斯测量站上检测:内孔直径、锥度角、槽宽和TIR。我们对所有关键尺寸保持Cpk≥1.33。如果您需要检验报告副本,随箱附送——不额外收费。

每次发货前的检验:我们测量什么

每只夹头都进行全尺寸检测,而非批次抽检。我们测量:三个深度位置的内孔直径、槽宽和深度、销槽相对于内孔轴线的位置、正弦规上的锥度角,以及0.0001 mm千分表上的TIR。表面粗糙度用三丰SJ-210轮廓仪验证——内孔Ra 0.4 µm,锥面Ra 0.8 µm。硬度在洛氏C标尺上于外径两点测试。任何读数超出规格,夹头即报废,不返工。我们还进行100%目视检查,在5倍放大下检查边缘破损和表面缺陷。

为什么36型无需修改即可适配大多数瑞士型车床

此夹头遵循标准ER-36和36型交叉参考尺寸。锥度角1°30',螺纹拉回段为M36 x 1.5,总长60 mm。适用于Citizen、Star、Tsugami以及大多数接受36型的中国自动车床。如果您的主轴使用35 mm或38 mm拉管,外径可调整——只需发送您的图纸。我们常备12种标准尺寸(Ø3、Ø4、Ø5、Ø6、Ø8、Ø10、Ø12、Ø14、Ø16、Ø20、Ø25、Ø32)供当日发货。非标内孔(如Ø7.5 mm)3天内加工完成。

交期、最小起订量及我们如何控制价格

无最小起订量。这是BQUQ所有夹头的长期政策,而非促销活动。标准尺寸7个工作日内发货。相同槽几何形状的定制内孔直径10个工作日内发货。全定制夹头(不同材料、不同槽位、不同锥度)在图纸批准后15个工作日内交货。价格取决于材料和数量。1–10件,单价约$18–$25。100件以上,价格降至$9–$12。我们内部完成CNC车削和磨削,因此没有外包加价。货运通过DHL或FedEx,门到门,至美国或欧盟3–5天。

常见问题:定制槽位和材料选项

您能将销槽做在对面吗?

可以,我们可以将槽位旋转至相对于夹头方向标记的任何角度(0°–360°)——只需在图纸上标明度数即可。

您是否提供用于干式加工的涂层版本?

是的,我们提供内孔和锥面上的TiN或TiAlN涂层,可将表面硬度提升至相当于85 HRC并减少摩擦——非常适合无冷却液加工铝或黄铜。

您如何保证槽边无毛刺?

我们使用线切割加工槽,然后用陶瓷刷将边缘倒角至0.05 mm半径,并在5倍放大下检验——毛刺件被拒收,绝不发货。

我可以在批量订购前获取样品吗?

可以,我们通过DHL快递在确认后24小时内寄送单件样品——样品价格与10件单价相同,但费用将在您的首次批量订单中退还。
