ABOUT THE COMPANY


FERMAT PRODUCTION PLANTS CZECH REPUBLIC


EXPANDING FERMAT COMPANY FERMAT MACHINE TOOL LTD

FERMAT Company is a renowned Czech manufacturer of machine tools focusing on Grinding machines and Horizontal Boring and Milling machines. The history of the oldest FERMAT member dates back to 1901. Thanks to this tradition as well as continuous dynamic development of the group which is built on essential business principles such as promptness, fl exibility, excellent customer support, productivity growth, investment in new resources and development of new technologies, FERMAT Company

belongs among dominant Machine Tool Manufacturers in the European and the worldwide market. Today, FERMAT’s annual production is over 100 machines. Wide production, experienced engineers and technicians allow FERMAT to guarantee supplies of grinding machines according to our customer’s needs with fast delivery and reliable service. Technical support involves upgrading of grinders and horizontal boring and milling machines, machining technology solutions and cooperative production,

including heat treatment of parts and supply of castings. Logistic services and fi nance arrangement services form an integral part of the group’s comprehensive care for the customer. FERMAT’s constantly growing and increasing its market share and participates at main International Fairs around the world. Flexibility and innovation is our guarantee for future success.

FERMAT occupies 33 200 m2 (357 362 sq ft) production and assembly halls. The most important centers are situated in Prague and Brno (Prague 5 300 m2 / 57 049 sq ft, Brno 4 800 m2

/ 51 667 sq ft + 3 600 m2 / 38 750 sq ft + 3 700 m2 / 39 826 sq ft). The company sales soared despite the recent economic crisis. In the same period FERMAT acquired several traditional

manufacturers like Pressl Company in Pilsen and Strojtos Llipnik to increase the production facilities.

BrnoBrno

Services covering supply, upgrading and overhaul of the grinding machines within the framework of the group have been provided since 2007 by FERMAT Machine Tool Ltd. located in the heart of Europe, in Prague. After a long-term cooperation with ZeVo Praha Ltd Co., FERMAT Machine Tool Company Ltd is 100% shareholder of that company, which is today a traditional supplier of grinders having been operating continuously in machine upgrading since 1992. Merging of a strong group of experi-enced and high quality production sta-

ff and a well-developed sales system of FERMAT group led to the creation of a very strong and stable global market player in the fi eld of the modern CNC grinding machines. Our activities are focused mainly on the markets in the Czech Republic, Germany, Italy, Swi-tzerland, Holland, Canada, Scandina-via, as well as Russia, the USA, China and Australia. FERMAT Machine Tool Ltd. owns above standard production facilities covering an area of 5300 m2, equipped with modern technology, including precision machinery such as grinding

machines, slide-way grinding machines, horizontal boring and milling machines, and others. The company is thus quite independent in the production of key parts of machines. The quality of services off ered is supported by a wide business network of the group, its own design department, complete customer service and after guarantee service, and by a team of dedicated workers with many years of experience.

TABLE TYPE HORIZONTAL BORING MILLS

”There are many features of the FERMAT machine that allowed us to improve our effi ciency. Value for the money was an important consideration and Fermat machines are excellent value for the money. The features of the machine, for example: large box ways, planetary gear boxes between the servo motor and each of the ball screws, choice of CNC controls and well known, high quality purchased components all infl uenced my decision to purchase Fermat WFT 13 CNC machine. Sales

support from the Fermat Factory as well as from the local dealer was excellent, the company responded with information quickly any time it was needed.”

Jerry Decker,

President of Precision Boring Company, USA

WFC 10, WFT 11, WFT 13 and WRFT 130 represent the table type of horizontal boring mills. Chief machine characteristics are a powerful milling and drilling chip removal rate (even with top Y-axis stroke) and higher precision than other machines available on the market. A modular concept allows great operational variability in confi guration, built according to the client’s requirements. Modern control systems provide very easy operation of the machine and many useful functions for the user. Horizontal

Boring Mills WRFT off er 5 linear axes travel (X, Y, Z, V, W ) and 1 rotary axise (B) while WFT and WFC adopts the movement on 5 total axes. Given additional optional accessories, it is possible to increase number of controlled axes. During the metal processing, the column of the machine adopts Z-axis movement (with the exception of the WFC model) and the workpieces are clamped on a rotary table that travels in the X-axis.

”We have now seen that big boring mill on linear guideway is works very well. Also when working with spindle and ram out, and the machine is economical compare to hydrostatic machines, and also Fermat machine have long stroke on spindle 1000 mm/39.37“. We fi nd the service well with quick response as well, and also the technicians in Fermat help us to improve smart solutions where we save cost. After 5 years of using FERMAT Horizontal Boring Mills in Sæby we

decided to order the 7th fl oor type WRF boring mill as we got a new order for heavy parts subcontracting for wind power industry.”

Michael Jacobsen,

President of Nordmark Maskinfabrik A/S, Denmark

One of the main characteristic of the FERMAT fl oor type horizontal boring and milling machines is their powerful milling and drilling chip removal (even at the top of the Y axis stroke) and higher precision than is off ered by other machines available on the market. The large variation of selectable parameters is combined with its broad range of operating functions. The main feature is a modular conceptthat allows greater production variables and rapid set-up through the use of peripheral tools and accessories. The machine moves in 3 or 4 diff erent axes (X, Y, Z and W for borers). An additional B and/or V-axis is added when the machine is equipped with the rotary table. Several clamping

plates can be joined together, or in combination with a rotary table to achieve specialized confi gurations easily and quickly. Work pieces can be clamped either on the additional rotary table, on the clamping plates, or using both these possibilities. The main working purpose of the machines is chip removal from large and heavy steel, cast steel, or cast iron work pieces. The machine’s technology allows a wide utilization in milling, boring, reaming, and threading processes. FERMAT machines stand out thanks to their capacity to achieve higher precision than their competitors.
