The machine accessories reflected in the sales of ŠKODA machine tools to the accident in Japan earlier this year has affected the make also possible efficient slotting of generator rotor manufacturers of the windmill power unit component ŠKODA SR 2, Holland global position and prospects of nuclear power generation. The interest in renewable power sources such as wind has been revived. Construction of new water power plants using river gradients, representing the third largest power source, is strictly limited by natural conditions. We may say that progress depends on sufficient energy capacities. In many countries today, lack of energy shafts. Machining of the longitudinal slots to accommodate the excitation winding is done by special disk milling tools clamped either in a milling head or directly in the machine spindle. The company ŠKODA POWER makes advantage of the high operational efficiency and precision of a ŠKODA HCW 3 machine equipped with a TDV 8 turntable in machining turbine casings. The company owner, the parts. Lathes ŠKODA SR 2 have been supplied to the Dutch company AMERSFOORT; ŠKODA lathes are also used for machining of windmill power unit parts at the company PILSEN STEEL. The growing global power requirements and the corresponding boom in the power equipment generation industry are going to be a great business opportunity for heavy machine tools bearing the trademark of ŠKODA. actually curbs the economic and social developments. It therefore appears that large-scale construction of new power sources is inevitable. And indeed, manufacturers of power generating equipment have lately been ŠKODA HCW TDV 7 BRUSH, Czech Republic receiving steadily growing numbers of orders. To increase efficiency of high-output power units, it is required to provide for high precision of the power equipment part machining operations. The key aspects in this respect are high rigidity of the machine, tool and part combination and temperature stability of the machine tool concerned. The company ŠKODA MACHINE TOOL a.s. is a traditional manufacturer of heavy machine tools marketed under the ŠKODA trademark. During the past 15 years it supplied more than 26% of its production to the power generation equipment manufacturers where this share tends to further grow. Among our customers is the company BRUSH SEM s.r.o. in Plzeň, part of the BRUSH TURBOGENERATORS division, the biggest manufacturer of large power generators worldwide. This company uses a horizontal machine ŠKODA HCW 3 with spindle diameter 200mm in combination with turntable ŠKODA TDV 7 with a clamping plate of dimensions 4,000 x 5,000mm for work pieces up to 95t and other technological accessories.

2 MODERNISATION OF ŠKODA MACHINE TOOLS ŠKODA W200HA - HCW3 + TDV 5, Russia At the company ŠKODA MACHINE TOOL a.s., execution of a business contract is understood to be commencement of a long-term close relationship with the customer. Such relationship implies on-going improvements in reliability and efficiency of earlier manufactured machines through major overhauls and modernisation projects. Since 1990, supplied to our customers have been altogether 507 heavy machine tools: horizontal milling and boring machines and heavy centre lathes. The tradition of successful projects and the good image of the ŠKODA trademark are the company s cornerstones. The growing demands concerning technological standards and labour efficiency result in demands for modernisation of older machines and bring interesting contracts to the company. ŠKODA MACHINE TOOL (ŠMT) offers execution of modernisation projects tailored to the customer needs. The technological capabilities of machine tools can be extended through delivery of new headstocks and modern accessories such as automated tool-changing equipment, milling and boring heads, chip conveyors, clamping plates and turntables for horizontal machines, and automated turrets, plate slide rests, grinding and milling equipment and tool and work-piece control devices for lathes. In a typical arrangement, the machine dismantling, upgrading and commissioning are performed by ŠMT experts at the customer s plant. The machine foundations can usually be left as they are. Following major overhauling and modernisation, the machines meet the EU (CE) requirements or other relevant technical standards in non-eu countries (UL, CSA and others). The modernised machines are subject to the same warranty conditions as any new machine. Every product will need, sooner or later, some maintenance and repairs. The manufacturing company stays in contact with its customers in order to obtain immediate and unbiased assessment of its products. In this way, the customer indirectly participates in development of new products. The latest development results are then applied in major overhauls and modernisation of older machine tools. The company also offers to its customers dedicated personal care of the purchased machines in the form of preventive examinations, provisions of services and spare-part deliveries. These services require a quality manufacturing base and teams of