这是来自BQUQ位于中国东莞、拥有20年历史工厂的铝合金CNC加工服务。您将获得标准公差±0.005 mm、表面粗糙度低至Ra 0.4的机加工零件,原型交期仅需7天。我们可保持6061-T6硬度达HRC 45,7075-T6硬度达HRC 55,确保您的零件在高应力循环下不变形。

为什么6061-T6和7075-T6主导我们的铝合金CNC加工

我们80%的订单使用6061-T6,因为它焊接性能优异且阳极氧化均匀。对于航空航天或高负载支架,我们改用7075-T6——其屈服强度为503 MPa,几乎是标准6061的两倍。两种材料均附带钢厂证书,我们使用洛氏硬度计对每批来料进行硬度验证。如果您需要其他合金,我们可在48小时内本地采购。

主轴跳动控制在2微米以内,确保真圆度

我们的4轴和5轴CNC加工中心采用带陶瓷轴承的HSK-63A主轴。我们每周一上午使用激光干涉仪测量主轴跳动。结果是:您的孔和轴承座圆度可达0.003 mm,而非旧机床常见的0.01 mm。我们还在加工过程中对每个零件进行在线探测,确保12 mm的孔保持12.000 mm,绝不会变成12.015 mm。

刀具选择:我们日常使用的硬质合金牌号和涂层

对于铝合金,我们使用无涂层微晶粒硬质合金立铣刀,采用45度螺旋角以利于排屑。对于深腔零件,我们改用TiB2涂层刀具,以抵抗积屑瘤。我们的刀具库包含120多种标准刀具,并根据壁厚将转速调整至8,000至20,000 RPM。如果您不确定哪种刀具适合您的几何形状,请在发送图纸前阅读我们的CNC刀具选择指南

去毛刺和表面处理:从Ra 0.4到喷砂

每个铝合金CNC加工零件都经过两步去毛刺:首先进行机器人倒角,然后使用3倍放大镜进行人工检查。对于外观表面,我们标配Ra 0.4 µm——这接近光学支架的镜面效果。如果您想要哑光外观,我们使用120目玻璃珠进行喷砂处理。对于热应用场景,我们增加18-20微米厚的透明阳极氧化层,同时可将表面硬度提升至HRC 60。

每次发货前检测:三坐标测量机、高度规和表面粗糙度仪

没有完整报告我们绝不发货。每批零件都经过蔡司三坐标测量机进行GD&T检测——包括位置度、平面度和平行度。三丰表面粗糙度仪在每个面三个点验证Ra值。我们还对每个螺纹孔进行100%通止规检查。检测报告随装箱单通过电子邮件发送给您。如果尺寸不合格,我们将免费重新加工,绝不使用垫片修补。

交期分解:原型7天,批量生产15天

我们的铝合金CNC加工交期为:10件以内7天,含表面处理和检测。100至500件,从图纸批准到发货预计15天。我们实行两班制,周一至周六每天运行22小时。如果您需要加急订单,我们可以安排3天原型插单,需额外收取15%附加费——但90%的订单无需加急即可按时交付。有关公差限制的更多详情,请参阅我们的CNC加工公差指南

包装和运输:泡沫内衬和出口级纸箱

成品零件先用VCI防锈纸包裹以防氧化,然后放入定制切割的EVA泡沫中,再装入双壁纸箱。数量超过50 kg时,我们使用带钢带加固的胶合板木箱。我们通过DHL、FedEx或从深圳港海运发货。大多数美国和欧盟订单通过空运在5-7个工作日内送达。提货前您将收到追踪号码和密封木箱的照片。

阳极氧化和二次加工:我们内部完成

我们的工厂拥有阳极氧化生产线——Type II透明、黑色和硬质氧化(Type III)。我们还提供丝网印刷、激光雕刻和压入式嵌件服务。由于这些工序在同一厂区内完成,您可避免机加工和表面处理供应商之间3-5天的运输延误。对于硬质阳极氧化,我们将厚度控制在40-50微米,介电击穿电压高于800V。

铝合金CNC加工的最小起订量是多少?

无起订量——我们以100件批量相同的单价加工单件原型,标准合金不收取设置费。

能否根据我的应用定制合金或回火状态?

可以,我们可为疲劳关键零件改用2024-T351,或为超平底板改用MIC-6,并根据您的应力和腐蚀要求指定回火状态。

如何确保紧公差特征的品质?

我们使用机床在线探测加最终三坐标测量机报告;任何超差尺寸在发货前都会重新加工,绝不豁免。

50件批量订单的最快交期是多少?

如果您在24小时内批准图纸和材料,我们可在10天内发货50件——这包括阳极氧化和检测。

立即发送您的图纸,12小时内获得正式报价。发送邮件至sc@bquq.com或通过WhatsApp联系+86 13713157787。我们将回复DFM审查、精确价格和交货日期——绝无意外。这就是中国制造的精密加工,无起订量,每个零件背后都有20年的机加工经验。
