Your specialist for precision forged parts

Precision forged parts are forged parts where very narrow tolerance can be achieved by following the forging process permanently. Our processes enable forging with the +/- 0.1mm tolerance. We are specialized in the production of precision forged parts weighing between 0.001kg and 1kg made of different material. The advantage of precision forged parts is that they can be used mostly in different compounds and without additional mechanical machining. Hot die drop forging is the method in our company – sticks are heated and inserted into the appropriate forging tool.After the forging process, we trim and pierce the semi-finished products to meet many shapes and other requirements. We shape stainless, alloy and carbon steels. In most cases, more complex and larger forgings are further machined.Due to the specificity of precision forgings, we provide the minimum necessary additional machining and thus reduce the machining times. After mechanical treatment,replica watches the products can be further smoothed by the vibrafinish process. If necessary, the products are thermally treated and the desired surface protection is performed (treatment “Magni”, electrolytic galvanic protection, KTL surface protection)

We are experienced in the production of parts made of different material. The majority is made of stainless steel. Moreover, we manufacture products made of hardened material of 64 Hrc.The manufacture is carried out on three different types of turning machines:

• Classic turning machines (14 machines). Turning machines are of different sizes and different complexity. The machining is carried out by using sticks of different diameter with automatic feed. Products with diameter up to 64 mm from sticks or 165 mm from pieces can be machined. The length of the machined part can reach 118 mm. The most technologically advanced lathe can machine with two spindles and three turning machines, which can move in three axes and can carry 12 tools each, for a total of 36 tools. All tools can be driven. Driven tools can produce up to 40 Nm of torque. All tools are controlled by a tool monitor, which ensures timely replacement of the cutting tool and minimizes deviation. Temperature compensation is the key to greater process stability. The main spindle rotates up to 4000 turns.

• Vertical CNC turning machines (3 machines), intended for bulky machining. The diameter of machined parts can reach up to 200 mm and up to 200 mm length. The turning machine can bear 12 tools. Of these, 6 may be driven. The main spindle produces 18 kW and can rotate up to 4500 rpm. The driven tool reaches up to 15Nm of torque and can rotate up to 6000rpm. The stable base and reliable machine construction enable machining of the pieces in precision within +/- 0.005 mm.
• Long turning machines (Swiss type) (8 machines). Machines are intended for long thin products and are mostly used for the production of beams made of different material. The reached shaft tolerance is up to H7. The workpiece diameter can reach up to 32mm and lengths up to 320mm. Linear positioned tools are a guarantee for extremely fast tool change. Under optimal circumstances up to 40 tools can be inserted into the machine. The spindles can rotate at 8000 rpm. One spindle produces 7.5kW of power while the driven tools produce 1kW of power.

Only high-quality steel is appropriate for high-quality products which are mostly assembled in the cars of our customers. By using hot forging process, we shape different types of carbon steel, all types of alloy steel and most of the time stainless steel.The Hot forging process and thus the transformation of steels has a number of specific points in its process. We have directed the development of forging into forging stainless steels, as these steels are increasingly present in automotive engines as well as in other segments of the use of forged parts. The advantage of stainless steels is that they are corrosion-resistant, and do not require additional surface protection. Through the hot forging process, we are able to transform both ferritic, martensitic and austenitic stainless steels.

Complete solutions with modern software and highly skilled employees

 With knowledge gained in past years we can provide you with a complete solution – from the idea to the final product. We cooperate with customers from the beginning, from the idea and this is how we contribute to faster solutions in the field of implementation of forged parts into the final system.Modern software and highly skilled employees are keys for the good-quality, fast and expert construction of complete tools and compounds.To design and program machines we use Siemens NX and Visi Vero software, which enable us to read and write data in several possible forms:

NX files, Solid Works files, IGES, PARASOLID, STEP, SXF, DWGBy using conversion modules, we can also open and save:CATIA, Pro / E, Inventor and STLTo achieve the shortest possible time from development to final products, we use modern software for simulating forging. We have a QForm product in use, a synonym for forging simulations. With its help, we anticipate the forging process itself already in the development phase, thus preventing subsequent corrections, and related deviations from quality and timing.

By using serial tools for the production of prototypes we can save your time

The prototype pieces are the key for the efficient serial production. This is why we pay a lot of intention to all prototype processes as well as all processes before the serial production. This phase is intended for taking down all data and information which are vital for the implementation in the serial production.
