这些CNC加工钛合金精密零件产自我们在东莞拥有20年历史的工厂。我们可实现±0.005 mm位置公差、Ra 0.4 µm表面光洁度,经处理后的材料硬度可达58 HRC——原型件标准交期5天。如果您正在设计必须承受振动和腐蚀的支架、壳体或结构部件,这就是您应指定的产品线。

我们为何能在如此公差水平下加工钛合金

钛合金不同于铝合金。它加工硬化快且回弹大。我们通过刚性5轴DMG MORI铣床和恒扭矩主轴以降低转速运行来应对——5级钛(Ti-6Al-4V)切削速度绝不超过60 m/min。我们的刀具路径采用摆线铣削以分散热量,因此薄至0.5 mm的薄壁能保持笔直且无烧痕。每批零件均在恒温车间(23°C ±1°C)内加工,即使长达300 mm的零件也能确保您的CNC加工钛合金精密零件保持在±0.005 mm公差范围内。

对于螺纹铣削和孔精加工,我们通过主轴以70 bar压力进行内冷。这可立即冲走切屑,防止切屑焊接——这是钛合金表面撕裂的常见原因。您可获得干净、无毛刺的边缘,无需二次手工处理。在大多数几何形状上,我们将M6孔的位置度控制在0.02 mm以内。

我们常备并每日加工的三种钛合金牌号

我们不会在收到您的图纸后才订购钛合金。我们常备三种牌号的棒材和板材,直径从20 mm到150 mm。2级(工业纯钛)用于耐腐蚀和可焊性要求。5级(Ti-6Al-4V)用于高强度重量比——我们每日加工此牌号。23级(ELI)用于对断裂韧性要求高的医疗和航空航天领域。如果您需要特定的航空航天AMS规格,我们可采购带完整追溯性的认证材料——询价时请向我们索取钢厂证书。

5级钛合金机加工态硬度通常为36 HRC。如果您需要耐磨性,我们可进行固溶时效热处理至48 HRC而不产生变形,因为我们在精加工前对粗加工毛坯进行去应力处理。我们还提供阳极氧化(II型或III型),可在表面形成相当于60 HRC的硬质氧化层——非常适合滑动接触区域。

超越标准Ra 0.4的表面处理选项

所有CNC加工钛合金精密零件的标准表面为Ra 0.4 µm(16微英寸)机加工光洁度。这适用于大多数密封面和轴承孔。对于外观或气动表面,我们提供喷砂处理以获得均匀哑光效果(Ra 0.8),或手工抛光至Ra 0.1 µm镜面效果。我们还可进行钝化处理(ASTM A967),去除游离铁并增强自然氧化层——这对医疗或化工工艺设备至关重要。

如果您需要激光打标UID码或序列号,我们可在同一装夹中完成——无需重新装夹。标记深度控制在0.03 mm ±0.01 mm。我们已验证精加工工艺不会使关键尺寸变化超过0.002 mm。

每次发货前检测:CMM和表面轮廓仪

我们不会仅凭信任发货CNC加工钛合金精密零件。每个零件都进入我们的QC实验室。我们使用Zeiss CMM进行尺寸验证——对照您的图纸检查所有关键孔、位置度和轮廓公差。表面粗糙度使用Mitutoyo轮廓仪在您指定的精确表面上测量。每笔订单均附完整检测报告(PDF),即使是单个原型件也不例外。对于批量生产,我们采用SPC——每第10件抽样并记录趋势数据。如果尺寸出现漂移,我们会在产生更多废品前停机调整。

您还将获得所用钛合金批次的材料测试证书(钢厂证书),涵盖化学成分和机械性能。如果您是航空航天或医疗审核员,我们的追溯系统可将您的零件号关联到其切割所用的具体棒材。

不撕裂的螺纹、螺旋线圈和内部特征

钛合金螺纹是常见失效点。我们使用单刃螺纹铣刀而非丝锥加工内螺纹,这消除了断刀风险并提供2B级配合。对于M2至M12螺纹,我们将中径控制在0.02 mm以内。对于盲孔,我们将螺纹深度控制在±0.5圈。如果您需要螺旋线圈嵌件(如Keensert),我们可在工厂安装并测试拔出力——我们保证100%达到额定规格。

我们还加工深槽(深度可达直径的3倍)和交叉孔,无毛刺。我们的去毛刺工艺结合磨粒流加工和10倍放大镜下手动检查。您不会在任何内部交叉点发现凸起边缘。

为什么BQUQ东莞工厂不是普通加工车间

我们有20年经验,但更重要的是专注。我们只做精密CNC加工——不做注塑、不做压铸。这意味着我们的操作员、刀具设定员和QC人员每天全天候加工高公差钛合金零件。我们的机床配备探针循环系统,每次换刀后自动重新对零,将漂移控制在0.002 mm以内。我们还维护专用钛合金刀具库存(K10/K20硬质合金牌号),绝不会为省钱而使用磨损刀具。

位于东莞使我们能快速获取原材料供应商和涂层服务。但我们不是贸易公司。我们拥有机床和厂房。如果您来访,您会看到运行中的DMG MORI机床和CMM检测室。我们是中国精密制造,从您的收件箱到我们的车间有直接通道。中间没有销售代理。

最小起订量(MOQ)是多少?

无最小起订量——我们接受单个原型件或1000件批量生产,单件装夹成本相同。

能否定制尺寸或添加图纸上没有的特征?

可以,我们可以添加激光打标、钝化、阳极氧化或螺旋线圈嵌件等功能——只需在图纸上注明或通过邮件告知,我们将作为单独项目报价。

你们如何控制钛合金零件的质量?

每个零件均经过CMM关键尺寸检测和表面轮廓仪Ra检测;批量生产采用SPC每第10件抽样,完整报告随货附送。

CNC加工钛合金精密零件的标准交期是多少?

原型件5个工作日内发货,100-500件批量生产12-15个工作日发货,紧急订单可加急至72小时,需加收20%加急费。

如何在12小时内获得正式报价

我们根据您的3D模型(STEP或IGES)和2D PDF报价。请将两者发送给我们——2D图纸用于公差,3D用于几何形状。我们将审查可制造性,如果您不确定材料牌号可提供建议,并发送含交期的正式价格。我们的报价包含刀具、检测和表面处理——无隐藏成本。如果您需要可制造性设计帮助,我们将指出风险特征(深槽、薄壁、盲孔螺纹)并提供不损失功能的成本节约替代方案。

如需在12小时内获得正式报价,请将图纸发送至sc@bquq.com或通过WhatsApp联系+86 13713157787。我们会在一个工作日内回复每份RFQ,通常更快。立即发送您的图纸,看看20年钛合金专家能为您做什么。

在最终确定设计之前,请阅读我们的CNC刀具选择指南以了解刀具几何形状对钛合金的影响,以及我们的CNC加工公差指南以避免过度标注——两者都能为您节省成本。我们期待您的图纸。
