THE COMPANY ALTA AT THE RUSSIAN FEDERATION MARKETThe company Alta has been present at the Russian market for over 20 years. It was one of the very first Czech private com-panies that started to do business in the Russian Federation at the beginning of the 1990s. Throughout the period of our engagement in this territory, we have carefully followed

the market developments, extended our manufacturing base and improved our proprietary engineering expertise. This attitude makes it possible for Alta to con-tinue to win major contracts in the Russian Federation in competition with the leading world manufacturers. In the difficult envi-ronment of the present global economy we

are proud to cultivate the best business re-lationships with the reliable partners in the Russian territory that are so essential for our continued technical development and economic prosperity. That is why the com-pany Alta is a regular participant in one of the major international engineering events - the Metallobrabotka trade fair in Moscow.

We are prepared to extend the portfolio of our customers worldwide; to our traditional business partners, we can offer preferential contract arrangements such as assistance in manufacturing process implementation or know-how transfer.

NEw MEMbER OF THE ŠKODA HORIzONTAL MACHINE FAMILYIn the environment of harsh competition it holds that one of the conditions of busi-ness success is on-going development of new products. Such development must reflect the current market needs and facil-itate widening of the circle of prospective customers.ŠKODA MACHINE TOOL a.s. is proud to continue the more than 100 years old tradi-tion of machine tool manufacturing. Based

on a situational analysis, the company man-agement have decided to extend the prod-uct scope by adding to it a milling and bor-ing machine ŠKODA HCW 1000.The new machine, the smallest in the HCW horizontal machine series, is intended for machining of box-like work pieces of com-plex shapes for power generation, ship-building, mining, chemical, transport and arms manufacturing industries.

The conceptual design of the machine uses a T-layout arrangement with longitudinal turntable travel and traversing column and headstock. The headstock travels vertically along the column and bears extendable spindle of diameter 130 mm. The machine can be installed on a simple workstation foundation. The machine de-sign follows the latest machine-tool con-struction trends with maximum opera-

tor comfort. The HCW 1000 machine has been conceived and built on the basis of the best experience with other machines of the HCW series and other machines and equip-ment bearing the ŠKODA trademark. Upon the customer‘s request, the machine control system SINUMERIK 840D SL sup-plied as a standard accessory can be re-placed by the HEIDENHAIN system.This new member of the ŠKODA horizon-tal machine family will first be presented at the AMB trade fair in Stuttgart, Germany in September 2014.The following table shows the basic param-eters of the HCW 1000 workstation:

SUCCESSFUL MACHINE TAKEOvEROn 15 to 21 February 2014, representati-ves of the Chinese company Henan Diesel Engine Industry Co., Ltd. visited our com-pany. The purpose of their stay with us was acceptance and takeover of the machine FRUFZQ 250B-LR/6. During their stay, the Chinese visitors received training necessary for the machine operation and control.The company Henan Diesel Engine Indust-ry (for short, HND) was founded in 1958 as an affiliate company of China Shipbuilding Industry Corporation (CSIC). Since 1985, CSCI has manufactured products under licence of the German company DEUTZ--MWM. The activities of HND comprise development and manufacture of marine Diesel engines used in commercial, tourist and fishing boats and ships including high--speed and military boats. The biggest HND engines have sixteen cylinders and power output 2,336 kW. HND exports its products to over 50 countries all over the world. The acceptance and takeover of the FRU-FZQ 250B-LR/6 machine at TOS KUŘIM was a smooth procedure and the represen-tatives of the company HENAN DIESEL ENGINE INDUSTRY confirmed the satis-factory condition of the machine intended for their manufacturing operation in the city of Luoyang in China. I would like to take this opportunity and thank all our em-ployees who have participated in the execu-tion of this project. Petr Matula, Sales manager TOS KUŘIM – OS, a.s.

vERTICAL LATHE SKD 40/47 D SUPPLIED TO A MAjOR SLOvAK MANUFACTURER OF HYDROELECTRIC POwER PLANT EqUIPMENTIn January 2014, another vertical lathe ma-nufactured by ČKD BLANSKO-OS, a.s. was supplied to its customer. The machine type was SKD 40/47 D and the customer STM POWER a.s., a supplier of hydroelectric po-wer generation equipment. The final user is one of the suppliers to East Slovakia utility company.The machine functions include turning, mi-lling, drilling, boring and grinding. The lathe facilitates high-precision machining of axial work pieces up to diameter 4,700 mm. The clamping plate is provided with axial pre--stressed hydrostatic seating using a rolling--contact bearing located at the centre of the clamping plate. The guide face of the axial seating on the clamping plate is lined with sliding plastic material. The basic machine parameters are as follows: clamping plate diameter 4,000 mm, the maximum turning diameter 4,700 mm, the maximum work piece height 2,500 mm and the maximum work piece weight 50 t. The horizontal ca-rriage travel length is 2,550 mm (X axis), the slide travel length 2,000 mm (Z axis) and the cross-slide travel length 1,800 mm (W axis). The maximum travel speed along linear axes is 8,000 m/min. The main table drive system includes two Siemens motors of unit power rating 71 kW with the maxi-mum aggregate torque 210 kNm. The mi-lling operations are performed by a milling spindle of power rating 37.7 kW, torque 1,200 Nm and maximum speed 3,000 r.p.m. The machine operation is fully automated including automated tool and tool holder replacement. On the right-hand side of the machine there is a double-disc magazine with 18 positions for axial ISO 50 tools and 6 positions for tool holders. Among the la-the accessories are a fixed milling 90° angle head and grinding equipment parked in pick-up magazines; these accessories can also be used in the automated machine ope-ration mode. Movements in X and Z axes