skilled experts. The company is known to possess excellent research, development and design capacities. Since May 1998, the company has had the ISO 9001 quality system certificate. The new orders for machine modernisation projects testify to the fact that these services are in demand. In this year alone, seven major contracts worth over CZK 200 million have been signed. Thus overhauling and modernisation have become an important complement of the machine-tool manufacturing line at the company ŠKODA MACHINE TOOL a.s. The growing demand for the company products and services in the first half of 2011 is indicative of economic revival in various territories and is a hopeful sign of future economic growth of the company. ŠKODA W250HC + TDV 7, Ukraine Heavy machine tools from ŠKODA MACHINE TOOL are successfully used in production of windmill power unit components The growing interest in renewable power sources brings new business opportunities to the company ŠKODA MACHINE TOOL in supplies of horizontal machines and lathes to the manufacturers of windmill power unit component parts. Regarding horizontal milling and boring machines, the manufacturers of windmill power unit components purchase modern modular machines of the HCW type series in various sizes. So far, orders have been received for horizontal machines of the HCW 1, HCW 2 and HCW 3 models. These highly sophisticated machines are characterised by outstanding parameters concerning machining power, speed and torque, as well as working precision, operator comfort and safety of the complete horizontal workstation. Supplied with the machines can be a wide range of accessories including turntables or milling and boring heads that find advantageous application in manufacturing of the windmill power unit component parts. Some of the machines are supplied in configurations tailor-made to the needs of the manufacturers of one or more specific components. Regarding lathes, the manufacturers of windmill power unit components have ordered several machines A small front (T-shaped) shaft worked on ŠKODA SR 2 lathe, Holland ŠKODA HCW 1, Germany SR 2 of the modern modular SR type series; another machine of the SR 3 size in currently in production. The ŠKODA lathes are noted for high-level performance, working precision, easy control and high operational safety. Among the technological accessories available from the machine manufacturer is a milling tower of rated power 37kW. In the milling tower configuration, a single machine can perform turning, milling and boring operations and so ensure high operational efficiency. More detailed information on all ŠKODA HCW and SR machines can be found on web site It is important to add that the above machines were delivered in turns where apparently new orders by the windmill power unit component manufacturers were placed based on good experience with earlier delivered machines. And new orders continue to arrive. The management of the company ŠKODA MACHINE TOOL believe that the present boom in the windmill power business and the good references of the ŠKODA machine tools delivered to this market segment will open up new opportunities for sales of the company horizontal machines and lathes to the manufacturers of windmill power unit component parts.

3 COMING OF THE GIANTS ŠKODA HCW 3 The market trends towards high performance and efficiency with lower energy requirements and the maximum effectiveness of manufacturing processes generally lead to the construction of ever larger products and equipment. Examples of such achievements are numerous. The largest gas turbine recently put in trial operation in Bavaria weighs 444 tons and its output power is 530MW. The largest windmill turbine with a threeblade propeller of diameter 126m works 126m above the sea level and can generate up to 7MW of electric energy. The biggest tanker in the world TI OCEANIA is a real giant 380m long with a propeller of 12m in diameter. It was built in the Daevoo shipyards in Okpo in South Korea. The biggest excavators manufactured by ThyssenKrupp are over 200m long and 100m high. The trend towards large products is also becoming evident in the growing demand for heavy horizontal milling and boring machines of the ŠKODA HCW type. For example, this year Chinese customers ordered the following machines: HCW 3 with spindle diameter 260 mm travel in X = 22 m and Y = 8 m, and a turntable with loading capacity of 160 t; HCW 4 with spindle diameter 260 mm travel in X = 26 m and Y = 8 m, and a turntable with loading capacity of 160 t; HCW 3 with spindle diameter 200 mm travel in X = 25 m and Y = 5 m, and a turntable with loading capacity of 100 t; HCW 3 with spindle diameter 200 mm travel in X = 25 m and Y = 5 m, and a turntable with loading capacity of 100 t. In production for an Indian customer is the machine: HCW 3 with spindle diameter 250 mm travel in X = 16 m and Y = 6 m, and a turntable with loading capacity of 100 t. A Polish customer has ordered the machine HCW 2 with spindle diameter 180 mm travel in X = 12.5 m and Y = 5 m, and a turntable with loading capacity of 20 t.

