汽車工業(yè)對系統(tǒng)業(yè)務的要求非常高，體現(xiàn)在生產(chǎn)率、靈活性、可用性和過程安全性等多方面，只有通過最高水準的系統(tǒng)專業(yè)技能和流程專業(yè)知識才能滿足這些要求。尤其在過去幾年里，OEM(原始設(shè)備制造商)的預期顯著提高。在缸蓋、曲軸箱和變速箱殼體等工件的加工中，必須在確保安全產(chǎn)出的前提下實現(xiàn)大批量供貨。這要求持續(xù)加大對切削流程的優(yōu)化力度，并且一方面積極采用新技術(shù)，另一方面確保工藝流程安全可靠——將生產(chǎn)成本降到最低。
豐富經(jīng)驗和超高技術(shù)實力
作為一家交鑰匙供應商，格勞博通過配備單主軸或雙主軸的G系列G300/G320、G500/G520、G700/G720 和G800 型號機床確保其 OEM 順利完成大批量生產(chǎn)，同時滿足安全產(chǎn)出和高可用性要求，并符合承諾的周期時間，達到期望品質(zhì)?；陂L期累積的經(jīng)驗和久經(jīng)考驗的工藝流程、技術(shù)和刀具知識，格勞博可以按照格勞博標準、相關(guān)法律法規(guī)和客戶設(shè)計說明書的規(guī)定進行模塊化供貨和組裝。不管是用線性龍門吊車架自動裝載，還是在遵守所有重要安全指令的前提下進行人工裝載，均是如此。因此，自 G 模塊投入使用以來，格勞博已將 10,000 多臺機床銷往全球汽車工業(yè)。在第六代產(chǎn)品的研發(fā)過程中，格勞博再次對 G300 和 G500 機型的單主軸和雙主軸 G 模塊進行了若干個重要優(yōu)化。主要涉及：
· 線性軸和旋轉(zhuǎn)軸的動態(tài)提升;
· 外部尺寸縮小;
· 當作為單主軸和雙主軸 G 模塊時與工藝時間同步的刀具裝載;
· 顯著提升刀具容量和延長最大刀具長度;
· 通過縮短工件與主軸端之間的最小間距使刀具設(shè)計理念更加穩(wěn)定;
· 按手動或自動順序(從前往后或從上往下)在機床上裝載刀具;
· 針對汽車工業(yè)各類材料(從鋁材，鋼材到鑄鐵)的切削需求，開發(fā)出各式電主軸;
· 提供適用于各種材料加工的各類電主軸，比如適用于高性能鋁材切削的轉(zhuǎn)速高達 30,000 min-1 的電主軸，適用于鋼材和鑄鐵加工的扭矩超過 400Nm 并帶 HSK-A100 刀具架的電主軸。
基于 G 模塊的這些優(yōu)化，格勞博已經(jīng)準備就緒，可以服務于全球汽車工業(yè)及其零配件供應商的多樣化高規(guī)格應用。而且十分重要的是：格勞博的模塊化理念使機床在新項目中的再利用成為可能——這是汽車工業(yè)一個非常重要的要求。
為零配件供應工業(yè)提供最佳服務
格勞博是最重要的機床制造商之一，可以設(shè)計并提供從半自動化到全自動化機床的各類完整自動化系統(tǒng)。鑒于當前汽車工業(yè)所面臨的全新挑戰(zhàn)，這種能力正是汽車工業(yè)所急需的，讓我們的客戶即使在未來也能在設(shè)備設(shè)計理念方面保持高度靈活性。除 G 模塊外，格勞博還為對質(zhì)量和產(chǎn)量有著超高要求的高度專業(yè)化訂單提供模塊化專用機床。其模塊化結(jié)構(gòu)由標準加工單元組成，可以與 G 模塊完美組合為混合生產(chǎn)系統(tǒng)?；诰o湊的模塊化構(gòu)造方式，各種作業(yè)精度極高且完全自主的工作單元應運而生。憑借自動化運輸系統(tǒng)，我們能夠提供適用于工件運輸?shù)目蛻魧俳鉀Q方案。格勞博裝載用龍門吊車架和滾道是對系統(tǒng)機床的補充，與其共同構(gòu)成復雜的全自動化生產(chǎn)線。此外，新型軟件技術(shù)的使用使進一步提升生產(chǎn)設(shè)備可用性、生產(chǎn)率和效率成為可能。
GROB-AUTOMOTIVE
Over 90 years of experience in the systems business
Customers in the automotive sector place extremely high demands on productivity, flexibility, availability and process reliability in the systems business. These requirements can only be met with the highest levels of systems expertise and process know-how. The expectations of original equipment manufacturers (OEMs) have increased dramatically, especially in recent years. To ensure work pieces such as cylinder heads and cylinder engine block and transmission housings can be machined reliably in high volumes, machining processes have to be continually developed and new technologies have to be constantly and reliably implemented. All of this takes time and effort and has to be done while keeping production costs as low as possible.
Bundled experience and extensive technology know-how
GROB is a turnkey supplier. Our G300/G320, G500/G520, G700/G720 and G800 G-series models with one and/or two motor spindles guarantee our OEM customers high production volumes, reliable output and high availability in compliance with the agreed operating cycles and requisite quality levels. Thanks to its many years of experience and proven processes, technology and tool know-how, GROB can deliver and assemble modular machines to the GROB standard, in accordance with the regulations and specifications of customers. This applies to automatic loading with linear gantries and also manual loading, while factoring in all relevant safety guidelines.
Since the launch of the G-modules, over 10,000 machines have been sold to the automotive industry. GROB has packed a host of crucial improvements into the sixth development phase of its single- and dual-spindle G300 and G500 G-modules. Highlights here include:
· Increasing the dynamics of the linear and rotary axes;
· Reducing the external dimensions;
· Simultaneous tool loading in single- and dual-spindle G-modules;
· Significant increase in tool capacity and increase in maximum possible tool lengths;
· More stable tool concepts by reducing the minimum distance between the workpiece and the spindle nose;
· Loading work pieces in manual or automatic sequence – from the front or from above;
· Broad spectrum of motor spindles for machining all materials in the automotive industry – from aluminum to steel and cast materials;
· Broad spectrum of motor spindle types for machining different materials. For example, high rpms of up to 30,000rpm for machining high-performance aluminum, and very high torque levels (in excess of 400 Nm) with a holder for an hollow shank taper-A100 tool for machining steel and cast iron materials.
These G-module developments put GROB in the ideal position to meet the varied and exacting application needs of the global automotive industry and its suppliers. Another important aspect – GROB’s modular principle means that machines can be reused in new projects – a crucial requirement for the automotive industry.
Optimum provider for the supplier industry
GROB is one of the few machine tool manufacturers capable of planning and supplying the full range of automation in every form – from partial to full automation. In light of the new challenges facing the automotive sector, this capability is required so that we can continue to offer and supply our customers the highest levels of flexibility for their plant designs in the future. In addition to G-modules, GROB delivers modular special-purpose machines for highly specialized tasks that require the highest quality standards and stringent output requirements. These modular configurations are made up of standardized machining units and can be perfectly combined with G-modules to create hybrid production systems. The compact, modular design enables independent units to be created that work with the utmost precision.
With our automated transport systems, we can offer customer-specific solutions for transporting work pieces. GROB loading gantries and interlinked lines round off the system machines to create a fully automated, complex production line. New software technologies can also be used to further increase the availability, productivityand efficiency of the production systems.
