▽ 请简单介绍下您负责的业务板块。

Please introduce your experience.

 

李双全:stoba Sondermschinen GmbH (斯托巴设备定制)是Stoba集团的一部分。斯托巴集团另有5家斯托巴精密零部件(stoba PRECISION)公司组成,它们位于世界各地,生产高精密金属部件;stoba集团的另一个成员是stoba e-SYSTEM,这是一家更面向未来的公司,开发和制造用于特殊应用的电气驱动系统。

 

Leo Lee :Stoba Sondermaschinen GmbH is part of the stoba Group. The stoba Group consists of 5 companies stoba PRECISION, which are located all around the world to manufacture high precision metallic components. Another member of the stoba Group is stoba e-SYSTEM, a company, which is more future oriented and therefore develops and manufactures electrical drive systems for special applications.

 

stoba Sondermschinen GmbH (英文:stoba CUSTOMIZED Mechanism,(CM))是一家机床制造商,采用电化学金属去除工艺或激光金属去除工艺对金属部件进行加工、去毛刺、结构和表面精整处理。

 

Last but not least, there is the stoba Sondermaschinen GmbH or stoba CUSTOMIZED MACHINERY (CM) which is manufacturer of machine tools where electrochemical metal removal processes or laser metal removal processes are used to machine, deburr, structure and surface finish metal components. 

 

成立后,业务部门stoba CM是stoba精密(PT)的机器和工艺供应商。stoba PT始终与其客户密切合作,开发新的或特殊的工件生产工艺,如用于柴油和汽油喷射的零件,stoba CM向stoba PT提供了工艺技术和相关机器和设备,以高生产率和极高生产率生产这些新零件。待CM设备在PT工厂稳定、高产运行多年后,逐步被其他客户及客户的其他供应商而青睐。

 

After founding, the business unit stoba CM, was machine and process supplier for stoba Precision (PT). stoba PT has always worked closely with their customers in the development of new or special production processes of workpieces as e. g. parts used in Diesel and Gasoline injection, stoba CM has supplied stoba PT with process technologies and related machines and equipment to produce these new parts with high and very high production rates.  After years of stable and high-yield operation in PT plant, CM equipment are gradually be favored by other customers and other suppliers of customers.

 

 

▽ 贵公司的市场份额是多少?核心竞争力是什么?

What is the market share of your company? What is your core competitiveness?

 

李双全电化学加工工艺(ECM)是一种刀具(阴极头)和零件无接触、无应力且加工效率高的去毛刺工艺。该工艺的竞争力在于,可以快速去除工件内部毛刺和实现倒圆角,具有其他工艺无可比拟的精度和经济效率,且可以同时加工多个零部件。

 

Leo Lee :The electrochemical machining processes ECM carry out operations burr-free, cold, with no contact of tool and parts, stressless and fast.The very competitiveness of the process is, that operations can be carried out internally of workpieces fast, with a quality that no other process can provide and economically efficient. The other competitive characteristic is that the machine can process several components simultaneously.

 

ECM工艺能够加工所有导电材质,且不同硬度的材料都能保证相同的加工效果,并且没有常规刀具那样的由于磨损产生的差异。即使是用于飞机发动机或医疗植入物的坚硬材料,在加工时也能保证和其它软材料一样的效果。

 

The ECM-Process is capable to machine all kinds of electrically conductive metals. It removes soft or hardened steel with the same effectiveness and without difference in tool wear. Even tough material as used in aircraft engine business or medical implants can be machined without a difference to soft steel.

 

适用于工件内部的去毛刺工艺-电化学去毛刺,去除工件内部交叉孔边缘的毛刺。电化学去毛刺工艺能够安全、可靠、快速地去除工件上的所有毛刺。这种去毛刺的工艺流程保证了在以后使用工件时,不会有毛刺脱落,也不会有微小毛刺或二次毛刺脱落而造成工件损坏的情况。

 

Manufacturing processes internally of workpieces are -electrochemical deburring, to remove burr at edges of intersecting holes inside the component. The electrochemical deburring process removes safely, reliable and fast all burrs of a workpiece. The process is normally performed in a way that in later use of the workpiece no burr will brake of, no micro-burrs or secondary burrs will brake of and damage the workpiece and component.