are controlled by a CNC SINUMERIK 840 D SL system. The travel drive systems include AC servomotors in com-bination with ball screws and pre-stressed pairs of ball nuts. By putting this machine in operation we could include an important project among our references in Slovakia. The customer confirmed that the supply of this vertical lathe would serve as a positive reference for ČKD BLANSKO--OS and their own activities in the Slovak power genera-tion industry.

Shaping and working of various materials is associated with the early stages of human civilisation. The first technologies used by man included drilling and turning. The first written references to a lathe-type of mecha-nism date back to the 3rd century B.C. The invention of propellant powder in Europe and the need for precise machining of gun barrels resulted, in the 14th century, in pro-duction of the first metal-working machi-nes with boring and turning functions.The inventor of modern lathe is believed to be the British engineer Henry Maudslay (1771 – 1831) who also invented shaping machine and micrometer. His lathe facilita-ted both precise turning and thread cutting.

The machine had a cast metal bed and a lead screw controlling the carriage travel at thread cutting. The lead screw rotation was mechanically coupled to the main ma-chine movement - the work piece rotation. Replaceable wheels made possible cutting of threads of various leads.The first milling machine came into being much later - at the beginning of the 19th century, probably in 1818. From the very beginning, it had the same basic parts as contemporary machines. The column was rather low, made of wood and supported by thin cast-iron legs.Milling machines found wider application only after their presentation at the World Exhibition in Paris in 1867. A demonstrati-on of the capabilities of a universal milling machine met with great and well-deserved admiration then.When Škoda Works aspired to find a pro-minent place among the European enginee-ring companies at the end of the 19th centu-ry, it had to include among its already wide

FROM THE MACHINE TOOL MANUFACTURINg HISTORYproduct portfolio including steel castings and forgings, power generation, metallur-gical mining and other machines the arms. At that time the Austro-Hungarian navy and later even the army started to moder-nise their equipment where the demands, in particular regarding heavy guns, were steadily growing. It was a technically cha-llenging task as machine tools facilitating working large and heavy gun parts were not available in either the domestic or the inter-national markets. Here the talented engi-neers and highly qualified shop workers of Škoda Works found an opportunity to de-monstrate their skills. A design group esta-blished in 1911 could present the results of their efforts with surprising speed: a mere one year later, a vertical lathe for turning axial work pieces up to 6,000 mm in diame-ter and weight up to 135 t was manufactu-red, to be followed shortly by a horizontal boring machine with a spindle of a diameter 500 mm and length 8,000 mm, a horizontal milling machine with the spindle diameter 160 mm and a special portable universal horizontal boring machine with the spin-dle diameter 120 mm and an independent electric drive. At the onset of World War I, in production were, apart from various smaller machine tools, high-speed lathes 800x8,000 mm and 800x16,000 mm used

dominated. All these machines were noted for high technical standard, precision and modern design. Nevertheless, they did not prevent dissolution of the Monarchy in 1918. In the new Czechoslovakia, the well--established machine-tool operation started to implement a piece-oriented production with a much wider product scope.This was the beginning of the history of ma-chine tool production at Škoda Works that formed a solid base for future developments and the present-day position of the compa-ny in the realm of heavy machine tool ma-nufacturing.

for gun barrel machining. Intended for the continuously growing arms-manufactu-ring operation were horizontal boring and milling machines of the spindle diameter 140mm. These and other special machines made it possible for Škoda Works to supply complete assortment of guns and associ-ated equipment to the Austro-Hungarian navy and its combat vessels including sub-marines, destroyers, cruisers and large ba-ttleships. A special order concerned guns for a cruiser for Uruguay. Design and ma-nufacture of large machine tools continued throughout WWI when the production of lathes, boring and grinding machines pre-

The company‘s system is based on ILO-OSH 2001 and OHSAS 18001:2007 standards. The audit report con-firmed that both the system control pro-cedures and attitu-des of the company‘s employees meet the requirements of said standards and comply with the expectations associated with a Safe Company.

AMONg THE wORLD‘S ELITEIN HANNOvEROne of the most efficient marketing tools is the company‘s participation in technologi-cal exhibitions and trade fairs where perso-nal contacts with current and prospective business partners provide important feed-back on the customers‘ needs and require-ments.The EMO 2013 trade fair that took place in Hannover, Germany in September was an opportunity to compare the company‘s achievements with those of other world‘s leading heavy tool manufacturers. ŠKODA MACHINE TOOL exhibited its latest ver-sion of HCW 2000 machine that was at the centre of attention of numerous potential customers.This year, the company will present its pro-ducts and activities at trade fairs META-LLOOBRABOTKA in Moscow, IMTS in Chicago, MSV in Brno and, in the autumn, in Stuttgart in Germany, where the latest addition to the company‘s scope of pro-ducts, ŠKODA HCW 1000 will be exhibited for the first time.
