德国HWR精密工装夹具实际应用案例 |格劳博机床引入INOFlex®卡盘与INOZet®桥摆，显著提升生产精度与效率

格劳博机床将INOFlex引入其生产中

GROB-WERKE公司总部位于明德海姆，是一家世代传承家族文化的全球性企业。公司全球拥有5300名员工，产品包括通用机械、复杂制造系统、装配系统等。对于客户而言，格劳博的机床和系统解决方案代表着精确度和可靠性的标准。

为了确保其领先地位，格劳博强调不断改进自身的生产。近年来，格劳博将【INOLine】工件夹具融入到生产中。

Frühschütz先生是负责工具管理的格劳博团队成员，他最初是通过Atos GmbH公司了解到[INOLine]的，该公司是HWR的金属加工解决方案供应商。Atos最初向Frühschütz先生介绍了INOFlex®卡盘的信息，以及这些产品如何提高格劳博的生产效率。 

一旦他被说服，Frühschütz 先生就与 Atos 的 Schmalz 先生和 HWR 的 Maniscalco 先生一起为采用 INOFlex® 开发商业案例。这个三人团队共同向格劳博的采购决策者证明，带有中心夹紧功能的 INOFlex® 补偿卡盘可以提供与三爪卡盘一样的抓取力，而且精度更高。

在 Maniscalco 先生向由 15 名格劳博员工组成的团队演示之后，该公司决定购买一个 500 毫米 INOFlex® 卡盘和一个 INOZet® 桥摆。

通过 INOZet® 桥摆，INOFlex® 4 爪卡盘可变为补偿摆动式 8 爪卡盘。这一解决方案 “超越 ”了广泛使用的 6 爪卡盘。

采用新解决方案后，格劳博选择了一个零件来测试其能力。该部件生产成本和测试很昂贵，到目前为止，同心度仅为 0.3 mm。格劳博工头 Schaufel 先生参与了该项目，并负责监测和记录结果。在 INOFlex® 和 INOZet® 的共同作用下，同心度降低到了 0.02 mm。

“我们对 INOFlex® 卡盘非常满意，"Schaufel 先生说。“我们直接节省了昂贵的打磨费用。此外，这种卡盘几乎不需要任何维护，因为即使在涉及铸件加工时，它的密封性也非常好"。

从第一天起，新系统就为格劳博节省了生产成本。

“Frühschütz先生说："我们将继续沿着这条道路前进，更多的INOFlex®卡盘将被集成到Grob的生产中。

GROB Werkzeugmaschinen introduces INOFlex® into its production

Headquartered in Mindelheim, GROB-WERKE is a global company with a family culture that has been deeply anchored for generations. Employing 5,300 employees worldwide, the company’s portfolio includes universal machines, complex manufacturing systems, assembly systems and more. To its customers, GROB’s machines and systems solutions represent a standard for precision and reliability.

To retain its premiere position,  GROB emphasizes constant improvement across its own production. In recent years, these efforts have included the integration of [INOLine] workholding into its operations.

Mr. Frühschütz, the GROB team member responsible for tool management, was initially introduced to [INOLine] via Atos GmbH, a supplier of metal processing solutions that represents HWR. Atos initially presented Mr. Frühschütz with information INOFlex® chucks and how these products could enhance GROB’s production.

Once he was convinced, Mr. Frühschütz worked together with Mr. Schmalz of Atos and Mr. Maniscalco of HWR to develop the business case for adopting INOFlex®. This team of three worked together to demonstrate to GROB’s purchasing decision makers that the INOFlex® compensating chuck with centrical clamping could provide just as much gripping power as a 3-jaw chuck and with greater precision.

Following a demonstration by Mr. Maniscalco to a team of 15 GROB employees, the company decided to acquire a 500 mm INOFlex® chuck and an INOZet® pendulum bridge.

Through the INOZet® pendulum bridge, the INOFlex® 4-jaw chuck can be transformed into  a compensating pendulum 8-jaw chuck. This solution has “overtaken” the widely used 6-jaw chuck.

Upon adoption of the new solution, GROB selected a part to test its capabilities. The component required a considerable outlay and, up to that point, was achieving concentricity of 0.3 mm. Mr. Schaufel, a GROB foreman, worked on the project and took responsibility for monitoring and documenting the results. With the combination of INOFlex® and INOZet®, concentricity was reduced to just 0.02 mm.

“We are delighted with the INOFlex® chuck,” said Mr. Schaufel. “We economized on expensive sanding-down straight away. Furthermore, this chuck requires hardly any maintenance, as it is excellently sealed even when cast machining is involved.”

From day one, the new systems provided GROB with cost savings in its production.

“We will continue down this path, and more INOFlex® chucks will be integrated into Grob’s production”, said Mr. Frühschütz, who looks forward to continuing to work together with both Atos and HWR.