In 2010 the company decided to extend the capacity and technological facilities of their own production in order to reduce the manufacturing cost, save the time and eliminate the need for external cooperation on certain more complex components. The main and essential idea was the implementation of the new technology of the progressive five-axis machining of complex components such as impeller wheels of Francis, Pelton and Kaplan turbines and their components. The concept of the floor type machining centre FU V/8 made by TOS KUŘIM includes the rotary table type CES of dimensions 2,000 x 2,500 mm (table feed V = 1,250 mm) primarily for machining of rotary parts and the plate clamping field of dimensions 3,440 x 7,040 mm for clamping of larger components, have proven optimal for the specified needs of the customer. The machine is equipped with the Heidenhain itnc 530 control system, vertical travel is 3,000 mm and its versatility in conjunction with high productivity is guaranteed by the use of automatic interchangeable milling heads VA1 (short roughing), VP2 (angular roughing) and VK (two axis universal) made by TOS KUŘIM. Machining of turbines for large hydroelectric plants Another Czech company ŽĎAS, a.s. uses the gantry type machining centre made by TOS KUŘIM to machine monumental castings of Kaplan s turbine vanes. Individual roughed castings weigh almost 20 tons, are made of stainless steel and are machined for the manufacturer of water turbines from Argentina. The proposed gantry type machining centre FRF V/A6 with the output of 37 kw guarantees sufficient Example of Kaplan turbine machining 1,250 mm) were designed to increase the clearance under the gantry and the workstation was equipped with a special Pick-up tool magazine. The potential of the machine is significantly increased by the use of the automatic interchangeable milling heads VP2 (angular roughing) and VK (two axis universal) made by TOS KUŘIM. Based on the operating experience and with respect to the production start-up curve, the customer - in order to optimize the technological processes of machining - asked the standard head portfolio to be extended to include additional heads type VA1 (straight roughing) and VP1 (angular). The entire installation was completed in the course of 2009 as a turn-key project including the construction of the machine base. The machined vanes are designed for a hydroelectric power plant that is being constructed on one of the many tributaries of the Orinoco River in Venezuela. In order to fulfill the deadlines set by the final customer, another machining center type FRUF C, also by TOS KUŘIM, was included in the process of machining of the turbines. This is the latest type of the milling machine with output of 71 kw, workplace 4,500 x 17,000 mm and clearance between table and cross-rail of changeable milling heads (including head VK-B for fiveaxis machining) by TOS KUŘIM, RENISHAW probe type RMP60 for measuring the workpiece and a device Renishaw NC4 for setting and control of cutting tools. The customer OAO Ťjažmaš specializes in manufacturing of products for the mining industry and equipment for thermal, hydroelectric and nuclear power plants, also supplies equipment for cosmodromes. The blades of turbines for hydroelectric plants will be machined on the machine FRUNQ 300 B - VR/10. Turbine for middle size and large hydroelectric plants

4 Railway industry machined these undercarriages using the current technologies on less productive machines and also had to use outsourcing, which was often very problematic with respect to the required quality and delivery deadlines. In addition to the VO automatically interchangeable universal head (Mk 1,200 Nm), the supply of the gantry-type machining center included a special VP13 automatic interchangeable head of angular design which enables the machining of inaccessible locations without the need of re-clamping and subsequent realigning of a workpiece. Compared to the original technology, TOS Kuřim solution has increased the efficiency of machining by approx. 40%, compared to the existing technological procedure. For machining of undercarriage on the FRFQ 300 VR/A8 machine was used a quite different approach for solving the problem of the sequence of technological operations that had been used on the existing machines so far. By using the productive VO head quite sizable savings were achieved. This head enables machining in horizontal, vertical and angular position of the spindle; the head dimensions allowed for machining of majority of surfaces on the under- Bogie wheel machining Bogie frame casting machining in Czech company ČKD Kutná Hora, a.s. Gantry type machining centre FRFQ 300 VR/ A16 with divided working area and technology for machining of cast steel of bogie frames was delivered to the ČKD Kutná Hora a.s. company in Automatically interchangeable milling heads which were a part of this supply (straight head VA1 - Mk 2,000 Nm, VA2 - Mk 1,000 Nm and angular head VP2 - Mk 1,000 Nm) make the machine suitable for machining of very sophisticated steel castings with a high content of sand and inclusions. Original old solution, which ČKD Kutná Hora was using, was found as not competitive any more. Complete cycle time (roughing + finishing) at the beginning of process of technology debugging in TOS KUŘIM was 162 hours. After a detail revision of the whole technological process of machining including cutting the idle time Wagon undercarriages carriage using