One may suppose that stainless steels do not stain. Yet, you will be mistaken if you think so. Stainless steels do not stain as easily as other iron metals. However, they are not actually stainless. Similar to standard steel, it is possible to mark out stainless steel through fingerprints and oil. They lose their color…
Bottoming does not seem as widespread as before. However, well-informed operators have to master efficient and safe ways of performing it. Question: At the workshop, we still face troubles related to over-bending, particularly with certain material types and parts. We have been bottoming some parts to provide a 90-degree angularity for bends. We are considering…
Even the most advanced press brakes and tools have to handle variations of materials. Question: Our company has acquired 2 new press brake machines. Despite the fact that they offer many options, do not actually meet our need. We still face problems, such as the inability to perform angle repetition. The tools we have are…
Question: I have been dealing with a complex workpiece (shown in Fig. 1 and 2) which is a steel of 3/16 inch thickness. The workpiece bears stiffening ribs on the left as well as the right sides, which are descending flanges of 90 degrees with 4 inner bends. Inner bends stretch obliquely, rather than parallel…
Materials of fine grades save fabrication time and costs on press brakes. In our previous articles, we looked into the brain matter in sheet metals and plates, into their formation as well as the reasons for their sizes and orientations. Herein we are going to investigate the grain influence on the formation of materials on…
Quick and correct toolset in the press brake leads to more part production by operators. Press brakes continue to remain a major restriction in manufacturing shops. This matter has become even more acute over the recent ten years due to the intensive application of laser cutters of high flexibility and productivity. Long set-up for press…
A thin sheet component is usually understood as a workpiece obtained by the weld of steel sheets no thicker than 4 mm (such as stainless steels, zinc sheets, tins), for instance, hangars for roller installation, driver’s chambers, excavator chambers manufactured in our factories. High technologies are required to monitor and escape weld distortions of thin…
Fabrication and Installation of Large Air-Conditioning Ducts The crackle of air ducts leads to improper connection of air ducts, air outflow affecting the effects of air conditioners. Related to the fabrication control of large-scale air conditioners and their installations, the below-delivered aspects are identified.  1. Raw Materials Designing of an air duct takes flex force…
1. Power density This aspect appears a most crucial parameter in laser machining. Due to the power density the face layer is exposed to heating up to the boil point in microseconds. This will result in significant evaporation. Consequently, density of higher power is especially effective when your task is to punch, engrave or cut….
In the production process, a part of stainless steel frequently encounters deformity because of welding. Deformity of parts appears just on the surface, which depends on the effects of weld heat sources. The welding metal and the zone exposed to the heat get overheated easily. This brings about a large-grain effect for welding metals and…
