此夹头的功能及其对52型车床的重要性

这是一款CNC加工自动车床52型圆孔加长夹头。它能在52型自动车床的主轴中牢固夹持圆棒料,在延伸加工范围的同时不牺牲精度。具体数据:跳动控制在0.005 mm TIR以内,硬度为58 HRC,表面粗糙度保持在Ra 0.4 µm。您能获得循环往复的一致夹持力,标准尺寸产品从我们东莞工厂发货,交期7天。

加长孔如何改善长工件的间隙

此夹头的加长头部相比标准52型夹头增加了25 mm的夹持深度。这一额外长度可支撑长棒料,并在重切削或螺纹加工过程中减少偏摆。您可以将棒料从主轴中伸出更远,这意味着更少的走刀次数和更低的振动。对于轴类、销钉或阀杆等零件,在我们的测试中,这种加长设计可直接缩短高达15%的循环时间。

我们用于实现58 HRC耐久性的材料与热处理工艺

我们采用AISI 4140合金钢。该牌号在韧性和耐磨性之间取得了良好的平衡。在CNC加工内孔和开槽后,我们将夹头淬硬至58 ± 1 HRC。随后进行回火以消除应力,防止高速夹持过程中出现开裂。最后一步是在外表面进行发黑处理,以增强防锈能力并减少与主轴锥度的摩擦。

可指定的内孔尺寸、公差和表面粗糙度

圆孔标准直径范围为5 mm至42 mm,以0.5 mm为增量。无论您的棒料是公制还是英制,我们都能将内孔加工到您的精确尺寸,公差为+0.005 / -0.000 mm。内表面在淬火后进行磨削加工,而非仅车削,这正是我们能达到Ra 0.4 µm的原因。光滑的内孔可减少铝或黄铜等软材料的咬合现象。

每批发货前的检验:跳动与硬度检测

每只夹头在包装前均通过CNC三坐标测量机进行检测。我们在三个深度位置测量内孔直径、锥角以及头部跳动。硬度通过洛氏硬度计在测试片上验证,该测试片与夹头同批次材料加工而成。任何尺寸超出规格的夹头将被报废,而非返工。每笔订单均附带一份打印的检验报告。

东莞精密制造为何能降低您的成本

我们工厂拥有20年的CNC加工和冲压经验。我们配备20台CNC车床专用于夹头生产,这使我们能够将相似尺寸批量生产。这种效率使我们的单价低于欧洲或日本同类产品。而且由于我们是制造商而非贸易商,您可以直接与制造零件的工程师沟通。这是中国制造的精密加工,但采用德式质量控制纪律。

52型锥度和螺纹如何适配您现有的主轴

此夹头采用标准52型锥度,锥角为1:10,配M55 x 2.0拉紧螺纹。它适配大多数52型自动车床,如Citizen、Star和Tsugami等品牌。加长头部为实心结构而非开槽设计,这意味着夹持力仅施加在后部螺纹区域。这种设计可防止夹持长棒料时头部弯曲,保持工件同心度。

包装、交期及原型件最小起订量

标准内孔尺寸在东莞仓库有库存,7天内发货。定制内孔尺寸需要10至12天,因为我们需要在淬火后加工和磨削内孔。我们无最小起订量——您可以订购单件进行测试。每只夹头用防锈纸包裹,放入泡沫内衬,并连同检验报告一起装箱。空运至美国或欧洲需3至5天。

FAQ:为工程师选型此夹头提供的快速解答

测试件的最小起订量是多少?

无最小起订量——您可以订购一件,在您自己的机器上验证配合和跳动,然后再决定批量采购。

能否定制内孔直径和加长长度?

可以,我们可以加工5 mm至42 mm之间的任何内孔直径,并且可以将头部加长至超过25 mm,但最大加长长度为40 mm,以避免负载下弯曲。

如何确保发货后跳动保持在0.005 mm?

我们在同一台机床上一次装夹完成内孔和锥度的磨削,然后用千分表在母体夹持座中夹紧夹头测量跳动——这确保了几何形状的稳定性。

定制内孔尺寸并含热处理的交期是多久?

定制内孔从图纸确认到发货需要12天,因为我们先淬火再磨削内孔至最终公差,这比标准库存产品多出两天时间。

如何下单并在12小时内获得正式报价

将您的图纸或仅内孔尺寸和所加工棒料材质发送给我们。我们的工程师将在12小时内回复正式报价,包括每件精确单价和运费。如需快速参考,请查看我们的CNC刀具选型指南以验证您的刀具配置,并参阅CNC加工公差指南,使您的图纸标注与我们的能力对齐。

将您的询价单发送至sc@bquq.com,或通过WhatsApp发送消息至+86 13713157787。请以PDF或STEP格式附上您的图纸。我们将确认内孔公差、表面处理选项(发黑或本色)以及数量。您将在12小时内获得确定的价格和交货日期,中国时间周一至周六。