 

通过电化学加工工艺倒圆角和成型加工方式使工件成型,是使用ECM成型的下一个步骤。在电化学去毛刺后,去除边缘处的更多材料,以形成工件所需的边缘形状。此外,如需要将该零部件用于液压装置,以达到柴油和汽油喷射所需的非常高的液压压力。在电化学去毛刺的基础上,还需要进行电化学精整处理,以塑造和完成边缘的表面要求。

 

Electrochemical radiusing or chamfering of edges. This is the next step to use ECM to form edges. Following to electrochemical deburring, more material at edges is removed to form the required shape of the edge. Additionally, to electrochemical deburring the electrochemical radiusing process is required to shape and finish the surface of edges as it is required to use the component in hydraulic devices used for very high hydraulic pressure as required in Diesel and Gasoline Injection.

 

电化学成型是一种制造工艺,用于在工件内部加工具有精确几何形状和表面光洁度高的三维空腔。当然,该工艺无毛刺产生。

 

Electrochemical shaping is a manufacturing process to manufacture 3D-Cavities inside of workpieces with precise geometry and finished surfaces. Of course, this process works burr-free.

 

没有任何其他工艺能够达到电化学加工ECM在工件内部加工的质量高度。

 

No other process can machine workpieces internally with the quality as electrochemical machining ECM can do.

 

电化学加工ECM和精密电化学加工PECM。这两种工艺都是通过电化学加工实现三维型腔。

 

Eectrochemical machining ECM and precisely electrochemical machining PECM. Both processes are used to produce 3D shapes electrochemicaly.

 

 

▽ 您的主要产品或服务有哪些特点?你关注哪些领域?

What are the features of your major products or services? Which areas do you focus on?

 

李双全对于我们的客户来说,ECM工艺流程有时很难把控。为了帮助我们客户解决这一难题,斯托巴设备定制团队开发了全自动化的电化学ECM设备,客户只需要把加工的工件放进去,全自动化设备会自动完成加工、清洗、防锈和干燥的工序,客户只需等待取出加工完的工件即可。

 

Leo Lee :For our customers the ECM process is sometime difficult to handle. In order to assist our customers, stoba CM has developed fully automized machines cells where the customer can feed raw workpieces in and take machined, cleaned, rust protected and dried workpieces out.

 

斯托巴设备定制团队可以根据客户要求设计和制造自动化操作系统,所有工艺工序如预清洗、ECM去毛刺、后清洗、钝化和干燥工序均可自动完成。

 

All process steps as e. g. pre-cleaning process, ECM process, post cleaning process, passivation process and drying process are operated by the automation system, designed and manufactured by stoba CM according to customer’s requirements.

 

贵公司的运营模式是什么?与其他运营模式有何区别?现在的运作如何?

What is your company’s operation model? What distinguishes your model from others’? How is it operating now?

 

李双全为我们客户提供专业定制的业务已经让斯托巴形成了灵活的业务单元,如果终端客户急需零件,我们斯托巴零部件生产团队就会及时响应提供产方案设计和品代工服务。

 

Leo Lee :Special business of our customers has formed all stoba business units to very flexible units. If end customers need parts quickly, our colleagues from stoba PT have to act quickly as well.

 

如果客户需要改造或升级设备或夹具,斯托巴设备定制团队也随时待命提供设计、制造和安装的方案并准备所需的备件。所有斯托巴业务单元相互合作密切,并在其日常业务中与其他业务单元分享经验。这种“常年累月积累下来的经验”被永久地引入到设备制造和工艺改进中。所有客户都可以确信,每台离开斯托巴设备定制工厂的设备和工艺都集成了最新的技术和知识。

 

If it is required to modify their machines or fixtures stoba CM is ready to design, manufacture and install required modifications of machines and fixture. All stoba business units work closely together and share experience over a long time with other units in their daily business. This “long-time-experience” is permanently introduced to machines and processes, which are ready to be sold to other customers. All customers can be sure that each machine and process, that leaves the factory of stoba CM has latest technology and know-how integrated.

 

特别是如果ECM设备或ECM工艺用于高产量需求的情况下,斯托巴长期积累的经验使设备和工艺更可靠。目前为止,这仍属于斯托巴独一无二的优势。

 

Especially if the ECM machine or ECM process is used in very high production cases long-time-experience makes machine and process robust and reliable. There is no other company on the market which has the same opportunities as companies of the stoba Group.

 

▽ 随着现代工业的发展和需求的不断提高,市场上的应用需求出现了哪些变化?客户希望改进和升级哪些方面?我们如何处理它?

