While purchasing a new press brake machine, tooling is the first to be considered. In the press brake choosing process the most important are tool style and shape methods. Not beginning from this point will bring about a mistakable situation. The matter is whether the new press brake has got new tooling, whether it works…
Precision of shaped pieces depends on tooling. Tools of press brake machines may sometimes be considered not so important during metal formation process. Press brake machines have developed becoming multi axes, accurate machinery that are featured with self stabilization, however tool is the accessory touching immediately the piece in bend process. Different tools possess characteristics…
In case it is necessary to bend metal plates in straight, parallel lines, sheet bending machines offer the best solution. Possessing electrical or hydraulic drive unit (very rarely manual), these machines allow producing quick and precise bending along straight edges with full width of the sheet forming elements of different profiles and pieces: bends and…
Practice and steel properties. Most press brake workers select V-die opening out of their practice while implementing particular task. Though their selection is based upon practice, it may also bring about fabricated metal sheet improper performance, which in its turn will lead to producing a defective eventual work piece. Steel is an admixture containing combined…
Pre-production process Selection is made in accordance with customers` demands as well as internationally established standards. Molds are fabricated by inner workshops, which make use of innovative technologies and operate top quality equipment and employ skilled operators and workers. Materials should be selected appropriate to every design. Production. Preparing materials. Fabrication process begins by first…
This material is an admixture, which contains iron, composed of two, maybe more chemical components. It has a vast application scope. Containing chrome, which makes generally 12-20 % of admixture, it is highly rust-resistant. The number of stainless steels established as model alloy is above fifty-seven. But there exist some producers that make proprietary alloy….
Sheet rolling device rolls plate metals in cylinder, arch or other work piece forms. It has a wide application in boilers, ship building, oil and chemical industries, metal structures, mechanic manufactury. Four-roll bend device is characterized with a suitable centeral adjustment, little extra direct edges, precise circle corrective, great effectiveness and ability to finish pre…
While cutting metals various workpiece materials are identified. Each material has got a perticular cutting technique as well as removefeatures. We need to manage all characteristics of each material. ISO regular metals fall into 6 categories, and every single one of them possesses certain features related to processing. Let us consider each separate type. P…
Plasma cutting machine nozzle is exposed to a mechanical pressure, thermal and magnetic constriction of plasma arch through splattering plasma gas, so as to increase energy thickness and impacting strength to accomplish the cut process. Plasma nozzle arch functions as an arch guide. During the operation electrodes serve as cathode, the nozzles as anodes. As…
Bend formation is realized in plate metal elements formation and it is efficient, suitable in terms of performance, time saving and costs needed to process elements. Nevertheless, because of inproper understanding of bend procedure working staff usually use traditional methods to finalize element formation, for inctance manual or hydraulic formation. These methods raise processing costs…
