此CNC车削服务为您车床零件带来的价值

这是一项CNC车削服务,我们使用2轴和3轴车床从棒料或毛坯加工圆柱形零件。您将获得直径公差为±0.005 mm、表面光洁度低至Ra 0.4、关键直径总跳动量为0.01 mm的圆形零件。标准材料典型交货期为7天,我们从东莞工厂发货,拥有20年精密制造经验。

我们的CNC车床如何确保每个直径的0.01 mm跳动量

跳动量并非偶然。我们使用液压卡盘和带预紧轴承的动力刀具。每批次加工前,我们用千分表测量主轴跳动——读数必须低于0.003 mm。然后加工测试环,在三坐标测量机上检查,之后才开始生产。对于长轴,我们使用中心架防止挠曲变形,因此我们能在长达400 mm的零件上保持0.01 mm的总跳动量。如果您需要更高精度,我们有坐标磨床工序可达到0.005 mm,但这会增加2天交货期。

我们备有的车床加工材料和热处理

我们备有6061-T6铝、303和316不锈钢、12L14易切削钢以及S45C中碳钢圆棒料。对于需要淬硬的零件,我们先在软态下加工,然后外发热处理至28-32 HRC、38-42 HRC或48-52 HRC。热处理后,我们对外径和内孔进行最终磨削以恢复公差。我们还加工用于电气元件的黄铜C36000和紫铜C11000。如果您的图纸要求我们未备有的材料,我们可在3-4天内采购——发送图纸时请告知我们。

表面光洁度和去毛刺:超越Ra 0.4标准

我们的标准车削光洁度为Ra 1.6,但我们通常使用修光刃刀片和二次精加工工序达到Ra 0.4。对于密封面或轴承轴颈,我们可以抛光至Ra 0.2。所有零件都经过手动去毛刺工位——我们使用显微镜检查交叉孔和螺纹的边角倒圆。除非您的图纸明确要求,否则我们不会交付锐边。对于外观表面,我们提供透明阳极氧化或发黑处理,但这会增加3天工期。

每次发货前检验:CMM报告和材质证书

每批次都有首件检验报告。我们在蔡司CMM上测量所有关键尺寸,用粗糙度仪记录表面光洁度,并在V形块上检查跳动量。您随货收到PDF格式报告。对于不锈钢和铝材,我们附带钢厂测试证书。如果您需要PPAP三级,我们可以提供——只需在询价时告知我们。我们保存检验记录10年,因此任何零件都可追溯到原材料批次和操作员。

螺纹加工、切槽和钻孔:一次装夹完成

我们的车床配备动力刀具,因此无需二次装夹即可铣削平面、钻交叉孔和切削螺纹。这消除了重新装夹误差并降低了单件成本。对于螺纹,我们使用单点刀片加工0.5 mm至2.5 mm螺距,并可加工至M2的内螺纹。当您的设计需要时,我们还使用四爪卡盘进行偏心车削。如果您的复杂零件需要同时进行车削和铣削,我们会建议哪些特征留在车床上加工,哪些转到我们的5轴CNC铣床上——请参阅我们的CNC刀具选择指南,了解我们如何为每种材料选择刀片。

我们如何在不赶工的情况下保持短交货期

我们实行两班制,每周工作6天。标准交货期为7天,适用于最多5,000件。对于单个原型件,如果您在中国时间上午10点前确认报价,我们可在3天内发货。我们不赶工——我们只是拥有产能和预调好的常用直径刀具。我们将最常用的夹头和刀片备在货架上,因此无需等待刀具订购。如果您的零件需要定制成型刀具,请增加2天刀具磨削时间。对于大批量订单(超过20,000件),我们转用多主轴机床,单价约下降15%。

此CNC车削服务的最小起订量是多少?

无最小起订量——我们接受单件用于原型制作,并可扩展至每月50,000件。

你们能加工定制形状还是只能加工圆柱形零件?

可以——凭借动力刀具,我们可以铣削六角平面、钻交叉孔和切削键槽,因此您的零件不必是纯圆形。

你们如何确保5,000件批次的质量?

我们每50件进行SPC抽样检验,使用气动量仪对关键直径进行最终100%检查,并随货提供CMM报告。

如果急需零件,最快交货期是多少?

对于长度小于50 mm的简单轴或衬套,我们可在3天内通过DHL快递加工并发货,但这要求您的图纸在中国时间上午10点前到达。

在车床零件上平衡严格公差与合理成本

我们知道您的预算很重要。保持±0.005 mm是我们的标准,但如果您的零件只需要±0.02 mm,我们可以以更快的循环运行,单价约降低8%。Ra 1.6的表面光洁度比Ra 0.4更经济,因为我们跳过了修光刃工序。请始终在图纸上标明关键尺寸——我们不会在不需要的地方过度设计工艺。如果您不确定设计实际需要什么公差,请在发送文件前阅读我们的CNC加工公差指南。这将为您节省成本。

我们是一家中国制造的精密制造公司,但我们不仅仅在价格上竞争——我们在重复性上竞争。我们的回头客每月订购相同零件,他们知道尺寸不会漂移。我们将您的图纸存档,并免费存放您的定制刀具。如果您更改尺寸,我们会更新程序并在批量生产前发送新的首件报告。这就是我们20年来一直让工程师回头的原因。

请以STEP、IGES或PDF格式发送您的图纸。我们的工程师将检查可制造性并在12小时内回复确定报价。报价包括单价、刀具费用(如有)、交货期和运输选项。我们不收取报价费用。如果您需要快速答复,请发送电子邮件至sc@bquq.com或通过WhatsApp联系我们:+86 13713157787。请包含您的目标数量和材料偏好,其余交给我们。无最小起订量,从一个完美零件开始。