full stroke in all machine axes. When machining with the VO head, the following operations were used: plane milling, profile milling, drilling, accurate drilling and counter boring. Delivery of gantry type machining centre to Bombardier Transportation Czech Republic a.s., Česká Lípa Based on a competitive tendering, even in this case TOS KUŘIM became supplier of the FRFQ 300 VR/A10 gantry type machining centre with motor output of 30 kw and divided working area, which has substituted the need for outsourcing of the component machining. This centre also enabled the launch of the production of new types of wagon undercarriages. Delivery of the gantry type machining centre with automatically interchangeable heads for 5-axes machining (type VK - Mk 1,000 Nm and a special angular head type VP10) took place in November The divided working area enables to minimize machine downtime as a result of aligning of further work pieces, and/or cleaning and measuring. down, modifications of clamping elements and above all using of progressive tools, the total time (roughing and finishing) have been reduced to 18 hours and 36 minutes. The final result of this project proved the necessity of careful preparation and gradual testing of partial steps in fine-tuning of technology of similarly sophisticated machine units. Customer s satisfaction is at the end of this arduous process. Machining of tram unit undercarriages in ŠKODA TRANSPORTATION a.s., Plzeň, Czech Republic In 2009, the FRFQ 300 VR/A8 gantry type machining centre was put into operation in ŠKODA TRANSPORTATION a.s., Plzeň, with the power output at the spindle of 37 kw, including a debugged technology for machining of tram unit undercarriages. Until this time, ŠKODA TRANSPORTATION Tram unit undercarriages TOS KUŘIM machines in aerospace industry Since 2002 the gantry type machining centre with movable portal has been working in the important British company. The machine is used for machining of jet engines parts (fan cases). In the years TOS KUŘIM delivered several machines to the Russian company VSMPO, which supplies workpieces into the aerospace industry. Airbus landing gears, for example, have been surfaced on these machines. Companies IAZ Irkutsk Aviation Plant and Hydromash Nizhny are other Russian companies, which have experience with the machining of titanium parts for the aerospace industry on the TOS KUŘIM machines. Two highly productive and dynamic CNC machine tools for contouring were delivered to an important Canadian company at the end of The technology was adjusted for landing gear machining for Machining of engines FAN CASES Boeing airplanes. Forging (original weight of 400 kg) weighted after the final processing only 150 kg, which proves that the machine has fulfilled all the prescribed customer requirements for high-speed machining in the aerospace industry. Last year two contracts for gantry type machines were signed with big Chinese companies supplying the aircraft industry AVIC Xi an Aircraft is a supplier of passenger planes and the TOS KUŘIM center will be designed for machining of titanium and steel sections. Airplane engines will be machined in the company Xi an Aero-Engine. The unique gantry type machining centre FRUNZQ 150-VS /5 was made for this customer. The machine performs standard operations such as milling, drilling, reaming and threading to combine with grinding. High quality of finish surface can be made on one machine up to

5 Grinding on the machine FRUNZQ 150-VS/5 roughness of Ra = 0.4, which brings a clear technological advantage. The machine is equipped in addition by a range of special accessories such are roller for dressing of grinding wheels, tool measure- ment probe, interchangeable head with electrospindle, straight head adapted for grinding function, special software, etc., to enhance machining features. Landing gear machining MULTIPURPOSE MACHINING CENTRES - NEW PRODUCT AT TOS KUŘIM PROGRAM The first signs of the market demanding the multipurpose machining centers began to show at the end of Customers idea was based on an integrated workplace - a part of a horizontal or a portal machining center - complying with the criteria of maximum versatility - which means in addition to milling and boring operations, the center should also enable turning operations. An optimum choice seems to be a machine with CNC rotary table with milling and turning (VTL) functions. Heavy built CNC rotary table with VTL function and auxiliary slide TOS KUŘIM - OS, a.s., a traditional machinery manufacturer, a member of ALTA group, responded to the market demands and in cooperation with the Faculty of Mechanical Engineering of Prague University - ČVUT, the development of a heavy movable CNC rotary table with VTL function has been started. The project is supported by Ministry of Trade and Industry of the Czech Republic as part of the department program of applied research and development called TIP The purpose of the project is to develop a workplace with the table clamping surface area of 3,000 x 3,000 mm, table travel of 1,500 mm, maximum loading capacity of 60 tons and adjustable rotation speed up to 80 RPM and 60,000 Nm maximum torque of rotation. The clamping surface will enable to mount a carousel plate with diameter of 3,000 or 3,700 mm. The turning operations will be performed by turning tools fastened in a special Capto tool holders, integrated with IZN lathe tool holders. The entire turning system will be clamped to the face of the