With the development of modern industry and continuously improving requirements, what changes in application requirements are emerging in the market? Which aspect do clients want to improve and upgrade? How do we deal with it?

 

李双全由于斯托巴集团的主要业务是提供用于燃油驱动系统的零部件,因此,向电力驱动系统的转变是斯托巴集团面临的挑战之一。然而,早在几年之前,斯托巴就已经开始为这一转变做准备。在斯托巴集团的指导下,stoba e-Systems成立了,并已向汽车行业以外的客户提供工艺和设备的解决方案。例如飞机、医疗、民用等行业。

 

Leo Lee :Since the main business of the stoba Group is to provide components used in combustion drive systems, this future change to electric drive systems is one of the challenges of the stoba Group. However, already years ago stoba has started to prepare for the change. Under the guidance of the stoba Group stoba e-Systems was founded, other markets have be approached e. g. aircraft, medical, civil etc. and machines with process solutions have been supplied to customers outside of the automotive industries.

 

斯托巴集团也在努力保住约1100名主要从事燃油机相关生产的员工的工作岗位。为了保住他们的工作,斯托巴已经积极调研了其他具有类似要求和特点的应用。从中我们发现了在飞机发动机业务、医疗植入物、民用工业等方面相似应用的市场。此外,除了电气驱动系统外,其他驱动系统(如氢驱动系统)仍在开发中,斯托巴有很好的机会利用设备和工艺技术服务于该市场。

 

Goal of the stoba Group is also to protect jobs of about 1.100 employees who work mostly in the production of combustion powered engines? In order to protect their job stoba has proactively investigated other applications, which have similar requirements and characteristics. Here we found applications in aircraft engine business, medical implants, civil industries etc. Additionally the fact that beside electrical drive systems other drive systems as e.g. hydrogen drive systems are still in development stoba has good opportunities to serve this market with machines and process technology.

 

 

▽ 疫情是如何影响和改变国内外产业链的,从突然爆发到今天的标准化预防和控制?

How has the pandemic impacted and changed the industrial chain both at home and abroad from the sudden outbreak to today’s standardized prevention and control?

 

李双全疫情对斯托巴业务的影响很大。所有客户立即开启保守的采购模式。一方面,我们刚刚进军的大型飞机项目由于需求降低而与订单失之交臂;但是从另一方面来讲,这也给我们带来了进军新市场的机遇和精力。另外的一个影响是交付时间。所有次级供应商都增加了交货时间。特别是那些与电子芯片行业相关的项目,通常由中国制造商提供的产品。这些最终都会影响斯托巴的交付时间。

 

Leo Lee :The pandemic impact to stoba’s business is strong. All customers started immediately to purchase more conservatively. Projects for large aircrafts, which were very close to be purchased broke away on one side. On the other side we were able to enter new markets and compensate that what broke away. The next challenge is now to delivery time. All sub-suppliers increased delivery time. Especially for those items which are related to electronic chips industries and normally are delivered from Chinese manufacturers.

 

▽ 目前的行业痛点是什么?什么是新的机会?未来的核心竞争力是什么?

What is the industry pain point today? What are new opportunities? What is the core competitiveness in the future?

 

李双全交付时间。受疫情的影响,全球各行各业都受到了影响,特别原材料采购的交付延长。

 

Leo Lee :Delivery time. The pandemic has shown everybody that global industry has to be questioned. Especially the raw material purchased under the long delivery condition.

 

▽ 贵公司是否正在研究和开发新技术或新项目?贵公司未来的战略和目标是什么?

Are your company researching and developing new technology or new project? What is your company’s future strategy and goal?

 

李双全斯托巴集团和斯托巴的每个业务单元一直都致力于开发和研究新项目。但目前尚处于保密阶段。

 

Leo Lee :The stoba Group and every business unit of stoba works on development and research. This however, is information that should not be disclosed now.

 

▽ 请用一句话分享你对中国制造业未来的期望

Please share your expectation of the future of Chinese manufacturing industry with one sentence.

 

李双全在中国开展业务需要很长时间的蛰伏准备才能取得成功,但是,如果你有足够的能力熬过这个阶段,你会发现中国的市场很开放、潜力很巨大。

 

Leo Lee :It takes long time after starting business in China to get successful, however, if you have the breath to survive the ramp-up phase you will find open minded Chinese customers and huge markets.
