这款卡盘能完成标准夹头无法实现的功能

这是一款专为自动车床设计的CNC加工双端夹头,可同时夹持两个工件或两根刀具柄。您将获得0.005mm TIR跳动精度、HRC 58-62硬度以及Ra 0.4的表面光洁度。标准尺寸交期通常为7个工作日,定制孔径为15天。我们从东莞发货,中国制造,无起订量。

双端几何设计为何能将循环时间缩短一半

该卡盘两端均设有夹持孔,并在一次装夹中完成加工。这消除了转塔分度或翻转工件的需要。您只需装载一端进行加工,然后将卡盘旋转180度即可加工第二个特征,无需松开夹紧。淬硬钢卡爪可保持高达8000 N的夹持力。与滑动主轴箱车床上的单端卡盘相比,该设计将非切削时间减少了35%。

我们为卡爪寿命选择的材料及热处理工艺

我们采用42CrMo4合金钢,而非廉价的1045钢。本体预硬化至HRC 28-32以保证可加工性,然后对夹持表面进行磨削。磨削后进行深度为0.3mm的渗氮处理。最终表面硬度为HRC 58-62。渗氮层比整体淬硬但易脆裂的卡盘提供3倍更长的磨损寿命。我们不进行镀铬处理,因为镀铬层剥落会损坏您的主轴锥孔。

跳动控制:我们如何实现0.005mm TIR

跳动精度并非磨削后的附加考虑。我们在五轴CNC上一次装夹加工外径、内孔和两端面,然后使用CBN砂轮在坐标磨床上精磨内孔。每个卡盘均使用插入两端的25mm圆测试棒进行检测。我们记录TIR值并雕刻在卡盘本体上。若读数超过0.005mm,该产品不予发货。

锥度精度及与主轴鼻端的配合

我们提供三种标准锥度安装方式:A2-4、A2-5和A2-6。锥角研磨至AT3公差,优于大多数卡盘使用的AT4标准。这意味着您的卡盘能更深入、更紧密地贴合主轴鼻端。我们还为非标主轴制造定制背板。请将您的主轴图纸发送给我们,我们将匹配锥度和螺栓孔分布圆,精度在0.01mm以内。

每次发货前的检验:我们的测量项目

每个卡盘都经过4步QC检验流程。首先,使用校准气动量规检查锥角。其次,使用内径千分尺测量孔径,精度达±0.002mm。第三,使用千分表在两端进行跳动测试。第四,在卡爪表面三个点使用洛氏硬度计检查硬度。我们保留检验记录5年,并随装箱单通过电子邮件发送PDF副本给您。

如何将这款卡盘与您的切削刀具匹配

如果您使用此卡盘夹持刀具柄,请在订购前检查刀柄硬度和直径公差。刀柄尺寸小0.01mm将导致夹持力降低15%。有关刀具材料和几何形状选择的完整说明,请阅读我们的CNC切削刀具选择指南。如果您用于夹持工件,请注意0.005mm跳动精度仅在您的棒料直线度在0.002mm以内时适用。棒料直线度是需要首先验证的事项。

当您需要比0.005mm更严格的跳动精度时

如果您在图纸中指定,我们可以将内孔研磨至0.003mm TIR。这将增加2天交期并使价格提高12%。对于轴承轴颈或光学支架的精加工操作,这是值得的。有关可实现公差等级及如何指定的深入探讨,请参阅我们的CNC加工公差指南。该指南涵盖了ISO 2768-f与自定义GD&T标注之间的区别。

是否有最低起订量?

无起订量。您可以订购一件用于原型测试,也可以订购500件用于批量生产,单价仅在材料批量大小影响热处理成本时才会变化。

能否为我的零件加工定制内孔轮廓?

可以,我们可以研磨方形、六角形或阶梯形内孔,但内孔必须贯穿卡盘全长,且我们需要带有公差和表面光洁度标注的完整图纸。

发货前如何验证跳动精度?

我们将经过认证的25mm测试棒插入两端,以300 RPM转速旋转卡盘,使用分辨率为0.001mm的千分表记录TIR值,然后将测量值雕刻在卡盘本体上。

定制订单的实际交期是多久?

带A2锥度的标准尺寸7天内发货;定制内孔或非标锥度自图纸批准起需15天,如需5天内到货可提供空运服务。

12小时内获取确定报价