headstock (instead of a particular milling head) and it will enable to storage in the pick-up magazine any time is needed to continue a standard milling operations, using exchangeable spindle head or quill. The table then operates as a standard rotary table. Significant demand for similar multi-purpose workplaces is expected especially in the area of power engineering, specifically the machining of windmill components. Before the heavy CNC VTL table project was started, TOS KUŘIM - OS has delivered to the end user solution of Gantry-type machining center FRFQ 250 Gantry type machining centre with additional turning table - VR/A8 with rotary turning table model TRT 500. The machine is also equipped by a TOS KUŘIM VO automatic exchangeable universal spindle head, operating at 16-5,000 RPMs at max torque of 1,000 Nm. The main machine table dimensions are 2,500 x 8,000 mm where the additional turning table TRT 500 with diameter of 1,000 mm, max speed 500 RPMs and maximum loading capacity of 4,000 kg is placed. The TRT 500 table can be used for vertical as well as horizontal axis operation. The solution increased significantly number and portfolio of the offered machining services at the end user, Czech company Farmet. Illustrative photo

6 SKD 40/47 for ALLARD EUROPE NV of Belgium On 30 June 2011, following almost a full year s effort, the customer ALLARD EUROPE NV of Belgium accepted a second machine tool manufactured by ČKD BLANSKO this time the time-tested model SKD 40/47 D. This two-column vertical lathe with integrated C axis, clamping table of diameter 4,000mm and a milling spindle can work at speeds up to 100 r.p.m. Another machine of this type will follow shortly to be delivered to the Russian Tiazhmach Syzranj. It will probably be the last machine manufactured in the old factory premises in Blansko because all other machines will be assembled at the new hall of the affiliated company TOS KUŘIM OS, a.s. Model SKD 40/47 ranks among the most successful machines manufactured by ČKD BLANSKO throughout its long history and delivered to customers in countries such as Germany, China, Brazil, Russia or the Ukraine. In Czech Republic, the last machine of this type was manufactured for ŽĎAS, a.s. in The machine has undergone several mod- ernisation stages where the last one included a new solution for the C-axis drive using master-slave pinion wheels driving the toothed rim on the machine table and the compact motor-spindle combination incorporated in the front part of the machine slide. The development team at ČKD BLANSKO continue their work on modifications and upgrading of their machine designs so that these would meet most demanding requirements and follow the latest trends in vertical lathes. Such modifications consist of integrated hydrostatic slide-ways in axes X and Z, increased machining diameter (up to 10m with two-column machines) and, as the latest popular feature, Y-axis integration with travelling table or carousel. It should be noted that meeting the ambitious machine modernisation plans will be easier in co-operation with other ALTA Group member companies where it is expected that the new machines will include more modular parts designed by the development teams of ŠKODA MACHINE TOOL, TOS KUŘIM and ČKD BLANSKO. SKD 40/47 D (Allard) Important reference for power generation industry Among the vertical lathes manufactured by ČKD BLANSKO and installed at the customer plants in 2010 is one rather exceptional machine: SKD 63/70 D, the biggest two-column vertical lathe ever installed by the company. Exceptional is not only the machine size, but also the customer LMZ Leningradskyi Metalicheskyi Zavod of the OAO Silovie machiny group ( in the Russian Federation. LMZ is the biggest manufacturer of turbines and other power generation equipment in Russia. The company history dates back to 1857 and, in 2005, it ranked 5th on the list of companies with the largest installed power in the world after the renowned names such as Siemens, GE or Alstom. In any case, a machine delivered to such company makes up a first-class reference in both the Russian and world market and the engineers in Blansko can be proud of this achievement. The SKD 63/70 D machine is based on the wellproven concept of two-column lathes with a table of diameter 6,300mm, maximum work-piece diameter 7,000mm and work-piece weight up to 120t. The SKD 63/70 D (LMZ) table drive of the master-slave type has the rated power of 140kW. The machine includes a single carriage with a slide of 400 x 400mm with a built-in motor and spindle combination of rated power 37kW. The machine is intended for turning and milling operations. Immediately after commissioning, the machine started to be used in 3-shift operation in a machining workshop where it is working to its full capacity. In LMZ, the ČKD machine is the second largest vertical lathe and the operators are satisfied with its performance. In production at ČKD BLANSKO presently is another SKD 63/70 D machine intended for a Czech customer where it should be put in operation in the second half of As mentioned elsewhere in this brochure, the 7-metre vertical lathes are not the ultimate solutions at ČKD Blansko; development work is in progress on machines capable of handling work pieces up to 10m in diameter. In that respect, the machine delivered to LMZ can be seen as the first step in the realm of extra-large vertical lathes. Milling Turning SKD 63/70 D (LMZ) Grinding Printing DRAKON dům reklamy s.r.o.
